2018 Honda Odyssey Complaint Log

This has been an ongoing issue with the sensors on the sliding door. When closing the door, it would start to close half way, then opens. This makes it really unsafe for children or anyone sitting next to the door as it would open unexpectedly or not close all the way without having to physically pull the door to close. When walking away from the vehicle, sometimes the car would lock automatically (as it should) but there are also times where the door would automatically open when walking away and things has been stolen from the vehicle because of it. The sensors on these sliding doors has been a real safety issue.

monocular camera code set and several dash messages - failure of ACC, FCW, LKA

On April 20, 2026, at approximately 12:00 pm. I was driving my 2018 Honda Odyssey (VIN [XXX] ) southbound on [XXX] , approximately 3 miles north of the junction of [XXX] and [XXX] . I was traveling at approximately 30 mph. The vehicle struck a pothole in the road. Immediately upon impact, the passenger-side curtain airbag deployed with a loud report that I described as sounding like a gunshot next to my right ear. There was no collision with another vehicle or object, and no warning of any kind preceded the deployment. I was startled by the sudden deployment and noise, and the vehicle briefly swerved before I regained control. The deployed passenger-side curtain airbag completely obstructed my visibility through the passenger-side and right-rear windows. The road at that location runs along a narrow embankment with no shoulder, so I was unable to safely pull over. I had to continue driving approximately 3 to 4 miles with severely compromised visibility until I reached a safe location to park near the 9W and 340 junction. I was the sole occupant at the time of the incident. The curtain airbag deployed directly adjacent to my child’s car seat, which was installed in the rear passenger-side seat. My child was not in the vehicle at the time. Given the force and location of the deployment, a child seated in that position could have been seriously injured. Following the deployment, I experienced ringing in my right ear and ear pain that persisted for several hours. I was also significantly shaken by the incident. Component that failed: Supplemental Restraint System (SRS) Electronic Control Unit (ECU), which caused inadvertent deployment of the passenger-side curtain airbag. The vehicle and deployed airbag are available for inspection. Safety risk: The inadvertent deployment created multiple safety hazards. First, the deployment itself startled me and caused the vehicle to swerve at 30 mph on INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Multiple times of driving the vehicle as I am trying to press the gas pedal while driving it acts like it is not working and suddenly it stutters and stalls. The car will shut off and put you into to neutral while you try and pull over to the side of the road without being hit. It happens randomly and without rhyme or reason. After it shuts off codes are thrown such as brake failure, emissions failure, hill assist failure, steering failure, and lane assist failure. The car will be really hard to restart and if eventually will and then everything will disappear and go back to normal. Codes leave and car drives fine until it messes up again. First time it happened was months ago from this report, and then it happened monthly, weekly and now almost daily but only when you try and drive. Very unsafe and there’s no reason cars should stall at high speeds going down interstates!

I have a 2018 odyssey EXL I been getting messages from right sliding door problem and during the drive after 12 or 13 miles was getting sign was saying stop the vehicle and door sign is keep flushing saying right sliding door problem

Paid $210 for Honda to run a diagnostic to tell me my multi purpose camera has a failure. This has caused 11 error lights to be displayed.

My car has started breaking randomly without reason. Just a few days ago it slammed on the brakes. I was driving on the interstate and went around a bend, and my car slammed on the breaks. I. Talking from 70- 5mph in seconds. I didn't have time to do anything. Nothing in front of me, nothing on the side. The car behind me had to swerve into the median to avoid hitting me. My car almost caused an accident. Im honestly afraid to drive it. Im not sure if the radar system is an issue in other Hondas, but if i was in an accident it would have been my fault. If the person behind me wasn't paying attention my children could have been seriously injured or worse. Please look into this issue. Its more dangerous than the other recalls.

While driving on a clear road, with or without heavy traffic, the collision mitigation warning shows up on the dashboard display. Sometimes the warning for the collision system goes off and the system tries to brake and jerk the wheel. If I have the wheel firmly I can correct it and it resolves. It can happen on a clear road with no one around or in heavy traffic. Yesterday it happened in a single lane with barriers on both sides, a road around Logan Airport in Boston, with no vehicles ahead of me. The car tried to steer me into the barrier. I was doing less than 25 MPH. The warning had been going off for a while but now that the steering and braking are involved it’s much more serious. I reported it to the dealer. They said they did a system check and couldn’t find a fault. The braking and steering problem first occurred about a month ago. The warning by itself has been happening intermittently for over a year. This happens even when the collision mitigation system is turned OFF. This is a terribly unsafe issue. If my wife had been driving I don’t know if she could have corrected. PLEASE ACT AND ISSUE A RECALL!

Our 2018 Honda Odyssey repeatedly and without warning completely loses acceleration power, creating extremely dangerous driving conditions. This occurs in two distinct situations:(1)while driving at highway speeds when attempting to change lanes or accelerate, and(2)when stopped at a stop sign or intersection and pressing the gas to merge into or turn into traffic. In both situations, pressing the accelerator results in little to no response — the vehicle will roll but fails to accelerate as needed. These failures have placed our family in multiple life-threatening situations. On Interstate 285 in Atlanta, Georgia — one of the busiest and highest-speed highways in the country — our vehicle has failed to accelerate during lane changes on multiple occasions, nearly causing serious accidents. Most recently, within the past week, my husband was driving on I-285 when he pressed the accelerator and the vehicle had absolutely zero acceleration response. He narrowly avoided a collision. We have also experienced complete loss of acceleration when turning from a stop sign into traffic and when merging — situations where immediate acceleration is critical to safety. The vehicle lags for several seconds before any power is delivered to the wheels, leaving us dangerously exposed in oncoming traffic. All manufacturer recalls have been completed, including the fuel pump recall. The problem persists and has not been resolved by any dealer service or recall repair performed to date. We are aware that this is a known, widespread defect affecting 2018 Honda Odysseys equipped with the ZF 9-speed automatic transmission. Hundreds of other owners have reported identical symptoms to NHTSA and to Honda directly. Honda has acknowledged the transmission's behavior to some owners but has stated it is "how the car is supposed to drive" — a response that is wholly unacceptable given the documented near-accidents this defect is causing.We are requesting that NHTSA open or expand its investigation

When driving the transmission is slipping meaning it jerks forward when accelerating on the road.

Car shifts out of drive and reverse to Park randomly. It also doesnt shift out of first gear on a cold start. I have to stop the vehicle, shift back into park and turn the car off then on again before it will shift out of first gear.

Power Tailgate Failure/Dead Battery from Body Leak. currently power tailgate is not functioning.

I am writing to formally report an issue with my 2018 Honda Odyssey. I recently discovered water seepage in the rear trunk area, which has caused moisture buildup and potential interior damage. After researching the issue online, I learned that many other 2018 Odyssey owners have reported the same water‑leak problem, indicating that this may be a known manufacturing or design defect. Despite similar complaints, I have not seen any acknowledgement, recall, or official response from Honda addressing this issue. As a long-time Honda customer, I am disappointed that such a significant problem—one that can lead to corrosion, mold, and electrical complications—has not been proactively addressed. I am requesting: An inspection and repair at no cost, as this appears to be a widespread defect. Clarification on whether Honda is investigating or planning to address this known issue. Assurance that any related damage caused by the water seepage will also be covered. I take pride in maintaining my vehicle, and I expect a reliable, defect-free experience from a brand like Honda. I hope Honda will take this matter seriously and provide a prompt resolution

Tailgate door is not functioning. Tailgate problem message on dash. Cannot open door with remote nor manually.

Rear hatch power door issue indicated on dash display, and complete failure of powered door feature. Investigation finds many other drivers of this make/model/year have issues with faulty seals allowing water intrusion into circuitry in left rear panel where the power lift fat control unit box is, causing damage to the circuitry. Other drivers have described more widespread electrical issues, some even causing the gate to unlatch while the vehicle is in motion. Upon inspection of my personal vehicle, signs of water damage were found both in the base of the area covered by the panel and within the circuit box and panel itself, confirming these suspicions.

While driving on the highway, the engine light came on and off. Pulling over, I inspected the engine compartment and heard what I believe was cylinder knocking, but could not obtain an engine code with an OBD code reader. Oil was of sufficient level as it had just been replaced within 1,000. After this I attempted to drive it to the dealership, where on going 45 MPH, I pulled to the right lane for emergency police vehicles and when the vehicle was stopped, the engine stopped and seized up. After not being able to start the vehicle, I could not find the neutral safety switch to put the transmission in neutral to move the vehicle from the flow of traffic (turns out the switch is not readily accessible and is on the side of the transmission underneath the air intake and battery compartment. Police officers pulled behind the vehicle and assisted me in getting a tow truck to take the vehicle to the dealership for inspection. At Coggin Honda in Jacksonville, the vehicle was inspected and the engine would not turn over manually by the crankshaft. The engine was deemed to have catastrophic failure and would need to be replaced at 126,000 miles. This vehicle is a 2018 which is on TSB 24-003, however is not listed on the applicable VINs. This TSB is for connecting bearing rod failure which would lock this vehicle’s engine the way the dealership found it. I believe this to be the issue as several Honda engines have had this failure. The vehicle was maintained per Honda’s maintenance programs and even had an extended warranty of up to 100,000 miles which when the TSB the vehicle was underneath that mileage and would have been covered by Honda if they had released the full list of VINs for that year to be inspected instead of a sub list of VINs of the production. Honda needs to be investigated to see if that TSB needs to be expanded since 2023-2024 timeframe other users have had a similar failure and seized engines.

My Odyssey began to shudder and misfire. Luckily, I was in a parking lot when it happened. It stopped running. Several attempts to restart were unsuccessful. Once when it did start, it was missing and would barely move. After about 15 minutes, I was able to get it started and get home (a little over 2 miles). I installed my code checker to find the problem. I initially had 22 codes - including P0301-P0306, P0300 and P0087. I waited a while and re-ran the test. The P0087 continued to show. I did not attempt to drive it anymore until the next day, when I took it to Canady & Branch (Auto Repair). They checked for codes and also had the P0087 code. They called and informed me of the issue and indicated that it involves the fuel pump. They also indicated that there were recalls for the Honda Odyssey for the fuel system:fuel pump. I contacted Priority Honda to determine if this would be covered under a recall. I was told that the recall did not involve my Odyssey. I needed my vehicle, so I had Canady & Branch make the necessary repair ($874.42 - the diagnostic was an additional $77). I spoke to Honda USA today and was informed that they do not cover 3rd party work and reiterated that my vehicle was not on the recall list. I was told that IT HAD BEEN on the list but was removed in March of 2024.

2018 Honda Odyssey rear tailgate problems, What was the issue? Problem is because water is leaking from the roof rails onto the tailgate module, causing the power liftgate control unit to short circuit, leading to unintended opening/closing or complete failure.I checked every fuse and my tail gate still wont open! tailgate module failed due to leak on the roof rail. The "holes" are three very small spots that the weld didn't cover.......

Noise coming from engine. No engine light nor warnings otherwise. Van was taken to dealership where it was confirmed that a rod bearing inside the engine assembly is faulty, which could cause sudden stalling of the vehicle, even while traveling at high speeds on the highway. This is a known issue (Honda Service Bulletin 24-003) with this model van manufactured at the same time, for which a national recall notice was issued. However, my vehicle’s vin was not included in the recall.

Upon further investigation, LOTS of 2018 Honda Odysseys are experiencing the same problem I am. There is a leak coming in from the top of the van in the rear that causes water to leak through and overtime damages the control unit in the back. Damage to this causes my power lift gate to completely stop working, my passenger drive door to stop working, and a bunch of features like the front collision warning, the lane departure, sensors, fog lights, so on to fail and go on and off. I had problems here and there with it but it wasn’t until it rained 4 days straight that I made the connection with the leak and started trying to figure out the problem. I took it to the Honda Dealership to get diagnosed and they confirmed this problem. We have not been in any accidents to cause body damage to the vehicle.

Intermittent electrical failure with the front monocular camera confirmed via DTC codes. Upon inspection, Camera is hot to the touch and all ADAS systems on the vehicle cut on/off with warning lights while driving. Was going down interstate utilizing ACC, system cut off throwing warning codes, then disappeared, then came back on. System continues to have intermittent issues indicating a failing camera. Even after 1-2 minutes of idle - camera is extremely hot when touching module underneath decorative garnish.

Power lift gate and power sliding doors failure alerts keeping showing up. They flash on and off on the display even while driving which can be very disruptive. The issue occurs randomly every few weeks The dealer quoted close to $2000 to attempt to fix it

One week ago, I was driving on a highway, accelerating to the 65 MPH speed limit on that road, my van's accelerator completely stopped responding. Despite pumping the pedal repeatedly, I was unable to control my speed at all, and the car continued to lose speed. I had my three children in the car at the time, and given that people regularly go in excess of 70 MPH on that road, I was in danger of not being able to exit the road and/or being hit. I was able to coast off of onto an exit, and the car started responding at speeds of 30 MPH, but it was lurching and jerking while driving. We immediately had the vehicle inspected by an independent mechanic and have been advised that the transmission needs to be replaced. There were no warning lights for this failure. The car also had an incident about a year ago where all lights came on and it stopped responding. At that time, we had Honda dealership examine it, and they said they could not find any issues. Additionally, the car has been jerking slightly while shifting, but the issue improved when we had the transmission fluid flushed at the Honda dealership again about a month ago, and no issues were noted by them at that time. We have performed regular maintenance and safety inspections on this vehicle.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving at various speeds, the message "Right Sliding Door Failure" was displayed. The contact was forced to pull over and manually close the door for the door to latch securely. The failure returned after the contact resumed normal driving. The contact stated that a message in red stating "Stop Immediately" and another message "Right Sliding Door Failure" was displayed while driving at highway speeds. The vehicle was taken to the dealer where the contact was provided estimates for a diagnostic test and the repair. The contact was referred to the NHTSA Hotline by the dealer to report the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 134,000.

The Camera module failed in our van and gave us a U3000-49 code which caused the vehicle to lose Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), and Road Departure Mitigation (RDM) functions on the vehicle with a cost to fix from Honda of $ 2,475.56.

The contact owns a 2018 Honda Odyssey. While driving at an undisclosed speed, there was a loud sound coming from the vehicle with unknown warning lights flashing on the instrument panel. The vehicle was drivable during the failure. On another occasion, the brake warning light flashed on the instrument panel, and the brakes slightly depressed independently, and the driver then fully depressed the brake pedal. The vehicle was taken to an independent mechanic, where it was diagnosed with a monocular camera failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 125,000.

I am filing a formal safety complaint regarding a dangerous manufacturing defect in my 2018 Honda Odyssey EX . A structural failure of the factory roof seam sealer (ditch molding) is allowing rainwater to pour directly into the vehicle's cabin, severely compromising critical electrical modules and creating major safety hazards. This water intrusion has caused two distinct and dangerous electrical failures: 1. Entrapment Hazard (Power Sliding Doors): Previously, water leaked into the rear fuse box area, causing the power sliding doors to completely fail and become completely unopenable. Transporting a [XXX] and a [XXX] in the rear seats, the sudden inability to open the sliding doors creates a terrifying entrapment hazard. In the event of an accident, fire, or emergency, I would be unable to evacuate my young children from the rear cabin quickly, posing an immediate threat to their lives. 2. Cargo and Security Hazard (Power Tailgate Control Module): Currently, the water leak has short-circuited the Power Tailgate Control Module. The system operates erratically: the tailgate automatically pops open as soon as the engine is turned off, and it refuses to open manually. Beyond the security risk, this electrical short could cause the tailgate to unlatch unexpectedly while the vehicle is in motion or stopped in traffic, potentially dropping cargo onto the roadway and creating a crash hazard for other drivers, or allowing carbon monoxide exhaust to enter the passenger cabin. This is a well-documented and widespread structural defect affecting many 2018-generation Honda Odysseys. Water destroying critical safety modules (doors and tailgates) is a severe design flaw that goes far beyond normal wear and tear. I strongly urge NHTSA to open a formal investigation into the roof seam sealer failures on the 2018 Honda Odyssey. A safety recall is necessary to force Honda to repair the structural leaks and replace the compromi INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle previously received a manufacturer dash wiring recall repair. After the recall repair was completed, the vehicle began experiencing intermittent and cascading electrical and communication failures across multiple integrated systems. Affected systems include Apple CarPlay, the DVD system, in-vehicle camera systems, CabinWatch, and repeated “MOST network unavailable” error messages. These failures occur intermittently and result in multiple systems disabling simultaneously. The vehicle was inspected by a Honda dealership, which confirmed the issue involves wiring within the dash harness. The dealership stated the affected wiring is not sold or serviceable separately and that correction would require replacement of the entire dash harness, but that this portion of the harness is not included in the original recall coverage. Because these systems share common power and communication pathways, failures cascade across multiple modules. When the camera system fails, rear view camera functionality and related warnings are unavailable while backing up, reducing the driver’s ability to detect obstacles, pedestrians, or children behind the vehicle. When CabinWatch is unavailable, the driver is unable to visually monitor children seated in the rear rows while driving, which affects situational awareness and the ability to respond quickly to unsafe conditions inside the vehicle. These failures also impact driver information systems and create intermittent loss of critical visual feedback, increasing driver distraction as systems drop out unexpectedly while the vehicle is in operation. The condition began after the recall repair and appears to be related to or a continuation of the original recall defect. The vehicle remains available for inspection, and the condition has been confirmed by a manufacturer-authorized dealer.

Engine failed while driving, will no longer start. Mechanic believe it is either connecting rod or main bearing failure. It has not been inspected by the manufacturer and will be sold to another person as is. No warning lamps or messages were present prior to the failure and didn't appear until after the failure.

The multipurpose camera that works to provide all the safety features failed In less than 8 years. These should be lasting for the life of the vehicle. There should be a recall for this.

I am reporting a safety incident involving the power sliding door system on my 2018 Honda Odyssey. Today, Monday, February 9th 2026, my 3 year old child’s arm was caught and compressed by the power sliding door. At the time, she pressed the interior door button while I simultaneously pulled the exterior door handle. The door began to open, my child placed her arm out, and the door then closed on her arm instead of reversing. The door did not release or reverse automatically. I was unable to open it using the exterior handle and had to stretch to the front dashboard, left sliding door open button to stop and reopen the door to free her arm. Thankfully this didn’t happen on the passenger side sliding door! This resulted in redness, swelling, and pain, and she later woke from sleep crying due to increased pain. She is undergoing medical evaluation. The vehicle is equipped with pinch protection sensors that failed to prevent this injury. This appears to be a serious safety malfunction involving a child. I am submitting this report so the issue can be documented and reviewed for potential investigation. I have not seen a recall involving the sliding doors sensors having this issue.

Upon pressing the accelerator from a complete stop, the vehicle does not respond right away. The main incident was when traveling around 50 miles per hour on a highway, the van shifted into neutral on its own and the accelerator would not respond. An error message of transmission failure showed on the dash briefly. The van had to coast through traffic an eventually push off the road.

This is in relation to Investigation PE25008. The engine in my 2018 Honda Odyssey Elite failed at 91,307 miles due to a connecting rod bearing issue, despite perfect dealership maintenance.

Before my vehicle reached the 100,000-mile mark, the check engine light began appearing intermittently. I brought the car to my local dealership multiple times, but they were unable to provide a diagnosis and repeatedly reset the light. Once the light remained on permanently, the dealer finally identified a known Honda recall/extended warranty issue and replaced the spark plugs at no cost. However, approximately six months after that repair, the check engine light returned. The dealership has now diagnosed a failure in both the front and rear catalytic converters at a cost of $5200 to replace them. I need to replace to pass my state of Illinois car emissions tests. I have been working with Honda Goodwill Assistance (Case #161-655-70), but their offer to cover only 20% of the replacement cost is unacceptable. This failure is not a standard "wear and tear" issue; it is a direct consequence of the spark plug issues I repeatedly attempted to address before my warranty expired. I was told the 20% determination was based on my vehicle exceeding 100,000 miles, but this fails to account for the fact that I brought the car in for this specific issue multiple times while it was still under warranty. I am looking for Honda corporate to acknoweldge the new spark plugs they directed my dealer to install caused this issue and cover the cost of the repairs. My local Honda dealer service manager, Brian, is willing to speak on this issue on my behalf. He can be reached at [XXX] .

Vehicle lags in acceleration from a slow rolling start, at random times. There is a clear 1-2 second lag in the acceleration, then a sudden harsh shift into gear. Mostly happens during turns, and if traffic is present, may cause an accident. Also when traveling at low speeds 20-35 mph, there is a transmission jutter. Have spoken with service reps at dealerships and they claim to have no knowledge of these transmission issues

Defective body seam on roof panel over drivers side rear wheel - resulting water leak on control panel for power liftgate caused the rear tailgate to continually open and close while driving. The vehicle was parked and the fuses controlling the tailgate were removed to enable the closure of the hatch and allow vehicle operation. Prior to this, the vehicle battery died while parked due to the continuous tailgate operation and required a battery jump. The vehicle was taken to D&J Auto (an independent service center) where a previous liftgate control panel was replaced for failure to open the tailgate. A search of the internet on 2018 Honda Odyessey liftgate problems revealed multiple instances of water leaks on the liftgate control panels due to body seam issues which caused liftgate failures. This information was relayed to the auto repair shop where the leak was discovered. The vehicle was taken to a body repair shop across the street where the seam was fixed, returned to the auto repair shop where a third tailgate control panel installed.

A small "knocking" noise was noticed a couple weeks or so ago in my 2018 Honda Odyssey. Noise got progressively worse. Vehicle was taken to the Honda Dealership for assessment/repair. Was notified by a service technician that a rod knock was present on the lower end of the engine and that the engine needed to be replaced. Options were: new engine, used engine, or trade in my vehicle towards purchase of a new one. All maintenance records are meticulous and performed by a certified Honda service department.

We turned the car on and got an ACC, LKAS, FCS, AHL errors due to the front sensor and the camera failing. This is an issue that many Honda owners are dealing with. The issue will not allow you to use cruise control and will disable 90% of the safety features we bought this vehicle for. The car drives fine but the safety of those in the car is affected by this error and needs to be recalled due to the number of complaints of this issue. There were no errors or warning signs prior to this happening.

Front camera is known to go out on these vans causing ACC, LKAS, Collision mitigation, road departure mitigation system, auto high beam, transmission problems and more.

Engine has a rod knock problem at 72,000, miles. Vehicle will likely need a full engine replacement.

Vehicle experiences engine stalling and failure to restart at intersections when the Auto Idle Stop (AIS) feature is engaged. This creates an immediate life-safety hazard as the vehicle becomes non-functional in live traffic. This has occurred 2 times. Once on surface streets and once on the highway in stop-and-go traffic. This issue persists despite Service Bulletins 23-008 and 23-009. Honda Corporate and Honda Dealership refusing to cover the repair. Separately, during a 37-day repair attempt (Jan 22 – March 2, 2026), AutoNation Honda Chandler admitted the vehicle was sold with an 'incorrect' battery type (Lead Acid instead of required AGM), which caused electrical instability. The dealership attempted a repair on Feb 13, but the vehicle failed to start again on Feb 11 during a pickup attempt. The dealer has since refused to provide accurate service records or further communication. The vehicle remains unsafe to drive as it continues to stall randomly.

Our 2018 Honda Odyssey (Elite) has been diagnosed by our local Honda dealer with engine failure due to rod knock (rod bearing failure). This vehicle is well maintained with only 72,500 miles when the issue became noticeable. The dealer has verbally quoted $8,800 to replace the engine with another used engine, which I refuse to pay given the relatively low mileage and age of this vehicle (and history of other costly inexcusable issues). I opened a complaint/goodwill case (#16188784) with Honda Corporate, which was denied. This Honda Odyssey was our primary family vehicle (the only vehicle we can all travel together in), and it is now siting in our garage completely inoperable. Honda America's lack of care here is beyond frustrating.

After I received a software update for my 2018 Honda Odyssey Elite the car has been stalling when idle. It is very dangerous because I will be at a stop light in drive, and the vehicle will shut off with no power. Cars will be behind me or no cars, and I have almost been rear ended. I did not have this problem until I received the new software update. It keeps occurring more and more often.

2018 Odyssey EXL engine seized up at 111k miles. There's now a bunch of metal shavings in the oil. The engine will not turn over.

My car needs a complete engine replacement due to "rod knock" or "bottom-end failures." It's my understanding that some Honda vehicles were recalled due to this (Recall 23V-751). And that there were other vehicles having issues beyond the scope of this recall (Query RQ24013). I'm disappointed because my Honda mechanic and independent mechanic have cited my impeccable service records and have told me there is nothing more I could have done. This feels fraudulent.

Water leaked through manufacting seams on rear drivers side of roof causing tailgate module to malfunction and creating a safety hazard. The rear tailgate would not stay latched or function at all. Took vehicle to honda of Bristol and they confirmed the problem.

My 2018 Honda Odyssey began exhibiting intermittent acceleration lag several years before the repair, and the condition progressively worsened. At the time of repair, the vehicle had 68,957 miles. The safety concern occurs when accelerating from a stop, such as at a red light, stop sign, or when merging into traffic. I depress the accelerator normally and the vehicle does not respond. There is a delay where the engine and transmission fail to engage, leaving the vehicle stationary while surrounding traffic begins to move. To compensate, I must press the accelerator further. When the vehicle finally responds, it does so abruptly, causing a sudden surge of acceleration. This creates two safety hazards: (1) loss of control due to the unexpected “kick” when power finally engages, and (2) increased risk of collision when attempting to merge or cross traffic, because the vehicle does not accelerate when expected. I have been honked at by other drivers and have experienced near‑miss situations because the vehicle failed to move when it should have. Owner forums show many similar reports from other ~2018 Odyssey owners describing the same acceleration lag and abrupt engagement. Based on these reports, the commonly recommended fix is a throttle body cleaning and a transmission “teach‑in” procedure. An authorized Honda dealership performed these procedures on my vehicle at my expense (approximately $500–$550). These procedures are not listed in Honda’s factory maintenance schedule, yet appear necessary to correct a drivability issue that presents a safety risk. Given the frequency of similar owner reports and the safety implications of delayed or unpredictable acceleration, this issue may indicate a design or calibration defect in the throttle body, engine air‑management system, or transmission control logic.

Since I own this vehicle, 3 times tailgate failed. I have done repair it twice in Honda dealership at Paramus NJ. Now it happened again after a year of last fix. Instrument cluster = Warning sign appears stays there. Somewhere on back = Constantly sound beeping - When driving Tailgate = Does not open and if open some how, it does not close. Neither automatic nor manually. I have to drive vehicle since I have no choice. I inspected all fuse in front under hood and in rear at cargo area.

The contact owns a 2018 Honda Odyssey. The contact stated that while stopped at a stop light and attempting to make a left turn on an exit, there was a knocking sound coming from the engine. The contact called 911 and the Fire Department; however, there was no fire. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and it was determined that the engine and starter needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 23V751000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The manufacturer was notified of the failure and confirmed that the VIN was not included in the recall. The failure mileage was 167,000.

I own a 2018 Honda Odyssey Elite. While driving to ER for my daughter engine started making weird knocking sounds, when I stopped at a red light to turn left off the interstate Odyssey just died and began to smoke. My daughter and I were advised to get out of the vehicle for safety reasons, due to smoke. There was no warning lights or any other indication that the Odyssey had a problem. 911 was contacted fire and police responded, it was determined that engine reached max temperature. Odyssey was towed to Honda dealer for diagnostics, it was determined that connecting rod bearing was bad and long block needed to be replaced, starter also imploded and needed to be replaced. I contacted manufacturer to ask for a "Goodwill Repair" due to NHTSA Campaign Number 23V751000. Per manufacturer Honda would not offer any assistance for the engine repair even though recall matches exact part affected in the recall. All regular maintenance oil changes, 100,000 mile service, new tires, have been performed on the Odyssey. I can provide receipts and records. The failure mileage was 167,384.
