2018 Honda Odyssey Complaint Log

My right sliding door stalls intermittently. It won’t open or close. My dashboard will read right sliding door problem. This has happened intermittently over the past 6-8 months.

2018 Power Tailgate Failure from Body Leak Tailgate stopped working. I read so many owners have the same problem.

A problem with the frame of the van in the rear/above the liftgate not being properly welded created leaking/malfunction of the liftgate and water remediation needed under the headliner. A significant safety issue was created-causing unprovoked opening and closing of the liftgate during operation of the vehicle both while parked and moving. Multiple times were individuals harmed during this process, as well as health issues from riding in the van during long period in an environment with mildew and mold development.

The rod bearings failed causing immediate decreased acceleration on [XXX]. I was going 70ph on the highway. I was fortunate not to have crashed. The dealer confirmed that the rod bearing failure was under safety recall for my exact 2018 odyssey, however, my VIN was no included in the VINs that were eligible for recall. [XXX] There was not any warning light or message prior to the catastrophic engine failure on [XXX]. Honda has denied my case American Honda Motor Co., Inc. Case #: [XXX] despite that fact that the car has been well maintained (records attached) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Multiple warnings occurred simultaneously when I started my car I been doing a research on the web I found out that many buyers have the same problem with their van's and already reported here is the list that found 2018 2019 2020 Honda Odyssey Touring and EX-L , I found out that the camera/sensor in the windshield (near the rearview mirror). It needed to be replaced. their camera has an internal failure!!! This needs to be recalled

The windshield monocular camera is completely non functional causing several dashboard errors to appear. It very disheartening as this is such a known issue within the Honda Odyssey community and very expensive to replace and get calibrated after replacement. This should be recalled since so many are having this issue. Clearly this is a fault of Honda. It seems that the camera can get too hot being in the windshield and just doesn't work. A big reason why I wanted this vehicle was because of these sensors. Now I can't use them.

Improper seal on exterior driver side roof near trunk lift gate. Allows water inside during heavy rain or when going through a car wash and the water damages the control module for the power tailgate. Damage to the control module cuts off any use of the tailgate, even manually. This is a $900+ repair due to a MANUFACTURER ERROR

The contact owns a 2018 Honda Odyssey. The contact stated that while driving 30 MPH, the vehicle lost motive power and failed to accelerate as intended. The contact stated that an abnormal sound was coming from the engine. There were no warning lights illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the engine had failed. The vehicle was then towed to the dealer where it was diagnosed that the spun rod bearing had fractured, and the engine needed to be replaced. The vehicle was not repaired. The contact stated that on a separate occasion, while diving at 30 MPH around a bend, the Forward Collision Avoidance warning light illuminated. The vehicle was taken to the dealer and an unknown part was greased. The contact stated that the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 92,000.

The front camera has failed resulting in safety concerns including braking system and cruise control failure. This is a known issue with many new Honda Odysseys and needs to be recalled as it is not safe to drive as it disables all honda sensing and auto braking components on the vehicle.

2018 Odyssey Elite with 43k miles. Apparently, the front facing camera failed and if the camera fails -- which seems to have been reported by many other owners -- it's about a $1700 fix from a dealer. Not only should the camera not fail, but this is happening to cars that are low miles, low use, and the failure affects all camera-related safety features of the vehicle: lane keep assist, adaptive cruise control, lane departure warning, forward collision warning, parking collision warning, and automatic emergency braking.

On this 2018 Honda Odyssey, at 93000 miles, an abnormal noise started to occur under acceleration. Dealer diagnostic indicated the noise is coming from the bottom end of the engine, likely from the rod bearings. The dealer indicated that this specific VIN number is not included in the current Honda recall, however is exhibiting same symptoms.

Front facing camera malfunctioning, and it is available for inspection upon request. This malfunction causing 5 different warning lights to show up on dashboard. Including 1.) Auto high beam problem, Lane keeping assist problem, collision mitigation system problem, adaptive cruise control problem, road departure mitigation problem. The issue has been confirmed by the dealer. There were no warning lights prior to the random malfunction. I have not had wind shield replaced (which I have read could mean a calibration of the camera issue), nor has there been any accidents taken place. My safety is at risk as I am unable to use these features while driving unless the front camera is replaced.

My 2018 family van purchased brand new. Exclusively serviced at dealer. Immaculately maintained records kept. Driving 70 mph on toll road while driving to dealer for service, car lost power and had to be towed remainder of the way. 100k service done at dealer, 40k miles later car had to be towed back to dealer due to broken rods. Honda says my vin# not effected yet car is inoperable for exact issue with open recall effecting rods. Recall states cars effected produced 2015-2020. Honda offered for us to pay $10k for new engine and they would cover remaining $4k. We do not believe we should get stuck with larger portion of payment when Honda has a known issue with part. Research on line states many more cars affected than the 250,000 initial recall. We appreciate NHTSA’s 2nd probe into this issue.

The circuit board for the module that controls the power lift gate is damaged from water. Water seeps in the roof rail and wets the panel causing the the power tailgate to lock shut and unable to be opened.

Multiple warnings occurred simultaneously for the "brake system" intermittent. I have the same issue per [XXX] for my Honda Odyssey 2018 elite. I can see the same problem by a lot of people. I told Honda and paid them $220 diagnosis fees and they ended up asked me to change the whole camera that cost 4k. This obviously defect issue from Honda. Looks like known issue for this. Can this escalate back to Honda? For example [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a dangerous and recurring transmission defect in my 2018 Honda Odyssey equipped with the ZF 9-speed automatic transmission. The vehicle experiences sudden and unpredictable delayed acceleration, particularly at low speeds. When attempting to accelerate from a complete stop or at speeds below 25 mph, the transmission fails to engage properly, leaving the vehicle stranded in the middle of traffic with no power response for several seconds. This creates an extreme safety hazard, as other vehicles may collide with mine while I wait for the transmission to respond. The condition is intermittent and unpredictable, making it impossible to anticipate when it will occur. It happens most frequently when accelerating from intersections, merging into traffic, or navigating through slow-moving areas. Honda has acknowledged this defect through TSB 19-124 (issued December 2019), which addresses harsh and jerky upshifts in 2018–2019 Odysseys with the 9-speed transmission. However, the TSB does not fully resolve the issue. A class action lawsuit [XXX] et al. v. American Honda Motor Co., Case No. 5:23-cv-05011-BLF, N.D. [XXX] ) is currently pending for this exact defect. I am requesting that NHTSA open a formal investigation and consider issuing a safety recall, as the delayed acceleration constitutes a serious risk of collision and injury.

Upon starting the vehicle we get the following warning lights: Road Departure Mitigation System Problem Blind Spot Info System Problem Adaptive Cruise Control Problem Lane Keeping Assist Problem Transmission System Problem Collision Mitigation System Problem The vehicle is drivable but none of our safety features work. We took it to a local shop that was close and they said it’s a known issue with Honda and that the monocular camera located in the windshield is malfunctioning.

While driving certainly Air bag SRS problem information came up on the dashboard and never went away during my four hours of driving. I know this is a safety issue and so many accident happened before for failure of the air bags and people died. I though I should inform to NHTSA about this safety issue. I contacted the dealer and take my car to check this problem.

Went to leave my house at 8pm and the car was malfunctioning. Blind spot problem, parking sensor problem, road departure mitigation system problem, auto engine idle stop problem . Lights flickering on and off, console lights not working, can’t control heating speed. Light would not stay on as I was driving . I have a couple videos of the malfunction.

During rain and snow storms I will get warning lights that the power tailgate isn’t working. Last year when I took it into the dealer they said the tailgate would open and close randomly and there was water in the rear fuse box. I thought I fixed the issue by replacing all the wires from the rear all the way to the front. They fixed my tailgate and did water testing to make sure no water was coming in through the tailgate and all was great. Fast forward to this year and the middle of February we had an all day snow and rain storm and I start having these same warning lights along with a couple others. By the end of the day the tailgate completely stops working. I take it back to the shop that had originally fixed it and water is getting in. Not from the tailgate but through some unknown opening. The fuse board is completely corroded and we have to replace it again. They could not determine where the water is coming in from. I do not want to be driving down the road and have my tailgate randomly open and have items fall on the road causing injury to someone. Nor do I want to have to pay $1000 to fix the circuit board every time it rains or snows. I live in Utah it happens frequently.

My car has had all recommended service completed by the dealership since I purchased my Honda Odyssey in 2018. On 2/18/25, my power liftgate started malfunctioning. An error message beeps inside my car 4 times, every 4 seconds and cannot be manually turned off. I took the car to the dealership and was quoted $7500 to make the repair. My car only has 90,000 miles on it and has passed all of my previous service inspections. Supposedly, water is getting into the rear control module. I have never had water in my car so this is clearly a manufacturer's defect that is allowing water to seep into the rear control module.

There is a major safety issue that has happened a few times now. As I come to a stop, or come out of a stop, the engine stutters and completely shuts off. All electronics stop too. Immediately there is a message flashing “right sliding door problem.” I have to put my foot on the brake and restart the engine to get going again. This recently happened as the red light turned green, and a car almost slammed into me from behind.

There is water leaking in the body which damages the power tailgate control module located at the rear driver side. the tailgate doesn’t open and endanger people inside in case there is any accident.

I took my 2018 Honda Odyssey to the dealership for a fuel pump recall repair. The next day, the engine warning light turned on, and I heard a loud abnormal noise from the high-pressure fuel pump.I scheduled an immediate service appointment. The dealer charged me $230 for a diagnostic but claimed no fault or error code was found. They turned off the warning light without explaining why it was triggered.The abnormal noise from the high-pressure fuel pump persisted, and the dealer recommended replacing the high-pressure fuel pump for $1,942.78 while denying any connection to the recall repair. Component/System That Failed: High-Pressure Fuel Pump Engine Management System How Was Safety Put at Risk? A fuel system failure can cause engine stalling, leading to sudden loss of power while driving and an increased risk of a crash. Has the Problem Been Confirmed by a Dealer? Yes. The dealership acknowledged an abnormal noise from the high-pressure fuel pump but denied any connection to the recall. They only reported a DCA-8000 code, which is not a standard fuel system error code. Has the Vehicle Been Inspected by the Manufacturer? Yes. The dealership inspected the vehicle but refused to take responsibility. Honda Corporate was also contacted, but they denied warranty coverage. Any Warning Lamps or Symptoms Before the Failure? No prior issues before the recall repair. The engine warning light turned on the next day, and the abnormal noise from the high-pressure fuel pump began immediately after. Why This Needs to Be Investigated: The issue began right after the recall service, suggesting a possible defect. The dealer charged me $230 but failed to explain the warning light activation. If other vehicles experience this, it may indicate a recall defect. A fuel system failure can create serious safety risks for drivers and passengers. NHTSA must investigate whether the recall service contributed to high-pressure fuel pump failures, as this could pose a significant safety hazard.

Upon startup of the vehicle the following Warnings flash on the dash: "Auto High-Beam Problem, ACC Adaptive Cruise Control Problem, LKAS Lane keeping Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem." This problem is easily reproduced and occurs almost every time I start my vehicle. I had my battery tested and it was reported to be GOOD. The vehicle still drives correctly, but none of the safety features listed above work. If these features are going to be mandated on newer vehicles they should be reliable and function correctly. I will never buy another Honda vehicle!

In several occasions there is a delay in acceleration. This typically is happening when I take off from a stop sign and turning, others I have literally been on highway merging and loss all acceleration Al though I can hear rpm ramp up, there is no action till 10-15 seconds later. I am very lucky no was injured in that instance and could have been a terrible accident going 70+. I see this is an ongoing issue, and because it is not consistent in manner people fail to repair/research issue.

The contact owns a 2018 Honda Odyssey. The contact stated that when the vehicle was started, there was a loud vibrating sound coming from the engine compartment. The contact stated that when the vehicle was shifted into drive(D) and the accelerator pedal was depressed, the sound was louder. Additionally, the vehicle lost motive power during acceleration for approximately 10 minutes and then drove normally. The vehicle was taken to a dealer where it was diagnosed and determined that the high-pressure fuel pump needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic for a second opinion and the contact was informed that the high-pressure fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 17,163.

See attached document for complaint.

The front facing monocular camera has failed and my 2018 odyssey has less than 55k miles on it. Without the operation of this camera you cannot use the cruise control and the dash lights up with all kinds of warnings (lane mitigation failure, acc failure, brake light continuously on). This is a known faulty safety feature that is far to common for the newer odyssey models. This is ridiculous that Honda has put this system into their vehicles, in particular the odyssey and there needs to be a service bulletin to repair this issue or recall completely. It is obviously a faulty part and needs to be resolved.

The power tailgate has a failure. I took my minivan to a local mechanic who said the motor has failed. I tried to see if I could do the repair myself and came across a number of forums and YouTube videos that detail this is a known, reoccurring issue.

The vehicle has recently and suddenly developed a loud engine knocking sound which sounds like an engine bottom-end knock (crankshaft or connecting rod). The sound is dependent upon engine RPM and is most noticeable at low RPM and when the engine is warm. The knocking sound is severe for the first 1-2 seconds on cold engine start, until oil pressure is developed. There are two known incidents believed to be caused by this issue: 1. While driving on a public highway with a 75 MPH speed limit, the engine knock became severe and the check engine light began flashing. The car would not accelerate, and once speed was reduced it would not accelerate at all and "limped" home at much-reduced speed. Prevailing traffic had to take action to avoid colliding from behind. 2. While driving up a very slight incline on a public highway with a 65 MPH speed limit, the engine knock became severe and the check engine light began flashing. The engine was unable to produce power and struggled to climb the hill at around 33 MPH with prevailing traffic coming up quickly and swerving to avoid colliding. The vehicle "limped" home again. The problem has been confirmed by an independent service center specializing in Honda and Acura vehicles, and confirmed that the knocking sound does indeed sound like a connecting rod and referred me to Honda service bulletin 23-097. I called American Honda to inquire as to whether my vehicle's VIN qualifies for the associated recall, and they said the vehicle does NOT qualify, and that it was a very narrow range of VINs which do qualify. The vehicle has not yet been inspected by the manufacturer, police, or insurance, only the independent service center who did NOT open the engine bottom end for inspection, only listened and did non-invasive troubleshooting before referring me to Honda. Please add this to the Office of Defects Investigation's investigation RQ24013

The airbag system malfunctioned, causing the airbags to deploy unexpectedly while driving. The vehicle is currently at the Honda dealer for repairs and the airbags, as well as related components, are available for inspection upon request. The unexpected deployment of the airbags posed a significant safety risk. It startled me, which impaired my control of the vehicle suddenly as I was driving on the highway. Afterwards, I noticed fumes in the vehicle and I began feeling nauseous and light headed. I managed to pull over on the highway and stepped out of the vehicle. This could have led to a loss of control of vehicle, increasing the risk of collision or injury to not only myself but others on the road as well. The problem has not been reproduced or confirmed by a dealer or independent service center yet. However, my insurance appraiser inspected the vehicle immediately after the incident and confirmed that the airbags deployed without any signs of a collision or impact. The cause of the deployment remains unknown, and the appraiser recommended that Honda investigate the issue further to identify any potential malfunction in the airbag system. The issue has been inspected by my insurance appraiser, who concluded that while the airbags deployed, there were no visible signs of a collision or any impact that would typically trigger airbag deployment. The inspection of the vehicle’s exterior panels, undercarriage, and suspension showed no signs of damage. The cause of the airbag deployment is unknown, and the appraiser recommended that Honda investigate further to determine if a malfunction within the vehicle’s airbag system is responsible. I believe Honda is at fault, as this issue appears to be related to a malfunction that they need to address. There were no warning lamps, messages, or symptoms prior to the airbag deployment. However, after the airbags deployed, warning lights appeared on the dashboard, indicating a potential issue.

Regularly maintained my Honda dealership. Suddenly get warnings for all safety elements - adaptive cruise control, Lane keeping assist, collision mitigation system, road departure mitigation system, auto high beam headlight. Recommended to report as this seems to be a common thing with Honda and needs to be a recall.

My 2018 Honda Odyssey experienced a heavy snowfall in January 2025. The control panel displayed an alarm, Power Tailgate Problem , and the trunk door could not be opened. I asked a professional who pointed out that it is usually due to water intrusion into the control unit located on the rear driver's side body panel, which causes the tailgate to fail to open, close normally, or even open accidentally. They believe that this is a manufacturing defect caused by the manufacturer and there is a safety hazard.

They believe that this is a manufacturing defect caused by the manufacturer and there is a safety hazard. For safety reasons, I went to the dealer for an inspection. They said they could not find the cause but that the control panel was broken and needed to be replaced. I had to spend a lot of money to replace it. But I still think that the problem was caused by the manufacturer itself.

The Honda sense front facing camera has went out on my 2018 Honda Odyssey. The camera is currently still installed in my van and if it is necessary to replace to keep it from draining the battery I will request that the faulty part be provided to me. This camera being faulty causes the loss of cruise control, adaptive cruise control, auto high beams, lane keep assist and emergency breaking. This issue is also causing a drain on the battery, which impacts other items due to low voltage. My van is currently at the dealership and I am being told that I will have to purchase a new camera which will be around $1500. The following lights are on; BREAKS, ACC and LKAS. These items first appeared within a few weeks of having the rear camera recall completed. Based on my research this is a common problem and just like the rear camera recall, Honda should have to replace this camera as well. The date provided is the date it was officially diagnosed by Honda, the lights appeared in 10/2024 and all of the functions were lost around that time.

The Tailgate Control Module (TCM) was infiltrated with water due to a crack in the seam on the rear driver side panel. This caused the tailgate to be unusable and no longer latch as a result of no power to the tailgate latch. The TCM (Part #: 74970-THR-A12) had to be replaced as well as all seams needed to be sealed.

Several people have told me that they hear a banging or thudding heavy sound coming my 2018 odyssey engine. The sound frequency increases as the engine rpm’s increase. I have seen many reports that state that this symptom could lead to a total engine failure which makes the car unsafe and is caused by incorrectly machined crank shafts (oversized). I called Honda and was told there is no recall at the time ( 8/23/25). In my opinion there should be a recalled. There was not warnings presented. Another failure occurred when mice ate the fuel injector wiring. This caused the engine to malfunction . The cause of this failure I have been told was caused by Honda using wire with a soy based insulation which mice eat.

Power tailgate malfunctions. Random errors showing on dashboard and randomly attempts to open on its own.

Tailgate warning beeps. Tailgare Will NOT open or Close. Dashboard lites flash. Vehicle will NOT START ! CANNOT START or move Vehicle!

The seam seals on the rear driver's quarter panel of the vehicle are faulty and allowed water to flow into the cabin of the vehicle. The resulting damage was loss of function to the rear power lift gate, front seats, remote start and other key fob functions, as well as a dead battery(assumedly due to arcing on wet circuitry). The damage rendered the lift gate inoperable as I it initially closed but came open during operation. We continued to receive a power lift gae problem on the "Heads Up Display" but the power gate would not open or close, electrically or manually. After a few days the gate opened but would not close, rendering the vehicle unsafe to operate. Furthermore, the battery was dead and would not start. Had this incicdent not occurred in our driveway we could have been susceptible to being stranded in sub-freezing temperatures with kids. The vehicle was taken to a dealer and they confirmed a roof leak was a cause of the water incursion. The power lift gate module and floor harness were damaged causing failures to lift gate operation and other electronics. It will cost $7000 to have it repaired at the local Honda dealer. Pending completion of repairs and paperwork for submission.

Emission error code which is part of recalls due to Fuel pump and suddenly check Egin light came on and vehicle couldn't shift from Park Mode to Drive Mode. We took the vehicle to Dealer ship and they mentioned that transmission failure where vehicle just two weeks ago at the dealership for another repair and inspection report didn't specify anything about the transmission.

The Honda monocular camera is apparently causing malfunctions and or warning lights. This is impacting many Odyssey owners according to my research. This should be addressed by Honda and reimbursement or repair covered as a recall.

Up and down engine.

Did not control speed sometime up and down engine.

Did not control Engine up and down fuel nt work.

The rear tailgate stopped working. Upon investigation, there is structural issue with the body. There are holes near rear tailgate which allows to water to pass through. The water has damaged the rear tailgate motor and now the door is inoperable. This has been a common issue with Odyssey minivans 2018 and newer model. We have contacted honda regarding the issue and they refuse to accept any liability regarding the body defects.

Our 2018 Honda Odyssey minivan had water leaks intruding and collecting into the power tailgate control module on the driver-side rear compartment causing the tailgate to become nonfunctional and not lock properly or open/close appropriately leading to a major safety issue where the tailgate may open or even not close during movement of the vehicle leading to significant risk to passengers with respect to accident or bodily injury. This power tailgate issue appears to be caused by defective rear body seam seals from the manufacturer that allows water to leak into the rear driver's side panels and intrude into the module leading to damage and destruction of the module circuit board. I have needed to purchase a replacement for the module (~$200) and I have provided photos to show the water damage.

Fuel pump went out on my Honda Odyssey causing my car to stall on a highway with my kids. It kept giving me issues the last few days before stalling with taking off. It was as if the car did not want to take off when stopped and when accelrating. I did report this to my local Honda dealer and although there is a recall regarding the fuel pumps and injectors dealing with my make and model my vin number is unfor. not included. I had to have my car towed to my local dealership on 12/18 which I am still waiting on repairs. When this happened all of my warning lights appeared.
