2018 Honda Odyssey Complaint Log

The adaptive cruise control, automatic emergency braking, lane keep assist, and other safety functions associated with the front camera failed. These safety features are a huge part of the vehicle and doesn't feel safe to drive. The front camera has failed in under 6 years and is currently being replaced by the dealer to hopefully fix these issues. The repair is not covered by Honda.

We started hearing a metal knocking type noise on start-up and acceleration. We took it to a mechanic who diagnosed it as a rod-bearing problem. Then we took it to the Honda dealership thinking it was related to recall 23V751000 which also deals with 2018 Honda Odysseys, but for some reason our VIN was not included in that recall even though our problem sounds exactly like what is mentioned in the recall. The dealership said we are 6 months out of warranty and would therefore need a new engine. I used one costs $9,000 and a new one would be $22,000.

Multiple warning lights came on, indicating a failure with the front camera sensor attached near the rear view mirror. Errors include: auto high-beams, lane keep warning, collision mitigation system, road departure warning, brake system, and adaptive cruise control failure. All problems stem for the single point of failure - the front-facing sensor/camera located at the top of the windshield. Replacement quotes are $1,800 - $2,500!

Regularly maintained my Honda Odyssey Elite. Suddenly get warnings for all safety elements while driving - 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. Dealership wants me to change out the radar sensor in the front which seems to be the root cause. Lots of other Honda Odysseys having the same safety issue as reported on NHTSA website.

During a normal drive on city road, the right side airbag and copilot passenger seat airbag both activate with no collision or agitation of the vehicle. Vehicle was sent to dealership for inspection; data transmitted to Honda USA. Honda USA replied that it is normal for airbag to activate even if there is no collision; Honda said even a speed bump could activate the airbag. Honda has refused to investigate further or compensate my repair. During the incident, the car was not going through any speed bump; it was just on a normal flat city road. There was no prior warning signs in the car. It could have caused significant personal injuries had my kids were sitting next to the airbag explosion because the bags activated with.no collision; there is no counterforce to the airbag thus it would thrust straight into a person. Luckily my kids were not in those seats at the time. It took so long to file to NHTSA because Honda had been very unresponsive after hearing my case, it took Honda half a year to inform me they are not doing any corrections or compensation to this incident.

ACC,LKAS,Collision Mitigation System, Road Departure Mitigation System, Auto High Beam warnings. All read problem and do not go away

There are times especially when first starting the car that pressing the gas does not move the car from a stopped position. There is quite a delay and sometimes a need to turn the car off and back on for the car to move. This can be quite dangerous when stopped and then crossing lanes of traffic as it is unknown when this delay between pressing the gas pedal and the car actually moving may occur. This was reported to Honda service who advised it is normal for this car to have such a delay.

Engine has been “hiccuping” for a few months and making a knocking sound. Brought it to Honda on 3 separate occasions and they “could not replicate” the sound. And said it’s normal. I’ve had 2 non Honda mechanics look at it and they agree it sounds like a rod knock and engine failure is going to happen sooner rather than later.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving at various speeds, the message "Engine Management System Failure" was displayed on the instrument panel. In addition, the contact stated that the vehicle hesitated while depressing the accelerator pedal, with an abnormal clicking sound coming from the vehicle. The contact had taken the vehicle to an independent mechanic and was informed that there was a failure with the engine and the transmission. The dealer was then notified of the failure and the contact was informed that there were no recalls on the VIN related to the engine or the transmission. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 150,000.

Failure of the Front windshield mounted monocular camera from overheating causes all advanced driver assistance systems to shut down such as automatic emergency braking, adaptive cruise control, lane assist, etc. This is a very common occurrence in not just the Honda Odyssey, but other Honda models as well. A new part can be anywhere from one to two thousand requiring dealer calibration. The heat from the sun, the location of the monocular camera and possible contribution from replaced non-OEM windshields may contribute to the overheating. With all safety devices disabled, the vehicle becomes unsafe to operate requiring immediate attention and dealer only service since a new device requires calibration.

Several warnings popped up on my dash at once: adaptive cruise control, lane keep assist, brake system, auto highbeam, collision mitigation system, and road departure mitigation system. The dealer’s Internet is down for at least several days, so they are not able to troubleshoot the problem. However, an internet search to troubleshoot myself indicates that this is a standing, systemic issue with 2018 and 2019 Honda Odyssey’s that may warrant a recall.

Forward collision warning comes up on vehicle. There is a problem with the transmission. the car automatically shifts itself from D to S.

Engine noise, dealer service indicated that its the rod bearings, since I have never ever had this problem on any other car I have owned in 50 years i did a little research and immediately found lots of information and a recall for this problem but my VIN is not included but its exactly the same problem identified in the recall

My trunk was working anymore. I could not even open it manually. I had a shop that only works on Acura's and Honda's look at it. The control module for the trunk was wet and fried. I dont understand why it was wet in the first place since it was in seal box. This should be a recall on it. Please see attach pictures. I paid $669 to have them replaced it.

All of our sensor controlled equipment is not working. LKAS, ACC, Forward collision, auto brights, etc.

Our 2018 Honda Odyssey has continued to experience power sliding door issues that were initially addressed by NHTSA campaign numbers 18V795 and 20V437000. Our vehicle underwent the recommended repairs in both campaigns. The vehicle is available for inspection upon request, and the problem was reproduced by a dealer. In short, after undergoing both warranty repairs, the same problems gradually cropped up again. When attempting to close the door with the power-close button, the sliding door would sometimes stop about three-quarters of the way, and then open fully again. This would happen even when nothing was obstructing the sensor. This happened on both sides of the vehicle (i.e., both sliding doors), and eventually the doors ceased working altogether (albeit at different times) and we brought the vehicle to Honda for a non-warranty repair. The dealer was able to reproduce the problem in both doors, and they made the necessary repair in both cases (see attached invoices). Now, very similar issues have cropped up again, and our concern is that the initial warranty repairs may not have sufficiently addressed the root cause of the issue with these sliding doors. Once again the door sounds like it isn't latching completely. It's hard to describe, but everyone knows the sound in a vehicle when a window or a door is cracked just a little bit. The sound is exactly like that. The dealer told us that moisture intrusion and/or a latching issue may have caused this problem, and we also experienced a severed cable. Word for word, these are almost exactly the issues that campaign numbers 18V795 and 20V437000 were intended to address. If these are indeed the same issues that were the focus of the two recalls, then our vehicle is at risk of the same safety failures, i.e., the sliding doors opening while driving, failing to latch, and/or the snapping of the outer door handle cables due to moisture intrusion.

My 2018 Honda Odyssey Elite as faulty camera system above rearview mirror according to our local Honda delaer. The dealer is asking for $1700 to replace this item. It is causing multiple warning lights (5) on the dash and now adaptative cruise control, lane keep assist, brake system, and other systems are no longer working. Multiple Honda Odyessey owners are having this same issue. We need help getting this issue corrected/fixed by Honda as a recall.

I bought new and have 59,000 miles on the car. During the past year or two, when I get to a stop sign and about to cross or turn into a busy road (that has no traffic signs for the cars traveling on that road), the car hesitates when I step on the gas pedal, then after a second or two, the car lurches forward (abruptly) while screeching the tires. My analysis is that there is something about making several complete stops in short succession (as a driver would do in an attempt to inch into a busy intersection of fast moving traffic in order to get a better view and position the car for a smoother merge) which triggers the car to stall for a second or two. I say this because it does not happen at any other types of intersections. The danger here is that a second or two is crucial in avoiding a crash when you are trying to merge into a gap in traffic. Then after hesitation, the car lunging forward in an uncontrolled manner can cause an inexperienced driver to loose control of the vehicle during a turn. There are many similar complaints filed with NHTSA and posted on online owner forums. Many owners have reported to Honda, but Honda’s response is that this is how the car is supposed to drive. NHTSA, where are you? We need help on this

Prior to purchasing this vehicle, On the test drive, the vehicle slammed on the brakes for no good reason. The dealer assured me the collision mitigation braking system (“CMBS”) can be turned off, so I bought the car. I then learned that the CMBS automatically turns on every time the engine is turned on. I must shut CMBS off each and every time I start the car, but since my other car is a Tesla (which doesn’t have this problem), sometimes I do forget to shut off CMBS. Through out my almost 7 years of ownership, the car has slammed on the brakes COUNTLESS numbers of times for absolutely no reason at all. Sometimes no cars are behind me, but there have been several times when cars behind me have almost crashed into me due to my faulty CMBS. My elderly mother is in need of a car and I refuse to let her borrow mine because I am scared she will forget to disable the CMBS and get into a crash. I am deeply astonished that with everything that is known about Honda’s CMBS, NHTSA has not taken any action against this dangerous feature. I wonder what NHTSA is getting paid to look the other way. A complete failure of an institution I used to hold in high regard.

The contact owns a 2018 Honda Odyssey. The contact stated while driving 10 MPH, the accelerator pedal was depressed; however, the vehicle failed to respond as intended. In addition, the check engine warning light was illuminated. The vehicle was taken to the dealer; however, the vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The failure mileage was 82,000. Parts distribution disconnect.

the right sliding door has had intermittent malfunction for years. often, the door will not work with an automatic function and must be pulled open or closed manually which is nearly impossible to accomplish. most often the right sliding door malfunction notification appears when driving at highway speeds which is extremely unsafe. this has been inspected by the dealership and no fix or resolution was provided. recently, all of the ADAS systems are intermittently malfunctioning. they work about 1 out of every 5 times the vehicle turns on LKAS, Auto Braking, Adaptive Cruise Control, are all affected. within the last week the internal camera system has been failing, audio stops working, and most importantly the rear hatch has been closing on its own while i am standing underneath it loading the trunk. this is also very unsafe, it atleast beeps to warn that it is closing but i sometimes barely have time to get out of the way. yesterday while driving in the highway, two warnings appeared simultaneously for “transmission system problem” and “blind spot notification system error”. the vehicle started again without the transmission system or blind spot error but i am very concerned about the degrading electrical system issues that i have been experiencing with this family oriented vehicle model.

There is a water leak in the body of the van (where the top and side are welded together). The water has caused damage to the electrical panel that controls the back door/liftgate. The water damage is also shorting out and causing electrical damage and the battery to die very often. I have noticed many complaints about this. I believe this should be a recall because it is a flaw in the making of the vehicle and nothing I could have done to prevent it.

Random multifunction camera failure triggering lots of errors. Needed to pay dealership over 2000 to fix. Safety issue as it disables blind spot detection, lane change, collision warnings etc

This complaint is related to the recall issued for the fuel pump repairs. The car hesitates when starting from a stop. The hesitation is alarming enough during left turns to avoid on-coming traffic. The dealer and Ameican Honda has been made aware of this. However, the local dealer is refusing to prioritize the repair. The local dealer (Economy Honda of Chattanooga) states that they will prioritize the repairs only when the car comes to complete stop. With this kind of policy of the local dealer, I do not know when the repairs will be done. The car is used to transport four children and the family. Please help getting the repairs done as soon as possible. The safety of children and the family is at stake. This occurs all the time when the car is used. This car had two issues: 1) Fuel pump recall 2) Fuel injector warrantee repairs. Attached is a letter to the dealer about both problems. The dealer has addressed the fuel injector warrantee repair issue. However, they are totally refusing to prioitize the fuel pump repairs unless the car comes to complete stop. The dealer has been made aware of the issue in a letter dated June 20, 2024 written by my father Also, a case has been registered with American Honda in this matter. American Honda is refusing to do anything until the dealer prioritizes the reapairs. Neither American Honda or the dealer are priritizing the repairs and expects us to drive the car under current unsafe condition. Please help.

I have a 2018 odyssey and have only had it for about 6 months. One of the biggest issues I’ve noticed is when I go to accelerate, the car does not go right away. I have to push down hard on the pedal and the tires spin, resulting in the van lurching then accelerating quickly. This has caused MANY moments of panic as I’ve gone to accelerate to pull into traffic or to drive across a main road and it’s stalled for a moment then lurches into accelerating. I’m a careful driver and have always used acceleration in moderation and try to ease into it. This van does not allow that. You will try to press down on the pedal to slowly accelerate with nothing happening, then it’s like it connects and plows forward. Tires spinning and all.

At critical accelerating situations (turning, merging, passing...) the minivan will hesitate, and no power is delivered to the wheels. As a result, the car does not perform as intended and can cause an accident when turning, merging, or attempting to pass. The only resolution is to remove any pressure from the accelerator and allow the car 1-2 seconds to recover, then you can usually accelerate slowly. Sometimes this has happened multiple times in the same accelerating event. This happens on 2018-2019 Honda Odysseys with 3.5l V6 with ZF 9HP transmissions. This has happened multiple times and Honda has failed to correct this issue. This is a known issue and has been part of a class action lawsuit. The most recent incident occured yesterday and the vehicle automatically shifted into Neutral and would no long drive.

2018 Honda Odyssey failed transmission systems. This vehicle had recalls in regard to TCM module and softwares in past. Normally transmission system should last well over 150,000 miles for this type of vehicle. My car failed at 74000 miles. That too without any advanced warning. Vehicle was maintained and serviced at same dealership regularly where it was purchased. Honda is claiming its outside their 60000 mile powertrain warranty. Honda expects me to pay over 10,000 dollars for repair. I believe my vehicle is having issues with transmission related to TCM module recall of 2019 and Recall 04v176 of 2023. Honda is refusing to look in to possibility of my vehicle's issue could possibly related to those recalls. I believe those recalls need to be looked at and my vehicle should have been involved in those recalls. I have documented proof for all services performed and current vehicle inspection report.

Dear NHTSA Team, My Honda Odyssey 2018 EX has been having issues with my Driver side Sliding door opening/closing using the Auto power. It was randomly sometimes not fully closing (kept reopening). Then it would get fixed automatically . This was happening for 3+ years . I had got the open recalls done over the years. This week it just stopped opening suddenly . And it was not getting resolved either manually or even after turning ON/OFF car . I took it to Honda Dealership in Dublin, California . They said error code B2049 the left slide door motor and door cable , latch were all faulty. And it would cost about 2500$. This was very expensive and I asked them to just put the door back and they charged the labor cost of 730$. When i look up online I see in forums multiple customers having such issues in this 2018 to 2020 odyssey model. My car hasn't been in any accident and my door is in great condition visually, so it has to be some faulty mechanism with the door as I am first owner and have taken great care of the car. I have records of oil changes, tire changes and other maintenance over the 6 years of ownership. Request NHTSA team to help look into this as it may be some rework during the different recalls to fix the sliding door or a manufacturing issue still not fixed. This can be dangerous as customer needs a functioning door to enter/exit out of Van. Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The forward camera sensor used in the 5th generation Honda Odyssey Touring is experiencing high rates of failure, especially in hot weather. This causes failure of the Adaptive Cruise Control, Lane Keeping Assist, Collision Mitigation system, Road Departure Mitigation, and Auto High Beam systems. The part number of the camera is 36160-THR-A72, 36160-THR-A73, or 36160-THR-A74 depending upon the date of manufacture.

Rear backup camera stopped working. Currently there is an active recall for 2018 Odysseys on all trim levels vin specific but somehow our vin number isn’t covered under the recall. I followed service bulletin 20-060 and it fixed the problem.

All of my safety sensors no longer work. Warning lights for all sensors are on at all times.

Initial issue was that the power tailgate would not open at all. Took the vehicle to the dealership where they replaced the latch and the control unit that was completely fried. When I asked what could cause that, they said they didn't know. I already suspected water. Two days after picking the vehicle up from the dealership, the tailgate is now constantly opening and closing on its own. The only way to stop it is to turn off the vehicle and lock it. I searched online and found multiple posts from people with the exact same problem and almost all of them say it was water getting into the control unit. This poses an obvious safety concern since it could close on one of my kids. They would not be strong enough to stop it. I have reported the issue to Honda HQ and have recommended that the other people with the issue do the same.

The contact owns a 2018 Honda Odyssey. The contact stated while driving 70 MPH, the vehicle independently decelerated. The contact stated that several unknown warning lights were illuminated. Additionally, the contact became aware of a knocking sound coming from the engine compartment. The vehicle was taken to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced or repaired. The vehicle was not repaired. The contact was informed of an unknown recall with a similar failure; however, the VIN was not included. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 98,000.

The tailgate malfunctions and the car does not register the tailgate as closed even if it is closed. The power tailgate ceases to be operational and the locks do not work. The cause is a defect in a seam which allows rain water to reach the control unit for the tailgate. This was confirmed after an inspection at an official Honda dealer. This is a safety issue because it renders the car inoperable. The “tailgate open” warning signs and sounds flash. There is currently a Honda “Engineering Request for Investigation” released. It can be accessed at the following link: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Crack in body seam above driver and passenger side of the tailgate AND underneath the roof rail cover caused water leakage. This resulted in a short of the power tailgate control module which draws down my battery and causes unexpected trunk closing during normal use. Family members have been hit in the head by the trunk due to the unexpected automatic emergency closing.

While driving, the transmission will go into limp mode and will not drive over 40 mph. Comes on and off intermittently. Will not show error code. Was almost rear ended by semi trailer when happened

Tailgate malfunction due to water seeping through tailgate resulting in tailgate module to stop working.

While driving down the interstate, the engine started to make a loud squealing noise. I pulled over to investigate. Not being a mechanic, I couldn't determine anything. I attempted to start going again and the engine had no power. I was barely able to get it off the highway and we called for help. In the van were me, my wife, and daughter. It was scary with cars and semitrucks driving past us at high speeds. I was concerned. We were able to get the van towed after several hours of waiting. It was a hot day and I had a tick on me while waiting. The van took over a month to repair. The dealership confirmed the cause of the engine failure as the cylinder #2 connecting rod bearing. There were no warning lights when we pulled over the first time. When we started going, the check engine light came on.

VIN: [XXX] Manufacturer Recall Number: KGS NHTSA Recall Number: 23V-858 2018-23 FUEL PUMP MTR SAF RECALL EXP2 The local dealer "Ourisman Honda of Tysons Corner" mentioned that there is a shortage of parts needed to address the recall listed above and has asked me to wait indefinitely. I would like to have this recall fixed as soon as possible. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Started up the van and the following appears on the dash: ACC problem Collision Mitigation Problem Automatic speed control problem Lake Keep Assist Problem Auto High Beam Problem No prior issues.

Vehicle stalls when pulling out into traffic! Terrifying with my 6 kids and I'm immediately getting rid of this vehicle. Tried to have the fuel pump (current recall) replaced but Honda dealership has the vehicle for 6 DAYS! and still didn't have the part in. Upon dropping the vehicle off the tailgate lift would not work properly. This van is a load of garbage since they started using so many modules to control it! Extremely disappointed in Honda. They know all of these faulty parts and don't care enough to fix them for the safety of the consumer. Absolutely horrifying the direction of the automobile industry.

Why has there not been a recall on Honda Odyssey's multi camera in windshield - it seems this is happening to many autos. These are ALL Safety issues that should be resolved by Honda. Dealership says it will cost me $2000 to have this repaired. Let me remind you that I had not even made a payment on this auto when the transmission went out while still under warranty. I had not had it a full month when this happened. We are grandparents raising our grandchild, we purchased this automobile for space for carseats and such, thinking it was a very safe automobile. Now many of the safety features no longer work! Not only are we on a fixed income but raising a child is not cheap! Auto High Beam Problem, Road departure Mitigation System Problem,, Collision Mitigation System Problem, Lane Keeping Assist Problem, Adaptive Cruise Control Problem, Brake System. These are constantly flashing on my dash.

Knocking noise began so I took it to a Honda dealership. They said I have a “lower knock noise” and need a new engine because a bearing went out for a rod which could cause my engine to seize. Though there is a recall for some 2018 odysseys, I’m being told mine isn’t covered. Apparently there are many more people with the same vehicle and the same issue as me. I’d like to see this included in the recall

The lane keep assist function via the monocam behind the windshield has failed causing an alert to show up a few minutes into driving that none of the systems related to it are functional. This appears to be a widespread problem amongst owners of the 2018 Odyssey. Additionally, Honda service centers are acting like this is a surprise to them but searching online will results many individuals with the same issue and then being charged 1300-2000 to fix it. Since the features are all safety related I assumed this was where I should submit this. Please let me know if this is not the case. See the honday odyssey forums for many people noting this problem... [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle started to show warning: Collision MitigationSystem Problem/ Road Departure Mitigation System Problem/ Adaptive Cruise Control Problem / Lane Keeping Assist Problem/ Auto High-Beam Problem. I took it back to Honda dealership and was told the Multipurpose Camera is damaged and needed to be changed. They asked if I have a vehicle accident and I told them I HAVE NOT BEEN IN ONE. I don’t understand why this just starts up all of a sudden and have seen other people complaining of this same problem.

our honda odyssey 2018 elite - has a failed windshield monocular camera - original part (36160 - THR - A73) failure is a u3000-49 error. This failure causes most of the advanced safety features of the vehicle to not be operational. see these dashboard errors: Collision Mitigation System Problem Road Departure Mitigation System Problem Auto High Beam Problem Adaptive Cruise Control Problem Current repair cost from a dealership can exceed $2000. I've researched many forums and this seems to be a very common problem among Honda Odysseys of similar year range. I fee like Honda should issue a recall and replacement for owners since this involves many of the saftey features of the vehicle and cost is very prohibitive to fix for many of us.

We encountered a total engine failure while driving down a Montana highway in our 2018 Honda Odyssey. In the car were my partner and I, an elderly person, and a child. We had to wait over 2 hours for a tow truck in extreme heat in a dangerous location. There were no warning indications before the failure.

1.5 weeks after servicing vehicle at the dealership (oil change and tire rotation) Warning lights come on beeping upon starting vehicle. The following systems are malfunctioning... -collision mitigation syatem problem -adaptive cruise Control problem -lane keep assistance problem -road departure mitigation system problem -auto high beam problem. This also removes any ability to use regular cruise control in any capacity (even without adaptive cruise control on) Honda certified mechanic diagnosed code : U3000-49 as a bad Multipurpose Camera Unit. Parts alone cost $1,200 then labor and cost to calibrate (which must be done at dealer). The cost of this repair to MAJOR safety features would be over $2,000. This is a safety related issue that should be recalled immediately. We do not currently feel safe in our 2018 Honda Odyssey, nor do we have $2,000 to complete this repair. Our research (a few screenshots attached) of this malfunction of the Multipurpose Camera Unit shows widespread issues on 2018 odysseys in particular. To me that warrants an investigation and recall. A dealer actually told me "you don't need those features to drive the vehicle". Well, we don't NEED a backup camera and it was recalled. Why? Because we don't want to run over small children. I would like to be able use ALL safety featured on my vehicle. This isn't an entertainment system. It is the major safety feature on our family vehicle, which we saved for years to purchase. We ask that Honda consider the safety ramifications of NOT recalling this malfunctioning camera unit and do the right thing in issuing a recall.

Soft or Low Brake Pedal The brake pedal have a soft feeling and travel to the floor with low effort. This is causing low braking performance and increased pedal stroke. This condition is increasing the risk of a crash.

2018 Honda Odyssey front camera failures. We bought it brand new and found out today that front multipurpose camera was not working properly. There are bunches of warning lights popped up on dashboard: LCC, LKAS… problems. I went to Google and Facebook to see there were so many people have the same problem particularly with this 2018 models. Dealership wanted $1800 to replace camera and they know that was Honda technical issues, not in customers control.
