1 Assist problem

Failure Date: 03/06/2026

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.

2 Assist problem

Failure Date: 12/02/2025

Camera projector fail and 6 warning ?? lights came on, very common issue.

3 Assist problem

Failure Date: 08/08/2025

5 major safety systems are automatically disabled and on further troubleshooting by the dealer, all these issues are pointing to a faulty front collision avoidance camera. The cost to replace and recalibrate the camera is upwards of $2400. This is absolutely ridiculous and seems like a safety recall issue.

4 Assist problem

Failure Date: 07/28/2025

The sensor/computer/camera on the windshield overheats and causes it to fail mines at 100,000 and its a $1600 repair dealer said because the windshield sits in sun while driving etc and the sensor overheats and melts the inside of the computer soldering. Unacceptable so much for my safety features all gone I dont have the money to replace.

5 Assist problem

Failure Date: 07/09/2025

The adaptive cruise control, collision warning, lane keep assist and other safety features have stopped working as indicated by errors displayed on dashboard. Suspect front camera is malfunctioning but has not been confirmed by independent service center. At first, this seemed to be an intermittent issue, but now the error messages appear every time the car is used.

6 Assist problem

Failure Date: 07/01/2025

The monocular camera behind the front windshield has failed resulting in all safety functions related to it (adaptive cruise, lane assist, blind spot, etc. ) failing to work.

7 Assist problem

Failure Date: 07/01/2025

The multipurpose camera failed bring down all driver assistance functionality including lane keep assist, emergency brake, auto high beam, parking sensors, cruise control, etc. Fix is outrageously high $2500+. Internet search finds this to be a very common issue and deserves a recall.

8 Assist problem

Failure Date: 06/01/2025

Suddenly the van gave me 5 different warnings as below. 1. Adaptive cruise control problem. 2. Lane keep asist problem 3. Collision mitigation system problem 4. Road departure mitigation system problem 5. Auto high-beam problem on top of these, 'brake system' light also turned on.

9 Assist problem

Failure Date: 05/22/2025

I have an intermittent set of warnings on Honda Odyssey 2018 "lane keeping assist problem" "adaptive cruise control problem" "collision mitigation system problem" "road departure mitigation system problem" all at the same time will appear on the dashboard. I had brought it up to the dealership when under warranty and they were unable to resolve it. It comes and goes at random.

10 Assist problem

Failure Date: 05/05/2025

Vehicle is indicating all sensing system not working such as lane keeping assist system, collision mitigation braking system, road departure warning system, adaptive cruise control and others. Honda installed a cheap product on this vehicle when it was originally manufactured and is double dipping by selling us in a 7 year period another set of the same cheap product . Dealer is quoting me $3,139. 80 to replace a radar and a camera both at the same time.

11 Assist problem

Failure Date: 05/05/2025

Driving on the freeway my lane keeping assistance, automatic emergency breaking, and adaptive cruise control warnings were flashing. The prompts keep my focus off the road as the beeps and flashing orange lights cannot be disabled. During my drive, the multicamera on the windshield seems to be malfunctions and often I would get a signal of on coming traffic and my steering wheel would vibrate to prompt me to move. This can be extremely terrifying and sometimes caused me to swerve, potentially hitting other cars. The multicamera needs to be recalled and fixed.

12 Assist problem

Failure Date: 03/13/2025

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.

13 Assist problem

Failure Date: 03/10/2025

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.

14 Assist problem

Failure Date: 03/10/2025

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.

15 Assist problem

Failure Date: 01/08/2025

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.

16 Assist problem

Failure Date: 11/14/2024

Multipurpose front camera controlling multiple vehicle safety features had internal failure. Dealer required replacement of camera and calibration. Multiple warning lights came on dashboard to alert of issue. Faulty camera was diagnosed by Honda dealer and is with dealer currently.

17 Assist problem

Failure Date: 11/04/2024

Monocular camera failed, all warning shown in the dashboard.

18 Assist problem

Failure Date: 11/01/2024

Adaptive cruise control, forward collision warnin, lane departure warning, and lane keeping assistance lights came on and won't go away. Sometime the car won't reverse when put in reverse.

19 Assist problem

Failure Date: 10/20/2024

Driving vehicle on the road, the suite of driver assistance system suddenly failed including lkas, front collision warning system, adaptive cruise control, lane departure as well as brake system light. I took the car to the dealership which indicated the front camera had catastrophically failed. This issue seems to be a recurring issue in all models of Odyssey minivans. The issue seems to appear for recent and older vans and is well documented in online forums. It should be a safety recall from Honda compared to other recalls on same vehicle.

20 Assist problem

Failure Date: 10/17/2024

Started my car and got all these warning lights acc problem, collision mitigation problem, lake keep assist problem, auto high beam problem. From reading forums online this is a common issue for Honda Odysseys 2018-2023. The camera is faulty. This should have a recall.

21 Assist problem

Failure Date: 09/23/2024

When I turned on the ignition to drive the vehicle, multiple warning lights came on to include failure of lane keeping assistance, forward collision avoidance, adaptive cruise control, lane departure warning, and automatic emergency braking. Additionally, after acknowledging these lights, the "brake system" light remained on in the amber color. If these safety features are not working properly, it can put the occupants of my vehicle as well as others at risk. We took the vehicle to the Honda dealer. They ran the diagnostics and stated that the fault was "internal electronic failure of multipurpose camera unit/internal failure of multipurpose camera". We had to replace the multipurpose camera and have the new one re-calibrated.

22 Assist problem

Failure Date: 09/19/2024

Vehicle started to display acc problem, lkas problem, trnsmission system problem, collision mitigation system problem, road departure mitigation system problem, auto lights problem and blind spot info system problem recently around September 19,2024 and disabled all the safety features mentioned on the vehicle while it is in motion. This is a huge safety issue and could cause severe problem for many drivers and passengers in case of serious accidents which could be avoided if those systems are functioning properly. Upon researching the issue, this is very common problem for many of similar vehicles and it seems to be related to the monocular camera on the windshield. I strongly urge for quick investigation on this matter and have Honda motors to do a recall for replacing faulty camera as it could impact many lives.

23 Assist problem

Failure Date: 09/12/2024

All of the safety features stop working intermittently on my van. The warning lights do all come on. Independent mechanic says the multipurpose camera unit has stopped working. Safety features that I thought I had are not available.

24 Assist problem

Failure Date: 09/10/2024

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.

25 Assist problem

Failure Date: 09/05/2024

Acc,lkas,collision mitigation system, road departure mitigation system, auto high beam warnings. All read problem and do not go away.

26 Assist problem

Failure Date: 08/29/2024

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.

27 Assist problem

Failure Date: 08/12/2024

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.

28 Assist problem

Failure Date: 08/01/2024

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.

29 Assist problem

Failure Date: 08/01/2024

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

30 Assist problem

Failure Date: 07/18/2024

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.

31 Assist problem

Failure Date: 07/11/2024

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).

32 Assist problem

Failure Date: 07/05/2024

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.

33 Assist problem

Failure Date: 06/07/2024

I was driving home and suddenly the lights with these warning signs just came on. Lkas, acc, collision avoidance, auto high beam problem ive heard from many customers complaining of this of 2018-2020 Honda Odyssey models.

34 Assist problem

Failure Date: 05/21/2024

The forward camera malfunctions and causes the cruise control, lane assist, and emergency breaking to be inoperative. After looking online, this is a frequent issue for this van. I believe it is related to the recent recall because it was functioning perfectly until right after we had the recall repaired.

35 Assist problem

Failure Date: 02/20/2024

The tailgate module has been fixed three times by Honda, along with the tailgate being resealed by Honda, however, the car continues to leak water through a seal in the drivers side upper rarea.
