2020 Honda Odyssey owner complaints

This is now the second time that we are having a rear hatch failure. with about 37,000 miles on this van, the control module shorted out due to water getting into it due to a bad seam (according to other Odyssey owners who are suing Honda for this). We could not get the hatch to open or close, so I paid the dealer to fix it. Honda did give us a check after the fact to cover some of the bill. Now, with less than 51,000 miles, it has happened again. The hatch will not open or close. In the event of an emergency, this is a major safety issue, to be potentially stuck inside the cabin. The hatch started going up and down randomly, and we could not control it. Now, it won't go up or down. This van is is a mess. Not only does it have this issues, but the rear back up camera still doe

FEDERAL SAFETY RECALL 23V-431 FAILED AFTER FOUR REPAIR ATTEMPTS - MULTIPLE SAFETY SYSTEMS NOW NON-FUNCTIONAL My Honda was subject to Federal Safety Recall 23V-431 (MOST Communication Cable causing backup camera failure). After FOUR repair attempts, the original defect persists AND multiple additional safety-critical systems are now failing. REPAIR HISTORY: August 7, 2023 (30,749 miles) - Honda San Carlos performed recall repair 23V-431. Dealer claimed issue resolved. October 5, 2024 - Original backup camera/infotainment failure returned. I documented with photo evidence but problem was intermittent. September 29, 2025 (48,038 miles) - Returned to Honda San Carlos. Same backup camera failure. Dealer attempted repair. November 18, 2025 (48,928 miles) - Returned to Honda San Carlos. Problem

The speakers of our Odyssey crackle and pop despite completing the recall (MOST bus connectors) recommended by Honda. It has progressed to affect the entire infotainment unit. The unit shutdowns repeatedly while driving which means that the backup camera fails, as well as any navigation one is using while traveling. The hands-free phone features are also affected as one cannot connect their phone to the car. We've attempted repairs at the Honda dealership but they have been unable to provide a permanent fix. Each time they try to replace a connector or un-kink a wire, the problem returns within days. Most recently, the battery died and the car was unable to start due to the constant restarting of the infotainment center.

The auto slide door latch will not disengage. The rear passenger door cannot be opened electronically OR manually.

Not sure about which component failed and put my family and I in significant danger. We had just come to a stop at a traffic light at the end of a highway exit ramp when the car shut off without warning. Completely off. Hazard lights didn’t even work. Nothing worked. Took a minute or two until the vehicle restarted as if nothing had happened. Cars were coming up fast behind us and had to move quickly to get around us. This was late at night so we were hard to spot without any working lights. Thank the Lord no one was injured. I suspect it has something to do with the idle-stop feature. This incident happened within the last 2 hours so it hasn’t been reproduced or confirmed by a service center. Please require Honda into issue a recall for whatever caused this defect.

I have less than 35k miles on my car and I have 5 warning that appeared out of no where. My car has never been in an accident and I take care of it. I searched on YouTube and apparently this is very common issue. It cost $3500 to fix and needs to be with a dealer. The 5 warnings are Issue with car 1) Lane keep problem assist, 2)auto-high beam problem, 3) road departure mitigation system, 4)adaptive cruise control, 5) collision mitigation system, The car is 4 years old and should not have this problem but a lot of people who own the same exact model have tge same issue. Honda needs to do a recall and fix it for free

I just started up the car one morning and had multiple sensor warnings. Brought it to the Honda dealership and told it was an internal sensor camera malfunction and wanted $2000+ to fix it. This honestly should be a recall as I’ve had several other Honda owners complaining about the same thing which is a huge safety concern

I am writing to report a significant safety issue with my 2020 Honda Odyssey. The Front Assembly Assist Monocular Camera (OEM part 36160-THR-C01-M1) has failed, causing the loss of several critical safety features, including auto high beam, lane departure warning, adaptive cruise control, collision mitigation, and Lane Keeping Assist System (LKAS). The local Honda dealership diagnosed the issue as an internal fault in the camera unit. Through research, I have discovered this failure is not an isolated incident. Numerous reports from other Odyssey owners highlight similar issues with the camera leading to the deactivation of these safety features. For example, discussions on the Honda Odyssey Forum and other online platforms describe widespread failures of front-camera-dependent systems, i

After owning this vehicle for a little over a year without issues, I turned on the vehicle and randomly received the following five (5) error messages: Collision Mitigation System Problem, Lane Keeping Assist Problem (LKAS), Adaptive Cruise Control Problem (ACC), Road Departure Mitigation System Problem, and Auto High-Beam Problem. I realized that other Honda Odyssey owners have mentioned receiving the same error messages, especially around my year (2020). The believe all of the error messages are related to the same component - either faulty wiring, camera system, or install issue. The error messages come on every time I turn on the vehicle now. I live in Texas and the first day it occurred was especially hot - it first occurred in the summer months. It is now December with mild weather

The car stalled when stopped at a red traffic light. This happened on 2 occasions, 11-3-23 and 12-9-23. The second time other cars behind us had to go around us while we tried to restart the car which put them at risk of being hit by cars in the other lanes. There was no warning. I took the car in for regular maintenance a few days ago during which the dealership did a multi point inspection but did not discuss this issue. Yesterday I heard about the fuel pump recall and think this might be the same issue. I called the dealership today but they said our car is not under the recall. Our car is available for inspection upon request.

The contact owns a 2020 Honda Odyssey. The contact stated that the back-over prevention camera and cross-traffic monitor were inoperable. The cross-traffic monitor not functioning message was displayed. The vehicle was taken to the local dealer, who confirmed that the vehicle had been repaired under NHTSA Campaign Number: 20V438000 (Back Over Prevention). The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 34,000.

2020 Honda Odyssey EX LKAS, Collision Avoidance, Auto High Beam etc. warning lights to cycle continuously. Had my Honda mechanic check problem and Camera Monocular, forward facing camera causing issues and requires replacement. This is only a 5 year old vehicle with 60,000 miles on it! Honda and many used auto parts want upwards of $850 for camera and then as much as $1500 to replace. This is a serious safety issue. None of this vehicles Safety assist items work without this camera.

In December, out of the blue suddenly had rotating list of warning on dash panel (Lane Keeping Assist problem, Collision mitigation system, departure mitigation system problem, auto high-beam problem, Adaptive cruise control problem) plus Brake Warning system light is on constantly and brake hold not working. At first this was intermittent but now on constantly when starting and driving car. Only 55k miles on my Odyssey. Dealer said he had 3 of these in the last three months. Said it was Multi Purpose front camera failure. Cost over $1500. Since huge safety issue putting not only my family but other cars/people at risk, we are paying to repair, however we just found hundreds of people complaining about this same issue. This should be a Honda Recall. We did nothing wrong to cause this safet

The tailgate control module has been water damaged and needed to be replaced twice. My local Honda dealership was unable to correct the issue and stated that it is due to a water leak in the frame of the vehicle/tailgate. The dealership has identified the tailgate control module as the cause of the electrical issues causing the battery to die, and advanced safety features to malfunction. Warning lights came on for break system problem, lane departure mitigation system problem, and many other systems all caused by the tailgate control module being water damaged from a leak in the frame.

Multi-Purpose camera has failed according to Honda dealership. No safety features work in the car. You pay for the car to have these features and then they fail after only 3 years? Have been dealing with this issue for almost 2 years now. Honda wants $1,800 for the new camera. This is a safety issue that Honda should be responsible for fixing. No adaptive cruise control, no lane keeping assist, no auto headlights, no collision mitigation, no blind spot alarms.

When pulling into a parking space this morning and applying the brakes, the brake pedal did not engage. Pedal went to the floor with no resistance while making a grinding/slipping sound. I was going straight, less than 5 MPH. I released the brake and reapplied quickly (pumped the brakes) before brakes finally engaged. This caused me to come very close, almost hitting the parked car in front of me in the parking lot. I checked the brake fluid reservoir was full and there was no apparent fluid on the ground beneath my car.

While driving on highway, 3 hours away from home, all of a sudden van slowed down and jerking and shaking with loud grinding movement sound from the van started. No warning sign displayed on the dashboard display screen and no warning alert either. Luckily got out of the exit and parked the van. Van was not going beyond first gear and jerking and shaking and making loud grinding sound. Van was not drivable safely. Towed to the local Honda dealership which was 30 miles away. Dealership checked the Van and diagnosed that the 10 speed Automatic transmission has failed and need a new transmission now. There is no warning sign or error on the dashboard display and any warning alert even after this incident happened. I am very disappointed that such an expensive van has no good warning sing

Upon acceleration from a stop, transmission lags to the point of car not moving. It happens when pulling out into traffic, making a turn or pulling away from a light. Have taken to dealer twice to report..now have 7000 miles on car..dealer says its normal..there is nothing wrong with the car..its the way the transmission works.

The airbag deployed unexpectedly while driving without a collision. The vehicle became unsafe to operate, and I sustained an injury. This happened last night so nothing has been inspected yet.

The contact owns a 2020 Honda Odyssey. The contact stated that the vehicle was leaking water from the roof seam near the driver’s side rear of the vehicle. The leak caused water to form a puddle in the trunk tray compartment of the vehicle. The contact had taken the vehicle to the dealer who resealed the roof seam. The manufacturer was made aware of the failure. The approximate failure mileage was 23,900.
