2020 HONDA ODYSSEY Complaints

Sliding doors sometimes do not close all the way and then reopen automatically. You cannot press the sliding doors to close and walk away. You have to stay to make sure they close because often times it will kick back and reopen. You have to manually help push the sliding door to close. Elite trim has no way to make the doors be able to be closed manually, if needed. Took it to Honda, they said they have never heard of doors not closing and reopening so they could not help me, but I have spoken to quite a few Honda Odyssey owners in parking lots and they all stated that the doors do sometimes not close all the way and return to being fully open. Maybe the motor for the doors isn’t strong enough and depends on vehicle tilt or the temperature outside, but for whatever reason the automatic doors are randomly not fully closing.

Vehicle stopped at red light, idle start/stop stopped engine. At green light, upon pressing on gas engine started, vehicle ready to move, but stalled. This happened a few times. Took it to Honda who said they know about this issue and that the Isle start/stop is not a “perfect” system. Tried to sell me an expensive battery. Huge concern in terms of safety in a vehicle with children and stalling in busy streets.

Vehicle suddenly starts having multiple lights and warnings come up such as road departure mitigation, adaptive cruise problem, collision mitigation, auto high beam, etc. reading online it seems multiple people with honda oddysey are experiencing the same issues.

The blind spot system was a problem when I purchased the car, it spent 15 days in service in the first 30 days of ownership to address the issues. Now, I after another light came on I discovered 9 open recalls on the vehicle that were not disclosed prior to purchase.

While driving the vehicle under normal conditions, multiple advanced driver assistance and safety systems suddenly became unavailable without warning. The systems affected include Automatic Emergency Braking, Forward Collision Warning, Lane Keeping Assistance, and related safety features that rely on the forward-facing camera. The failures occurred at the same time and were indicated by warning messages displayed on the instrument panel. The vehicle was inspected by an authorized dealer, who confirmed a diagnostic trouble code indicating an internal electronic failure of the forward multipurpose camera. The failed component is installed behind the windshield and is available for inspection upon request. The dealer stated that no accident, physical damage, misuse, or external cause was identified. After the camera failure was identified, the vehicle also briefly displayed a transmission system warning message that later cleared on its own. In addition, the center display screen has shown unstable behavior while driving, including unexpected resets and flashing back to the navigation screen. The sudden loss of collision mitigation, lane assistance, and warning systems reduces the vehicle’s ability to assist in avoiding crashes, particularly in emergency situations, and increases safety risk to the driver, passengers, and others on the road.

I own a 2020 Honda Odyssey and I am currently having a safety issue with the power tailgate. Upon inspection by my Honda dealership, my vehicle requires a new power tailgate control unit and floor harness and my roof rail and clips need to be re-sealed and replaced. It was discovered that due to the break in seal the connectors corroded due to a water leak.In April of 2026 I received multiple warning messages on my dashboard. The first was Power tailgate problem and the second was keyless remote problem. At first I noticed my car continuously beeping while driving along with the warning on my dashboard. I attempted to turn the vehicle off to see if it would reset, but it did not. I attempted to open and close my tailgate. I could only open my tailgate with the push button on my dashboard. I had to manually close my tailgate due to my buttons on my car and my key fab failing to work. Next while driving, I could hear the locking mechanism on my tailgate continuously locking and unlocking. Of course this particularly concerned me because I have 3 young children and their safety as well as mine was in danger. It was unclear if my tailgate was going to open while driving. Such an action could potentially cause a serious threat or harm to myself, my family or other vehicles on the road.

Backup camera stopped working for no reason, says camera system failure and is a black screen. Research says this is a recall but my dealership says it is not.

The contact owns a 2020 Honda Odyssey. The contact stated that the vehicle made an abnormal ticking sound while depressing the accelerator pedal, and the engine made a loud sound. There was no warning light illuminated. Upon investigation, the contact related the failure to NHTSA Action Number: PE25008 (Engine). The vehicle was taken to the local dealer, where it was diagnosed and there were metal shavings found in the engine oil. The dealer determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and confirmed that there was no recall or warranty coverage for the repair. The failure mileage was approximately 85,000.

We went to a car wash and that day after the car wash we started getting 6+ error message codes for adaptive cruise control, lane assist, lane departure, blind spot, rear cross traffic, etc. our tech that we took it to says they have seen this happen nation wide on these vehicles

Our Odyssey is equipped with idle stop. Sometimes when idle stop engages, the engine won't start again afterwards. We need to turn the car off completely, and then try again. Usually it turns on after doing so. We try to always turn off the idle stop when we start up the vehicle, but sometimes forget. This hasn't led to an accident yet, but has led to some angry vehicles when we can't move when a traffic light turns green. To be clear, this was not an isolated incident, but happens somewhat regularly if idle stop isn't turned off. Honda dealers have told us they don't have any fix, and have recommended that we could purchase a third party "idlestopper".
