2020 Honda Odyssey Complaints

  • Unknown Or Other, engine 07/02/2026

    Multiple times the engine has totally shut down due to the auto idle stop system power loss. I have had the battery replaced a couple times and had the Honda dealership do the software update and I'm still having issues. This is a major safety issue as the car unexpectedly shuts down and takes a minute or so to get started again causing traffice backups.

  • Forward Collision Avoidance 06/26/2026

    The front-facing Honda Sensing camera in my 2020 Honda Odyssey overheated in a 90deg climate. This triggered multiple dashboard warning lights: Adaptive Cruise Control (ACC) Problem, Lane Keeping Assist System (LKAS) Problem, Road Departure Mitigation (RDM) System Problem, Collision Mitigation Braking System (CMBS) Problem, BRAKE System Problem, and Auto High-Beam Problem. The Honda dealership quoted me $1850 to fix it and they said it was a well-known error. There were NO issues with my car prior to this problem. I keep up with all routine maintenance, oil changes, timing belt and water pump replacements, etc. Not only are these safety features inoperable, but these warning lights are very distracting to the driver, but worse than that- I would be unaware of other system failures since I have so many warnings displayed.

  • Forward Collision Avoidance 06/25/2026

    Front camera default and required replacement totaling $2,400.00 in repair costs. This is a safety issue as the Adaptive Cruise Control, Front Collision Warning, Automatic Emergency Braking, and Lane Departure Warning were all disabled due to the front camera malfunction. This should be a recall by Honda as it seems to be a common mechanical failure in Honda Odysseys from 2018-2022.

  • Forward Collision Avoidance, lane Departure 06/16/2023

    Driving on the road and heard static noise from the infotainment system after an update. Few minutes later the dashboard had multiple warnings and disabling the entire Advanced Driver Assistance Systems (ADAS). The Honda dealer inspected the front camera in the top of the windshield and said it needed to be replaced.

  • Engine 07/01/2026

    While stopped at a traffic light my vehicle went into auto engine idle stop mode. When the light turned green, I removed my foot from the break, but the engine failed to restart. I had to shift the car to park and fully restart the engine.
