In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the electrical system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
I AM older and I believe the turn signal volume is too low especially due to road noise. This is the only car I drive where it is difficult to hesr the turn signals. Honda cannot fix the volume
1. ) Fuel efficiency is not as reported; it is several mpgs lower under all conditions (highway/city). 2.) safety sensor to alert for pedestrians on sides/front do not work properly. Even service rep at dealership said she has had other reports of it not functioning properly and the sensors/system may need to be 'reset'.
The van will stall after stopping. While turning right, I stop at a stop sign, waiting and when it's safe, go to start to turn, pushing the accelerator and the van will stall. It will take me releasing the accelerator and pushing it again to get it to move again. This is terrifiying.
Our 2018 Honda Odyssey elite has a feature called idle stop. The feature has many criteria that must be met before it will activate. It should just turn off the engine when the criteria have been met in an effort to conserve fuel in lieu of idling.
Headlights: when the van was purchased I discovered several days later that the drivers side headlight was not working. Discovered the lights was not plugged in. December 18 & 27 the anti-theft system disabled. The dealership picked up van and said they repaired. I was told there was a connection that was not securely clipped together.

Additionally, it can prevent the rearview camera image from displaying. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Control and Displays" and 111, "Rearview Mirrors."
