Honda Odyssey 2021 has major safety issues – the van starts engine on itself, shuts the engine on itself, tail lights are on when the engine is running, the knob for the lights on the turn signal handle was in off position when the van was observed starting, running and shutting engine on itself – for no reason. In all occasions key fobs were untouched. Once Honda Odyssey was observed with the engine starting and shutting on itself when both of the key fobs were in 10 miles distance from the vehicle. Brought twice to the dealer, cannot fix it. Contacted Honda on 2/17/22 informed about the problem. Called Honda on 2/21/22 to check on the case, was told that will assign a manager to review this safety concern, but it may take two weeks, possibly two month or maybe more, depending how busy they are. 8 days have passed, no response yet from Honda. I am concerned that it may shut the engine on its own while driving.
The 'infotainment" system turned off stating "network connection lost. " the speakers then started making a very loud crackling sound that could not be controlled with the volume button. It was very distracting to the driver--sounded like rocks hitting the windshield. When the infotainment system was off, the blindspot monitor and back-up camera stopped functioning. This has happened several times.
