2021 Odyssey EXL shuts off completely in traffic stop and go conditions. Happened three times in a 2 week period. Twice in city roads at traffic stop light and once in highway when the cars are in stop / go mode due to heavy traffic. Engine switches off completely and puts itself in "P" mode, all light comes on as if in accessory mode, radio switches off, all doors unlocked. To get going, I had to put foot on brake pedal and start the car again (Engine Start /Stop button).
This issue started in my car at 43K miles. Never had any issue with my before that. But it is scary especially the engine switch off in highway and traffic stop light. Dealer here in Texas said no one had this problem reported so far (as of 26-June-2025) or that he is not aware of solution / fix and will diagnose.
Hope Honda is taking a look at this for permanent fix, as I understand it had happened in Pilot models.
Update from Aug 19, 2025: Honda service center completed the "auto idle stop restart Software update on 30 June 2025. No issue for two weeks after it was done. BUT, it came up again during a traffic stop and go on 21-July-2025 and another one on 4-Aug-2025. Have to take it to dealership what should be done. For now, I am disabling Auto idle switch OFF when I start the vehicle, every time.
