My 2020 Honda Odyssey died at a stop light while driving on 5/12/2023. The auto on/off feature caused the van to turn off at a stop light and then there was not enough power in the battery to start the car again. It had to be towed to the Honda dealership where they could not diagnose the issue. They said the alternator was fine and the battery charged up fine. So no root cause found. Then 6/26/2023 — I drove the van for an hour to the airport and back, parked it in the garage (engine off) for about 10 minutes, and the van struggled to start but did on the second attempt. Then on 7/7/2023 — my wife took the van to the store, came back home and parked it in the garage with the engine off. She came back 5 minutes later to leave again and the van wouldnât start. The battery was drained. Now itâs sitting on a trickle charger just so I can take it into the dealer. On 7/10/23 — I had the battery replaced and the Dealer did some sort of warranty work to help and that corrected the issue. UNTIL it died again On 11/27/23, I had to get yet again another battery as the same issues began happening and it was deemed a âbad batteryâ. Throughout 2024 and now into 2025 I continually have the same issues where the vehicle will stutter but still managed to kick back on after an auto shutoff. I have been to the dealer countless times and they continually tell me there isnât anything wrong. Something is happening that causes this — whether is an electrical parasitic drain or something else. I have heard that other vehicles this has happened to but Honda claims nothing. I also had a case opened with Honda on this that never went anywhere — Case #13952151 There is clearly something wrong and not being able to diagnose it is even more frustrating given the issue. If it drains while driving — I CANNOT DO ANYTHING. I canât even put it in Neutral to move it manually because everything is electronic!!
