2012 Honda Odyssey Electrical system Problems

“I was driving/exiting a parking garage onto a street into traffic. Suddenly, the panel lights and and cabin lights started flashing and the radio and AC cut off, and immediately after, the car cut off and I coasted, through cars moving at speed, to the side of the road. The car was in motion on a city street. At the Honda dealership they took a few days to contact me, then told me I need to pay $800 for a battery cable before they diagnose any issues with the alternator.”

However, when my motor went bad, I was unable to manually open and close the door. …”

Have tried to videotape problem but traffic has spooked my ability and concern that engine would blow, so loud is the rearing up. …”

“The positive battery cable became disconnected from the battery terminal post while driving at full highway speed (75 MPH)!! This resulted in complete electrical failure. I was able to pull off the road, but the door locks were locked and inoperable. Without power I was unable to unlock the doors or roll down the windows. Without power I had no air conditioning. I was trapped in the car on a hot day. The battery cable mismatch (clamp too big to tighten completely on post) is a known Odyssey problem that has been discussed on online forums. …”
