2024 Honda Odyssey Electrical system Problems

“On multiple occasions, the idle-stop function engaged at a red light and then either the entire car shut down or the computer froze for a minute or two then restarted. For each incident, we had cars behind us that either nearly hit us when we did not go forward when the light turned green or nearly hit us by aggressively going around us while we restarted the engine.”

“The start stop system has failed to restart at a busy traffic light more than half a dozen different times after a 1 hour drive. Short drives do not bring this issue out. This got me stuck at a light, drivers annoyed honking and confused as I try to get my vehicle to start again. Turning the van completely off and back on again seems to get the van to restart again. …”

“When the idle stop feature is engaged (it is by default), my van will die at stoplights, stop signs, or any extended stop. The van has been to the dealership multiple times, battery has been replaced. Service advisor informed me that this is a frequent and known issue with Odysseys. I’m just hoping for some help and/or guidance to remedy this potentially dangerous situation.”

“For a fourth time this year, the vehicle suddenly loses power while travelling on the freeway. It completely shuts off acceleration for 30-60 seconds and then picks back up by itself. The last two ocassions it happened was between 8:10 am and 8:12 am on August 18,2025. It happened on the freeway again on August 22 at about 8:13 am. I fear for my safety and life driving on the freeway”

“The idle stop system was on while I was driving my car. At the stop light, it activated. When the light turned green and I took my foot off the gas, the car shut off. I had to press the ignition start button several times to get the car to start again.”
