2024 HONDA ODYSSEY Electrical System Problems

I believe something is wrong with the electrical system tied into the infotainment system of the car, which displays the radio, heating, cooling, shows the rear camera controllers, as well as some fo the lighting in the sport L is not fully lit, for example where the shift gears is there a light that goes across the front, mines if red, only 1 side is actively turninig on, but the other side is off, at time the display become unresponsive, meaning no matter what I select nothing is displayed I only get the main screen that shows the FM/AM, CAR PLAY, Andriod Auto, Setting etc, when this happens and when the screen flickers the radio does not turn on, no sound is heard, I can turn on/off the ac, but can control where the air flows, or changing some basic settings, at times the rear camera will not work as...

Automatic Idle Stop function fails. The car idles down while at a stop and then the entire car will shut off and fail to restart. This occurs frequently at stoplights, stop signs, in traffic or any time the vehicle idles down. The car fails to restart right away resulting in multiple attempts to start the engine and poses a danger to occupants in traffic.

The vehicle will shut off at stops after the auto idle stop engages. We have to turn the vehicle back on and press the "off auto idle stop" button to not have this happen. I will enter the last date we noticed this below.

Car doesn't start, has needed to be jumped almost 20 times in a year. Auto start stop has shut the car off in intersections

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. I tried bring the issue up to the dealer when I brought it in for its first service, but the employee was extremely rude/belligerent and stated they would only do an oil change when I asked for help with this safety issue among other things. Will take to another dealer next service interval and try again. No issues known or warning lights on the vehicle prior. The van when it did this, error'd stating failure to restart or...

2015 Honda Odyssey with approx 34000 miles. During auto stop/start events the van intermittently would not restart. This issue was worse during warm weather and occured throughout the summer of 2025. It was also noticed that the van sometimes would experience hard starts when restarting soon after a drive. It appeared to be a heat soak issue with the starter and the starter could not turn over the engine. There were no service lights present during this issue. After it failed to start, you would need to turn the ignition off then back on to attempt to restart. Service was performed at Performance Honda in Fairfield Ohio on 11/21/2025, and although the van passed all tests in regards to battery and starter. Initially the van was not going to be repaired/covered, but the van happened failed to start while in the service bay. The starter assembly was replaced under warranty...

While operating the vehicle, I have experienced repeated problems with the idle stop/start system. Specifically: 1-The engine automatically shuts off at stop signs and stop lights as designed, but at times the vehicle fails to restart immediately when the brake is released or the acceleration is pressed. 2-Multiple occasion while stopped in traffic the vehicle unexpectantly shifted into "Park." 3-For the last 3 weeks the vehicle sometimes hesitates to start on first attempt.

Reference: EA25004 Car fails to restart while warm, and idle stopped. This has happened twice in the last three months. The car will idle stop at an intersection - temperature outside is around 90-93. Air conditioner and other electronics are on in the car, but not on full power. The car will fail to come back on when the foot is taken off the brake. The battery light turns on. Must re-start the car using the push button after several tries. This invariably happens at a very busy intersection. Cars behind you see you take the foot off the brake but the car doesn't move - this is a very dangerous situation. 17,000 miles on odometer Took the car to a dealer a few days later. The dealer says everything tests fine. I ask for a new battery, and they claim they replace it after forcing a test failure. Issue...

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 2024 Honda Odyssey has an idle-stop feature which is hesitating too much and risking stalling at intersections. Honda tried to blame it on the battery but even Honda has tested the battery as fine. The 2025 model has a software fix to disable the idle-stop when the AC is running hard and this would fix the 2024 but they claim to have to fix for the car. This is dangerous to be stalling at major intersections and many Honda and Acura vehicles have had and many still have this problem. Remembering to disable the control every time one starts the car is NOT a fix. Please help get this problem for 2024 Honda Odyssey’s fixed before someone gets injured or worse trying to restart a car when it keeps stalling

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

With the auto cutoff engaged when stopped at a red light, the vehicle shut off on its own. I had to put the vehicle in park and try the push button start a few times before the vehicle turned back on. I had to put my flashers on because the light turned green before I could get it restarted. Someone had to swerve to avoid me. I was almost rear ended because the intersection I was stopped at was near an interstate offramp and the driver did not recognize I was stopped. I took it to a Honda Dealership and they said they could not replicate the problem but that there was a bulletin identifying the issue and that the bulletin had been withdrawn. I was told that it likely meant a recall would be coming in the future. The following message came on when the vehicle turned off: Shift...

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.

On occasion, engine fails to restart on its own from a complete stop at a traffic light or road intersection when the Auto Idle Stop function is engaged. Engine and electronics in vehicle completely shut off, requiring the driver to put the vehicle in park and turn the car on again by pressing the Start button.
