2025 Honda Odyssey engine problems

Filed Nov 7, 2026 · Electrical, Engine · PA

The vehicle continues to shut off its engine at stops and is unable to restart. This has been occurring at an increased rate since I initially reported it last summer. Warnings come on the dash as it struggles to try to restart. Recently it has started to take a full light cycle to get it to restart. I have to turn the vehicle off and wait some time and try restarting it. I’ve notified the dealership ANTRIM HONDA and their service advisor said it’s a known issue but the starters are on national back order and there’s nothing they can do to help.

Stopped at intersection and engine cut off due to auto-cutoff feature. When foot was released form brake, the engine failed to restart. It took approximately 30-45 seconds to get the vehicle restarted. Auto engine shutoff feature disabled for remainder of trip with no further issues. We have experienced this in the past as well 2-3 other times.

The Auto Idle Stop (AIS) does not work properly and is unsafe. When auto idle engages at a stop light, it is slow to restart, beeps and flashes the battery symbol, and sometimes fails to restart. On a more recent trip, when sitting on a freeway offramp waiting for the light to change with my entire family in the car, the vehicle completely failed to restart after AIS engaged. We were sitting ducks on the freeway and were having difficulties restarting the van. We had to go into Park, Drive, and press the start engine button several times for anything to happen. This issue has been going on for a few months. The battery has been checked and is in good working order, no issues reported. The last battery check occurred today 11/5/2026. I am going to input the date the vehicle completely failed to start, since that time, I have tried to remember to turn off the AIS feature when driving the vehicle. This is a new car and should not be experiencing this incredibly dangerous situation. 2025, Honda Odyssey Elite

The 2025 Honda Odyssey I purchased has issues where the car will not start after the "Automatic Start/Stop" feature turns on. What that looks like is when I stopped on the freeway in rush hour traffic, or at a long traffic signal (usually with many, many people behind me on a busy road), my car will stall and not turn on. I have to wait, sometimes minutes, for my car to restart. This is a safety issue because it will stall / I will have to restart at very inappropriate times, like in rush hour traffic on the freeway. It has happened multiple times. No warning lights or messages came on, other than when the car had officially stalled. By that point, there is nothing I can do besides wait for a minute or so and restart car.

When auto shut off enables at stop lights, sometimes the car goes into park and seems to turn lff and has an error message. It requires pushing the brake and manually starting the car by hitting the on button. There is risk to a rear end collision since it doesn’t happen until you take your foot off the break to start after stopping so creates risk of a rear collision if cars behind don’t noticed you are stopped. It has happened multiple times and seems to happen even more frequently in eco mode

When the auto idle system is forgotten to be not turned off the van will stall. We have had scary incidents where we have stalled at lights and have to restart the van one or more times to get it to drive. There is also problems with the van starting up in the first place. Sometimes when trying to turn on the van it takes a time or two to get it to turn on.

I purchased a 2025 Odyssey at the end of August and it is failing to restart and that the local dealer is delaying the process due to "system outages”. The idle stop process is causing my car to stall at stoplights and I must sit there and wait to turn it off and back on again to be able to drive causing traffic backups and a safety hazard to myself. I had it looked at, at the dealership and was told that all starters and relays are on back order and the day I had it there, the diagnostic computer system wasn’t working so it was never hooked up and diagnosed with this problem. I had my 2025 Odyssey at the dealership on October 31st, 2026.

The idle/stop function fails frequently at stop lights and stop signs. When it stops the engine it fails to restart and drains the battery. It began occurring very early on with the vehicle I’m guessing around 20,000 miles. I took it to the dealership while it was under warranty and they replaced the battery, and I believe the starter. It seemed to help for awhile but around 40,000 miles it started occurring again. I’ve been lucky to not be rear ended but drivers have had to go around me or sit through a stop light. There are no warning lights. I try to turn off the idle off button every time I start the vehicle. It is very unsafe and no longer under warranty. The dealership seemed like they didn’t know what was causing it last time and they had the van for over a week.

Our 2025 honda odyssey stopped running 4 times when stopped at a signal. Took to Hall Honda in Elizabeth city, they said they couldn't find anything wrong. Advised us to "engage a with a circle icon on dash to disengage the system that controls the start-up when stopped. Odd, 2.2 million honda complaints about this same issue. DANGEROUS! Was in a wreck , hit from behind at stop light due to this problem. Almost 8 thousand dollar bill!

The Auto Idle Stop system shuts the engine off when the vehicle is stopped, but intermittently fails to restart the engine. The engine does not turn on again until the car is restarted manually. This has happened approximately 10 times. The vehicle is left disabled in traffic until it can be restarted manually. The vehicle has not been seen by a dealer for this issue yet.
