2025 Honda Odyssey: check engine light

Filed Oct 12, 2026 · NC

The Honda Odyssey’s Auto Idle Stop/Restart system has repeatedly malfunctioned. When the vehicle comes to a stop and the automatic idle-stop feature engages, the engine fails to restart as intended. This has occurred on multiple occasions, indicating a recurring problem rather than an isolated incident. The exact defective component has not been determined. The vehicle is available for inspection upon request. This malfunction creates a serious safety hazard because the vehicle unexpectedly becomes immobilized in active traffic. When the engine fails to restart, I cannot immediately accelerate or move the vehicle as expected. This creates a risk of rear-end collisions, particularly at busy intersections, stoplights, and other situations where surrounding drivers reasonably expect traffic to move. The unpredictable nature of the failure makes it especially concerning because there is no way to anticipate when the vehicle will fail to restart. The fact that this has happened repeatedly increases my concern for the safety of my passengers, other motorists, and myself. No engine lights when this has occurred. I have to manually restart and it usually lags and cars behind me get mad and then try to zip around me. This makes me feel extremely unsafe- especially since buying this vehicle brand new.

When the vehicle comes to an idle stop and brake is released, the vehicle shuts off and does not kick back on. Only solution in the moment to get the engine to restart is trying to start the car repeatedly until it comes back on. Vehicle has been looked at for this issue but they were unable to replicate the issue. Engine light will sometimes come on when this occurs. Other times the charging system light comes on, as well having multiple warning lights coming on at once. Causes a safety issue when it’s not restarting while in traffic. Issues started a few months after purchase. Took it into the dealer and they determined the throttle body needed to be replaced.

Van has repeatedly stalled during the idle stop restart process when stopped at a stoplight. The van will stall and the dashboard lights up with many symbols. To briefly include, a red exclamation, check engine and battery symbol among others. The car has to be completely shut down and restarted to turn over and function. Obviously an unexpected stalled vehicle in traffic is a significant and potentially injurious or deadly problem. This has been happening periodically since Jan 2026 on a 1 year old van with approximately 12k miles. I have asked the dealer to investigate and they claim no error codes and the battery is ok. I suspect either a starter, brake pedal issues, or software update is needed. I would encourage the federal safety agency to issue a recall or service bulletin as a quick google search reveals this is a common issue on newer Odyssey vans. This vehicle is available for inspection upon request.

This is the fifth time the auto engine shutoff failed to restart after I stopped my car at a stoplight or traffic. This results in potential rear ended accident as one time it stopped in the middle of traffic on the freeway, another time the car behind me at a right turn light that turned from red to green almost rear ended me. No, I brought the car to Honda dealership and they said no problems. But this auto engine shutoff that failed to restart has occurred fifth times. Vehicle has been inspected by dealer and unable to reproduce because they didn’t drive it and step on the brake and have it stopped in middle of traffic. There was an engine warning light that occurred twice but disappeared after 1-2 days before my scheduled dealership appointment. I mention this to dealer. The failure happens suddenly without warning once I step on brake without turning off the auto engine shutoff which I sometimes forget because it is every single time I turn the engine off the auto shutoff would reset. I called Honda America back in January 2026 when I had this problem. I changed my car battery already and so it is not a car battery issue.
