Engine fails to restart after Auto Idle Stop - stalled in traffic twice on consecutive days. On XXX around noon, at [XXX], I was first in line in the left-turn lane at a red light, with my [XXX] daughter and another adult passenger aboard. The Auto Idle Stop system shut the engine off. When the green left-turn arrow came on, the engine did not restart and a stall warning appeared on the dash. I had to confirm the van was in Park with the brake applied, turn the vehicle completely off with the start/stop button, and press the start button many times before the engine started. The van sat stalled at the front of the turn lane, blocking traffic, for roughly 60 seconds during the green arrow. The night before, XXX around 11 pm, the same failure happened in the left-turn lane on [XXX]: the engine shut off at the red light under Auto Idle Stop, did not restart when the green arrow came on, and I was stalled in traffic for roughly 60 seconds going through the same restart process. Since about late XXX the engine has also at times restarted roughly after Auto Idle Stop, even when it does not stall. I could not read the exact warning message because I was stalled in live traffic. A dealer has not yet inspected the problem; the vehicle is being taken to a Honda dealer for warranty diagnosis and is available for inspection. I am aware of the federal safety agency investigation EA25004 into restart failures after Auto Idle Stop on Honda vehicles, including 2018-2025 Odysseys.

The auto-stop/start feature in this vehicle, when activated, causes the engine to stall when starting back up. We have had the battery and starter both replaced, and it is still causing an issue. Now, even with the system deactivated, the vehicle will stall, most likely based on the increased wear on the starter. We have noticed that during initial startup, we have to press the ignition button several times before the vehicle actually starts, and often, when it does start, it struggles to start right away.

Sometimes when the car turns off for the auto stop function at something like a stop light or stop sign it stalls when trying to restart. This requires a whole restart with getting back into park and getting the van to start again. It seems to happen most often when the air conditioning is on but not on full blast. I brought it to the dealer once and they couldn’t reproduce the issue or find something wrong. It has happened since that appointment and I am bringing it back. Some lights show up on the dash but i don’t remember which ones as I’m trying to frantically start the van again because I’m typically stalled at a stop light.

When stopped in a lane of travel, the vehicle's Auto Idle Stop system engages. However, when I take my foot off of the brake to begin moving forward, the vehicle stalls while in the lane of travel. I have to turn the vehicle off and back on again to begin moving.

The vehicle came to a complete stop at a stoplight at a busy intersection and the Auto Idle Stop feature engaged. When the brake was released to resume driving, the engine struggled to restart, and then stalled completely in the middle of traffic. The vehicle did not automatically restart upon releasing the brake, and had to be placed into park, turned off completely, and then restarted manually to regain vehicle control. This has happened several times. There have also been instances where the vehicle did not stall completely, but bucked violently when the Auto Idle Stop feature restarted the vehicle.

I am submitting this complaint regarding a serious safety issue with my Honda's Auto Idle Stop/Start system. On multiple occasions, while stopped in traffic or at an intersection, the Auto Idle Stop system has automatically shut off the engine as designed. However, when I release the brake and attempt to proceed, the engine fails to restart. The vehicle becomes stalled and immobilized in the middle of active traffic. I have been stuck at traffic intersections because of this failure, creating a significant safety concern. When the vehicle fails to restart, surrounding traffic expects the vehicle to move when the light changes, while I am unable to accelerate or safely clear the intersection. This creates a risk of a collision, particularly from vehicles approaching from behind.

While stopped at a red light on a busy road my car engine stopped and usually it automatically restarted when I let off the gas but it would not start and the engine would not turn on. The car was stalled and it took multiple attempts to get the engine to restart. This has happened 3 times now. I have had the battery tested and the battery is good and my mechanic believes it is an issue with the starter

The Auto Idle Stop mode has caused my car to stall out at least 10 times since I bought the vehicle in August 2024. Each time it has occurred, it has taken me several minutes to restart the car. I’ve bought my vehicle to Hilton Head Honda in Bluffton, SC two times to have them inspect the vehicle. The only thing they have done is replaced the battery which has not solved the problem.
