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.

2024 honda Odyssey EX-L fails to restart after stop

Filed Oct 26, 2026 · Electrical, Engine · FL

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.

Multiple times since new the van has failed to restart when the auto start/stop has activated. This leaves me in an intersection with a non running car that I need to figure out the right combination of buttons to get it started again. Today it escalated and refused to restart until I shut off the ignition, open the door, closed the door, and then started it. Honda will not do anything if they can not duplicate it. So I am left with a car that is getting more unsafe to drive.

I purchased a used 2024 Honda Odyssey in September 2026 with approximately 12,000 miles. The vehicle intermittently experiences delayed starting and extended cranking when attempting to start the engine. CarMax was aware of the starting concern at the time of purchase. After purchase, CarMax replaced the battery, but the problem persisted. The vehicle was subsequently kept for approximately eight days for further diagnosis, and I was informed that technicians could not reproduce or identify the issue. I am concerned that the intermittent starting problem could worsen and potentially leave my family stranded. I am requesting that the federal safety agency review this complaint for a possible vehicle safety defect.

My 2024 Honda Odyssey repeatedly failed to restart after the automatic idle stop system engaged at traffic lights. On numerous occasions, the engine shut off normally but would not restart when I attempted to resume driving. I had to shift into Park and manually restart the engine before continuing. This happened regularly and created a safety concern because I could become stranded in traffic with my children in the vehicle. I eventually began manually disabling the automatic idle stop feature every time I drove because I was afraid the vehicle would fail to restart. I reported the issue verbally to a Honda dealership employee during a previous service visit and was advised to disable the automatic idle stop feature rather than continue using it. In October 2026, at approximately 21,000 miles, the vehicle displayed a low battery warning. Several days later, it completely failed to start after stopping at a gas station. Three separate jump-start attempts were unsuccessful. The dashboard lights and audio system worked, but the power windows stopped functioning. An authorized Honda dealership diagnosed a completely failed starter. The service advisor stated that the starter failure had also drained the battery. Both components were replaced under the factory warranty. The dealership stated that these repairs should resolve the previous idle stop failures, but the underlying cause of the premature starter failure has not been explained, and I do not yet know whether the problem is fully resolved. I am concerned about the repeated failures to restart in traffic and the complete starter failure at only 21,000 miles. I would like this investigated as a potential vehicle safety defect. I do not know whether the dealership retained the failed components for inspection.

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.
