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.

The contact owns a 2024 Honda Odyssey. The contact stated that while at a stoplight, the accelerator pedal was depressed and the vehicle stalled. The contact stated that the vehicle was taken to three dealers a total of five times. The contact stated that the alternator and the battery were replaced. The failure recurred. The contact stated that the battery failed to recharge. The failure mileage was approximately 300.
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.
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.
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The Auto Idle feature has caused my car to stall multiple times. This is extremely dangerous because it always happens when I am in populated areas- sometimes at red lights and another time in stop/go highway traffic. My car is 1.5 years old and this keeps happening more and more frequently. I am very concerned that one of these times I am going to be rear ended because traffic starts to go, I let off the brake to drive and then my car stalls. I then have to turn my vehicle off completely and then back on to get it to not have issues. I do get a warning saying to depress the break and press the start button. Sometimes I get a red battery light on the dash.
The vehicle is experiencing an intermittent but highly dangerous defect involving the factory-installed Auto Idle Stop system. When the vehicle comes to a complete stop at intersections, traffic lights, or in stop-and-go traffic, the Auto Idle Stop system engages as designed and shuts off the engine. However, upon releasing the brake pedal to accelerate, the engine fails to restart automatically. Instead of seamlessly restarting, the vehicle completely stalls in live traffic. The dashboard instruments remain on, but the engine drops completely out of operational mode. To recover propulsion, the driver must shift the vehicle entirely into Park, press the start/stop button to cycle the ignition completely off, and then manually restart the engine. This creates an immediate and severe safety hazard. The sudden, unprompted loss of propulsion leaves the vehicle completely stranded in active intersections and roadway lanes, exposing the occupants to an imminent risk of a rear-end collision. The restart delay forces the driver to perform multiple steps to reset the vehicle while traffic builds around them. The manufacturer is aware of similar systemic restart failures across its V6 engine platforms, which are currently the subject of active the federal safety agency investigations and class-action litigation. However, this issue continues to persist on the newest model years, creating an active road safety risk.
The contact owns a 2018 Honda Odyssey. The contact stated that while driving 60 MPH, the vehicle stalled and lost motive power with several warning lights illuminated. The contact pulled over to the side of the road, shifted the vehicle into park(P), and there was smoke coming from the engine. The vehicle failed to restart after the failure. The vehicle was towed to a service center, where an engine failure was confirmed, and the contact was referred to the dealer for assistance. The vehicle was towed to the dealer, where it was diagnosed and determined that the engine and front axle had failed and needed to be replaced. The manufacturer was made aware of the failure by telephone. The failure mileage was approximately 117,000.
Over the course of 3 days, cruise control and lane assist systems would shut off and messages would display about adaptive cruise control, lane keep assist, lane departure warning, and collision avoidance system not working. Sometimes a transmission problem message would also become active. Sometimes the messages would be present at startup but other times the systems would show up green on the display and then the systems would shut off while driving causing the vehicle to suddenly slow down in highway traffic. The root issue seems to be a broken or malfunctioning multipurpose camera for the driver assist system. The camera has not been replaced yet to verify but related codes are active based on a code scanner and symptoms match what is expected for the camera failure. The vehicle is 6 years old with 99,400 miles at the first occurrence of the issue and does not have any windshield damage or signs of water leaking that would contribute to a failure. My primary concern is that the software completely disables cruise control when the camera for adaptive cruise and lane keep assist fails causing the vehicle to suddenly slow down rather than allow normal cruise control to continue operating and display the warning messages.
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.
