My 2024 Honda Odyssey has repeatedly failed to restart after the Auto Idle Stop system shuts the engine off while stopped at a red light or in traffic. Normally, the engine should automatically restart when I release the brake, but on several occasions the vehicle completely shut down and I had to manually restart it. During one incident, the vehicle would not restart for approximately 1–2 minutes despite repeated attempts. This left the vehicle disabled in traffic and created a serious safety concern. The problem has occurred multiple times.
NHTSA complaint #11764011 — an unverified report by a vehicle owner.
The vehicle experiences a sudden and complete engine stall while at a complete stop in traffic (such as a red light) due to a failure of the Auto Idle Stop (AIS) system. The engine shuts down smoothly as intended by the fuel-saving feature, but fails to restart when the brake pedal is released or the accelerator is pressed. The vehicle drops into a total shutdown state, requiring the driver to fully shift into Park, switch the ignition completely off, and manually press the Start button to restart the engine. No warning lights, error codes, or dashboard messages appear before, during, or after the failure. This creates a severe safety hazard by leaving the vehicle unexpectedly stranded and unresponsive in active intersections.
NHTSA complaint #11764114 — an unverified report by a vehicle owner.
The Auto Idle Stop system intermittently fails to restart the engine after the system shuts the engine off while the vehicle is stopped. When this happens, the vehicle remains disabled and I have to completely restart the vehicle before I can continue driving. This has happened twice while stopped in highway traffic. On both occasions, traffic began moving while my vehicle failed to restart, creating an immediate crash risk and nearly resulting in collisions from vehicles behind me. The problem is intermittent. The vehicle has previously been brought to a Honda dealership for this concern, but the failure continues. I have contacted the dealership again and have also contacted the manufacturer regarding the issue. There were no consistent warning signs before the failure. The problem occurs after the Auto Idle Stop system activates. Because the vehicle may fail to restart unexpectedly in active traffic, I am concerned that the condition presents a serious safety risk to the occupants of the vehicle and surrounding motorists. The vehicle is available for inspection upon request. This condition appears consistent with NHTSA Engineering Analysis EA25-004 involving Auto Idle Stop no-restart complaints on Honda Odyssey vehicles.

The van got stuck in park after backing out of a parking lot. Changed to drive but gear shift back to park. Have to restarted the car twice. People were honking nonstop. This is not safe.

My AIS system kicked in causing the engine to shut off. Unfortunately, the engine did not restart. I was unable to start my car or even shift it to neutral for a helpful bystander to help me push my car off of the road. I was blocking traffic on a busy road and I am very fortunate that I was not rear ended. Eventually, after about half an hour, was able to get the car restarted (even then, lots of “clicking” and hesitation with starting). I then drove the vehicle home. I took it to Honda and they made me aware today that they were unable to get the car to repeat this problem, nothing was wrong, I could pick it up and let them know if it happened again.

My 2025 Odyssey stalls. The engine will turn off when I am stopped and will take at least 2 retries to get the engine to turn over. Once I was at a stop light on an interstate off ramp when it stalled. Once I was at a stop sign when it stalled. Twice I have been unable to start it at a store. I will settle the brake & push the start button & nothing will happen. I will try again. I have to take my foot fully off the brake, wait a few seconds, & try the steps again. It eventually starts, but I'm afraid that someone will hit me and hurt my children or myself as I'm a sitting duck.

My vehicle has failed to restart numerous times at stoplights with the auto start engaged. It also failed once when it was disengaged. It also stalls to start on initial start quite often. Even when it is disengaged, upon stopping my vehicle makes a type of quiver in the engine that sounds like a stall or like it is about to cut off. It usually evens out after 5-10 seconds. I had people drive around me, in heavy traffic, after a major fail at a red light. I had an aggressive drive pass around me quickly at another incident at a smaller redlight intersection. I have had it cut off, with my family, over 50mls away from home. A dealership replaced my battery that was under warranty. I was told there were no other issues and to keep my auto start disengaged while driving. I'm not sure that is my safest option at this point. I am extremely concerned it will happen at an intersection and I will roll into traffic with my family.
NHTSA complaint #11763899 — an unverified report by a vehicle owner.
My vehicle has approximately 12,000 miles and on 9/7/26 and 9/11/26, my vehicle would not restart at a light with the auto shut off. I had 4 small children with me on 9/7/26 and had several cars behind me aggressively honking. I could not get the car to restart for several seconds. I was finally able to turn the car completely off and get it to restart. The instance on 9/11/26 was equally as startling. After talking to a friend who has the same Honda Odyssey, she said her van was actually at the dealer with the exact same problem. The Honda dealership told her this is a “known issue” and she is having her starter replaced. I am so upset that Honda has failed to ensure the safety of a van that families rely on. I will be taking our van to the dealer next week.

The contact owns a 2012 Honda Odyssey. The contact stated that while the vehicle was parked or while driving at undisclosed speeds, the clock on the vehicle was flashing, causing a distraction to the driver while driving. The contact stated that the flashing of the clock was controlled by satellite GPS, and the system could not be reset. The dealer was contacted. The failure mileage was approximately 180,000.
NHTSA complaint #11763713 — an unverified report by a vehicle owner.
This vehicle is actively immobilized on private residential property with its central ADAS safety networks and Advanced Driver-Assist networks completely crashed and offline (DTC U3000-49) and active short-to-ground circuit failures (DTC B2035) rendering the passenger sliding doors completely inoperable, creating an immediate entrapment and safety hazard. These progressive component failures cascade directly from severe environmental moisture intrusion inside the rear tailgate enclosure. This exact water migration vector intersects directly with active federal safety campaign NHTSA Recall 26-V-423 (Rearview Camera Failure), which isolates moisture intrusion into the panel housing as the root factory manufacturing defect. A manufacturer franchise location documented active water leakage onto the Power Tailgate Control Unit and heavy corrosion on the wiring connector under a previous Repair Order but performed zero interim moisture sealing, corrosion cleanup, or terminal mitigation, allowing progressive water migration to completely destroy the wiring system harness. Furthermore, American Honda Corporate Case Management explicitly stated on a recorded verbal line that the manufacturer is denying all repair assistance to remedy these cascading safety campaign electrical defects under an active corporate case. The manufacturer is in open default of its statutory federal obligation to remedy a safety recall defect free of charge to the consumer.

Sitting at a light, the auto stop system activated and shut the engine off. When the light turned green, I took my foot off the brake and the engine failed to. Start and the entire electrical system shut off. The card was completely dead. I sat there for several minutes and I was able to restart the car.

On Tuesday, September 8, 2026 while sitting idle at a red light I had my foot on the brake and when the light turned green, I went to push on the gas and the van would not go, nearly causing the car behind me to rear end me because they figured I was going since it was a green light. I turned my hazard lights on, and there was a warning that appeared on the dash but I did not catch what it said in time. When I looked down, the car had put itself in park so I shut the van off and when I turned the van back on, there was a red battery light on the dash and it said “ to continue to drive depress brake pedal and push switch”. The van would not go into gear so I then had to call police (I was blocking a traffic lane) and a tow truck. The van is still at our local Honda dealer where it was purchased and to my knowledge has not been looked at-today is day three of the dealership having possession of the van. Also, on the same day-two stop lights previous to this it had a severe lag from brake to gas.

The failure mileage was approximately 12,000.
NHTSA complaint #11763317 — an unverified report by a vehicle owner.
The idle restart function causes the van to shut off completely when at stop lights in heavy traffic. It does not immediately restart and we have to sit in traffic while folk are honking at us to go. It doesn’t do this every time, but has happened 3 times in the last 3 months.
NHTSA complaint #11763323 — an unverified report by a vehicle owner.
While driving my 2026 Honda Odyssey, I stopped at a red light and the engine shut off through the Auto Idle Stop system. I pressed the Auto Idle Stop OFF button because I wanted the engine running again before proceeding. Instead of restarting the engine, the vehicle completely shut down and became inoperable in traffic. I repeatedly attempted to restart the vehicle, but it remained unresponsive for approximately 20 seconds before it finally restarted. This created a serious safety hazard because I was unable to move the vehicle while positioned in active traffic. This was not normal Auto Idle Stop operation, as the engine should have restarted when I pressed the button. This has happened several times already, where the car will not restart the engine. Requesting that NHTSA investigate possible Auto-Idle Stop/failure-to-restart problems affecting the 2026 Honda Odyssey.

NHTSA complaint #11763084 — an unverified report by a vehicle owner.
The auto idle system shuts off the vehicle completely at a stoplight or intersection and fails to restart when you release the brake. The vehicle is stuck in traffic and doesn’t restart for a few minutes mine had to be jumped started this THIRD time it happened. This created a hazardous safety condition for my family in which kids are always traveling. The dealer has not provided solution. Concerned this can cause a fatality because I can get rear ended.

Front camera failure causing all system errors to not work to include lane keeping assist, adaptive cruise control, lane departure warning, auto high beam.
NHTSA complaint #11762848 — an unverified report by a vehicle owner.
Two intermittent problems began about one year ago at approximately 43,000 miles (current mileage approximately 48,000): 1) Rearview (backup) camera intermittently fails. When shifting into reverse, the display screen goes black or the camera image freezes. This causes a loss of rear visibility while backing up, creating a risk of striking a pedestrian or object behind the vehicle. 2) Audio system intermittently produces loud static and distortion across all audio sources (AM/FM radio, Bluetooth, etc.). This distracts the driver and can mask audible safety alerts. Contacted a Honda dealership regarding recall coverage for these issues; the dealership stated this VIN is not included in the recall. Neither issue has been repaired. The vehicle is available for inspection upon request. These symptoms match NHTSA recall campaign 23V-431 (Honda MOST communication coaxial cable recall — intermittent loss of MOST connection causing rearview camera failure and audio popping/crackling); the dealership stated this VIN is not included in that recall.
