This vehicle will randomly turn these features on and instead of keeping you in your lane pull you off the road, I have had to pull over to turn the vehicle off to get it to turn off

The vehicle will slam on its brakes with nothing around it. This has happened more times than I can count now and has almost caused us to wreck on multiple occasions

I am filing a safety complaint regarding a recurring, severe defect involving the 2025 Honda Odyssey's starter motor and the factory-installed Auto Idle-Stop (idle-stop) system.While driving, the vehicle's Auto Idle-Stop system engaged as designed when coming to a complete stop in traffic. However, when trying to accelerate, the vehicle failed to restart automatically. The engine completely stalled out on an active roadway. Attempts to manually override the system and restart the vehicle using the ignition button failed completely, resulting in an immediate and dangerous loss of propulsion.This defect presents a severe and immediate traffic hazard, as it unexpectedly leaves the vehicle completely disabled and stranded in active lanes of traffic. It strips the driver of the ability to clear the roadway to safety, significantly increasing the risk of a rear-end collision. Multiple occupants, including passengers in the rear seats, were exposed to extreme danger due to this sudden propulsion failure.Despite bringing the vehicle to an authorized Honda dealership, the manufacturer has failed to provide a permanent safety remedy. Also Honda corporate has deny warranty replacement for the starter that’s causing the issue.

My car slammed on the brakes on its own. I was almost rear ended. I was going 45-50 miles an hour. I think it saw a shadow. Previously it has alerted me to brake because of shadows. This is the first time it braked hard on its own.

While driving straight on the highway on a sunny day the car left the lane on it's own, resisted attempts to get it back into the lane, and crashed into the concrete barrier after we swerved around and the car bounced around. Lane keeping assistance and automatic cruise control were active. The lane lines looked perfectly fine. A couple minutes before the accident the car left the lane unexpectedly but we were able to get back into it. Before going on the trip we took the car to the dealer and complained about issues with the car not starting after it shut off while idle at stop lights, or not starting properly, like engaging the parking brake and getting stuck, or starting and rocketing forward even when I only pressed lightly on the gas, leading to loss of traction. They checked the car and said everything looks fine and the tires have 5mm of tread and don't need to be replaced, and they rotated the tires and changed the engine oil. I'm not sure if the issue was with the power steering failing, or traction being lost, or the sensors having an issue causing the car to think the lane was somewhere else and not letting us leave where it thought the lane was. Driver has tons of bruises still and it's been over a week. The other 4 passengers seem ok. The insurance company said the car is totaled and is taking possession of the car. The only warnings lights or messages the car gave us before the accident were about the car having an issue starting back up when all the cars were beeping behind us when the light turned green, and messages about loss of traction, mainly after the engine started back up.

On three separate occasions — May 17, May 20, and May 29, 2026 — the vehicle's Automatic Emergency Braking (AEB) / Collision Mitigation Braking System activated without cause while traveling at highway speed (one of these occasions was on an interstate). On each occasion, no vehicles, pedestrians, or obstructions were present ahead of or around the vehicle. The road was clear. The activation produced a large bright yellow dash notification and the vehicle's brakes activated. Minor children were passengers in the vehicle during these events. The vehicle has an active Florida Lemon Law case with multiple prior documented electrical nonconformities. When I attempted to schedule yet another service appointment to have THIS defect diagnosed, the dealer, who sold me the vehicle, refused to service the vehicle due to the pending lemon law status and directed me to contact Honda Corporate. When I asked the dealer to provide their refusal and the requirement for Corporate authorization in writing, they declined to do so. Honda Corporate has not responded in over 72 hours. Photo and video evidence of other nonconformities is available.

I was driving on the street about 15 miles per hour when the car sensor sensed something in front of my car and stopped automatically when there was nothing in front of me. Almost caused a rear-end accident, luckily, the car behind was able to stop

I see the federal safety agency is aware of the issue with Honda Odyssey AutoStart failing to restart the engine which causes the car to need to be restarted fully while stopped in the middle of traffic. I had this issue many times, my car was serviced with a new battery and 2 months laters its starting again. As an aside one of the front parking sensors will randomly go off which can often cause me to turn off the array. Cleaning didnt help.

With adaptive cruise control engaged and set on any of the four options, my odyssey’s speed slows down for a short time period then speeds up again as I approach the vehicle I intend to pass. This happens when my odyssey is about a car length behind the vehicle I intend to pass. This happens when I’m passing a vehicle on the left or right side. This doesn’t happen every time I pass a vehicle with adaptive cruse control engaged. I had this odyssey in a Honda dealership shop today, February 26, 2026, to hopefully fix this issue. I can’t confirm this but was told by the service agent at the dealership that when this happens, the brake lights will turn on. The fix the dealership service recommended was to set the adaptive cruse control to the minimum following distance setting. I’m going to quote the service technician’s written comment word for word. “Have found this to be a pretty normal symptom of the adaptive cruse system.” I take that as meaning, the service technician has seen this before and it is normal for this vehicle. If this is “normal”, there is a major safety issue with this odyssey. On the way home from the appointment at the dealership service department I had the adaptive cruse control at it’s closest following setting. I passed a vehicle on the left and this issue happened again. When I got home, I called the service manager and told him my odyssey did have the same issue of slowing down even though the adaptive cruse control was set to the closest following distance setting. One more thing to note, the service technician did take my odyssey for a test drive and did experience and there for confirm the above stated issue with the vehicle slowing down. I did speak with the service manager at the Honda dealership about this issue. He was unaware of any other vehicle with this issue and said he would check into it and get back to me. I purchased this odyssey new on January 16, 2025. This problem existed since the day I have owned it.
