2025 HONDA ODYSSEY Complaints

Auto Idle Stop has malfunctioned several times causing me to get stuck at an intersection with warning lights flashing causing me to manually shift to “park” or shut down entirely to get it to restart. I was in the vehicle with my three kids and the light turned green and I could not move in heavy traffic. We took the vehicle into the Honda for service and they replaced my battery and did a full system check and battery reload test. Since replacing the battery, it has happened three times in 2 months. The remote start will not start when I try to get vehicle to start when outside the vehicle.

When stopped, my 2025 Honda Odyssey often fails to restart after the auto-idle stop engages. The engine stops, and fails to restart, and lights flash on the screen. I have to then turn the car all the way off, and on again, a process that can take upwards of 15 seconds. The issue happens daily. It will happen on the highway. Additionally, the button to disable the auto-idle engine stop is unreliable and sometimes doesnt work

This vehicle is a 1 year old (2025) Honda Odyssey with roughly 11,000 miles. On two separate occasions now, the auto start-stop feature has caused the engine to die altogether. On both occasions, the vehicle stopped at a red light in a busy intersection, the auto start-stop feature turned off the engine (intentionally), but when the light turned green and my foot came off the brake and onto the gas pedal, the vehicle died entirely. A number of lights and an error message illuminated on the dash board. From my online searches, it seems as though this is a very common issue. 1. What component or system failed or malfunctioned, and is it available for inspection upon request? Auto start-stop / engine. No not available. 2. How was your safety or the safety of others put at risk? Having your vehicle die at a busy intersection or stop sign is a huge risk. It can cause others to try and swerve around you, or it can cause someone not paying attention to rear end you. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle will be brought to the dealer in the coming days. Unfortunately this is my only vehicle and I cannot afford to lose it for an extended amount of time, therefore I have to prolong inspection and servicing. The issue has happened to me twice, and has happened to countless others online. According to others on the internet, the dealers are typically slow to address this issue, and even when "addressed" the issues seem to continue. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, see #3. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings prior to the engine cutting out altogether. Only a message after the failures. In both cases I do not remember what the messages said because I was scrambling to restart my car in a busy intersection.

The contact owns a 2025 Honda Odyssey. The contact stated that while stopped at a traffic light, the vehicle unexpectedly shut off. An unknown flashing warning light was illuminated, and the vehicle was manually restarted. This failure occurred frequently. The dealer was not notified of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 30,000.

The contact owns a 2025 Honda Odyssey. While the contact’s wife was stopped at a red light, the Auto START/STOP feature engaged, and the engine failed to automatically turn off as designed. The brake pedal was released, and the vehicle completely shut off. The vehicle was restarted, and the vehicle operated normally. The cause of the failure was not yet determined. The manufacturer and local dealer were not yet contacted. The contact was informed of NHTSA Action Number: EA25004 (ENGINE AND ENGINE COOLING). The contact stated that the vehicle had experienced the failure listed in the investigation. The failure mileage was approximately 23,000.

What happened? While driving my 2025 Honda Odyssey, the engine failed to restart during an Auto Idle Stop event at a 4-way stop/intersection. When releasing the brake to take my right-of-way, the engine stalled completely. The vehicle became immobilized, the power steering went heavy/stiff, and the brake pedal became difficult to depress. I had to manually cycle the ignition by shifting to "Park" and pressing the "Start" button multiple times to regain power while traffic was waiting. This has occurred twice. What component or system failed or malfunctioned? The Auto Idle Stop (AIS) system and the Starter/Charging System. A service technician recently documented a "slow crank" during routine maintenance, suggesting the battery is unable to handle the restart load. How was your safety or the safety of others put at risk? The vehicle stalled during a right-of-way transition (green light/4-way stop). This created an immediate risk. The loss of power steering and the stiffened brake pedal could have made the vehicle nearly impossible to maneuver manually on an incline during the failure. Has the problem been reproduced or confirmed? A dealership technician confirmed a "slow crank" symptom during a multi-point inspection, though they could not reproduce an issue. The battery tested good. Were there any warning lamps or symptoms before failure? Yes. A "slow crank" was noted by a technician when attempting to start my vehicle to check my vehicle mileage. During the stall itself, a red exclamation point warning appeared on the dashboard.

Vehicle stalled and shut down in traffic after the Auto Idle Stop function engaged at a red light turning the vehicle off and attempting to turn back on. All warning lights flashed. Vehicle would not turn on until after multiple attempts pressing ignition. This has happened multiple (3-4) times over a few months period. Honda dealership was unable to recreate incident but did identify difficulty with engine starting (i.e. slow crank) when manually turning on ignition; however, diagnostics found no issues.

I see the NHTSA 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.

i bought this van brand new for over $53000 and it has been hesitating to start for months. i had the battery tested and came back good. The van hesitates to start and sometimes i have to redo the push button because it fails to start the first time. Yesterday, 02/23/2026 the van left myself and the kids stranded at walmart. it would not start for anything yet the lights and radio work and acted like it was not the battery. i had to call my husband to come get us. we went back hours later to jump it and it started. something is faulty with the started or electrical system to start it. i have another appointment to test the battery and i know its going to test good because i just had this done a month ago and it still hesitates to start. i am not impressed at all and readying online that i am not the only one having this problem. it needs looked into.
