2025 Honda Odyssey Complaint Log

. When auto start/stop engages at stoplights and fails to restart radomaly but not always, the vehicle remains stationary and blocks traffic lanes when battery light turns on. This creates hazardous conditions where other vehicles must maneuver around a stalled vehicle in intersections, risking rear-end collisions and traffic disruptions. Dealer was not able to replicate Issue as this, i expeted this becouse happens randon times maybe based on weater or after driving for longer peroids . Dealership's only recommendation was to manually disable auto start/stop every time the vehicle is operated. This is unacceptable for a new vehicle and defeats the purpose of this safety

Van completely shut down while in an intersection and the battery light came on. It was hard to restart. Took it to the dealership and they cannot find the problem.

The moonroof on my 2025 Honda Odyssey spontaneously exploded while I was driving it on [XXX] between New Orleans and Slidell, LA. The date of the incident was [XXX]. I was traveling at about 65 mph, the outside temperature was 93 deg F and the sky was clear. The highway was smooth and there was no construction in the area which would have produced loose pebbles or rocks. The explosion was like an artillery piece had fired overhead. I was lucky to have maintained control of the vehicle and the moonroof sliding cover was closed preventing broken glass from showering down on my wife and me. The next day I brought the car to the dealership (Royal Honda, Metairie, LA)to report the defect and to have the car repaired. I was told by the dealer that the manufacturer does not inspect failures such as this one and that Honda declined to repair the damage under warranty even though the minivan had less that 4,000 miles on it and 3 months old. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2025 Honda Odyssey. The contact stated that after coming to a complete stop, the Auto START/STOP feature engaged, causing the vehicle to idle, the transmission shifted to park(P), and the engine failed to restart independently, and the vehicle turned off unexpectedly. The battery warning light was illuminated. The vehicle was restarted. Additionally, the vehicle made a clanking sound while driving over a bump or while making a turn. The vehicle was taken to the dealer, and it was determined that the battery had low voltage, and the contact was advised to deactivate the Auto START/STOP feature. The vehicle was not repaired. The contact related the failure to NHTSA Action Number: EA25004 (Engine and Engine Cooling). The manufacturer was not made aware of the failure. The failure mileage was approximately 10,000.

Description of the Problem I am filing this complaint regarding a serious safety concern and poor quality repair on my 2025 Honda Odyssey, which I purchased new less than one year ago. 1. Engine Auto Idle Stop / Starter Failure Issue The vehicle suddenly shut down when the “Auto Idle Stop” feature was activated. This incident occurred multiple times, and I was unable to restart the engine until several attempts later. This creates a dangerous situation, especially in traffic or intersections. When I contacted the dealer, they confirmed that the issue is caused by a starter motor failure, and the replacement part will not be available until early November — meaning I must drive for over a month with this feature turned off. Many other owners have reported similar problems online, which strongly suggests a potential defect that should qualify for a safety recall. 2. Water Leak and Poor Quality Repair My vehicle also experienced a water leak from the roof area. The dealer attempted to fix it by simply applying sealing material on the roof molding (see attached photos). The repair looks extremely unprofessional, and I requested them to properly replace or reinstall the roof molding, but they refused. This type of repair is unacceptable for a new vehicle of this class and price. 3. Honda’s Unsatisfactory Response I contacted Honda Customer Service (1-800-999-1009) and spoke directly with a representative. However, I was told that: They cannot extend the warranty. They cannot offer any compensation or goodwill service. They cannot provide me with a record or copy of our phone conversation (even though they recorded it). They will only repair the starter once parts arrive. I explained that I have already spent time, fuel, and lost work hours visiting the dealer multiple times, yet they refused any support. Safety Concern and Requested Action The engine shut-off issue clearly affects vehicle safety and could cause accidents in traffic. I request that NHTSA inv

I am reporting a recurring issue with my 2025 Honda Odyssey, which exhibits difficulty starting the engine. Approximately two months after purchasing the vehicle in Dec 2024, the original battery failed and was replaced under warranty. However, the vehicle continues to experience problems when attempting to start. When I press the start button, the engine hesitates, cranks slowly, or feels as though it nearly fails to start. This issue occurs intermittently, regardless of weather conditions or the duration the vehicle has been parked. No warning lights or error messages have appeared on the dashboard The problem has occurred multiple times, most recently on Friday August 15th 2025, and creates a safety concern, as the vehicle’s unreliable starting could leave me stranded in potentially hazardous situations, such as remote locations or adverse weather. I have not yet had the vehicle inspected by a dealer for this specific issue, but I plan to schedule a service appointment to diagnose the problem. The prior battery replacement suggests potential issues with the electrical system, starter, or related components, possibly linked to the auto start/stop system currently under NHTSA investigation for 2018–2025 Honda Odyssey models. Additionally when driving down the road especially at low speeds the engine hesitates as if it’s not getting enough gasoline. Lastly the AppleCarplay screen and all other associated screens randomly go out. I have been to the dealership 3 times for repairs and they give me the run around saying they don’t notice anything so Honda won’t pay for anything and send me on my way.

On two separate occasions the vehicle’s engine has turned off when stopped as part of the Auto Idle Stop feature and then did not restart when I took my foot off the brake and pushed on the gas pedal. I was stuck in traffic frantically trying to get the van to restart and eventually was able to get it. This is a new van I’ve had less than a year. I took it to the dealer after the first incident and described the problem. They kept it for more than a day troubleshooting and didn’t find a solution. Verbally they recommended using the button that turns off the Auto Idle Stop feature that must be pressed each time the van is started to turn the off the feature. I’ve done that most of the time since, but I happened to forget this week and then it happened a second time where I was unexpectedly stuck in traffic with the engine not coming back on.

The contact owns a 2025 Honda Odyssey. The contact stated that the vehicle had a new feature that, when the vehicle was at an idle stop, the engine would shut off automatically, and while the vehicle was stopped for several seconds. The engine was supposed to restart automatically when the driver released the brake pedal. The contact stated that on two occasions, the engine shut off and failed to restart. The contact was able to restart the vehicle. The vehicle was taken to the dealer; however, no cause for the failure was found. The body control module was replaced; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 10,000.

Three times now since buying my van about 6 months ago brand new, I come to a stop light, the engine turns off, but then it won't come back on when the light turns green. I have had to put my hazards on while I frantically push the start button multiple times. Eventually it will start up but takes 1-2 minutes. I brought it into the dealer the first time and they blamed it on a weak battery. After it happened 2 more times, they are replacing the starter but I'm afraid that's not going to fix it. While I wait, i just have to turn off the idle start/stop button every time I start my van.

Normal speed of 25mph on a clear warm day with no road obstructions when the BRAKE System Indicator (Red) illuminated. I pressed on the brake and had severe resistance and was barely able to stop the car. Two more indicators illuminated. One I believe was the Vehicle Stability Assist and the other I don't recall. The screen flashed "Call your Dealer". The Owners Manual states "Have your vehicle repaired immediately." The vehicle was hauled to Southeast Honda. Codes UO416-680416-F8, U0418-68, U3000-49I. The Brake Booster was replaced. I am concerned that an in-experienced driver traveling at interstate speeds might have a fatal issue.

While driving approximately 40 mph, the vehicles emergency avoidance system activated and applied the brakes very heavily. We were nearly hit by a vehicle behind us, which nearly caused multiple accidents. There was nothing in front of us, and the road was co.pletely clear in front of us.

The auto on/off while idling will randomly fail. The car stalls, all emergency lights turn on and the car won’t start for a few minutes. This has occurred at stop lights and in traffic after coming to a complete stop and the car turns off when idling. The car is only 6 months old. The first occurrence happened at the 3 month mark and has become more persistent. I’ve had my battery checked and that was not an issue.

The contact owns a 2025 Honda Odyssey. The contact stated that after opening the electronic passenger side sliding door, the door failed to electronically close while pressing the close button. The contact exited the vehicle and manually closed the door. The contact stated that the failure was intermittent. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 3,000.

When’s stopping the vehicle it shut off and stall to come back on or cut off completely and when i try to restart the vehicle it take several attempts before coming back on. It happens often if i dont turn off the the auto feature

On two differed occasions the AIS system failed and left my car disabled at an intersection. I was sitting at a traffic light and the car died when I took my foot off the break and attempted to proceed through the intersection. Additionally, I have a faulty seat/seat belt. The seat does not register an occupant or indicates the occupant is not buckled in when they actually have fastened their seat belt.

We get a warning light saying "Adaptive Cruise Control System Problem". Van has 4200 miles and it happens during hot days, usually at lunch time. I took it to dealer "Honda Cars of Rock Hill, SC" but they told me there is no code showing up in the Van. I emailed honda America with video but so far no response. The system just goes crazy, beeping and the cruise control is no responsive to cancel button or anything. We are not even using the adaptive cruise control when this happens. After you drive for a while, it goes away, like nothing happened. But when another hot summer day comes, around lunch time, it goes... it does it pretty much during high temps. never in the evening or night time. here is link to YouTube video I sent to Honda: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On June 14th 2025, I reversed up my driveway, uphill, shifted to neutral to allow the vehicle to roll downhill a bit so I could straighten it out. While rolling forward, the transmission was jammed into park with no warning or interaction from me, causing my head to sling forwards in a whiplash fashion from the abrupt change in inertia. This was both harmful to me, to the transmission, and is a major defect. Engaging a transmission into park while moving is reckless, harmful and extremely dangerous. The failing component is most likely the transmission control unit and is available for inspection upon request, but has not been inspected by anyone other than myself. The problem is reproducible by me.

If the car is standing in sun on a very hot day, upon starting the engine it will start beeping with all these errors blinking and disabling these controls. Once the engine runs for 15,20 minutes and the car cools down, the warnings disappear too.

The Auto Idle Stop system on my 2025 Honda Odyssey fails to restart the engine when the brake pedal is released quickly after a full stop. When this occurs, the vehicle stalls completely in traffic and must be manually restarted by the driver. This has happened multiple times and is reproducible. The failed component is the Auto Idle Stop/engine restart system. The vehicle is available for inspection. My safety and the safety of others has been put at risk multiple times because the vehicle stalled at traffic lights in active traffic, leaving me unable to accelerate through an intersection. The problem has been confirmed by Honda Marysville dealership. The dealer stated they could not repair the issue and advised me to modify my driving behavior as a workaround. No repair was performed. The vehicle has been inspected by the selling dealership. A message appears during the failure telling me to restart the car. The problem first appeared within the first year of ownership on a brand new vehicle with basically zero miles at purchase. The cause appears to be a defect in the Auto Idle Stop restart system that fails under specific braking conditions.

Hand control device for disabled drivers is correctly installed under the stearing wheel and works as intended. However, device has several very sharp right angle and corner points that, in the event of a collision, the sharp (not rounded) areas would severely damage driver's knees.

My 2025 Honda Odyssey has failed multiple times in the middle of the road when coming to a complete stop. Auto idle engages and when I try to press the gas the car malfunctions. I have to turn off the car and turn it back on again for it to start. Also at times the interior of the car will start to smell like gas.

I am an engineer and my respect of the laws of probability makes me a cautious driver. I've had m+y 2025 Honda Odyssey for six months, but only driven it 500 miles since it cannot be trusted. I stopped at a light waiting to safely make a left hand turn. I began my turn with enough time for two vehicles to follow me. After pressing the accelerator the vehicle slowly responded. The stall left me in the intersection, so I accelerated hard to avoid being killed. The sudden acceleration was difficult to control and almost resulted in me going off the road. I've come to learn this resulted from a Honda design decision. They have a feature called "Auto Idle Stop" that is ON BY DEFAULT. I was never informed of this feature and believe this was a reckless, or should we say reckmore, decision. This was clearly a deadly design decision. The USG must fix this. In addition, the USG should charge the engineers, and their management, for reckless endangerment.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the vehicle stalled. The check engine warning light was illuminated. The contact was unable to pull over to the side of the road. The contact turned on the hazard lights. The contact waited to restart the vehicle and after several attempts the vehicle restarted. The contact stated that upon depressing the brake pedal and pushing the Start button, the brake pedal was stiff while the start button made an abnormal beeping sound. The message "Press the Brake Pedal and Push the Start Button," was displayed. The contact was able to continue driving; however, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The failure had occurred four times. The vehicle was taken to the dealer to be diagnosed; however, the cause of the failure could not be determined. The vehicle remained at the dealer undiagnosed and unrepaired. The contact no longer felt safe driving the vehicle and left the vehicle at the dealer. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 18,886.

While driving in a construction zone, the vehicle's lane departure system jerked the wheel and almost made me leave the lane Very dangerous. Same vehicle, the A'C was found not operating and a dealer diagnosis found that the system was overfilled and that an electrical connection was not hooked up from the factory. Same vehicle, body panels are not properly aligned from the sliding door to the passenger side door, gap is almost 1/2 inch.

While driving vehicle, the sunroof exploded. I had to fabric inner aspect closed so glass did not enter the vehicle. My [XXX] was in the 2nd row and would have had glass in her face if I had been driving with the fabric part open. Honda is fixing the sunroof currently but I feel unsafe driving with it now. I was on a side street with no overpass near, no cars around and no other vehicle to throw rocks. It simply exploded.

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.
