2025 HONDA ODYSSEY Complaints

On multiple occasions our vehicle has turned off at a stop (auto start/stop) and failed to restart upon pressing the accelerator. It then takes several seconds to be able to restart and get moving.

Idle start stop system was engaged at stop light. When I released the brake the van engine should have restarted - however the van completely died at this point. I had to wait about 10 seconds and then restart the entire car while sitting at the stop light. Very dangerous - the vehicle has also done this when at a stop light but cut off after I started to make a turn - leaving me in a dead vehicle in traffic's way -

Description: Subject: Formal Warranty Claim – Spontaneous Glass Breakage and Request for Immediate Assistance Serious and unexpected failure involving my vehicle, a 2025 Honda Odyssey Elite (VIN: [XXX] ), currently with approximately 26,000 miles. On April 19, 2026, I submitted an initial complaint to Honda concerning what appears to be a spontaneous breakage of the rear side (fixed quarter) glass. The vehicle was parked overnight in driveway when the glass shattered without any known impact, external force, or evidence of vandalism. The fracture pattern is consistent with spontaneous tempered glass failure originating from the edge, which raises concerns of a potential manufacturing defect or internal stress within the material. On April 20, 2026, I presented the vehicle in person at my local Honda dealership for inspection and assistance. To date, no action has been taken, nor has any resolution been provided. This lack of response is unacceptable given the safety implications. Due to safety concerns, the vehicle is currently not in use and remains parked. I am unwilling to operate the vehicle in its present condition out of concern for further damage or risk. As a result, I am experiencing a significant disruption to my daily activities and mobility. Accordingly, I respectfully request the following: 1. Immediate review and approval of this issue under Honda’s warranty as a case of spontaneous glass breakage. 2. Prompt authorization for repair or replacement of the damaged glass at no cost to me. I have photographic documentation available. Sincerely, [XXX] [XXX] [XXX] ?VIN: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is the second time I have taken it to the dealership. When sitting at a stop and the automatic stop and start happens, it acts like it does not want to crank back up. Last time the dealership said it was the battery; they replaced the battery, but that has not fixed the issue. if I am at a stoplight and it does not start back, that is not a good feeling my wife now does not want to drive the van anymore because of the seriousness of this issue as well has having young children in the car. This is a van that was bought brand new and has been in the shop more than it has been driven.

I purchased a new 2025 Honda Odyssey XLE in February 2025 and soon noticed a clunking noise coming from the front suspension whenever I hit bumps. I contacted the dealership, and they scheduled an appointment. After inspecting the vehicle, they told me they could not find anything wrong. However, when I left the dealership, the noise was still there. The issue has since gotten worse. The clunking noise can now be heard when starting the engine, during transmission downshifts, and over even small bumps in the road. It feels like something in the suspension is loose, and I believe it is unsafe to drive. I am requesting that the vehicle be bought back. The dealership where I purchased the vehicle is 380 miles away, and I am currently on military orders, which makes it difficult for me to return to that location.

When Idle start/stop function is engaged and then goes to restart, the engine hesitates or fails to restart all together.

When I am stopped at a stop light or in traffic my auto start fails and kills the electric in my vehicle when I push the pedal to go. This has happened several times and in one instance, almost caused me to be rear ended. It took several attempts to restart the car all while other cars are buzzing past me. It is currently at the Honda dealership for the 4th or 5th time for this same issue. My battery was replaced all ready thinking that was the solution, but it was not. I personally know of two other people having this exact issue with their vans.

The contact owns a 2025 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the idle stop feature turned off. The contact stated that the parking brake unexpectedly engaged, and the vehicle shut off with the message “Idle Stop Not Available” displayed. The contact was able to restart the vehicle. Additionally, shifting the vehicle out of park became difficult, and the contact had to wait an extended period before the vehicle could be restarted. The contact stated the failure would not occur while the idle stop feature was engaged. The vehicle was taken to the dealer, but was not diagnosed or repaired. The dealer informed the contact that the failure could not be duplicated. The contact was advised to return the vehicle if the failure persisted. The vehicle was taken back to the dealer; however, the vehicle was not diagnosed or repaired, and the dealer refused to disengage the idle stop feature. The manufacturer was made aware of the failure. The failure mileage was approximately 23,000.

Multiple times since purchasing the vehicle, the engine fails to restart after the automatic idle stop feature engages at red lights or stop signs. When I release the brake to resume driving, the vehicle attempts to restart but makes a struggling or grinding noise and then stalls completely, similar to a dead battery. The vehicle becomes unresponsive and does not restart immediately. I am forced to turn the car off and attempt to restart it multiple times, often waiting several minutes before the engine turns back on. This has occurred in traffic, creating a safety hazard due to vehicles behind me and my inability to move the car. The issue appears to be related to the automatic idle stop/start system and may involve the starter or battery failing to properly restart the engine.

Engine Shutoff/Idle Stop Failure: The vehicle fails to restart after the automatic idle stop engages in traffic, requiring a manual restart. Electrical System Malfunctions: car dying at stoplights, loss of power, and, in some cases had to restart in "limp mode" where the vehicle is restricted to 1st gear,not very safe on major highways. Reported this to Honda during service on 3-16-26, they didn’t find anything? Has happened 7 times since it was serviced.
