2024 HONDA ODYSSEY

ELECTRICAL SYSTEM

For a fourth time this year, the vehicle suddenly loses power while travelling on the freeway. It completely shuts off acceleration for 30-60 seconds and then picks back up by itself. The last two ocassions it happened was between 8:10 am and 8:12 am on August 18,2025. It happened on the freeway again on August 22 at about 8:13 am. I fear for my safety and life driving on the freeway

ENGINE

Vehicle is idling rough. Took to dealership and they said it has an obvious misfire. Over a total of six days they had it and performed diagnostics that were requested by Hondas Tech line. The dealership told me that they were informed by Hondas tech line that is just how that vechile is. I got referred to Hondas corporate and spoke with them. I was then requested to bring the vehicle back to the dealership for further testing. They had it less than 3 hours. And again I was told that the vehicle misfiring is just a characteristic of the vehicle. I’m concerned about my vehicle misfiring and Honda not wanting to fix it. I don’t want to be driving down the road with my family and have an engine failure. Issue has been ongoing for a few weeks

POWER TRAIN

Transmission has hard shifts in lower gears. Causing the car to jump/jerk wich could cause driver to possibly loose control in wet road conditions.

ENGINE

Vehicle will fail to restart after Auto Idle Stop engages at times. Dealership performed reset, but issue continued afterwards . Safety Issue due to delayed acceleration. Has been brought in twice for this issue with no resolution.

ENGINE

With the auto cutoff engaged when stopped at a red light, the vehicle shut off on its own. I had to put the vehicle in park and try the push button start a few times before the vehicle turned back on. I had to put my flashers on because the light turned green before I could get it restarted. Someone had to swerve to avoid me. I was almost rear ended because the intersection I was stopped at was near an interstate offramp and the driver did not recognize I was stopped. I took it to a Honda Dealership and they said they could not replicate the problem but that there was a bulletin identifying the issue and that the bulletin had been withdrawn. I was told that it likely meant a recall would be coming in the future. The following message came on when the vehicle turned off: Shift to park. The red battery dash light was on.

ELECTRICAL SYSTEM

When the idle stop feature is engaged (it is by default), my van will die at stoplights, stop signs, or any extended stop. The van has been to the dealership multiple times, battery has been replaced. Service advisor informed me that this is a frequent and known issue with Odysseys. I’m just hoping for some help and/or guidance to remedy this potentially dangerous situation.

ENGINE

I was stopped at a red light for a long time. The idle on/off feature engaged, turning the engine off as expected. However, the engine would not turn back on; the vehicle completely stalled. It took several attempts to get the vehicle to turn back on. I was on a very busy 5-lane road with my child in the car. This was very dangerous as we were in a middle lane. We would not be able to safely exit the vehicle. I was extremely worried we would be rear-ended.

SEAT BELTS

Subject: Urgent Safety Concern: Driver Side middle Seat Belt Malfunction I am writing to report a serious and distressing incident involving the driver-side middle seat belt in our Honda Odyssey van. While parked, the seat belt became stuck and tightly wrapped around my [XXX] son. Despite trying all possible options, including turning off the engine and shifting to park, we were unable to release the belt. After struggling for 45 minutes, we had no choice but to cut the seat belt in order to free the child. The experience caused significant panic and distress to my child and was extremely dangerous. This raises serious safety concerns. Please let me know immediately: •If this is a known issue or part of a recall. •What steps Honda is taking to address this. •Whether it is safe to use the vehicle until this is resolved. We are extremely concerned and would appreciate your urgent attention to this matter. Sincerely, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

VISIBILITY/WIPER

While driving on a highway in California we heard a bang above our heads followed by a cracking sound. I knew immediately that the sunroof exploded based on reading posts about it in a Facebook Odyssey owners group. Fortunately the interior slider/shade was closed and no glass fell on us. There was nothing above us to fall on the roof. There were no cars on front of us to kick up road debris, nor did we see anything airborne. The road was flat and smooth. The temperature was in the low seventies and had not changed in the previous hour. There is no discernable reason the glass would just shatter. We used duct tape to attempt to hold the glass together to 1) keep it out of the passenger compartment 2) weatherseal the car as precipitation was forecasted. We proceeded on our trip and stopped in Flagstaff, AZ. It was disturbing to find out that we had to purchase the glass from a Honda dealer and have it installed by a commercial auto glass business as the dealer doesn't do glass installation. It is ridiculous that I lost a day of travel to a problem that has been around for over a decade with NHTSA reports and a class action lawsuit about the poor quality of Honda sunroofs.

SERVICE BRAKES

The contact owns a 2024 Honda Odyssey. The contact stated that while driving at 60 MPH, the brake pedal was inadvertently applied without driver input. There was no warning light illuminated. The vehicle was taken to several dealers however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 2,997.

FORWARD COLLISION AVOIDANCE: WARNINGS

I was driving my vehicle and accelerating. My vehicle suddenly braked with no warning while I was driving. I hit my left side of my head as I was not expecting this to happen. I was nearly rear-ended/nearly caused a multi car accident. It was incredibly scary to have the CMBS go off for absolutely no reason. There was no car ahead of me or other reason for it to happen.

ELECTRICAL SYSTEM

On occasion, engine fails to restart on its own from a complete stop at a traffic light or road intersection when the Auto Idle Stop function is engaged. Engine and electronics in vehicle completely shut off, requiring the driver to put the vehicle in park and turn the car on again by pressing the Start button.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

This complaint alleges issues with this vehicle as follows: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2024. 2. Namely, Honda has placed the RADAR behind the large HONDA emblem on the front grille. This causes the radar to give a "RADAR OBSTRUCTED" warning, which disables all Advanced Driver Assistance Systems in the car (Automatic Emergency Braking, Adaptive Cruise Control, Forward Collision Warning). 3. The "RADAR OBSTRUCTED" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the RADAR at the cost of $800 each time since it takes several hours to do (per Dealership). 4. The official Honda Odyssey Forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, i.e., the placement of the radar behind the large, thick plastic H emblem obstructs the radar. 7. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a RECALL that permanently addresses the problem. Thank you for your time and reviewing this systemic issue.
