Vehicle: 2021 Honda Pilot NHTSA Recall: 26V-365 Honda Recall: AOU Recall Status: Incomplete/Unrepaire I am submitting this complaint regarding a serious motor vehicle accident involving my 2021 Honda Pilot. At the time of the accident, my vehicle had an open and unrepaired safety recall, NHTSA Recall 26V-365, Honda Recall AOU. I was driving my Honda Pilot downhill when the vehicle began gaining speed in a manner that felt abnormal and uncontrollable. I attempted to slow and stop the vehicle by applying the brakes, but I was unable to stop the vehicle. Despite my efforts to brake, the vehicle continued moving forward and I ultimately collided with another vehicle, resulting in a multi-vehicle accident involving approximately three to four vehicles. The collision was severe. The front of my Honda Pilot sustained extensive damage and the airbags deployed. The vehicle has not been repaired since the accident and remains in its post-collision condition. After the accident, I checked my VIN through the NHTSA recall system and discovered that my vehicle has an incomplete safety recall, NHTSA Recall 26V-365. The recall concerns corrosion at the rear subframe suspension mounting points, which may result in failure of rear suspension components and adversely affect vehicle handling and control. I am concerned that a mechanical or vehicle safety defect may have contributed to my inability to slow or stop the vehicle. I am not stating that the recall definitively caused the accident because the vehicle has not yet undergone an appropriate mechanical or engineering inspection. However, because my specific VIN has this unrepaired recall and I experienced an apparent loss of braking/control immediately before a serious multi-vehicle collision, I am requesting that NHTSA review this incident as a potential vehicle safety defect. I have photographs documenting the extensive p

ENGINE,FUEL/PROPULSION SYSTEM — Filed 09/19/2026

While driving with my family in my 2021 Pilot on the interstate at 75mph, I felt a shudder while in traffic. Fortunately, I signaled to get over and cars around me responded, because the check engine light flashed on and off and the car shut off. We had enough time to roll to the side of the interstate safely because drivers around me were aware and considerate. The car would not restart so we had to tow it. The Pilot has been evaluated by an independent mechanic who says that a failure in the high pressure fuel pump caused oil to dilute gasoline. A full engine replacement is required. There was no prior warning of this issue. American Honda has been contacted for potential support. Early stage of that, but dealing with them has, so far, been great.

Multiple times, when stopped (i.e., red light) and auto-idle engaged, the car has not come out of auto engine stop, but instead has shifted into neutral upon releasing the brake pedal. Furthermore, the car cannot be put into drive from that state, but instead must be fully turned off, and then restarted, often after a pause, and a cranking challenge. Car has a new battery (8 months old) and weather is mild/warm. This problem is unpredictable, and has happened in busy traffic situations, resulting in both a personal and physical safety issue.

POWER TRAIN,SERVICE BRAKES — Filed 04/17/2026

When the brake is pressed at a light or when idling, the gear shifts automatically to neutral and will not drive. I have to press and hold the power button to restart the car. It is happening more frequently. I have taken it to the dealership several times and they have not been able to replicate it. It also doesn’t give any codes. This is a true safety concern because I have impeded traffic multiple times when it occurs. I tried to add pictures of the invoices that I received from the dealership but was unsuccessful.

Our pilot is experiencing similar issues found online with catastrophic engine failure due to a misfire caused by a knocking rod. Honda so far has not responded to our claim despite it being a known issue around the same time ours was manufactured.

AIR BAGS — Filed 02/03/2026

I am submitting this letter as an official complaint regarding a potential safety defect involving the airbag system in my 2021 Honda Pilot. I was involved in a motor vehicle accident on February 3, 2026 in Atlanta, GA. The collision was a direct frontal impact with another vehicle at approximately 35 mph. The vehicle sustained damage with repair estimates over $8,000. Despite the nature of the crash, the airbags did not deploy. However, post-accident diagnostic information reported by the auto body repair shop indicates that the vehicle’s computer system recorded the airbags as having deployed. This discrepancy raises serious safety concerns, as the system appears to have registered a deployment event that did not physically occur. This could indicate a malfunction in the airbag control module, sensors, wiring, or software. A failure of this kind prevented the proper airbag deployment in a crash where it was needed, posing a significant risk to my safety. To my knowledge, the airbag system had no prior warnings or indicators of malfunction before the accident. Directly following the accident an error appeared on the screen behind the steering wheel stating "Airbag System (SRS) Problem." The vehicle is currently at the body shop and available for inspection.

POWER TRAIN — Filed 01/10/2026

The contact owns a 2021 Honda Pilot. The contact stated that while the engine was idling and with the gear shifter in the park position, the contact reached into the vehicle from the front driver's door, and suddenly the vehicle began to slowly roll backwards. The contact was pushed to the ground, causing the front driver's side wheel to roll over the contact's right leg. The vehicle continued to roll backwards before making a U-turn and then rolling forward down the inclined street and increasing speed. To avoid having the vehicle roll down hill into a crowded street with pedestrians, the front passenger inside the vehicle turned the steering wheel, causing the vehicle to crash into the rear of another parked vehicle. During the incident, the contact suffered an injured right leg and was transported to the hospital. A police report was taken at the scene, and the vehicle was towed away. The both air bags had deployed, and the vehicle was destroyed. The contact indicated that during the incident, the emergency brake was not activated. The cause of the failure was not determined. The manufacturer and local dealer were not notified of the incident. The failure mileage was 20,000.

The side curtain airbags deployed while I was sitting in the passenger's side of the car looking into the glove compartment for about ten minutes with the car being completely off and parked in the driveway. The Ignition was off and there was glitching and clicking sounds seconds before the airbags deployed. This could have happened at any point while driving on the street or the freeway. It could have caused an accident and could have killed me if it happened elsewhere. It could have been the passenger's side airbag that deployed and I could have been seriously injured. This incident happened on a Sunday, so I had the car towed to Honda the following day. Honda's response after investigating: "We contacted American Honda Technical Support. Our American Honda District Rep informed us to have the customer contact her insurance provider for repairs." Aside from this official response, I was told that they investigated what they could and found no reason as to why the airbags would have deployed. I was told I had two options. Pay for repair with them or report it to the insurance. I stated that the release of the vehicle was a liability if I decided to not pay for repairs with Honda. After some dialogue, they helped with a loaner car and did not release the car to me. There were no warning lights or messages on the dash whatsoever. About a month prior to this incident, the car started alarming randomly. The random alarming would stop when disconnecting the hood latch sensor. I took the car in for a diagnosis and Honda reported that the cause of the alarm was the keyless access unit. The car (screen and dash) would still glitch after the hood latch sensor was disconnected. My hope is that Honda & American Honda admit responsibility & provide a solution not only for me but for all Honda Pilot owners that may be in danger. Investigating should be a priority, but even if repairs are done to my vehicle, I no longer feel safe driving a my vehicle.

Car slammed on breaks for no reason. Good thing I was paying attention and was able to keep my vehicle under control. My neck hurt for the rest of the day and is Sore today. Now my cars system says the system isn’t working correctly after my car slammed on the breaks for basically no reason. I know this is an ongoing problem certain Honda models already. I believe every Honda with this system should be recalled.

Car in front of me stopped. My vehicle did not causing a rear end collision. I do not recall the brake warning flashing to alert me to brake. The automatic braking system did not seem to engage. Even though I pressed the brake pedal the vehicle did not seem to want to stop. It reminded me of a vehicle without power brakes. Nor did the wheels lock up or leave any skid marks from hard braking.

While making turn with no acceleration, the acceleration of the vehicle got stuck and the brakes did not respond causing the vehicle to hit a sidewalk and breaking the passenger side suspension and control arm and axel of the vehicle. Airbags deployed. Controlled the vehicle until it stopped completely. When vehicle was completely stopped the passenger side still sounded like that gas pedal was fully pressed when the other tires were not moving.

UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE,AIR BAGS — Filed 10/18/2023

On October 18, 2023, at about 11 am, I was approaching to enter our driveway with my foot on the brake system when all of the sudden the car sped up at a very high speed that I was unable to control. The speed was so forceful that the car crashed unto the house resulting in a lot of damage to our house, all this happened in less than one second. I had a next door neighbor in the car with me and thankfully neither of us was hurt, I like to mention at this point that neither air bag deployed to issue protection to us. Of course the safety of both of us was put at risk. We called the insurance with no luck to send an adjuster to inspect the car and/or damage done to the house, so we had to do everything on our own. The car has not been inspected by a representative of the manufacturer nor the police. I did not see any warning nor messages on the screen until the accident happened that said "Crash has been detected" Since we were left to do everything on our own we called Caliber Collision to haul the car to their location to assess the damage done to the car. As of this writing the car is still in their possession and on Friday we received a call from them to inform us what they have found and we were told that as of that day they were sure that the car is 75% totaled. Of course the damage done to the house and car is nothing compared to the damage that it was done to me, because now every time I drive our rental car and approach the driveway I had in my mind if the car is going to do the same thing.
