What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact's client owns a 2020 Honda Accord. The contact stated that while his client was driving at about 45 MPH, the vehicle inadvertently accelerated on his own, drove off the road and drove down in a steep embankment, hit 8-9 fence posts, ramped up over the driveway of the embankment, and crashed into a tree.
From being stopped at a stop light, I then proceeded through the intersection once the light turned green. There was a steel construction road plate on the road just beyond the far side of the intersection and as I approached it at approx 25mph, the emergency braking warning signal on the dash came on and the car…
Car with less than 8000 miles had complete failure of brakes going through a stop sign on a city street (25 miles an hour) and caused a crash that totaled the car. Shortly before the crash the brakes seemed harder to stop at previous stop but still worked.
The engine failed catastrophically. White smoke out of the exhaust at 145,000 miles. Dealer checked out the car and they initially though it was a head gasket failure. After taking the engine head off, it turns out it was a 'structural defect' (verbatim words from the mechanic), which was a divot in the engine block.
When use right turn signal, audio [radio] cuts out. We reported it to the dealer in [xxx], they could not duplicate the problem. Intermittent problem [xxx]- use right turn signal, radio cuts out.
On September 4, 2025, my dealership identified a non-genuine purple quick-splice connector in the driverâs door harness, which they attribute to error codes B1142 (Driverâs Door Lock Knob Switch Circuit), U0199 (Lost Communication with Driverâs Door Module), and U3003-16 (Electric Servo Brake Control Unit Power…
The car acted as if it wasnât getting enough gas and slowed down and was shaking. Giving gas would not help, and it kept slowing down. The check engine light would come on and once I turned off the car and turned it back on, the car acted normal again.
While diving at highway speeds (first at 55mph in may 2025 and then again in July 2025 at 65mph) I got a warning on screen about power loss and a critical failure and that power will be reduced and to stop at the side of the road.
