“unknown defects in some vehicles that could cause sudden and unintended acceleration without driver input Yes, our safety was at risk. The vehicle was clearly not in our control. A police report was generated. The car plowed through the garage no control to brake The damages are being inspected by insurance. There were no waring lights that I could see”
NHTSA complaint #11610317, filed 2024-08“In 2024, 2025, and 2026, I have had 2 incidents in each year where the cruise control is set to 60 to 65 mph and the cruise control then accelerates the car past 100 mph. When this occurs, tapping the break does NOT disengage the cruise control. All 6 times I have had to slam the breaks to a full dead stop while the car tries to accelerate anyway. April 4, 2026 and April 14, 2026 are the most recent occurrences and all occurrences so far for this issue have been during a downhill road incline. …”
NHTSA complaint #11731662, filed 2026-04“There was a SUDDEN and UNINTENDED acceleration without the driver input while braking to park going approximately 1 - 2 MPH. Our safety was at risk. The vehicle was not in our control. A police report was generated. Rather than stopping we crashed into the apartment building causing significant damage to both the apartment and our vehicle. There were no warnings, no automatic braking to avoid the collision, the air bags did not deploy. The total damages are still being determined by the dealer and insurance company.”
