Example complaints

Brakes: “I was driving on a 6 lane rd., nearing an intersection. I was in the middle lane, traffic on both sides of me. When I applied the brakes to stop the car, my brakes failed. I ended up hitting the car in front of me. I was lucky that we were all driving at a very slow speed an I did not have serious injuries, just one week of neck and back pain. The brakes failing happened once before. My daughter was at an intersection with no traffic. The light changed to yellow. When she tried to apply the brakes, they failed and she had to go through the yellow light. …”

NHTSA complaint #11349064, filed 2020-08, 973 miles

Engine: “The engine coolant can leak into the exhaust because air a known design flaw. When the the engine turns on after being in electric mode the coolant pump starts and pushes it out the exhaust causing a sudden over heating of the engine. This causes the car to stall and can be very dangerous at freeway speeds.”

NHTSA complaint #11766142, filed 2026-09

Forward collision avoidance: “I leased the vehicle in 03-2021 and within the first year took the car back to the dealer 3 times for complaint on braking system. The brake pedal would loose pressure and stopping distance would extend further than anticipated. the dealer consistently told me that they could not duplicate the problem. now has gotten to the point that EBP light and HOLD light stay on steady and red Brake light flashes, due to this the smart cruise control and crash avoidance system become inoperable. …”
