“During 20 degree f, I drove my car with no issues to a retail store, parked it in a parking lot. After shopping, returned to my car & started it up, put in reverse, started backing up, then several malfunction lights lit up on the car's dash & the steering wheel locked all of a sudden. I could not turn the steering wheel. I could only move the car forward & backward & this is all while the car is powered on. I had to have the car towed to the dealership. …”
NHTSA complaint #11171921, filed 2019-01, 70,058 miles“My power steering belt snapped off. Prior to that, my brake pedal was loose enough to move it up and down roughly a 1/4 of an inch with my foot. The only way to engage the cruise control was to hold the brake pedal up with my foot, then in order to keep the cruise control engaged was to keep holding the brake pedal up with my foot because it would sense that the driver slightly tapped the brake pedal to disengage it if I stopped holding it up manually. I had to have the brake pedal bolt tightened. …”
NHTSA complaint #11190493, filed 2019-03, 72,000 miles“First instance: while driving on the highway going 60mph my car powered down, preventing me from controlling the car. The gauges and lights inside the car went dark and MPH went to 0. I lost electrical power and after 1 minute the car is back to normal. Second instance: as I was pulling into a driveway and went over a bump the car lost power and powered down, I naturally pressed the gas before I understood what was wrong, the car powers back up as I'm pressing the gas and caused me to almost hit another car.”
NHTSA complaint #11255221, filed 2019-09, 53,000 miles“I live in a one family house with an attached garage. My wife parked the car,with 1/3 of a tank of gas,in our garage about 6:30 pm on august 17. She thought she had pushed the button to turn off the engine, and exited the car taking the smart key with her. About 9 the next morning, while walking my dog, I felt heat coming from the garage and opened the door. It was very hot to touch. I then touched the car and burned my hand. I called our local fire department and they pulled the car out of the garage. The car was so hot, a cd in the door compartment melted. …”
