Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I was driving on the highway at 70 MPH, the check engine came on and about 5 seconds later, a loud noise came probably from the engine. The car then started jolting back and forth; I hit my head on the steering wheel twice and got almost knocked out. The engine stopped while I was still running at 70 MPH. Most if not all the lights in my dashboard came on then I started slowing down. The seat belt never tightened on me as the car was jolting. I kept the car rolling and got out of a very dangerous situation. …”

“In may 2017, while driving, check engine light came on. Acceleration was extremely reduced in a very dangerous way. Took vehicle to dealer. Dealer diagnosed problem as an oil leak that has been leaking on the wiring harness, which caused wiring/electrical system for entire vehicle to completely fail. Estimated repair is $13,500. The vehicle has 34k miles, and the original factory warranty expired in late february 2017. Had routine oil change at dealer in february, no oil leak detected.

“The engine locked up after blowing the top part of the engine off, fire shot out of the engine and quickly went out like a flam thrower. I was driving on the expressway when the accelerator would not work without any warning I didn’t have any issues with this truck. The car cut off immediately thank God I was able to coast to the side of the expressway because it stopped in the left lane on the expressway I was scared for our lives. The dealership has the truck and they said the engine is locked up. This morning s unacceptable for a car I’ve had for a year.”
