Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving on the highway when the speed just dropped from 80 MPH to 40 MPH and brake lights, of course, did not turn on. Because of that, the driver behind me was not warned and almost crashed behind me. It was not only this incident but this happened numerous times and the problem was still not fixed.”
