Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving on the highway and all of a sudden a message on the dashboard said ''engine power is reduced and my engine shut off, brakes were hardly working and I could hardly steer or turn the wheels. My car copmletly lost control and I was lucky there were no cars by me otherwise an accident would have been inevitable. When I went to the dealer they told me they have no answer and they suggested to replace my ignition switch and camshaft sensor to begin with. No guaranty that it'll fix my problem they said. Reading online forums looks like I am not the only one. …”
