Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving 30 MPH I received a red parking brake error and my car began to be very difficult to steer. I then pulled over and received a yellow pre-safe mode error which illuminated the check engine light, ABS light, parking light. I took it took the dealer and was told it was a right tire sensor. This appears to be an ongoing problem with these cars and it's definitely not safe. This definitely needs to be recalled.”
