What owners wrote

“Multipurpose camera is defective- broken after only 80,000 miles. No longer functions at all. No automatic emergency braking, no forward collision warning, no lane departure warning, no lane keeping assistance, no adaptive cruise control. Dangerous now without all those computer controlled safety functions. $2400 replacement. I don’t have $2400.”

The vehicle only has 37,000 miles on it and it is only 5 years old.”

Should you keep driving it?

This page can't tell you that. 0 of 117 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
