“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.”

“All warning lights came on for Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance.Based on my research, it seems the forward facing camera has failed. The vehicle only has 37,000 miles on it and it is only 5 years old.”

“The camera is faulty and I've brought it in once early on and the dealer said a wire needed to be tightened. It happened again and they said no such loose wire this time. The code says camera needs to be replaced. I don't even have 100k miles on this car and it's going bad. Faulty part and I know this is happening a lot.”

Should you keep driving it?

This page can't tell you that. 0 of 90 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.
