What owners wrote

“Upon startup, LKAS, ACC, FCW and brake lights are illuminated and the corresponding systems are non-functional. This failed with less than 50k miles and the car was ~3 years old. This is making the car less safe to drive because some of the safety systems are non functional. The basic cruise control also does not work.”

“When driving the collision mitigation and brakes come on for no reason. Once when driving down a two lane road with a car coming in the opposite direction in their lane and I was in mine, the car braked. Then once getting on a road nothing coming nor any other vehicle around the vehicle did a hard brake. I just purchased the car last month and it just started happening.”

Should you keep driving it?

This page can't tell you that. 2 of 51 reports involved a crash and 1 people were hurt. 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.
