What owners wrote

“Headlights are so dim because of the plastic cover that is made into the OEM headlight assembly. The plastic apparently had no UV protectant and the plastic has turned dingey yellow and clouded where it's affected the light output from the vehicle”

“The headlights are very poor. Can hardly see at night. They're no better when on high beams.”

Should you keep driving it?

This page can't tell you that. 0 of 83 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.
