Recalls and investigations

3 recalls on the seat belts cover the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.

Should you keep driving it?

This page can't tell you that. 1 of 43 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.
