Recalls

1 vehicle recall from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Exterior lights Vehicle recall #15V519000 · 2015 · 429,170 vehicles

What's wrong: In the affected vehicles, the headlamp driver module (hdm) May overheat and fail, causing the headlamps and daytime running lights to not illuminate.

Why it matters: Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.

The fix: Gm will notify owners, and dealers will replace the hdm, free of charge. The recall began on May 17, 2016.
