Recalls

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

Electrical Vehicle recall #14V827000 · 2014 · 84,192 vehicles

What's wrong: In the affected vehicles, the ignition lock actuator May bind, making turning the key difficult or causing the ignition to get stuck in the "start" position.

Why it matters: If stuck in the "start" position, the ignition May suddenly snap back into the "accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags May not deploy, increasing the risk of occupant injury.

The fix: Gm will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The recall began on February 12, 2015.
