Recall 16V146000

Driver's Frontal Air Bag Deploys Unexpectedly, Engine Stalls

Recall Details

The wiring harnesses for the switch module in the steering column could be routed improperly, resulting in chafing of the wiring and possibly causing the driver's frontal air bag assembly to deploy unexpectedly while driving, or the engine to stall while driving. Dealers will inspect the wiring harnesses and properly reroute them as necessary, replacing damaged harnesses when found free of charge to resolve the concern.

Our Quick Take

Due to a wiring harness issue in the steering column, the driver's frontal air bag may deploy unexpectedly while driving, or the engine may stall unexpectedly while driving. Both concerns could cause loss of vehicle control and increased risk of injury.

They will also check for any other incomplete recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with.
