The driver's air bag may unexpectedly deploy due to insufficient grounding of the steering components if an electrostatic discharge occurs and the air bag clockspring is broken.

    Consequence: If the driver air bag inadvertently deploys, it can increase the risk of injury and a crash.

    Remedy: MBUSA will notify owners, and dealers will add sufficient grounding to the steering components, free of charge. The recall began in December 6, 2017. Owners may contact MBUSA customer service at 1-877-496-3691.
