The problem
Mercedes-Benz is recalling certain model year 2012 E350 and E550 Coupe vehicles, manufactured April 2, 2012, through June 29, 2012. Improper stitching of the right side window curtain air bag may cause it to not deploy as intended in the affected vehicles.
The risk
In the event of an accident necessitating the deployment of the right window curtain air bag, the improper stitching may cause it to deflate more quickly than intended, reducing the protection it may provide, resulting in an increased risk of injury to vehicle occupants.
The fix
Mercedes-Benz will notify owners, and dealers will replace the right side window curtain air bag. The recall began on December 21, 2012. Owners may contact Mercedes-Benz at 1-800-367-6372.
