Mercedes-Benz is recalling 499 model-year 2012 versions of the E-Class, specifically E350 and E550 coupes, due to problems with the curtain airbag, according to the National Highway Traffic Safety Administration.
Faulty stitching of the passenger-side curtain airbag could prohibit it from deploying in an accident, increasing the risk of injury. The affected vehicles were manufactured from April 2 through April 29, 2012; can check your vehicle's build date on a sticker on the driver-side doorjamb.
Mercedes-Benz will notify owners next month, and dealers will replace the airbag for free. Owners can call Mercedes-Benz at 800-367-6372 or NHTSA's vehicle safety hotline at 888-327-4236 for more info.
