Summary
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.
Consequence

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Mercedes-Benz been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. Recall repairs are free.
