Mercedes-Benz C 300 Recall 17V627: Driver Airbag May Deploy Unexpectedly, Raising Injury Risk

NHTSA campaign 17V627, reported October 6, 2017, 495,290 vehicles potentially affected.

What this recall means for you

The driver's front airbag may deploy without warning because the steering components may not be properly grounded. If static electricity discharges while the airbag clockspring is broken, the airbag can be triggered unexpectedly.

An unintended airbag deployment can increase the risk of injury and may contribute to a crash, particularly if the driver is caught off guard while operating the vehicle.

Mercedes-Benz USA will notify owners, and authorized dealers will add sufficient grounding to the steering components at no cost to you. Owners may contact Mercedes-Benz USA customer service at 1-877-496-3691, and you can check your VIN for open recalls.
