The campaign affects over a million vehicles worldwide.

Mercedes-Benz will recall 495,290 vehicles from the 2012 to 2018 model years in the United States due to the possibility of inadvertent airbag deployment. This issue is not related to the massive Takata airbag replacement campaign. Instead, this issue stems from insufficient grounding of the steering components, and if static electricity contacts the wrong area, the safety device could activate when it’s not necessary. 

The table below shows the wide array of affected Mercedes-Benz models:

Mercedes also notes that the clock spring in the steering column would need to be broken for the airbag to deploy inadvertently. However, if this piece breaks then there would be a warning message on the instrument cluster.

The automaker began investigating this issue in April 2015 after it received two field reports of inadvertent driver airbag deployment from outside the United States. A third incident came to the company’s attention in late 2016, and further research found two more cases. Daimler created a task force to find the cause of the problem in January 2017. The company found the combination of electrostatic discharge and a broken steering column clock spring as a potential cause in June 2017. Subsequent tests confirmed this hypothesis.

More News From Mercedes:

Mercedes will notify owners by mail. Dealers will then add sufficient grounding to the steering components. The repairs will begin in December 2017.

This recall is part of a campaign affecting over a million vehicles worldwide, according to Deutsche Welle. In addition to the cars in the United States, there are 400,000 of them in need of repair in the United Kingdom and over 100,000 in Germany.

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.

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