2013 Audi S4

The defect

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2013-2015 Audi A4 and S4 vehicles manufactured February 16, 2012, to October 21, 2014, and 2013-2015 Audi Allroad vehicles manufactured March 12, 2012, to October 21, 2014. Due to an improper algorithm in the air bag control module, if a crash necessitates deployment of the side air bags, a second impact to the front of the vehicle may not command the front air bags to also deploy.

The risk

If the front air bags do not deploy in the event of a secondary impact to the front of the vehicle, there is an increased risk of occupant injury.

The remedy

Volkswagen will notify owners, and Audi dealers will update the air bag control unit software, free of charge. The recall began on November 14, 2014. Owners may contact Audi customer service at 1-800-822-2834. Volkswagen's number for this recall is 69K5.
