What owners report

  • Steering wheel weaves side to side at highway speed without any driver input, most noticeable when centered.
  • Electric power steering develops a notchy feel and loses true center, requiring constant correction to hold a straight line.
  • Steering feels loosely connected or 'disconnected' from the wheels over 50 mph, especially with large steering inputs.
  • Vehicle fails to start with key or push button despite Audi service ruling out a battery problem.
  • Transmission jerks or lunges forward unexpectedly at low speed, described as related to a faulty mechatronics unit.
  • Front lower grille design allows road debris through, puncturing the intercooling radiator and causing coolant loss.

    Air bags

    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.

    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.

    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.
