2015 Audi S7 recalls

3 NHTSA recall campaigns list this model year.

  1. NHTSA 22V178000Mar 23, 2022Engine26,093 vehicles

    Engine and engine cooling:engine:gasoline:turbo/supercharger

    Volkswagen Group of America, Inc. (Audi) is recalling certain 2013-2017 A8, S6 Sedan, S7, S8, and 2014-2017 RS7 vehicles. The turbocharger oil supply strainer can become blocked, causing wear to the bearings due to lack of lubrication.

    Risk: Worn bearings can cause the turbine wheel to contact the turbocharger housing or cause the shaft to break, causing an engine stall and increasing the risk of a crash.

    Remedy: Dealers will replace the oil strainer and perform an oil change, free of charge. Owner notification letters were mailed August 4, 2022. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 21H7.

  2. NHTSA 18V370000Jun 4, 2018Airbags139,249 vehicles

    Air bags:sensor:occupant classification

    Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2013-2018 Audi S6 and S7, 2012-2018 A7 and A6 Sedan, and 2014-2018 RS7 vehicles equipped with basic seats (with or without heating). Stress or wear of the body-sensing mat within the front passenger seat may cause the Passenger Occupant Detection System (PODS) control module to malfunction.

    Risk: If the PODS module malfunctions, the front passenger air bag may not deploy properly in the event of a crash, increasing the risk of injury.

    Remedy: Volkswagen will notify owners, and dealers will install a PODS system repair kit, free of charge. The recall began November 29, 2018. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 74D5.

  3. NHTSA 18V096000Feb 7, 2018Other3,543 vehicles

    Equipment:other:labels

    Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2014-2015 Audi S7 and 2016-2018 RS7 vehicles. The tire information label on these vehicles incorrectly lists the combined maximum weight as 1146 lbs/520 kg, when the correct combined maximum weight is actually 992 lbs/450 kg. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 110, "Tire Selection and Rims."

    Risk: If the operator were to load the vehicle based on information on the tire information label, they could overload the vehicle, increasing the risk of a crash.

    Remedy: Audi will notify owners, and dealers will replace the tire information label, free of charge. The recall began on March 9, 2018. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 44N9.
