Recalls (2)

Safety recall repairs are free at the brand’s franchised dealers. Before buying, run the VIN at nhtsa.gov/recalls and make the seller show the work was done.

Engine And Engine Cooling · 22V178000

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.

Fix: 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.

Air Bags · 18V370000

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.

Fix: 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.

Questions to ask the seller

Questions worth asking the seller of this Audi before you buy, drawn from its public record:

  1. NHTSA lists 2 recall campaigns for the 2015 Audi S6. Can you run this car's VIN at nhtsa.gov/recalls and confirm each one shows "Remedy Completed"?
  2. Has this car been in any accident or had any structural, airbag, or flood-related repair? Do you have a clean title and a recent history report (Carfax / AutoCheck)?
  3. How many owners has it had, do you have the maintenance records, and why are you selling it?
  4. Are you open to me having an independent mechanic inspect it before we settle on a price?

The fine print: this verdict is computed from public NHTSA complaint and recall records for the 2015 Audi S6 as a model, not for any individual car. A well-maintained example of an “Avoid” can outlast a neglected “Buy”. Informational only, so always get a professional pre-purchase inspection.
