Reliability indicates how models have performed in the past, providing the basis for predicting
how the vehicles will hold up in the year ahead. These charts provide the most comprehensive
reliability information available to consumers. Based on information received from our latest
subscriber survey for over 300,000 vehicles, our reliability history charts give
you a rundown on how 2000 through 2024 vehicles are holding up in 20
potential trouble spots, ranging from the engine, transmission, electric motor, EV charging, and
brakes to power equipment and the electrical accessories.
NA indicates that we did not receive a large enough sample size to provide
data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Summary:
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2005-2008 Audi A4 Sedan, A4 Avant, S4 Avant and S4 Sedan, 2007-2008 RS4 Sedan, 2004 RS4 Cabriolet, 2007-2009 A4 Cabriolet and S4 Cabriolet, 2005-2011 A6 Sedan, 2006-2011 A6 Avant, and 2007-2011 S6 Sedan vehicles. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
What should you do:
Audi has notified owners, and dealers will replace the passenger frontal air bag with an alternate remedy part, free of charge. The recall began June 29, 2018. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69R7. Note: This recall supersedes recalls 16V382, 17V032 and 18V004 and includes vehicles that may have had their air bag previously replaced under one of those campaigns.
For more information:
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
