2005 AUDI S4 CABRIOLET - REAR WINDOW SEPARATING FROM SOFT CONVERTIBLE TOP. TOP APPEARS TO BE SHRINKING AT THE WINDOW EDGES AS WELL. INDEPENDENT CONVERTIBLE TOP REPAIR FACILITY AS WELL AS LOCAL AUDI DEALER CONFIRM THAT THIS IS DUE TO DEFECTIVE ADHESIVE USED IN THE MANUFACTURING PROCESS. AUDI OF AMERICA REFUSES TO REMEDY THIS ISSUE TO DATE. VEHICLE HAS 49,000 MILES ON THE ODOMETER AND HAS BEEN OUT OF FACTORY WARRANTY FOR ONLY A FEW WEEKS. REAR WINDOW WILL ALMOST CERTAINLY COME FULLY LOOSE FROM THE TOP SOON, AND COULD EITHER STRIKE A REAR PASSENGER OR SIMPLY DISLODGE AT HIGHWAY SPEEDS, POTENTIALLY INJURING OR KILLING PERSONS TRAVELING BEHIND THIS VEHICLE. THE POTENTIAL FOR AN EXTREMELY DANGEROUS ACCIDENT IS PRESENT HERE. THIS IS A SERIOUS SAFETY-RELATED DEFECT. A RECALL IS NEEDED HERE TO PREVENT POTENTIAL LOSS OF LIFE. AUDI IS HANDLING THESE TOP PROBLEMS ON A CASE-BY-CASE BASIS, AND IS FIGHTING HARD WITH OWNERS NOT TO PAY AT ALL. AUDI DEALERS ARE QUOTING IN EXCESS OF $6400 TO REPLACE THE TOP, COSTLY ENOUGH TO PREVENT MANY OWNERS FROM SAFELY REPAIRING THE TOP. PER INFORMATION SOURCED FROM AUDIWORLD.COM, MANY OWNERS ARE NOT REPLACING THE TOP DUE TO THE EXORBITANT COST BUT RATHER SIMPLY GLUING OR TAPING THE REAR WINDOW IN PLACE AND HOPING FOR THE BEST. THIS IS AN ISSUE WHICH CLEARLY REQUIRES A RECALL IN THE INTEREST OF PUBLIC SAFETY. *TR

18V427000 · Air Bags:frontal:passenger Side:inflator Module

Jun 22, 2018

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.

Consequence & remedy

Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

Remedy: 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.
