BEING THAT A SAFETY RECALL IS ISSUED CUSTOMER PREFERENCE IS NULL AND VOID BECAUSE SAFETY AND WEALTH HAS NO BEARING IN WHO GETS FIRST DIBS ON AIRBAGS NO AUDI OWNER SHOULD GET PREFERENCE OVER THE OTHER WHETHER IT BE THEY BROUGHT THEIR CAR DIRECTLY FROM THE AUDI DEALERSHIP OR NOT AND THAT THE IMPRESSION I'M GETTING AND BASED ON MY EXPERIENCE NOT ALL CUSTOMERS AND OWNER ARE TREATED EQUALLY

STOPPED ON A HILL AT A STOP LIGHT, WENT TO GO AND CAR LUNGED FORWARD AND DIED. HAD TO IMMEDIATELY APPLY BRAKES, CAR STARTED AGAIN. HAS HAPPENED MULTIPLE TIMES. WE ARE SECOND OWNER, HAVE ONLY HAD THE CAR FOR A YEAR AND FOUND THAT THE TRANSMISSION CONTROL MODULE FOR THIS VEHICLE WAS ALREADY REPLACED AT 49,000 MILES - UNDER WARRANTY TO OTHER OWNER. NOW, AT 130K MILES WE ARE BEING TOLD IT HAS TO BE REPLACED AGAIN. IT IS A DANGER TO DRIVE AS THEY SAID THE TRANSMISSION COULD FAIL OR EVEN THE GEARS COULD SLIP CAUSING DANGER TO THE PASSENGERS. THIS PARTICULAR MODEL OF AUDI TRANSMISSION, KNOWN AS "MULTITRONIC" OR "CVT" HAS NUMEROUS COMPLAINTS AND FAILURES. WE PAID 12K FOR THIS CAR USED AND HAVE A MAJOR MALFUNCTION WITHIN A YEAR. *TR

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.
