“Yet another beautiful Audi 3.0tfsi with the rocker arm failure … how is there not a class action lawsuit already ? I have a knock in my valve train and I just bought this car two days ago …. Audi should be liable to fix this because I didn’t know nothing about this and with a quick search it’s alike a epidemic of the same problem..”

“ON THREE SEPARATE OCCASIONS, THE VEHICLE DID NOT STOP WHEN THE BRAKE PEDAL WAS PUSHED AT HIGHWAY DRIVING SPEEDS. THIS DOES NOT HAPPEN ALL THE TIME. CAR HAS BEEN TOWED TO AUDI DEALERSHIP TWICE, YET THEY FIND NOTHING WRONG WITH THE VEHICLE BECAUSE THE DIAGNOSTIC TESTS THAT THEY ARE RUNNING RELY ON THE COMPUTER, WHICH IS DEFECTIVE TO BEGIN WITH AND NOT RECORDING THE NECESSARY FAILURE (CODES) FOR WHEN THE BRAKES FAIL ON THE VEHICLE. WE HAVE NO CHOICE BUT TO CONTINUE DRIVING THE PER AUDI DEALERSHIP (OPEN ROAD / AUDI MANHATTAN) UNTIL LEASE END.”

I BROUGHT THIS ISSUE UP MY LOCAL AUDI DEALERSHIP AND THEY HAVE ACTED AS IF THEY WERE TOTALLY UNAWARE OF THIS ISSUE. ALSO I KEEP GETTING LOW PRESSURE IN MY FROM RIGHT TIRE, THIS KEEPS ME FROM BEING ABLE TO DRIVE LONG DISTANCES AS I AM MILITARY STATIONED IN AN ISOLATED AREA. *TR”
