2011 Audi S4

AUDI RECENTLY REPLACED MY 2ND THERMOSTAT (1ST WAS 11/2012 AND THE 2ND WAS 11/24/2014), NOT UNDER WARRANTY, AND RETURNED MY CAR TO ME AFTER HOLDING ONTO MY CAR FOR TWO WEEKS. I WAS TOLD THAT MY VEHICLE CHECKED OUT OKAY VIA A DIAGNOSTIC AND MECHANICS REVIEW. I DROVE MY S4 FOR TWO DAYS AND WHILE DRIVING, I RECEIVED AN INDICATOR WARNING THAT READ, GEARBOX MALFUNCTION REVERSE NOT AVAILABLE, YOU CAN STILL DRIVE. I THEN NOTICED THAT THE CAR BEGAN TO VIOLENTLY BUCK WHEN I ACCELERATED. THE CAR SURGED FORWARD WHILE DRIVING IN TRAFFIC WHICH WAS ALARMING TO BOTH MY 10YR OLD DAUGHTER AND I. OTHER CARS HAD TO DRIVE AROUND US AND ONE VEHICLE ALMOST HIT MY CAR IN THE REAR. I CONTINUED TO DRIVE AT A LIMITED SPEED AND IMMEDIATELY, THE TPMS WARNING INDICATOR LIT UP AND THE CAR LOST SPEED. THE CAR WOULD BARELY MOVE AT 10 MPH AND I LIMPED BACK TO A RELATIVES UNDERGROUND PARKING GARAGE. ONCE I PARKED I COULD NOT GET THE CAR TO REVERSE OUT OF THE PARKING SPACE. I CALLED AUDI AND THEY STATED THAT I WOULD HAVE TO TOW THE VEHICLE TO THE NEAREST AUDI SERVICE CENTER. THE VEHICLE WAS TOWED TO AUDI AND I AM WAITING TO HEAR THE RESULTS OF THEIR FINDINGS. I HAVE ALREADY INVESTED OVER $1,750 IN VEHICLE REPAIRS (THERMOSTAT AND REAR BRAKES/ROTORS). I DO NOT WANT TO CONTINUE TO INVEST MONEY INTO THIS VEHICLE PIT. AUDI NEEDS TO RECALL THESE FAULTY PARTS (THERMOSTAT AND MECHATRONIC) AND STAND BEHIND THEIR PRODUCT. I'VE SEEN NUMEROUS COMPLAINTS IN FORUMS AND ON THIS SITE REFERENCING THESE SAME ISSUES. *JS

THERE IS A WELL KNOWN ISSUE WITH THE AUDI 3.OT ENGINE'S PLASTIC THERMOSTAT FAILING! I WAS DRIVING AND THE THERMOSTAT FAILED CAUSING THE ENGINE TEMP TO SKYROCKET TO "H"! I DROVE HOME BECAUSE I WAS CLOSE ENOUGH WITH THE HEATER ON HIGH. THEY FLATBEDED MY CAR ON 9/29/14 FROM MY DRIVEWAY TO THE AUDI DEALERSHIP. DEALERSHIP DETERMINED IT WAS A FAILED THERMOSTAT AND REPLACED IT WITH ANOTHER "PLASTIC THEMOSTAT." THE SECOND THERMOSTAT FAILED 2 DAYS LATER. I JUST TOOK THE CAR TO THE AUDI DEALERSHIP AGAIN THIS MORNING 10/3/14 TO HAVE IT REPLACED AGAIN! THIS PART NEEDS REENGINEERED BECAUSE ITS PLASTIC AND WILL FAIL AT SOME POINT. THANK GOD I WASNT OUT OF STATE WITH MY FAMILY AND IT FAILED BECAUSE I WOULD HAVE BEEN STRANDED! *TR

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

WHILE TRAVELING AT APPROXIMATELY 40 MPH, A WARNING MESSAGE CAME UP DO THE DASHBOARD SAYING "GEARBOX MALFUNCTION, REVERSE GEAR NOT AVAILABLE, YOU CAN STILL DRIVE". AT THE SAME TIME, THE TPMS WARNING INDICATOR CAME ON. THE CAR BEGAN TO LOOSE SPEED AND WOULDN'T RESPOND TO THE THROTTLE, AFTER A FEW SECONDS IT WOULD SURGE FORWARD, AND THEN LOOSE SPEED AGAIN. THIS REPEATED A FEW TIMES, UNTIL I CAME TO A STOP AT AN INTERSECTION. AT THE INTERSECTION, I TURNED OFF THE IGNITION AND RESTARTED THE CAR. THE CAR BEHAVED NORMALLY FOR ABOUT 25 MINUTES OF DRIVING. THEN ON THE FREEWAY AT ABOUT 65 MPH THE PROBLEM RECURRED. I WAS ABLE TO LIMP TO THE NEAREST AUDI DEALERSHIP, WHERE THE CAR IS NOW BEING EVALUATED. I'M VERY CONCERNED ABOUT THIS ISSUE, BECAUSE AT TIMES I WAS UNABLE TO MAINTAIN THE SAME SPEED AS THE FLOW OF TRAFFIC AND AN ACCIDENT COULD HAVE OCCURRED. *TR

THIS ISSUE CONCERNS MY AUDI 2011 S4, A CAR THAT I TOOK DELIVERY ON IN APRIL, 2011. I HAVE HAD NUMEROUS PROBLEMS WITH THE CAR SINCE THE DELIVERY, HOWEVER, IT IS A SAFETY CONCERN THAT HAS CAUSED THIS SPECIFIC FILING. THE PROBLEM SEEMS TO BE WITH THE DSG TRANSMISSION. ON OCCASION, THE CAR WILL STRUGGLE AND "BUCK" IN LOW GEARS AT A VERY SLOW SPEED (OR FROMA COMPLETE STOP) UPON ACCELERATION. THIS DOES NOT HAPPEN OFTEN BUT IT HAS HAPPENED SEVERAL TIMES SINCE TAKING DELIVERY. I HAVE TRIED ADDRESSING THE PROBLEM WITH AUDI CORAL SPRINGS IN THE PAST BUT BECAUSE I CANNOT DUPLICATE THE PROBLEM, THEY ARE UNABLE TO HELP. CONSEQUENTLY, I HAVE NOT BEEN ABLE TO ALWAYS DRIVE THE CAR IN THE MANNER THAT I WOULD LIKE TO. HOWEVER, ON OCTOBER 9, 2012, THE PROBLEM HAPPENED AGAIN, ONLY THIS TIME, IT OCCURRED WHILE ATTEMPTING TO MERGE INTO TRAFFIC. I WAS IN A MERGE LANE, TRAVELING APPROX 3-5 MPH AND WHEN THE OPPORTUNITY AROSE, I ACCELERATED INTO THE TRAFFIC. AT THAT PRECISE MOMENT, THE CAR BUCKED VIOLENTLY (AS IT HAS DONE IN THE PAST) AND I HAD TO LIFT OFF THE THROTTLE TO CORRECT THE ISSUE. LET ME EXPRESS THAT I IN NO WAY AM ATTEMPTING TO CAUSE PROBLEMS FOR AUDI. I AM ONLY CONCERNED FOR MY SAFETY. ITS QUITE CONCEIVABLE THAT WHEN MY CAR HAS THIS TROUBLE WHILE MERGING INTO TRAFFIC THAT I COULD GET HIT FROM BEHIND AS I MUST IMMEDIATELY LIFT OFF THE ACCELERATOR TO RESOLVE THE ISSUE. *TR

I RECENTLY PURCHASED A BRAND NEW 2011 AUDI S4 SEDAN AND HAD A SUSPENSION AND/OR ALIGNMENT ISSUE WHICH CAUSED THE FRONT DRIVER SIDE TIRE BLOW OUT ON THE HIGHWAY, RESULTING IN TEMPORARY LOSS OF CONTROL. I GOT THREE PROFESSIONAL OPINIONS (INCLUDING THAT OF A CERTIFIED AUDI TECHNICIAN) AND ALL AGREED THIS WAS CAUSED BY AN ISSUE WITH THE SUSPENSION, CAUSING THE INSIDE EDGE OF THE TIRE TO WEAR PREMATURELY AND SPLIT OPEN. THIS INSTANCE IS ABNORMAL BECAUSE THE TREAD WAS WELL ABOVE THE TREADWEAR INDICATORS. THIS VEHICLE HAS ALWAYS BEEN SERVICED ACCORDING TO THE FACTORY SPECIFIED SERVICE PLAN FOR MY VEHICLE, BY AUDI CERTIFIED TECHNICIANS. THIS PLAN SPECIFICALLY STATES THAT THE TECHNICIANS ARE SUPPOSED TO INSPECT TIRES FOR WEAR AND DAMAGE AT THE 25 THOUSAND MILE SERVICE (TO ENSURE SAFETY, RELIABILITY, AND VALUE OF THE VEHICLE). HOWEVER, MY SERVICE ADVISORS FAILED TO NOTIFY ME OF THE ABNORMAL TIRE WEAR, AND THE POTENTIAL SAFETY RISK. HAD THIS ISSUE BEEN BROUGHT TO MY ATTENTION, THIS INCIDENT COULD HAVE BEEN AVOIDED. BOTH FRONT TIRES SHOWED THIS ABNORMAL WEAR, SO I HAVE SINCE REPLACED ALL FOUR TIRES. HOWEVER, IF THIS SUSPENSION PROBLEM IS NOT SOLVED, THE NEW TIRES WILL ALSO WEAR ABNORMALLY AND SPLIT OPEN, PUTTING LIVES IN DANGER. THE VEHICLE IS AT THE AUDI DEALER WAITING FOR THE ISSUE TO BE IDENTIFIED AND RESOLVED. *TR
