2014 Audi Q7 Speed Control & Cruise Problems

CAR SELF ACCELERATED WHILE PARKING INTO A SPACE. IT IS A TDI VERSION WHICH HAD BEEN IN THE SHOP FOR A RECALL MODIFICATION TO COMPUTER THAT SAME WEEK. WHILE PULLING INTO A PARKING SPOT A UNDER 5 MPH THE CAR SUDDENLY ACCELERATED TO A VERY HIGH RPM, JUMPED A CURB AND STRUCK A POLE. 4 PEOPLE EXPERIENCED THE RPM INCREASES (TOW TRUCK DRIVER, AUDI DEALER REP, MY WIFE AND I.

IN JANUARY 2019, WHILE I WAS DRIVING ON CA 110 IN EXCESS OF 60 MPH, THE AUDI Q7 TDI'S GLOW PLUG INDICATOR LIGHT CAME ON, I LOST ACCELERATION AND A FEW MINUTES LATER, MY ENGINE SHUT OFF AND I WAS STUCK IN THE LEFT LANE. I HAD TO CALL 911 AND HAVE CHP STOP ALL TRAFFIC AND PUSH MY CAR TO THE SHOULDER WHILE I AWAITED A TOW TRUCK. AUDI DTLA TOLD ME THAT THE HIGH PRESSURE FUEL PUMP FAILED AND THAT THERE WAS METAL SHRAPNEL IN MY FUEL LINE AND IT ALL HAD TO BE REPLACED. THEY SAID THIS WAS A DIESEL WARRANTY COVERED ISSUE AND WE DID NOT PAY ANY CHARGE. IN JUNE 2019 WHILE DRIVING ON INTERSTATE 10 IN AZ, THE GLOW PLUG LIGHT CAME ON AGAIN AND WE LOST ACCELERATION WHILE DRIVING OVER 60 MPH. WE IMMEDIATELY EXITED THE HIGHWAY AND SHUT OFF THE ENGINE BEFORE THE ENGINE SHUT DOWN ON US, AS IT DID IN JANUARY. WE WAITED AN HOUR IN 105 DEGREE HEAT IN THE MIDDLE OF NOWHERE, UNTIL WE WERE TOWED 80 MILES TO AUDI PEORIA, WHO CLAIM THEY CANNOT IDENTIFY THE PROBLEM. THEY TOLD US TO RIDE IN THE CAR ON TOP OF THE TOW TRUCK. WE BELIEVE THERE IS EITHER AN ONGOING HPFP ISSUE, OR PERHAPS SOMETHING RELATED TO THE DIESEL MODIFICATION, OR THAT THIS PARTICULAR CAR IS A LEMON - 2 BREAKDOWNS IN 5 MONTHS, WITHIN 11,500 MILES. THE SCARIEST PART IS THAT WE WERE DRIVING AT HIGHWAY SPEEDS WITH OUR CHILDREN IN THE CAR WHEN THE CAR LOST ACCELERATION. WE WERE LUCKY THAT WE DID NOT GET HURT OR CAUSE ANY ACCIDENTS, BUT THE AUDI Q7 TDI, WHETHER IT'S JUST THIS VEHICLE OR ALL 2014 Q7 TDIS ARE NOT SAFE. AUDI AMERICA, INC. HAS REFUSED TO REPURCHASE THE CAR OR PROVIDE ANY OTHER ASSISTANCE OR REMEDY. WE REFUSE TO RIDE THE CAR BECAUSE WE ARE SCARED OF ANOTHER INCIDENT. WE HAVE WARRANTIES ON THE CAR, BUT THAT ONLY COVERS REPAIRS, IT DOESN'T PREVENT YOU FROM GETTING KILLED ON THE HIGHWAY WHEN THEY CANNOT IDENTIFY THE PROBLEM WITH THE CAR. NO ONE AT AUDI HAS DIAGNOSED THE JUNE 2019 PROBLEM WE EXPERIENCED.

I BOUGHT MY AUDI Q7 CERTIFIED PRE OWNED FROM AN AUDI DEALERSHIP. SOON AFTER I GOT IT I REALIZED THAT THE ACCELERATOR SOMETIMES GOT STUCK ON A FAST ACCELERATION. I CALLED THE DEALERSHIP AND ASKED THEM TO CHECK FOR A RECALL AND ALSO TOOK IT IN FOR EVALUATION. THEY SAID IT WAS BECAUSE OF THE FLOOR MATS, THE MATS WERE REMOVED/CHANGED. THE PROBLEM STILL EXISTS, AND AS I CHECK FOR RECALLS WITH THAT ISSUE I DON'T SEE ANY IN THE SYSTEM. THE PROBLEM IS POTENTIALLY DANGEROUS, THE FIRST TIME IT HAPPENED I HAD TO REALLY GET THE CAR UNDER CONTROL WITH POWER BRAKING AND OTHER EMERGENCY BRAKING TECHNIQUES, OR I WOULD'VE CRASHED. I JUST HAVE TO REMEMBER NOW TO EXPECT A RUN-A-WAY CAR SITUATION IF I HAVE TO QUICKLY ACCELERATE: FIRST TIME WAS A 0-60 MPH ACCELERATION, OTHER TIMES WAS AN THE HIGHWAY ACCELERATION TO CHANGE LANE OR OVERTAKE ACCELERATION TOOK OVER. I AM ALSO NOT SURE WHAT TO DO ABOUT IT BESIDES GETTING RID OF THE CAR!
