2019 Audi Q8

I purchased a used 2019 Audi Q8 Prestige Plus, with Sportline Pkg on 9/7/21. Car had approx. 18,500 miles. The car attempts to shut off when deaccelerating at any speed below 3000 rpm. There is also a significant throttle delay between the time you push the gas pedal and when the engine responds. To be clear the car is in Dynamic mode and the Start/Stop mode is deactivated. It appears that under certain conditions the car is trying to determine if it should shut down or continue running. The Audi 37M6 update has been performed on my car which was supposed to correct the problem. The Audi Knoxville Shop Foreman drove the car and experienced the problem, contacted Audi Technical Assistance center (case# HS-822562) and was told that the car had the latest software correction. The Shop Foreman wanted to erase the transmission clutch adaptations to see if the car could relearn the shift process but was advised by Audi Technical Assistance not to erase the transmission clutch adaptations and would not allow the Shop Foreman access to the car software in an effort to diagnose the problem. Note: there was a class action lawsuit in May 2020 for this problem that was dismissed because the car manual states the car can experience a delay when restarting from the Start/Stop mode. However, my issue occurs when the Start/Stop system is turned off. There is no continuous throttle response below 3000 rpm with the Start/Stop system turned off. I was given a 2021 Q7 with a 2.0 as a loaner car while my Q8 was in service and I did not experience any of the issues I have with my Q8. I was advised by my dealership to also write a letter to Audi USA as the dealership acknowledges there is a major problem and they want to try fix the issue but will not be given access to the car software to troubleshoot the issue. This is a dangerous problem.

The auto start/stop feature of this vehicle is horrible, on several occasions I've almost gotten into an accident turning at an intersection. The engine loses power for 2-3 seconds despite pushing the gas pedal all the way down. I've also scared pedestrians at cross walks on several occasions when the vehicle is at a full stop but then suddenly lunges forward at them. The sensors on this vehicle are also very faulty. The ones that are supposed to open the rear hatch do not work despite me waving my feet and hands under them for several seconds at a time. The key fob also doesn't open the rear hatch like it's supposed to. And the sensors to detect objects around the perimeter go off all the time without any apparent reason. I've had the vehicle in for multiple service visits and none of these issues have been resolved.

I'M VERY UPSET WITH NHTSA AND AUDI. I SUBMITTED A COMPLAINT WITH NHTSA ON 10/22/20 AND THE COMPLAINT NUMBER IS 11365744. AGAIN AS STATED IN MY COMPLAINT THIS IS AN ACTUAL SAFETY ISSUE. I THEN TOOK THE VEHICLE INTO THE DEALERSHIP FOR THEM TO LOOK AT THE PROBLEM. WELL IT TURNS OUT THAT THE DEALERSHIP'S SERVICE DEPARTMENT HAS HAD A NUMBER OF COMPLAINTS JUST LIKE MINE. IT ALSO TURNS OUT THAT AUDI HAS A FIX FOR THE PROBLEM. THE FIX IS A SOFTWARE UPDATE 37M6. I'M GLAD THE ISSUE HAS BEEN FIXED ON MY VEHICLE BUT THE REAL ISSUE IS THAT NHTSA AND AUDI ARE AWARE OF THIS FIX BUT BOTH OF THESE ENTITIES ARE NOT REQUIRING THE FIX TO BE MADE VIA A GOV'T ISSUED RECALL. AUDI CALLS THIS FIX A "CAMPAIGN". AUDI IS AVOIDING THE STANDARD PRACTICES OF NHTSA BY REFERRING TO THIS PROBLEM AND FIX AS A CAMPAIGN WHICH IS OUTSIDE OF THE NORMAL TECHNICAL SERVICE BULLETIN AND SAFETY RECALL PROCESS. HAS NO ONE AT NHTSA OR AUDI LEARNED THE LESSONS OF THE GM DEBACLE WITH THE IGNITION SWITCH. THIS COVER UP BY NHTSA/DOT AND AUDI IS A COMPLETE AN UTTER DISGRACE. TO ALLOW AUDI TO OPERATE OUTSIDE OF THE NHTSA SYSTEM IS A COMPLETE FAILURE. NHTSA NEEDS TO MANDATE AUDI ISSUE A SAFETY RECALL ASAP!

OUR A8 HAS ISSUES WITH LAG TIME WHEN ACCELERATING FROM A STOP OR A SLOW SPEED OF LESS THEN 10 MPH. THE VEHICLE SEEMS TO STOP RUNNING PRIOR TO A FULL STOP AND IF THE ACCELERATOR IS DEPRESSED NOTHING HAPPENS FOR ABOUT 5 SECONDS. THIS IS EXTREMELY DANGEROUS AND LEAVES US AT RISK OF BEING INJURED OR KILLED. THIS ISSUE STARTED JUST A FEW MONTHS AFTER PURCHASE AND HAS GOTTEN CONTINUALLY WORSE. WE HAVE ALSO ENCOUNTERED THIS ISSUE EVEN AFTER A FULL STOP AND THEN TRYING TO ACCELERATE FROM A FULL STOP. IT HAS EVEN HAPPENED WHEN DRIVING ON AN INTERSTATE HIGHWAY WHEN TRYING TO PASS ANOTHER VEHICLE. THE DELAY IN ACCELERATION IS VERY DISCONCERTING AND DANGEROUS TO SAY THE LEAST.*DT*JB

I LEASED THIS 2019 AUDI Q8 IN DECEMBER 2018 FROM MY LOCAL AUDI DEALER AND IT HAS HAD SO MANY TECHNICAL ISSUES FROM THE START. I'VE HAD IT IN FOR SERVICE ISSUES 5 OR 6 TIMES. IT KEPT SHOWING THE OIL SYMBOL AND SAID THERE WAS TOO MUCH OIL AND WAS CHECKED AND THEY SAID IT WAS JUST A COMPUTER ISSUE. THEN THEY REPLACED A PART AND IT HAPPENED AGAIN NOT LONG AFTER. THEY THEN CLAIM THE REPLACEMENT PART WAS FAULTY. SINCE THE BEGINNING, IT HAS HAD ISSUES ACCELERATING WHEN IT IS IN THE ENERGY SAVING MODE, WHICH IS DEFAULT AND YOU HAVE TO DISABLE IT EVERY SINGLE TIME YOU USE THE CAR. THE CHECK ENGINE LINE HAS BEEN ILLUMINATED MULTIPLE TIMES AND WHEN SERVICED, THEY CLAIM IT IS SAFE TO DRIVE AND THAT AUDI IS WORKING ON A COMPUTER FIX TO THIS PROBLEM. NOW THE "DRIVE SYSTEM: MALFUNCTION! PLEASE CONTACT SERVICE" LIGHT IS CONSTANTLY ILLUMINATING AS IS THE CHECK ENGINE LIGHT (PICTURE ATTACHED). THIS IS BY FAR THE MOST EXPENSIVE CAR I HAVE EVER HAD AND IT HAS HAD MORE ISSUES THAN ANY OTHER CAR I HAVE HAD. I'M NOW VERY CONCERNED THAT I AM PUTTING MYSELF AT RISK FOR DRIVING THIS CAR.

WHEN DRIVING IN ANY STANDARD DRIVING MODE, WHEN YOU START TO COME TO A STOP WITH AUTO S/S ENABLED (E.G. SLOW DOWN) TO LESS THAN 6MPH, THEN ACCELERATE AGAIN, THERE IS A CONSIDERABLE LAG FOR THE VEHICLE TO START ACCELERATING AGAIN (ABOUT 1-2 SECONDS). THIS IS ESPECIALLY DANGEROUS WHEN MAKING LEFT TURNS WHEN THERE IS CROSS TRAFFIC AS THE VEHICLE OFTEN DRIFTS INTO THE INTERSECTION AND YOU CAN'T QUICKLY ACCELERATE AWAY. HAVE HAD MANY CLOSE CALLS AND THE ISSUE IS EASILY REPLICABLE ON ANY 2019 Q8.

THROTTLE LAG FROM A NEAR (BUT NOT FULL) STOP. IF COMING TO ROLLING STOP, FROM 1-8 MPH, AND THEN HIT ACCELERATOR, THE CAR ENGINE REVS BUT NO ACCELERATION TO VEHICLE. AFTER A 2-3 SECOND DELAY, CAR WILL LUNGE AND ACCELERATE NORMALLY. SCARY WHEN NEED TO ACCELERATE FROM A NEAR ROLLING STOP. LEFT HAND TURNS ESPECIALLY DANGEROUS. EXPLAINED ISSUE TO DEALER, AND Q8 CAR FORUMS HAVE SAME ISSUE. DEALER SAYS FUNCTIONING "NORMAL", WHICH I DISAGREE IT IS NOT. I HAVE TRIED ALL SETTINGS FOR START/STOP, TRANSMISSION SETTINGS, ETC., AND NOTHING FULLY ALLEVIATES THE PROBLEM. THIS IS NOT EPISODIC AND A CONSISTENT, REPRODUCIBLE DANGEROUS ISSUE.
