2019 Audi 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.

AUTO START/STOP IS TURNING OFF THE ENGINE AND PUTTING THE CAR IN NEUTRAL BEFORE THE VEHICLE IS COMPLETELY STOPPED. IF YOU NEED TO ACCELERATE SUDDENLY TO CLEAR AN INTERSECTION, IT TAKES A FEW SECONDS FOR IT TO START BACK UP AND MOVE THE VEHICLE. LIKE MOST PEOPLE DO, THE THROTTLE GETS PRESSED HARDER IN THE HOPES OF THE VEHICLE MOVING. BY THE TIME THE VEHICLE STARTS BACK UP I'M 3/4 TO THE FLOOR WITH THE THROTTLE WHICH CAUSES THE VEHICLE TO TAKE OFF LIKE A ROCKET. THIS IS OVERLY AGGRESSIVE START STOP IS DANGEROUS. IT SHOULD OPERATE LIKE OTHER SYSTEMS AND NOT SHUT OFF THE ENGINE UNTIL IT IS AT A COMPLETE STOP. I HAVE TAKEN MY CONCERNS TO MY LOCAL DEALER AND THEY TELL ME THAT IT IS OPERATING AS DESIGNED.

THERE IS A SIGNIFICANT LAG IN THE POWER TRAIN OF THE AUDI Q8 AFTER BREAKING TO A COASTING SPEED AND THEN ATTEMPTING TO ACCELERATE AGAIN. THE GAS PEDAL IS COMPLETELY UNRESPONSIVE FOR 2-3 SECONDS DURING THIS TIME. DANGEROUS DELAY IN THROTTLE RESPONSE DUE TO AUTO START/STOP OR MILD-HYBRYD SYSTEMS AND CAUSING VEHICLE TO COAST WHEN SLOWING DOWN AT A YIELD SIGN OR INTERSECTION ETC BEFORE TRANSMISSION RE-ENGAGES. THE VEHICLE IS POWERLESS FOR SEVERAL SECONDS DESPITE APPLICATION OF GAS PEDAL, CAUSING ONCOMING TRAFFIC TO POTENTIAL COLLIDE. ALREADY REPORTED TO AUDI SERVICE BUT THEY SAID IT'S NORMAL, WHICH I TOTALLY DISAGREE

AUTO START/STOP FEATURE KILLS ENGINE PRIOR TO VEHICLE BEING COMPLETELY STOPPED RESULTING IN THE DRIVER NOT APPLYING ENOUGH BRAKE "FORCE" TO KEEP THE VEHICLE STATIONARY AFTER THE ENGINE'S RE-IGNITION. WHEN THE ENGINE SUBSEQUENTLY STARTS, THE THE VEHICLE IS JERKED FORWARD AND THE DRIVER NEEDS TO RE-APPLY ADDITIONAL BRAKE FORCE TO THE PEDAL IN ORDER TO KEEP THE VEHICLE STATIONARY. THIS IS A SAFETY CONCERN AS THE DRIVER IS MISLEAD TO HAVE "COMPLETE CONTROL" OF THE VEHICLE WHEN BRINING IT STATIONARY THE FIRST TIME, THEN SUBSEQUENTLY HAVING TO RELY ON "QUICK REFLEXES" TO COUNTERACT VEHICLE BEHAVIOR TO AVOID COLLISION (FROM THE VEHICLE IN FRONT OF YOU, OR FROM INTERSECTING TRAFFIC). AUDIO DEALERSHIP PERFORMED SEARCH OF OPEN CAMPAIGNS & RECALLS. NONE CURRENTLY AVAILABLE FOR THIS MODEL. SERVICE CENTER PAPERWORK INDICATES "COULD NOT REPLICATE CUSTOMERS CONCERN", BUT I WAS PROVIDED EXTENSIVE TRAINING ON HOW TO 'DISENGAGE' THE AUTO START/STOP FEATURE (IF THERE'S NO PROBLEM, WHY DISENGAGE IT?). AUDI CUSTOMER EXPERIENCE (1-800-822-2834) IS UNABLE TO PROVIDE ADDITIONAL GUIDANCE AND RELIES ON THEIR SERVICE CENTERS TO HAVE THE FINAL WORD IN VEHICLE ISSUE RESOLUTION.

THE VEHICLES AUTO START/STOP FEATURE PUTS THE DRIVER IN COMPROMISING SITUATIONS WHEN POWER IS DEMANDED FROM THE ACCELERATOR AFTER AN ENGINE POWER-DOWN. THE ENGINE DOES IGNITE TIMELY, (AS SOON AS THE BRAKE PEDAL IS RELEASED) BUT THE DELIVERY OF MOVING POWER IS DELAYED (LAG PERIOD) FOLLOWING AN AUTO "SHUT-OFF AND LEAVES THE VEHICLE IN COMPROMISING SITUATIONS WHERE NO POWER CAN BE DEMANDED FROM THE DRIVETRAIN. WHEN THIS DELAY PERIOD (LAG) HAS PASSED, AND POWER IS FINALLY TRANSFERRED TO THE WHEELS, THE VEHICLE EXPELS THE DEMANDED ENERGY FORCEFULLY, JERKING YOU FORWARD. I FIND THIS TO BE A SAFETY CONCERN PARTICULARLY FOR LEFT HAND (YIELD) TURNS WHERE ACCELERATOR RESPONSIVENESS IS CRITICAL BOTH THE PASSENGERS OF THE VEHICLE AND ONCOMING TRAFFIC. AUDI DEALERSHIP CHECKED OPEN CAMPAIGNS, RECALLS BUT "CANNOT REPLICATE" CUSTOMERS CONCERN. THEY DID HOWEVER, TRAIN ME ON HOW TO "DISENGAGE" THE AUTO START/STOP FEATURE, BUT THIS NEEDS TO BE DONE AT EVERY STARTUP. (IF THERE IS NO PROBLEM, WHY DISENGAGE IT?) AUDI EXPERIENCE CENTER (1-800-822-2834) SAYS THEY RELY ON THE JUDGMENT OF THEIR SERVICE CENTERS AND CANNOT PROVIDE FURTHER GUIDANCE. *TR

WHEN TRYING TO ACCELERATE FROM A STOP THE CAR EXHIBITS A 3-4 SECOND DELAY BEFORE ACCELERATING. THIS IS A DANGEROUS CONDITION WHEN TURNING INTO TRAFFIC OR WHEN NEEDING TO QUICKLY ACCELERATE AWAY FROM A HAZARD. IT ALSO CREATES TRAFFIC BACKUPS BY DELAYING LIGHT CHANGES FOR VEHICLE BEHIND. THE VEHICLE AS IT CURRENTLY PERFORMS IS A SAFETY RISK.

VEHICLE WILL HAVE A DELAY (1-3 SECONDS) WHEN PRESSING THE GAS PEDAL WHILE THE CAR IS IDLE, CAUSING A DANGEROUS SITUATION AND LEAVING THE VEHICLE VULNERABLE TO CROSS TRAFFIC, AS IT ROLLS FORWARD INTO TRAFFIC. VEHICLE THEN JOLTS FORWARD AS IT FINALLY ENGAGES. HAS CONTINUOUSLY HAPPENED SINCE PURCHASING THE VEHICLE. WE HAVE REPORTED IT ON MULTIPLE OCCASIONS TO OUR DEALERSHIP, YET THEY BASICALLY SAY THERE IS NOTHING THEY CAN DO OR GIVE US THE RUN AROUND. THEIR SOLUTION WAS TO TURN OFF THE AUTO STOP FEATURE, WHICH SEEMED TO WORK AT FIRST, BUT NOW THE VEHICLE IS EXHIBITING THE SAME PROBLEM, EVEN WITH THE AUTO STOP DISABLED. THINK IT HAS TO DO SOMETHING WITH THEIR NEW MILD-HYBRID SYSTEM. IT IS NOT WORKING THE WAY IT WAS INTENDED. PLEASE LOOK INTO THIS MATTER BEFORE BEFORE A SERIOUS INJURY OCCURS.
