NHTSA Complaint #11266013 — 2019 AUDI Q8

THERE IS A HUGE (SEVERAL SECONDS) AND DANGEROUS LAG WHEN THE CAR SLOWS DOWN TO THE POINT THE START/STOP SYSTEM KICKS IN (AND STOPS THE ENGINE) AND ACCELERATION IS IMMEDIATELY NEEDED (E.G. THE CARD DOES NOT COME TO A COMPLETE STOP.) IN THAT SITUATION, PRESSING THE ACCELERATOR WILL RESULT IN THE ENGINE STARTING AGAIN IMMEDIATELY (AS IT IS SUPPOSED TO) BUT THE CARD WILL NOT ACCELERATE AT ALL NO EFFECT FOR UP TO 3 SECONDS AND THEN IT WILL SUDDENLY START MOVING TOO FAST WITH A JOLT (DEPENDING ON HOW HARD YOU WERE PRESSING THE ACCELERATOR) THIS SITUATION HAPPENS VERY FREQUENTLY (DAILY FOR ME), INCLUDING IN THE CONTEXT OF LEFT TURNS WHERE CARS ARE COMING IN THE OPPOSITE DIRECTION, MAKING IT A SEVERE SECURITY ISSUE. THIS PROBLEM IS NOT CAUSED BY TURBO LAG. IT IS MOST LIKELY CAUSED BY THE SOFTWARE FAILING TO DOWNSHIFT BECAUSE IT BELIEVES THE CAR IS COASTING. THIS ISSUE IS NOT ISOLATED AND HAS BEEN REPORTED BY PLENTY OF OTHER AUDI Q8 USERS. THERE IS A LONG THREAD ONLINE DISCUSSING IT: HTTPS://WWW.AUDIWORLD.COM/FORUMS/AUDI-Q8-227/INTRO-AUTO-START-MAJOR-THROTTLE-LAG-ISSUE-2966888/PAGE2/
