Consumers have filed a total of 38 complaints for Q8 models.
Every tim towing a trailer and hitch weight is over 300 lbs ( specification shows 770 lbs max, original audi hitch installed came with the car ) the audi limited pre-sense warning goes on after ~45 min drive with trailer. After that no distance warning or cruse control (adaptive) possible. After removing the trailer - the issue continues. Only solve is a new calibration of radar system at audi dealer (2 days) and same issue returns when towing a trailer again. (happen now 5 times since jan 2020 - when we bought the car) - and we towed 2 different trailers trailer 1 - 350 lbs hitch weight, trailer 2 700 lbs hitch weight - no solve by audi provided
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!
The vehicle's start stop system or transmission seems to be sluggish leading to various bouts of hesitation especially when slowing down and coasting at a slow speed and then trying to accelerate. This was especially noticeable when attempting to turn left from a left turn lane and having the car hesitate for what felt like a second or two which could lead to a crash if someone was coming in the other direction.
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
After most recent software update, the backup camera does not automatically engage or displays a black screen. The backup camera previously worked fine. Other times, it will display the front facing camera instead of the rear camera despite being in reverse.
Every time it rains the technology sensors malfunction ex: the blind spot, lane change assist, intersection assist, audi pre sense, and rear cross-traffic assist. Also the center console has blacked out of a few occasion when the vehicle was idle and moving. And overtime i have brought it in for repair and showed the video, they state the diagnostic does not pick up any errors and that the vehicle is performing properly despite the videos i have provided. The final result is always they have performed a software update!
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.
The car will unpredictably lose all power for 2-3 seconds. This has more than once nearly caused a fatal accident!!!!!!! The manufacturer is aware of the problem but unable or refusing to fix it. Please save lives today and recall the 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.
Auto start/stop is so laggy when re? Starting the engine, especially at large crossings w heavy traffic or roundabouts. I had almost 5 accidents in the past year because you anticipate oncoming traffic and from experience you know you can easily turn or go, and then you just roll a bit and there is nothing happening and you have no chance to do anything.
When start/stop system is enabled, the engine will shut off when coasting to a stop. If you try to accelerate it takes 2-3 seconds for the car to accelerate. This is extremely dangerous on left hand yield turns where there is oncoming traffic. This problem can be solved by turning off the start/stop systems or putting the transmission into sport mode which will automatically turn off the start/stop system. In addition, the car does not remember your setting when the car is turned off. So everytime you start the vehicle you have to remember to turn off the start/stop systems. Audi dealer asknowldeged the issue and performed update, but the issue still persists.
The vehicle has major throttle lag from a stop state of the car, if you are not aware, the vehicle will lag on acceleration and sudden jerk forward at full speed which is a major safety hazard if you are not paying attention. The turbos take too long to send power to the wheels and result is sudden acceleration.
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
Serious safety issue with throttle delay from dead stop to get going; does not happen all the time and it is impossible to replicate the issue; audi claims they do not know anything about this - multiple past complaints. I would not purchase this vehicle until this is resolved. It will kill someone. *tr
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
As reported by others, if the car does not quite come to a complete stop and one accelerates, there is a several second delay as the engine seems to bog down. This is related to the auto stop/start system as this delay does not happen if the auto start stop is disabled.
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.
