2019 Audi Q8 owner complaints

Electrical malfunction displayed on dashboard with every system in the car shutting down within seconds. I was stranded on the freeway shoulder. Maybe an issue with the alternator.

alternator failed, multiple electrical/ computer systems shut down, eventually left me stranded.

48v Starter Generator went bad. Vehicle shut down on the high way. I have been without my car for nearly a month as the part is on back order, and there is no ETA for the part.

Driving down the road when sensors stopped working. Car read electrical system malfunction and engine shut down. Had to coast to the shoulder. This is a known safety issue, and should be completely recalled.

An "Electrical System Malfunction" warning, check engine light and the battery light came on. Was informed to notify service. Few hours later multiple system failure started to appear. Dashboard went dark and I was unable to tell the speed of the vehicle. The window rolled down on it is own. After coming to a stop the vehicle was unable to start again. Dealer informed me the "affected parts" are being ordered. No further updates were available.

While driving, all the warnings came on the dash. "Electrical Malfunction", "Child seat belt malfunction", "Start/ stop malfunction", "Steering Wheel malfunction" "Power Brake malfunction" and when I came to a stop, the car completely stopped. I could not put it into neutral to push it out of the road so my car blocked a lane on a highway making it very dangerous. 2 service reps from 2 different Audi dealerships have confirmed that is this a known defect with the v48 generator/ alternator

Car showed “electrical system malfunction” while driving. Said that the start/stop system failed. Proceeded to say that the rear brake light not functioning while driving, which would pose a safety risk to all drivers and myself.

Vehicle lost all power and control while driving 45mph. First electrical system failure warning came on. Within 2 minutes the transmission slipped into neutral and 15 seconds later the vehicle lost power and I coasted to a stop. I was told by Audi dealership service that the starter generator failed. They mentioned they currently have over 20 vehicles in their shop and over 25 at their other location with the same problem. They also said over 1,000 cars nationwide had same problem and the part to repair is back ordered and no reasonable estimate of repair time.

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 o

This vehicle as a serious intermittent issue with throttle lag. When pulling out of parking lots if you do not come to a complete stop the throttle seems to lag 1-3 seconds. Then it surges forward when it finally does move. As others have said it does not happen 100% of the time which makes it even worse. You never know if it's going to go or wait a second or two before it moves. Being in sport mode does help but who can remember to engage that every time you start the car. I have had several close calls due to this issue. I refuse to let my daughter drive the car because of this issue. I've discussed it with the dealer but they have no fix or acknowledgment of the issue.

Electric System Mal Function. The Car was flashing all signals. It asked to pull over and said there is a danger of car turning over. We called audi assistance. The tow truck driver could not load the car as the wheels were all locked up.

On multiple occasions, q8 will not accelerate when gas pedal applied for roughly 1-3 seconds when coasting to a stop or immediately coming out of a stop, causing the vehicle to remain stationary although gas pedal is applied. Once the vehicle responds to the depressed accelerator, after a delay, then the auto can accelerate beyond the requested acceleration. It feels like the vehicle is trying to decide whether or not to respond to the depressed accelerator, leaving the vehicle vulnerable if trying to cross traffic, accelerate from a stop sign, or turn left between oncoming traffic. The problem feels intermittent although it feels like its becoming more common. Vehicle responds this way whether or not the auto stop feature is engaged or not.

The car has a several second delay when pressing the gas pedal in the engine idle auto on/off feature. I have not heard of any recalls or fixes to this problem. Dealer has no fix for problem.

Critical Failure - Alternator/48v Generator Issue in Audi Q8 Prestige. By now, I am well aware that the problem I'm experiencing is in the top 25 repair issues for Audi and currently there are 15,000 cars affected in the United States according to my dealer, waiting for these parts. Out of nowhere while driving on an interstate, at a high speed I got all mix of signals and the amount of time to react between the first sign that something is going wrong to the "stop operating the vehicle and pull over to the side message" and vehicle shut down, without ability to start is within just few minutes from each other. First I get a random battery error message. Battery light had popped on the dash panel. Then, system malfunction message, the whole array of different malfunctions. Noticed odd thin

My 2019 Q8 has less than 35K miles and has had breaks and rotors repaired three times and needs them again. The breaks pulsate and wear down at an excessive rate, the stock breaks are not a good enough product for the weight of the vehicle. I’ve raised this issues with the dealership multiple times and this is my 2nd Audi SUV with break issues.

Wheel arch on the front passenger side flew off on the highway. There was no visible issues that the piece was loose as it’s been on the car securely for 45k miles.
