   I own a 2019 Audi Q8 3.0 TFSI that has been regularly maintained and serviced through authorized Audi dealerships. The abnormal engine ticking/knocking did not suddenly begin at 91,000 miles. A similar noise could be heard earlier, but it was not identified by Audi service as an internal engine/piston problem. Because the vehicle continued to be serviced by Audi, I believed the sound was related to the fuel injectors or normal engine operation. At approximately 91,000 miles,…

   My car is a 2019 Audi Q8 3.0L V6 with only 41,831 miles. My emergency light went on and I brought it my locat Audi Dealer. The inspection revealed that the coolant pump was leaking internally, contaminating the entire vacuum system with coolant. This is not a maintenance failure or the result of owner neglect. It is a well-documented, inherent design defect in the EA839 3.0T engine platform that powers the 2019 Q8, a defect that Audi of America has acknowledged through…

   I own a 2019 Audi Q8. The vehicle was in the dealership’s possession for approximately three (3) weeks for service. During that time, I was not informed of any significant mechanical concerns or issues. After retrieving the vehicle, it displayed an oil pressure warning while in operation. I immediately returned the vehicle to the dealership for evaluation. At that time, the dealership added oil (“topped off” the vehicle) and released it back to me without identifying or…

   Piston slap issues. The manufacturer is aware of the engine failure issues. They extended the engine warranty coverage from 50k to 80k miles knowing that the engine piston slap is an extreme issue but they won’t issue a total and complete recall. Owners have to identify that issue and have to specifically bring it in to have it bore scoped. If an owner isn’t aware of the noise and goes over the 80k miles then they are not held responsible for the complete and utter engine…

   being quality Engineer, why is this thing failing , and why are there no recalls? Amazing how they design these things to fail right at 50k miles. From what I hear, the audi's are notorious for not making these replacements simple and specialized tools are needed. I wouldn't change anything engine related unless you have issues like engine shaking, or rattling sounds stemming from the engine mounts. And if you get major work done, it is probably best to go to the dealers and…

   The alternator failed causing the vehicle to shutdown in the middle of traffic. I was on a surface road not the highway so I was able to get local police to assist. When it failed there was no car electrical system function, so I could not even turn on my emergency blinkers. This is apparently very common on Audis, as the same part was used to replace the alternator…. It took a month for the dealership to get the part in stock.

    Electrical system malfunction caused the car to come to a stop in the middle of a busy highway. The vehicle needed to be pushed off to the side of the road by other parties as steering became increasingly difficult to navigate to the side of the road. The vehicle was stuck in neutral and could not start the engine to drive again. The vehicle needed to be towed to the closest dealership for further investigation.
