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, the noise became noticeably worse. At 91,623 miles, Audi San Jose diagnosed the knocking as related to the engine pistons, classified it as requiring \u201cIMMEDIATE ATTENTION,\u201d opened Audi TAC case SF-1690700, and confirmed that all six pistons require replacement.  Audi provided a repair estimate of $22,466.21.  I have since learned that Audi has acknowledged a piston-skirt issue through an 8-year/80,000-mile limited warranty extension, and I have found numerous owners reporting similar piston knocking/piston-slap and major engine repairs.  My vehicle is now beyond the 80,000-mile limit, but the noise existed earlier and was not recognized as a piston problem. Given the vehicle's Audi maintenance history and the failure of all six pistons, I am concerned this represents a premature engine defect rather than normal wear.  I am reporting this so NHTSA can investigate similar failures, including those diagnosed after Audi's extended-coverage mileage limit, and the potential risk of major engine damage or loss of propulsion.","products":[{"type":"Vehicle","productYear":"2019","productMake":"AUDI","productModel":"Q8","manufacturer":"Volkswagen Group of America, Inc."}]}]}
