2019 Audi Q8: engine failure

Filed Oct 15, 2026 · Engine · WI

the federal safety agency Vehicle Safety Complaint – 2019 Audi Q8 Prestige, 3.0L Turbocharged V6 I am reporting a serious engine defect involving piston damage and cylinder wall scoring in my 2019 Audi Q8 Prestige equipped with the 3.0L turbocharged EA839 engine. Audi of America has previously acknowledged a piston-skirt concern affecting certain vehicles equipped with this engine and issued U82 warranty-extension letters to affected consumers, extending piston-skirt coverage to 8 years or 80,000 miles. Despite this known concern, my vehicle has developed significant internal engine damage requiring major repairs. I initially reported an abnormal engine knocking noise to an authorized Audi dealership during the original factory warranty period, at approximately 47,000 miles. The dealership advised me that this noise was normal and did not correct the underlying condition. On August 25, 2026, at approximately 78,910 miles, I again contacted Audi regarding the engine concern. The earliest available dealership appointment was September 7, 2026. By the time the vehicle was inspected, its mileage had exceeded the 80,000-mile warranty-extension threshold. Audi Loves Park subsequently confirmed piston-related engine noise and cylinder wall scoring affecting cylinders 4 through 6. The dealership determined that substantial internal engine repairs were necessary. The primary safety concern is the possibility of catastrophic engine failure and sudden loss of propulsion while driving. Continued operation with damaged pistons and scored cylinders could result in additional engine damage, engine seizure, or stalling, creating a significant collision risk during highway driving, merging, or passing.

Engine overheated and dash warning light did not illuminate until coolant was completely overheated. i followed the light, pulled off the road and let the engine idle until the light when away as directed and proceeded to drive approx 10 miles total distance to work from first warning light to full engine failure with electrical system failure due to being melted and three of my cylinders were misfiring. Audi states i need a full engine replacement at my expense and is not taking ownership of failed warning system. Engine for car quoted 25-30k for replacement. total car value with approx. 80k miles is 17k. Absolutely ridiculous.

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 destruction.

engine begin to misfire and felt like it was ready to stall. within a minute of the misfiring the engine light came on. i was in the middle of highway struggling to get my vehicle to the dealership where purchased which thankfully was only 5mins away. tech heard noise coming from fuel pump near the engine and recommended replacing along with spark plug. after replacing tech advised me to take my vehicle to audi to perform a software update that will correct the misfire and prevent the MIL from illuminating. Got that done to only be presented with a knocking noise again a month or two later. Took my car back to Audi to run a full diagnostic to find out my engine is in early engine failure due to metal shavings in the oil filter. tech states shavings in the oil could originate from the fuel pump failure and the debris would have traveled into the engine oil causing critical damage to the engine.

November 18, 2022 a warning lamp of electric system problem was displayed. There is no local Audi dealer and I decided to take the vehicle to my local automotive repair shop that does non warranty repair on Audis. I drove approximately 6-8 miles after the light came on and was one half mile from the service technicians when within 300 yards the vehicle became sequentially inoperable. First power steering, then transmission, brakes , ended with engine failure. I was in rush hour traffic and unable to steer off the road so I was blocking traffic near an intersection. My flashers and power windows were all that functioned. The doors were locked. When the tow truck arrived he let me out of the car. I was not injured and the vehicle was not hit either. The vehicle was transported to Audi Beaverton Oregon and now 3 1/2 months later is still there because there are no available starter/generator units available in this country. That unit failed and was the cause for my Audi’s complete shutdown. This was a potentially very dangerous situation and needs to be reported for a recall campaign. I have read that there are thousands of similar failures of the starter/generator systems in the USA and no available parts. I still have no estimate from my Audi Beaverton dealer/sevice supervisor as to when I can expect to get my car repaired and returned to me. They have not provided a loaner vehicle and refuse to cover the full cost of a rental car. I am disappointed in Audi’s level of customer service and communication.
