NHTSA 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 w

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.

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, 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 “IMMEDIATE ATTENTION,” 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 pr

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 multiple Technical Service Bulletins. Specifically, the EA839 water pump uses a vacuum-operated diaphragm to control coolant flow. When the pump's internal seals fail — as they predictably do — coolant migrates directly into the engine's vacuum system, contaminating components far beyond the pump itself. Industry experts and Audi forums alike describe this failure mode as inevitable on this platform: not a matter of if, but when. This is a design defect manifesting at a fraction of the mileage at which any reasonable owner would expect a cooling system component to fail. Audi of America has issued multiple TSBs addressing coolant pump failures on this exact engine platform, and previously extended warranty coverage for Q7 and Q8 vehicles, including those built during the same production window as the vehicle in question. Our concern is this issue can cause the engine to seize while driving and Audi's repair costs for this known issue have been quoted minimally at $5,519.76

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 addressing the underlying cause of the warning. Following this, I made multiple attempts to have the vehicle properly diagnosed. I experienced difficulty obtaining assistance, including calls being disconnected, and I was not provided meaningful support or a thorough evaluation of the issue. Shortly after leaving the dealership, the vehicle began producing abnormal knocking noises and rapidly became unsafe to operate, requiring it to be towed. This situation presents a significant safety concern, as a sudden loss of power or drivability while driving can increase the risk of an accident, particularly in traffic conditions where maintaining speed is necessary. The condition has since been confirmed by a service provider as a major mechanical failure. Additionally, I have received documentation from the manufacturer indicating a known issue related to piston skirt defects associated with this vehicle. Despite the vehicle being in the dealership’s possession for an extended period, this issue was not identified,

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.

Due to a leak in the rear axle that is connected to the differential, it caused the entire differential to fail. The bearing within the differential completely failed due to contaminated oil. The Q8s are known to have this occur but only in year models 2020-2022. My Q8 is a 2019 and Audi is aware of these issues given technical service bulletins available but doesnt want to take responsibility as this may be a continuing manufacturing issue arising. My vehicle only has 65k miles on it and Audi admits this is rare. Due to a misdiagnosis in June of 2025 (oil leak), Audi of Seaside Monterey caused the complete failure of the differential in December of 2025 by not doing a deeper diagnosis earlier to resolve the catastrophic failure. This is a safety concern and very expensive. A new differential costs $12k which has been expected to pay with no accountability. I am currently in an active case with Audi Seaside and the BAR to come to a resolution.

Air Bags

Dash Delamination: The leather dashboard is experiencing severe delamination and pulling away from the substrate, specifically in the area surrounding the passenger-side airbag. I believe this condition poses two significant safety risks: Airbag Interference: The detached and warped material may obstruct, delay, or alter the deployment path of the passenger-side airbag during a collision. Visibility and Distraction: This is a material defect, not wear and tear, and it poses a potential safety concern due to the reflection/glare on the windshield, as well as the distraction it causes while driving. Audi has acknowledged this "process weakness" and issued a Limited Warranty Extension (AWA-23-11) for 2019-2020 Q8 models. Despite this, my request for a safety-related repair was denied due to over 80K. The issue should be considered under mileage. I am requesting that the NHTSA investigate this defect to determine if it constitutes a safety non-compliance with FMVSS No. 208, as the structural integrity of the dashboard is vital for proper airbag performance. Thank you for your assistance in ensuring the safety of this vehicle.

Faulty water pump → allowed coolant to migrate into the vacuum lines (a place coolant should never be). •This led to turbo underboost faults (loss of power) even though the turbo itself is fine. •The contaminated vacuum system now requires replacement of the vacuum shut-off valve and possibly other vacuum components. •Because of how the parts are placed, the repair requires removing the front bumper, and once it’s reinstalled, the safety systems/sensors must be recalibrated.

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.

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 pay the extra to make sure it will be taken care of properly! numerous same issues engine mounts after 50k MIles

While driving down the freeway to the dealership a electrical system malfunction message came across the display. I continued on to the dealership and suddenly started getting system failures. One by one it popped up and said every single system failure including brakes and steering system malfunctions. Then it said transmission malfunction and I immediately lost all forward propulsion. The engine just revved when I hit the gas. I had to fight my way over to the shoulder where the vehicle came to a stop and would not even let me set the parking brake or engage park. I sat I the vehicle on the freeway between an on ramp and the moving lanes until the tow truck showed up. The failure turned out to be the alternator which I'm told is a very common issue for most audi vehicles. The vehicle was towed to the dealership and they replaced the alternator at no charge due to an extended warranty already granted on the failing alternators. The repair was made and vehicle was returned but the same alternator was put into the vehicle that was in it originally as it has not been updated. This created a major safety risk as power was lost while traveling at freeway speeds.

I am the owner of a 2019 Audi Q8, purchased on 8-8-19. I have had repeated issues with the driver's side seatbelt twisting and retracting the twisted portion up into the B pillar. I have had this issue repaired 3 separate times at my local dealership, most recently in June of 2023. Just 2 weeks after having it repaired, it twisted for the fourth time in early July. It has therefore been witnessed and documented by the dealership each time it has been repaired. The issue has never happened to me and has always happened after my husband has driven my car. So I cannot tell you what exactly is happening to cause this. There is a TSB regarding this problem.

It is not normal for a seatbelt to due this. I contacted my dealership on July 21 to have it repaired again under warranty, but they told me that I would have to pay to have it fixed again.

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.

And the excuse Service gave us is No ETA on the Parts From Germany. They have new cars coming in and they don't have parts coming in??. We are stuck in the middle, can't trade in or sell our cars. Right now this Q8 is a huge junk without any functional purpose. Some of the owners have been waiting for this fix for 3, 4 months. The government really should step in to find out what is going on on AUDI. It can't be parts shortage. It is some problem what AUDI simply can't fix. AUDI USA is also very unreliable. They direct us to our individual dealer, saying they can't do anything about it. They don't take any responsibly. We have no one to file complaint to.Most of the cars are still in the warranty, it is simply unbelievable.

On 12/12/2022 I was driving and the Q8 lost power and I coasted to a stop. All lights on driver panel were flashing or sequencing through. After sitting on the side of the road for 5 or so minutes I tried starting the car again. This time it started and I drove another 8 miles almost to my home when the car again just died in the road. This time I couldn't get it to restart. I had to have it towed to my local garage as my dealership was an hour and fifteen minutes away. The car has been diagnosed with needing an alternator, which no one including the dealerships have because this is a problem with many vehicles. It has now been over two months without my car.

In September 2022, I contacted the dealership to schedule my 50k service after observing a yellow battery light indicator flash on and then resolve itself by turning off. The mileage on my Q8 was approximately 44K at this time. I was also experiencing a passenger seatbelt warning issue despite no one in the passenger seat. The soonest the Audi service department could get me scheduled was on February 14, 2023. This has been an issue with Audi service departments at least the past 2 years. Since scheduling, I've experienced the warning issues several times On Thursday, February 2, 2023, I got a flashing yellow battery light in addition to other warnings that flashed on and then off. Because of this, I decided to take my car to the dealership for an emergency service on Friday, February 3, 2023, before traveling out of town the next week. While enroute to the dealership, the instrument panel alerted to an electrical system malfunction by displaying a yellow and then red battery icon. Multiple other warning lights for other systems malfunctioning displayed and the car stopped in traffic. My car was towed to the dealership. Once at the dealer, I was told that this was due to the generator failing and the part is on backorder due to being manufactured in Ukraine. The dealership stated this failure is apparently widespread, citing 56+ cars at this dealership and 100+ at the other with the same issue. Based upon this, the dealership informed me I qualified for the Audi USA buyback p

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
