The contact owns a 2019 Audi Q8. The contact stated that while driving at an undisclosed speed, a central locking malfunction warning sign was displayed. The contact stated that later when a rear passenger attempted to exit the vehicle, the door failed to open. The driver’s and passenger’s side rear doors failed to open. The vehicle was taken to a dealer where it was diagnosed with a failure related to Technical Service Bulletin: DTC B14FF29. The vehicle was repaired under Warranty. The contact stated that the failure reoccurred, and the dealer was made aware of the failure; however, the contact was informed that the vehicle was no longer under Warranty. The vehicle was not repaired. The contact stated that it was a known failure. The manufacturer was made aware of the failure and advised the contact to have the vehicle diagnosed before any assistance would be provided. The failure mileage was approximately 9,800.

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.

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, diagnosed, or addressed. I was also not provided clear assistance or guidance regarding potential warranty consideration related to this known issue. The vehicle is currently available for inspection upon request.

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.

There is helicopter type of noise coming from fuel pump and it’s increasing while driving very annoying and i feel steering is loose and I notice on google same problem with so many Audi q8 and sq8

I was driving home from work when all of a sudden I got error messages: Electrical system malfunction! Please contact service; Start/ stop system: malfunction! Function unavailable. Please contact Service, yellow battery light and the car died. None of the safety features, locks, engine, or air condition worked and the car had to be towed to the dealership. Within 1 mile of the lights appearing the car died, putting my safety and those on the road at risk. I left in the middle of the street and had it towed a few hours later. I spoke to the dealership and was diagnosed and confirmed as a alternator- starter-generator issue and reading the Audi threads it is a common issue. The car has about 38,000 miles. I am the second owner and have had the car for less than 6 months and it has been well maintained.

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.

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 program and to contact them for a case number. When I called, I was told I had to wait 10 days to file or have had 3 reported incidents on record. On Februrary 14, 2023, I was told I did not qualify because my car was over 50k at the time it broke down. My mileage is 54,128. The issue began before 50k. I learned from the dealership, I qualify for the buyback because Audi extended the factory warranty on 1/31/2023 to include unlimited miles. I have an audio recording.

2019 Audi Q8 3.0T quatro with 34,102 miles incurred broken left rear coil spring. Right rear most likely will have to be replaced soon. A SUV of this age and mfg shouldn't be having broken coils. This defect appears to be happening quite often. From the dealer's quote... "Recommended service: Coil Spring Replacement - Rear: LEFT REAR SUSPENSION COIL SPRING IS BROKEN (SEE VIDEO ATTACHED) RECOMMEND REPLACEMENT OF BOTH REAR SUSPENSION COIL SPRINGS AT THIS TIME. Suspension coil springs support the weight of the vehicle and determine the height at which it sits on the road. The springs allow the suspension system to move and adapt to changing road irregularities; they are under extreme pressure. $2,562.60"

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.

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.

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 NHTSA ID Number: 10233615 published on 3-29-23 (the original TSB was NHTSA # 10158643 published on 4-1-19). The Manufacturer Communication Number: A6923872058455_6 I am concerned that there could be a safety issue while the seatbelt is in this twisted state. Thankfully I have not been in any accidents/incidents where the seatbelt malfunctioned. But how can I confidently be assured that the seatbelt will continue to function properly? 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. They claim that it was never covered under warranty and that they repaired it each time for free. This was the first I had heard that is wasn't covered under my warranty. I escalated this issue to Audi of America, reference #05805277. I heard back today that the dealer claims "outside influence" as the cause of this seatbelt problem. Therefore, they will not repair it as it does not constitute a manufacturer's defect. I do not feel safe driving with my seatbelt in this condition. I am hoping that the NHTSA can guide me in the right direction for a resolution to this matter.

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.
