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.

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.

I was having noise from engine and and I received a letter from extended warranty for an production defect in piston skirt. I sent my car for an evaluation in the Audi of Manhattan and I was told that my car falls under the engine piston skirt defect.i have the pictures from Audi Manhattan inspection that the engine piston walls have scratches.i was denied coverage under extension warranty because my car was over 1752 mile over the extension warranty.this is and production engine defect and can be stranded any time soon in the high way or any other street putting me and My family in danger and any other people driving around my car if that engine stops in the middle of the street. My car has 81752 miles and the extension warranty was up to 80000 mile or 8 years. The extension warranty came to late almost after 6 years ,as this is an known problem with those engines EA839 that is found in audis Porsche VW Tuareg ect.

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

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.

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

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.

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"

I was smelling fuel from my car so stopped to have it checked and was told there is a significant spray of fuel coming from the fuel rail and hitting the electrical wires. I was told that it could go on fire at anytime and the car cannot be driven. Audi has a recall for this exact issue for 2016-2018. This is clearly the same issue but they are not issuing a recall for 2019 models and it’s extremely dangerous.

Air conditioning failure, evaporator failure; known issue with Audi Q7, Audi Q8 not included in limited extended warranty

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 makes creaking sounds when going over bumps and turning left or right.

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.

Electrical malfunction displayed on dashboard with every system in the car shutting down within seconds. I was stranded on the freeway shoulder. Maybe an issue with the alternator.

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.

While driving warning light came on electrical malfunction on highway cat lost all power following a series of light’s indicting multiple malfunction then transmission disengaged I was able to coast to a stop , was unable to get out of vehicle due to car not unlocking

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.
