AUDI Complaints

I was traveling at highway speeds in active, high-velocity traffic when my vehicle suffered a sudden, catastrophic mechanical failure that nearly resulted in a severe multi-car accident. Without any warning, the vehicle completely lost its ability to accelerate, flatly refusing to pick up speed or maintain momentum despite pressing the gas pedal. ?This unexpected, immediate drop in propulsion marooned me in high-speed lanes, leaving the vehicle dangerously vulnerable as oncoming traffic rapidly closed the distance behind me. Drivers behind me were forced to aggressively swerve and brake to avoid a high-speed rear-end collision. Moments after this life-threatening loss of power occurred, the Check Engine Light illuminated on the dashboard. ?Subsequent technical inspection revealed a severe engineering defect: the internal seals of the factory coolant control components failed, forcing pressurized engine coolant backward into the engine’s primary vacuum system. This pressurized fluid completely contaminated the vacuum lines, the vacuum reservoir tank, and the electronic solenoids—including the N75 boost control solenoid. By filling the vacuum infrastructure with liquid coolant, the engine was instantly starved of its ability to regulate turbocharger boost, triggering a critical "limp mode" and a P0299 underboost fault. ?The catastrophic failure of an internal cooling seal directly compromising an active drivability safety system represents an unreasonable and severe defect. It transforms a routine drive into an immediate, uncontrollable highway hazard. I am filing this report because this known coolant migration pattern presents a clear, present, and life-threatening danger to owners operating this engine platform.

I have experienced multiple events in which the there is a central locking system malfunction which renders the fob, door lock button, and at times, the door handle nonfunctional and effectively traps occupants in the vehicle.

My Audi Q6 Etron has 1 year and 10,390 miles. I was informed by the dealership that tires are already showing excessive thread wear causing a safety hazard due to lack of traction. Replacement is needed. This was never disclosed by Manufacturer or dealership until last Friday during the 10,000 mile service. Short life span was hidden to me until my first service and is affecting all Audi Q6 Etron owners.

When driving, my vehicle recieved multple warning messages at the same time. The first message was that my brake was malfunctioning, and when I went to brake, the brakes did not work. Thankfully, I wasn't going too fast when this happened and I was able to bring it down to a slow and turned into a lot. I could've easily hit another vehicle or totaled my car because the brakes simply stopped working. The problem seems to be at the maker level for Audi eTrons - I've read this has been happening. There were no prior warnings or issues whatsoever, in fact, I had a full service in February (3 months before this incident). Audi had a tow truck take it. The code for this is TSB 2072977/3. Their notes say "vehicle checked and found no communication with ABS module U012100 TSB loosened and fastened earth strap. Performed sleep cycle and softward update 30TU."

While parked in my residential garage with the engine shut off and car door closed, the vehicle suffered an un-commanded rollaway incident due to a suspected defect in the electronic parking brake or automatic-park transmission software. The vehicle was completely stopped, the driver exited the vehicle and the driver's door was closed. Moments later, the vehicle shifted out of its parked state or failed to hold, rolling backward down the driveway and colliding with a basketball pole in the driveway, causing vehicle damage. No warning chimes or dashboard alerts were observed prior to exiting. The vehicle's electronic failsafe to automatically engage 'Park' upon the door opening failed to secure the vehicle.

I am reporting recurring safety-related defects on my 2018 Audi A4 involving Automatic Emergency Braking, Forward Collision Warning, Audi pre sense/front-collision functionality, and related electrical/driver-assistance reliability. The AEB/forward-collision system has shown two unsafe intermittent behaviors. At times it has failed to activate as expected when crash-mitigation assistance appeared reasonably available. At other times it has unexpectedly warned, jolted, or applied braking when there was no apparent vehicle, object, pedestrian, or hazard close to the car. Unexpected braking or false intervention can startle the driver, create rear-end collision risk, and reduce confidence in the system. Failure to activate can also increase forward-collision risk. The system was not intentionally disabled by me, and I am not aware of any driver-caused obstruction, modification, or normal explanation. The condition is intermittent and may not appear during a brief service visit or basic fault-code scan. This concern was reported through Audi/dealer service channels, including a documented repair request identifying the AEB system as malfunctioning and failing to activate as designed. A later dealer communication stated that there were no stored AEB faults and later clarified that no work was done on the AEB system, no inspection or verification of AEB operation was performed, and confirmation of operation would require an additional estimate. I am reporting unresolved safety status because intermittent active-safety failures or false interventions may not store permanent DTCs, and lack of stored faults is not complete safety verification. I have not received final written safety closure confirming inspection, calibration review, road-test verification, factory scan/freeze-frame review, module communication review, and technical verification. No crash, fire, injury, or fatality is being reported. The vehicle is available for inspection if requested.

The contact owns 2015 Audi A3. The contact stated while parked and when attempting to input fuel into the vehicle the fuel hose sprayed fuel into the contact's clothing and shoes and began to leak under the vehicle near the rear tires. An independent mechanic was contacted. The contact mention the failure has occurred on several different occasions. The vehicle was taken to an independent mechanic where it was diagnosed that the fuel system needed to be replaced. The vehicle was not repaired. The contact was relating the failure NHTSA Campaign Number:24V110000 (FUEL SYSTEM, GASOLINE); however, the VIN was not included in the recall. The manufacturer was notified of the failure and they informed him to the local dealership. The failure mileage was 75,000.

The contact owns a 2021 Audi Q3. The contact stated while attempting to refuel the vehicle, fuel spilled out of the filler neck and fell onto the ground. The vehicle was taken to dealer, where it was diagnosed and determined that the fuel tank needed to be replaced. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 22V673000 (Fuel System, Gasoline). The manufacturer was notified of the failure and informed the contact that the vehicle was not covered because the VIN was not included in a recall. The failure mileage was approximately 67,000.

Dear Sir or Madam: I am submitting a safety complaint regarding my 2022 Audi Q3 involving water intrusion from the sunroof. At approximately 41,000 miles, approximately a month ago, water began leaking through the front edge of the sunroof despite the sunroof never being opened prior to the issue. The leak was not caused by clogged drains or lack of maintenance. Water entered through the overhead console, resulting in failure of the interior lighting system causing lights to flicker on/off and water dripping directly onto me, the driver, while operating the vehicle. These issues created a significant distraction and potential safety hazard, especially during night driving. The dealership diagnosed the issue and confirmed that the repair required modification of the sunroof assembly and track to correct a water intrusion problem. This was not a routine maintenance issue. The total cost of repair was $1,259.18, which I paid out-of-pocket. Additionally, the service advisor at the dealership stated that this is a frequent problem seen on Audi Q3 vehicles and expressed surprise that it has not already been subject to a recall. Given that this issue involves water intrusion affecting electrical components and actively interfering with safe vehicle operation, I believe this may represent a broader design or manufacturing defect impacting vehicle safety. I respectfully request that NHTSA review this issue for potential investigation and possible recall action. Thank you for your attention to this matter.

The contact leases a 2025 Audi SQ5. The contact stated that the driver's side exterior rear-view mirror position was blocking the driver's view while making a left turn. The manufacturer was contact and advised the contact to take the vehicle to the dealer for it to be test-driven. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 800.
