AUDI Complaints

For more than three months, my Audi Q6 e-tron has been sitting at the dealership with an unresolved issue that they have failed to diagnose or repair. This prolonged inaction is unacceptable, and the near-total lack of communication or meaningful updates only compounds the problem. It is alarming that a premium vehicle equipped with advanced safety technology remains inoperable for such an extended period. This situation raises serious concerns about both the reliability of the vehicle and the dealership’s ability to address critical issues. When safety systems are involved, delays of this magnitude are not just inconvenient—they are dangerous and erode customer trust. I demand that Audi take immediate action to provide a definitive resolution, whether through a successful repair or an appropriate remedy under the vehicle’s warranty and applicable consumer protection laws. Leaving a customer without answers for months while a safety-related issue persists is unacceptable and must be addressed without further delay.

While driving a 2018 Audi SQ5 with the EA839 3.0T engine, a coolant warning light activated and engine temperatures began rising to 210-215°F. The vehicle was pulled over immediately. Upon inspection the coolant reservoir was found to be nearly empty with dried coolant residue on the exterior indicating an active leak. The vehicle was towed to an authorized Audi dealer who confirmed via multi-point inspection that the water pump, shut off valve, and vacuum system require replacement due to coolant leakage, with a repair estimate of $5,324.87. This is a known defect in the EA839 engine platform. Audi has issued multiple Technical Service Bulletins on this issue and is currently named in active federal class action lawsuit Larr et al. v. Volkswagen Group of America, Case No. 2:26-cv-05678. The vehicle was confirmed by the authorized dealer and the component is available for inspection.

On XXX, I was driving my Audi Q6 e-tron southbound on [XXX] in the HOV lane at highway speed with my family inside. Without warning, the vehicle suffered a complete power failure, dropping instantly to zero acceleration.Because I had no propulsion, I was forced to coast the unpowered vehicle across three lanes of active traffic to reach the right shoulder. Trailing traffic approaching quickly from behind narrowly avoided rear-ending us, and the vehicle side-slipped multiple times during the coast. It is a miracle my family survived the maneuver.Once I managed to get the car stopped on the shoulder, the vehicle exhibited erratic and dangerous electronic behavior. The car remained running and flatly refused to shut off despite my attempts. Furthermore, for some completely unknown reason, the steering wheel would not stop moving and shaking back and forth (right and left) entirely on its own while the vehicle was stationary.The California Highway Patrol (CHP) arrived to secure the scene. I used the vehicle's emergency contact button to contact Audi. While waiting, I called Calabasas Audi, where the car was being towed, and spoke to an employee named Ark. Ark stated he had never heard of this happening (the car not shutting off and the steering wheel shaking). He instructed me to push the door lock/unlock button to see if it would reset the system, but this did nothing. The vehicle was completely disabled and unsafe to operate. This severe defect put my family's lives at risk, and I have zero trust in this vehicle. I request an immediate safety investigation.

The lane keeping assistance system was engaged as we were traveling at approximately 55 mph and started around a right hand curve. The system aggressively jerked the car to the left and with the wheels on the rumble strip associated with the center double yellow lines. There was traffic flowing the opposite direction and we would have been head to head with an oncoming truck had the driver not stopped the car. The car has been to the dealer, they can not reproduce any issues with the system and have asked that video be taken the next time this happens which is not feasible nor safe. I have not driven with the lane keeping assistance on since this incident, this was not the first time that I had issues with it trying to turn the car out of a lane, and I do not feel comfortable with it engaged any longer. There were no warning lights or messages.

I had adaptive cruise control on in moderately flowing traffic on the highway. Without warning the adaptive cruise control on it's own turned off/disengaged and slammed on the brakes. I had not changed lanes nor had anyone moved in front of me. The weather was clear. My safety and the safety of those behind me was put at risk. I've taken the vehicle to the dealer and they have not been able to reproduce the issue yet. They inspected the vehicle and took it for an initial 7 mile test drive, said they didn't find any problems and tried to return the car. There were no warning lamps or messages before or after the incident. I didn't notice any when it happened as I was focused on trying to avoid an accident. Prior to the incident the adaptive cruise control has turned off multiple times with the message " Adaptive cruise assist: currently not available" for no apparent reason, but this is the first time hard breaking was applied.

On my 2017 Audi Q7 with 93169 miles, I am getting the error message along with a warning lamp that states: "Front right side marker light defective." The light actually works however I am getting this message. If the light were to actually go out it would affect the safety of my vehicle. I hear this is a common issue with the 2017 Audi Q7s and is very costly to fix at the dealer because the entire headlight assembly is usually replaced by the dealer. My vehicle is available for inspection if needed.

A vehicle diagnostic scan dated 04/15/2026 showed electrical communication faults involving vehicle control modules. The scan showed U014100, described as “Lost Communication With Body Control Module ‘A’,” with status listed as passive/sporadic. The scan also showed U112100, described as “Data bus message missing,” with status listed as active/static. This is being reported as a safety concern because body-control module, gateway, and data-bus communication faults can affect vehicle electrical functions, warning systems, access/locking systems, lighting or body-control functions, driver information, and other vehicle systems that rely on module communication. The concern is especially important because the vehicle has had multiple intermittent electrical/body-control symptoms, including fuel-door/tank-flap electrical faults and other reported intermittent vehicle electrical concerns. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and the diagnostic scan report, electrical-system records, service communications, and related repair records are available if requested.

A vehicle diagnostic scan dated 04/15/2026 at approximately 88,502 miles showed a stored transmission electronics fault: P084100, described as “Transmission fluid pressure sensor/switch A range/performance,” with status listed as passive/sporadic. This indicates a transmission / powertrain control concern involving the transmission fluid pressure sensor, transmission electronics, wiring, control logic, pressure monitoring, or related powertrain components. The vehicle also has prior transmission/powertrain history, including a March 2023 transmission-pan-gasket concern documented in service records, so this later transmission electronics fault is being reported in that broader powertrain context. This is being reported as a safety concern because a transmission fluid pressure sensor or transmission-control fault can affect shifting, drivability, delayed engagement, slipping, harsh shifting, limp mode, reduced power, drivetrain damage, or loss of propulsion while driving. Even if the fault is intermittent, a transmission-control issue may create an unsafe condition if it occurs in traffic or during acceleration, merging, turning, or normal driving. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and the diagnostic scan report, transmission-related records, service records, manufacturer communications, and related communications are available if requested.

My 2018 Audi Q7 3.0T Quattro is experiencing extreme oil consumption — dropping from full to minimum level in approximately 230 miles. This is approximately 14x beyond Audi's own threshold for excessive oil consumption of 0.5 quarts per 1,000 miles. Documented timeline: May 2026 (88,692 miles): Oil change required 2.2 extra quarts beyond standard 7.2qt fill. Low oil light triggered during highway travel. June 27, 2026 (90,200 miles): Authorized Audi dealer formally documented "oil consumption is very high" in their service system and scheduled an official oil consumption test. June 28, 2026 (90,351 miles): Audi MMI system showed oil near minimum after only 151 miles. June 30, 2026 (90,397 miles): Audi MMI showed oil at Stage 2 warning after 197 miles. June 30, 2026 (90,430 miles): Audi MMI showed oil at minimum line after 230 miles total. All readings documented with timestamped photographs from Audi's own MMI system. The authorized Audi dealer has documented repeated oil top-offs in their service system. Audi USA Customer Care was contacted on June 30, 2026 and denied goodwill repair citing no active recall and vehicle out of warranty. An open case has been filed with Audi USA. The engine lubrication system appears defective. Oil dropping to minimum in under 230 miles without adequate warning poses serious safety risk of catastrophic engine failure while driving at highway speeds. The authorized Audi dealer has scheduled an official oil consumption test and inspection for July 2, 2026. Results will be available upon request. Vehicle is available for inspection upon request.

The vehicle has a recurring interior rattle / loose-trim concern involving interior panels, trim, speaker/subwoofer area, rear shelf, dashboard area, or related mounting components. The noise is not merely a comfort concern if it is caused by a loose component, fastener, grille, panel, or speaker housing that may move, worsen, detach, or distract the driver. This is being reported as a safety concern because loose interior trim or components can distract the driver, interfere with normal vehicle use, create uncertainty about whether a component is secured, and may indicate improper fastening, panel fitment, speaker/subwoofer mounting, or body/electrical component installation issues. If the affected trim is near safety-system areas, it should be inspected to confirm it does not affect wiring, restraint-system areas, visibility, or safe vehicle operation. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and service records, TSB-related records, photos/video/audio, issue lists, and repair communications are available if requested.
