AUDI Complaints

A failed (frozen) Turbocharger Wastegate Actuator. An engine warning light came on and engine had less power. It had to be replaced. There was a settled law suit for the same issue covering this item in previous vehicles settled in 2025.

On 04/16/2026 at 10:19 my car became unsafe to drive and I had multiple safety errors including: Active front assist unavailable Adaptive cruise assist unavailable Emergency assist unavailable Traffic sign recognition unavailable Adaptive light malfunction High beam assistant malfunction

My 2020 Audi SQ5 (3.0L turbo V6, EA839 engine) experienced premature water pump failure at 64,361 miles. Coolant leaked into the vacuum system, damaging the vacuum unit and related components. Failed parts are available for inspection. Safety Risk: Loss of coolant circulation causes rapid overheating and risk of sudden engine failure at highway speeds, creating a collision hazard. Coolant intrusion into the vacuum system can also impair brake booster function, compromising stopping ability. Confirmed by Dealer: Diagnosed and confirmed by Audi Reno Tahoe (Reno, NV) on April 9, 2026. Written estimate #XXX documents replacement of the water pump, pulley, valve, vacuum unit, hose, and tank — totaling $6,591.37 out of pocket. No recall or manufacturer assistance has been offered even though this is a known issue dating back to 2013. Warnings: On 4/9/2026, dealer reports that after a non related repair test drive the technician observed "Drive system malfunction ON during hard acceleration" as well as visible signs of coolant leakage. Prior to having the non-related service completed, I did not see any warning lights or receive a temperature warning. Known Defect — Recall Warranted: This failure is consistent with a documented defect across 2013–2022 Audi/VW 3.0T engines. A class action — XXX et al. v. Volkswagen Group of America, Case No. XXX— specifically names the 2020 SQ5. Despite known complaints, internal testing data, and dealer reports, no recall has been issued. I urge NHTSA to investigate and mandate a recall of all affected vehicles.

Vehicle experiences sudden, intermittent loss of motive power, severe engine hesitation, and stalling while operating at highway speeds. Diagnostic scans confirm fault codes P2015 and P0341, indicating a failure of the intake manifold position sensor and camshaft position correlation. These mechanical failures, combined with extreme carbon buildup on the valves, create a hazardous operating condition where the vehicle cannot maintain safe speeds in high-traffic environments. The manufacturer (Audi) has acknowledged the intake manifold failure—which is a known defect under an extended 120,000-mile warranty—but refuses to remediate the consequential engine damage (carbon buildup) caused by the faulty manifold and a previous oil overfill incident at a certified dealership (Chapman Audi of Tucson). Despite a 12-month documented history of seeking repairs for these safety symptoms, the dealership repeatedly failed to diagnose the manifold defect, instead clearing codes and returning the vehicle to the road. This systemic failure resulted in a hazardous operating condition that now puts the driver at immediate risk of rear-end collisions due to unpredictable engine stalling. By refusing to perform the necessary top-end cleaning required to restore the engine to a safe state, Audi is knowingly allowing an unsafe vehicle to remain in service. This represents a significant risk to public safety and a failure to address a documented powertrain defect that compromises vehicle control.

My 2019 Audi Q5 has 23,300 city-driven odometer miles. The vehicle has been serviced and maintained per the Audi Service Manual, based on months in service, not accumulated mileage. The vehicle has been garaged both at home and at work. The vehicle has never been driven off-road. When driving, an “All-wheel Drive: malfunction! You may continue driving. Please contact Service” warning message sounded and appeared on the instrument panel. The malfunction was diagnosed by Audi Honolulu and another Audi repair shop as a Shift Fork Unit issue and/or Quattro differential failure, which needs to be replaced. Audi has has a Technical Service Bulletin for a similar problem for the Q5. Audi Honolulu and Audi America refuses to provide a goodwill repair citing the age of the Q5. While the vehicle is 7 years old, a Shift Fork or Quattro Differential should not fail at 23,300 miles, regardless of age. I have been told by both repair facilities that the Shift Fork Unit or Quattro Differential could suddenly fully fail and seize causing a sudden loss of forward movement. I am afraid that if this happens at freeway speeds coming to a sudden stop could cause serious injury and if a vehicle behind mine slammed into me at freeway speeds a catastrophic or deadly accident could occur, especially at night or in inclement weather conditions.

What component or system failed or malfunctioned, and is it available for inspection upon request? - While on highway the vehicle loosed all Power indicating Electrical Malfunction How was your safety or the safety of others put at risk? It happened on I-35 Freeway twice putting me in danger of 18 wheelers around me. I am afraid to be in the vehicle even if they return it to me. Based on records this issue has been present on the car since it rolled off manufacturing. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes and Dealer has reproduced it and has the car with them for 5 Plus months. Have replaced many components and are not able to resolve it. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? South Austin Audi Dealer has been working with Audi Corporate Technical team and have replaced 5 parts to no resolution. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Electrical Malfunction - Red light flashing to pull the care over to the emergency lane but there is no acceleration - you are left to depend on whatever momentum is left on the car. Based on records this issue has been present on the car since it rolled off manufacturing. Based on records this issue has been present on the car since it rolled off manufacturing.

Title - Sudden Loss of Steering Control While Driving – 2018 Audi Q5 (Aug 2024) While driving my 2018 Audi Q5 at normal road speeds, the vehicle experienced a sudden and complete loss of power steering assist. A dashboard alert stating “Power Steering Malfunction” appeared simultaneously with an immediate and severe increase in steering effort, making the steering wheel extremely difficult to turn and effectively resulting in a loss of steering control. This incident occurred on a public roadway while I was transporting my family, including two young children (ages [XXX] and [XXX] ). The uncommanded loss of steering assist created an immediate and serious safety hazard and could have resulted in a crash, serious injuries, or fatalities to vehicle occupants and others on the road. I was able to bring the vehicle to a stop and subsequently to the dealership, only with significant effort and risk. There were no prior warning lamps, noises, reduced steering assist, or other symptoms before the failure. The malfunction was abrupt and occurred without any advance indication. The vehicle had approximately 39,000 miles at the time, which is well below what would reasonably be expected for a power steering rack failure. The vehicle was not modified or abused and was driven under normal conditions. Audi dealership confirmed failure of the electric power steering system and diagnosed the issue as a power steering rack failure requiring full replacement. The repair was completed only after the vehicle became unsafe to operate. The removed component may be available through the servicing dealer or Audi of America for inspection upon request, and I have retained all repair documentation. Audi of America was notified of this incident after the repair but declined responsibility. Based on subsequent research, I am aware of multiple similar reports involving Audi Q5 power steering failures. I am submitting to assist NHTSA in determining whether this issue poses a broader risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I

My dashboard VIN plate was destroyed when the windshield was being replaced. I’ve been trying to get Audi to send me a new VIN since October 23, almost 6 months ago. They assigned an executive case manager 2 months ago but that’s accomplished nothing. The vehicle is out of compliance with federal law without a VIN plate and I cannot trade or sale the car. Please help me.

The console is reporting: "Front left side marker light is defective. See owner's manual". This is a lighting problem that Audi seems to have covered by a previous recall but this VIN was not included in said recall: Campaign 97CB/NHTSA #16V642000. I have had this defection confirmed by my local service center.
