2018 AUDI A6 Complaints

Audi is unable to correct the recall repairs despite several attempts by us to schedule. Advised parts are no longer available and were not available during 2 previous attempts to repair.

February 27, at approximately 1:20am my vehicle caught fire while parked in the driveway after sitting for about 9 hours. The fire originated near the gas tank. The fire department was called, there is a fire report being conducted. Audi was notified.

2018 Audi A6 3.0T diagnosed a coolant leak due to water pump failure at less than 43k miles on March 27, 2024. In July 2023 (at less than 39k miles), the vehicle's thermostat was replaced due to a coolant leak. These are substantial failures in terms of risk to engine damage and cost to consumer, within a time and mileage period where a consumer should not expect these issues.

The main water pump failed earlier than expected at 48000miles. Dealer mentioned that water pump should not fail so early

Coolant leak, warning light signified an issue with the cooling system. Took vehicle to Audi dealership service department; they confirmed there is a big coolant leak with the coolant pump and thermostat. Vehicle inspected by Audi Sewell dealership for repairs. Symptoms appeared approximately 11/19/23, 2 weeks days prior to taking into the dealership. I had the oil changed at a non-Audi supplier); I informed service technician coolant warning light was on and service tech informed me vehicle was low on coolant. He replaced oil and topped off coolant on 11/19. Service light was no longer on; 2 weeks after the light came on again so i reported to Audi on 12/1/23 for repairs. Audi confirmed lose of containment of coolant.

The EPC light came on in my vehicle and I noticed I started to lose gas faster than normal. Took it to a shop to get diagnosed, they stated that my vehicle was under a recall (Recall #24DP). I called Audi and they said I do not fall under the warranty even though the website said 2016-2018 Audi A6 were under recall. They would not provide any help for me. My vehicle is showing all the signs of the recall. Sometimes the car will accelerate too fast and it is a risk for not only other drivers but me as well. It is just ironic that the same same problem for that recall is happening to my vehicle.

The contact owns a 2018 Audi A6. The contact stated that the EPC and engine warning lights were illuminated. The vehicle was taken to an independent mechanic and the contact was notified of an unstated recall. The contact called the local dealer and was informed that the repair was not covered under recall. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and the contact was informed about a buyback, but no additional assistance was provided. The failure mileage was approximately 52,000.

2018 Audi A6 3.0T, VIN [XXX] At 38,637 miles, Audi dealership diagnosed that vehicle requires water pump replacement due to water pump failure, causing vehicle to leak coolant. The vehicle has previously displayed a low coolant warning light prior to water pump failure diagnosis. My research has found that in October 2022, a class action suit was filed for over water pump defects. See: https://www.classaction.org/news/audi-defective-water-pump-class-action-includes-2021-2022-vehicle-models-with-3.0t-engines The suit looks to cover all persons or entities in the United States who are current or former owners and/or lessees of a 2013-2022 Audi S4, Q5, S5, SQ5, A6, A7, Q7 and A8 vehicles with a 3.0T engine. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

While driving at 60mph on the freeway, the glass sunroof on my 2018 Audi A6 randomly exploded/shattered. Glass shards flew into the cabin. There was no apparent “rock” or outside influence on the glass to cause it to shatter. The remaining glass remnants on the sunroof were angled up as if to suggest an explosion.

AT SLOW SPEED AND PARTICULARLY WHEN STARTING FROM STATIONARY, SUCH AS STOPPED TO WAIT TO TURN LEFT, THE CAR STALLS FOR 2-3 SECONDS, SUGGESTING THAT IT ISN'T GETTING FUEL. ONCE MOVING, THE CAR RUNS FINE. I HAVE TAKEN THE CAR TO THE AUDI DEALER TWICE. THE PROBLEM REMAINS. THE CAR ONLY HAS 14,800 MILES ON IT. IT'S BEEN HAPPENING SINCE I BOUGHT THE CAR IN MARCH, 2020.
