“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.”Owner report · Fuel/Propulsion System · Feb 2026
“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.”Owner report · Engine · Mar 2024

“The main water pump failed earlier than expected at 48000miles. Dealer mentioned that water pump should not fail so early”Owner report · Engine · Dec 2023
“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.”Owner report · Fuel/Propulsion System · Oct 2023
“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.”Owner report · Engine · Oct 2023
“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.”Owner report · Unknown Or Other · Feb 2022
“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.”Owner report · Fuel/Propulsion System · Mar 2020
“When making a u-turn after completing the turn portion the car fails to accelerate. It is as if the vehicle can't figure out what it is supposed to do. The failure is for a short time but absolutely nothing happens when the accelerator is pushed then suddenly the vehicle again accelerates. This has happened to me 4 times in the past year. Discussed with dealer and was told that is "the nature of the car" and the service tech said it usually happened to him when turning in an intersection and he would "floor it" and the car would jump.”Owner report · Fuel/Propulsion System · Dec 2019
