“My vehicle is leaking coolant. Every 8-10k miles it goes below normal level in reservoir . There is a distinct odor of coolant each time I get out of the vehicle. I have had Audi look at it 5 times. They confirm the coolant levels are low and they refill it saying they can't find a leak. I am concern that this is a fire hazard.”
NHTSA complaint #11394694, filed 2021-02, 23,000 miles“While driving on the highway, there was a message that flashed on the dashboard about the coolant system, within a couple minutes, I felt like the car was shutting down while going 65 miles per hour. So I pulled over on the shoulder of the Turnpike Southbound in Miami. This cased a great safety problem for me, as this happened while I was driving on the highway then I had to be on the right shoulder of the highway and had to call for road ranger. …”
NHTSA complaint #11420291, filed 2021-06“I have been trying to register my vehicle in California for several months, however, in order to do so, I need the car to pass SMOG.

A short time later, the fuel gauge completely stopped working. I took it to an authorized Audi repair shop that told me the issue was related to a the Fuel Tank Sending Unit . That part was replaced by the repair shop, however, the issue persisted. …”
NHTSA complaint #11703360, filed 2025-12“I have been an Audi A4 owner for more than 10 years. During that time, I have had 2 incidents where I could have easily been killed as well as injured or killed passengers in oncoming vehicles. The latest was this morning on March 23, 2022. The other was nearly 10 years ago. My personal investigation has led me to a conclusion that I have not yet seen anywhere else. In both cases, I am trying to get into a heavy flow of traffic. I know that I will have to gun it to get up to speed. For that reason, I have one foot on the accelerator and one on the brake. …”
NHTSA complaint #11457955, filed 2022-03“The fuel level sensor that is built into the gas tank, sensor #2, has failed and I only had 30,354 miles on the car at the time of failure. Audi Birmingham, in Birmingham, MI, confirmed the failure via a diagnostic test.”
