Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Belt Starter Generator failure rendered car undrivable -- power steering failed while in motion. Issue is subject to Class Action Settlement in USDistrict Court, Case # 3:23-cv-02291-RK-RLS. But this should have been a recall because of danger of Injury or Death. A recall would provide notice that the notice of settlement failed to provide. This failure happened to me on March 29, 2026. Dealer is not able to do the repair work in a timely manner.”
“I was driving my car would not accelerate on the highway and it almost caused me to get into an accident with my niece in the car. When I took the car to Audi this is what I was told my the service adviser. “Good afternoon. The technician has been looking into the vehicle and has found the cause of the issue. He has found the coolant water pump has failed internally causing coolant to leak internally into the vacuum system. This is causing the vacuum to be blocked for the turbo and thus causing the sluggish feeling when accelerating. In order to fix, the water pump and all compromised vacuum system components need to be replaced. It is a rather extensive job unfortunately.” My car only has a little over 45 thousand miles. Audi should be responsible to fix this problem because they sold this car knowing the water was faulty in these models. I recall should have been put out. I was quoted $6,000 to fix this problem.”
“At approximately 52,000 miles, on August 11,2026 (or earlier), my vehicle developed a coolant leak that was traced to a failed coolant shut off valve. The coolant shut-off valve failure allowed coolant to migrate into the vacuum harness, vacuum reservoir which contaminated the water pump. This resulted in the vacuum system becoming filled with coolant, compromising components that rely on vacuum pressure to function correctly. The combination of these failures — water pump contamination, coolant shut-off valve failure, and a coolant-contaminated vacuum system — points to a defect in the design or manufacturing of these components rather than an isolated or wear-related issue.”
