Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Issue with poorly engineered water pump. My water pump went out due to a small plastic seal malfunctioning and allowing coolant to expel from system. I am fortunate I learned of the issue upon starting my car and could immediately take care of it, although leaving work at 9pm, long after everyone has left and with no automotive shops open made it difficult to take care of. Upon talking with an independent Audi/vw specialist and doing my own research I came to find this was an incredibly common problem. My car had only 35k miles on it and was 1 month out of warranty when this occurred. …”

“The car burns too much oil, need to add 1 quart every 700-1000 miles. There is no leak but the oil burns and you can see the exhaust pipes are black. It seems this was a problem in 2011 4 cylinder audis and it was addressed by Audi.”

NHTSA complaint #11289275, filed 2019-12, 85,000 miles

“The engine failed while I was driving. The car did not show any warning lamps, messages or other symptoms, it just jumped and died. I had the car towed to my mechanic. The mechanic thought it was the starter, but then realized the chain had broken and it hit other parts of the engine, including the pistons catastrophically. The engine is not reparable. My safety was a risk as the car died on a busy road. Audi has asked that I bring the car, at my expense for them to inspect, without offering anything. I have a letter from them indicating that they will not help. …”

NHTSA complaint #11447143, filed 2022-01

“Spark plug for damaged due to oil seeping into it. This could lead to overheating of engine or cylinders getting damaged potentially leading to vehicle malfunction when I drive. Audi inspected the part and recommended to reseal the top of the engine. There was a warning for check engine which led to identifying the problem”

NHTSA complaint #11643290, filed 2025-02

“The vehicle has an oil consumption issue whereby I top off the oil in about every 400 miles. The dealership indicated that this is a known problem with Audi. The issue first started with warnings that engine is overheating and with further warnings that oil level is low”
