Piston ring defect and blew from over oil consumption. All years from Audi A4 2012-2019 recall law suit but they did not include 2015 which all years and models have same piston ring manufacturer defect it blew on me while I was driving home. Lucky I was in neighborhood and not on highway very unsafe.

The engine had catastrophic damage. I was driving, full oil, and the engine just died. The mechanic said the engine was destroyed and believes it was a manufacturing mistake.

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. ABS SYSTEM and Brake Actuator that is failing or defective. Vehicle was taken to the dealer but was not repaired.

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 Audi/VW shop says they replace 4-5 of these pumps per week! it clearly is a major issue, especially since a car cannot function and is dangerous to operate without the cooling system. I was very upset that the Audi brand would allow a known problem to continue, as it does not seem like a 'luck of the draw' part malfunction.

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 Audi and it was addressed by Audi.
