Problem one the car was burning through a quart of expensive oil every 300 miles. Took it in, dropped the engine, changed all pistons, removed crankshaft oil seal, faulty high mount brake light, pressure regulating valve all replaced. Car was accelerating with and without hesitation, but dealer duplicated the occurrence and said they fixed. One month later, car smelled like gas and was taking off on it's own brought back dealer could not duplicate. Very bad smell of gas and rapid acceleration -dealer removed engine again replaced all valves, diagnosis purge valve stuck. Suspected injector seal.replaced 4 injector seals, smell persisted.replaced intake valve, remove and replace purge valve assembly. Pistons have all been replaced, engine has been completely removed twice, and the transmission is still jumping and the car accelerates by itself.Audi refuses to recognize the problem, I have only 1200 miles left on warranty. I have only had this car 7 months and am afraid to drive but Audi offers no options-I asked for extended warranty on the engine and they said no. I have the car in my possession with the acceleration issue and periodically smells of gas. I drive 3 children to and from.

Car brought in for misfire condition that resulted in power reduction/hesitation while driving. Dealer detected faulty injector. Replaced injector and engine was still malfunctioning. Dealer then removed cylinder and observed piston ringland damage. Vehicle was starting to exhibit excessive oil consumption problems. Either faulty injector or piston ring defect is suspected to cause damage. Looking into remedies through arbitration or other means as Audi is aware about (I.e. undersized rings / pistons). I will retain all suspect parts as Audi will not honor under warranty terms and independent shop will be performing repairs, and can be made available for further investigation. Excessive oil consumption is a known issue with Audi usa. The manual states that normal consumption is up to 1 quart for every 1000 miles. Per Audi's recommendations, you will burn 10 quarts of oil before you need an oil change. That engine holds 5 quarts when not leaking it through rings, reducing anti-knock rating of fuel during combustion. I believe this a significant safety hazard as engine seizing could unexpectedly occur due to defective components. I believe a class action lawsuit is inevitable.
