I bought a pre-owned Audi Q5 from an Audi dealer. At purchase I was told this car had one of the best engines and transmissions Audi made. Unfortunately I didn't do more research because their 4 cylinder engines are notoriously terrible. I have put ******* km's on the car since it was purchased from Audi with regular maintenance and now less than two years later the engine is fried and even though it's a common problem with Audi's, Audi Canada says they won't do anything to help because I'm the second owner and it's high mileage (remember I bought it from them!). Also had to replace the air conditioner, Ac joints, and have work done on the transmission. This car has been nothing but problems from the start. I would recommend anyone that is buying to steer as far away as possible from Audi. If you are leasing I'm sure it's different because most of your problems would be covered. But if you are buying used from them BUYER BEWARE. Also, lets not forget that they charged me almost $1000 to 'diagnose' the issue I told them it had because my other mechanic had already done it.
