Audi A4 vs. BMW 3-Series Reliability Comparisons

You won't find Audi A4 or BMW 3-Series reliability information like this anywhere else. Actual repair frequencies, not just vague dots, to make it clear how much the Audi A4 and the BMW 3-Series truly differ in reliability.

These stats are promptly updated four times a year, to much more closely track Audi A4 and BMW 3-Series reliability as the cars age. Others tell you how reliable the Audi A4 and the BMW 3-Series were a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the Audi A4 and the BMW 3-Series have been recently.

8-speed shiftable CVT FWD
This Car is like a bad Girlfriend, Very Exciting, take her places, give her status, give her lots of money, Lots. And give her love, lots of Love ... and she just won't love you back. Two complete engine failures due to rings. And this car was maintained meticulously with 5w-30w Synthetic Oil . Complete engine Replacement at 89,000 miles due to piston ring failure in Cyl. #4. $9,000 Complete engine Replacement AGAIN at 116,000 due to Piston Ring Failure in Cyl. #2. This is a 2013 car. 3 years old. 2.0 Turbo Engine A new Audi crate engine is about $7,200 just for the engine. Then of course there is dealer labor and add ons. Just now quoted at $3,700 labor. You do the math. Here is the double cool part. A factory engine in a factory car has a 50,000 mile warranty. A factory engine installed by the Audi technician at an Audi Dealership, 12,000 mile warranty. If I was racing this car on the track I could accept those kinds of engine failure numbers. But I'm an "old guy" just doing average city and freeway driving. It appears I am not alone, http://www.telegraph.co.uk/motoring/news/9815860/German-cars-lose-out-in-reliability-survey.html Warranty Direct underwriters did the engine failure rate survey by Brand
