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.

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.

TrueDelta Reviews the Reliability And Durability of the 2015 BMW 3-Series

2015 BMW 3-Series Reliability And Durability: Cons
YearComment
2016 For anyone planning to keep the car well beyond the warranty period, "reliability" might also constitute a "why not." The tweaks made for 2016 appear to have introduced some rattles and minor electrical issues. I wouldn't worry too much about these. BMWs tend to be about average for the first four years, and reasonably reliable for up to six. Longer than that, though, and expensive repairs can happen. (Our latest reliability stats for the 3 Series.) This noted, the same can be said about every competitor save the Lexus IS and perhaps the Infiniti Q50 (which doesn't yet have much of a track record, and which initially suffered from software issues). We don't have data on the XE, but Jaguars aren't renowned for their reliability. With this, I'm out of "why nots." A champion in the premium compact sedan all-around, the 3 Series lacks glaring weaknesses. full 2016 BMW 3-Series review
