I'll just give my 2cents....I moved from a 2001 Audi S4 to a G35coupe and i'm loving it!!! The Audi gave me nothing but problems!!!! I'm glad everything was covered under warranty!!! But after the warranty was over...That's when it all began..... I'll put it this way i took my car to audi/vw mechanic outside the dealership and he says audis are very "buggy" meaning they'll constantly have problems....In the service manual it says you don't have to change your timing chain till 120K well...come to find out Audi is actually in a lawsuit right now with hundreds of car owners whose chain has broke well before the 120K mark....Did i as well as others get a lemon....who knows....but what i do know is Audi's suck a$$...Sure they look good and are luxurious...but let's face....they're so common in Europe b/c they are the equivalent to a Ford or a Chevy here...Anyways....sorry for ranting off like that.....Can ya tell i don't like Audi's? Hahahah....Cruz if you want something with more power, etc...Get the new corvette or porsche...just don't get the audi.....save yourself the headache!!!

 

You must be looking at a different CR. Here are the real facts......red is good black is bad.

Model Predicted Reliability History CR Recommended
Murano Very Good Almost Perfect Yes
Titan Good Almost Perfect Yes
Altima Good Very Good Yes
Xterra Very Good Very Good Yes
Maxima Very Good Almost Perfect Yes/every year
350Z Good Almost Perfect Yes
A4 Good 2004 only rest BAD Lots of Black/bad No accept 2004
A6 This car has some of the worst ratings I've seen.

As far as the Quest and other Nissan's. The Quest is made by Ford and is the same as the Mercury Villager, that would explain the poor ratings.

The average ratings you were talking about are predicted reliability and not based on past performance for the most part. If you compare the Sentra to the A4 History, you will notice a LOT more black on the Audi.
