Reliability is a tough thing to quantify. Some people think reliabilty means they buy a vehicle, and never spend another dime on it. Others correctly understand that maintenance is part of the total cost of ownership. Mine has been reliable...I trust it enough to embark upon a 500 mile journey, late at night, through the uninhabited wilderness that is called Michigan's Upper Pennisula, and I have. BUT...its / was bone stock. You start making changes to things, like giant tires, suspension lifts, superchargers, etc. and you are pushing things outside the envelope of "design intent"
I get ticked when I hear people complain about different makes, or American vs Japanese, etc. when blindly categorizing them is a logical fault. Sure...bad mouth your Ford, that you or a previous owner have done NOTHING to to maintain, and praise the Toyota that has had a full maintenance history. Or, Slap some 35s on a Jeep, then start bitching that the wheel bearings are shit. Guess what genius, the 35's are CAUSING the wheel bearings to be shit. People expect that vehicles are built to last through every imaginable idiotic thing they do to them, and they are not. They are built to a set of specifications, determined by marketing who uses focus groups. Same with aftermarket parts...I see it on the forums all the time. They will take something and use it not as the manufacturer intended, it breaks or otherwise does not perform well, and they bash it all over the internet. Well, its their own damn fault. The customer is always right, my ass. Whoever said that obviously never worked retail or manufactured consumer goods.
That is one of the reasons I like this forum, is that there is less of that bullshit around. The group that is here tend to be a little older, a little wiser, and use some logic and reason.
Anyway, I'll get off my soapbox. I do have to say that I'm sorry to those who've struggled with Audis. I have a '12 Q5 that has had service performed on it as the manual suggests, and its been a wonderful little SUV. I bought it new, its comfortable, quiet, good on gas, looks good, etc. Sorry you all haven't had the same experiences.
