The only car that burned me bad enough to really be turned off by the brand was an Audi. As a point of reference, my wife's first Audi was a new D2 A8 V8, which was truly a great car for us. Her second Audi was a new B6 A4 which was such a lemon that it was a nuisance under warranty and ridiculously expensive to maintain after warranty. It was so bad that it totally erased the great experience of the A8. It drove great when it wasn't broken. I still appreciate the new Audis, but I won't buy one.
Just a few of the audi issues: New transmission at 11K miles, major oil leaks caused multiple times by failures in the PCV system under warranty. rear cam chain tensioner failure under warranty. After warranty, PCV failures costing over a thousand dollars (including cam seals, etc due to pressurizing crankcase with turbo boost), alternator pulley failure, dipstick tube broke off, right side CV axle failure. coilpack failures, valve cover gasket leaked. Hood release latch broke. Most interior surfaces were replaced under warranty, then peeled again after warranty. And the car was traded at 67K miles. It was not uncommon to try to move something and some plastic elbow or fitting would crack or break w/ minimal pressure.
Sorry, I was planning not to rant.
I had a lot of trouble with the early Ford RWD overdrive transmissions in the Aerostars, but that was one item that failed every so many miles and the van worked reliably for 50K+ miles between failures. The bad Audi was traded in with 67K miles, needing repair.
