Front Suspension Wheel Bearing problems of the 1999 Audi A6

Takata recall I've had to replace a wheel bearing and axel 2x @ $550 each time. Car wouldn't align right, so I replaced the tires several times due to the wearing on one side. The calipers won't come off when changing the brakes and rotors. The automatic windows would randomly roll down sometimes after it would rain, and wouldn't roll back up for several days. I fixed the turn signal and cruise control, but the problems with those returned after a couple weeks, and while I was driving the under cover/protector plastic broke off all over the road because the Audi dealership apparently forgot to put it back on properly. This possibly allowed for the oil pan to hit the ground and crack, which a suspension problem was clearly part of that problem too. I took it in to see about a crack in the oil pan. They couldn't find it, but shortly thereafter, I drove to the movie store and when I got back to my car, it was no longer running. A puddle of oil was spilling out of it, and the the engine was shot. I had the car for about 2 years. I'm guessing that the problems stemmed from the what the car was recalled for.
