Noticed that the AWD did not work (rear wheels only) when the car got stuck on snow. Brought the car to the first dealer, who insisted that nothing was wrong with the car as the computer says "it's OK". Obviously not having AWD was not OK for me. Dealer replaced transfer case because the AWD system was not working. First dealership we brought the car to had claimed there was no problem because the computer said "it's OK"

Loud screeching noise from front left side. Turned out to be a bad bearing. While replacing the bearing, I was informed that my brakes had about 1% (front) and 3% (back) left, so I had all four brake pads replaced as well. Was hearing another noise when turning left. High pitched noise that would repeat, kind of like a broken record. When doing a full left turn, such as in a circle, the sound would be steady. Loud noise still there. Asked them to take another look. They found that the back plate was still rubbing on the rotor. It had not been properly adjusted the first time the noise had been noticed and brought in for repair.
