Oh my, another bad review from me due to poor service!! I waited for two hours while the service department tried to figure out where the loud squeal was coming from near my seat. When they finally came to get me, they informed me that they had to order a part and would call me. Nearly two weeks later, I haven't received a call, so I called them and was told that the part was there. Then when I asked for a Saturday appointment to get it fixed, I was told that it had to be during the week.
