I took my car in to get the recall taken care of and they did something to my subwoofer system, it won't turn on. I left a message for Steve Younger and he never called me back! I will never take my car there again. In fact if I can't getting it working again, I will calling corporate and demanding a new system because when I dropped my car off it was working great.
