Based on other reviews, I was a little leary about taking my '08 Envoy to Jack, but a friend of mine suggested giving him a shot, so I did for an electrical issue that I was having difficulty fixing myself. He quickly re-established a wiring connection that he discovered had become loose, so I was initially pleased with his work.
A few weeks later, however, I took it back to him for an issue that I was experiencing exclusively when accelerating from a stop to no more than 5 mph. About an hour after I dropped it off, he told me that he had driven it about 15 miles - a whopping 15 miles without encountering any problems with its acceleration. He proceeded to charge me $60 for his time, and as soon as I drove it off his lot, the issue presented itself again. And when I got it up to higher speeds, not only did I notice that the tie rods now seem loose, but at least one of the wheel bearings is making a grinding sound. When I started a conversation with him about these new mechanical issues, he refused to even talk about them. read more
