Freeway Chevrolet

I moved here from Wisconsin and got a recall for my Silverado. Something to do with the brakes on vehicles that were in saltly road conditions. Not to much before recieving this recall I had taking my truck to Dana tire and auto in chandler and was told it was in excellent condition for the mileage, because of the maintenance that I faithfully have done, and that at this time other than the L.O.F. that it needed nothing. 90,000 miles. I go to Freeway with approximately 91,800 miles on the clock for the recall from chevrolet and when I go to pick it up am informed that there are 6 major problems on my truck and basically it is not safe to drive. I said really, 1800 miles ago it was jsut fine and now it is a death trap. The service writer backs up saying he will recheck with the mechanic. Trying to shift blame to him. I just said thank you, but no thanks and left. Hind site being what it is I should have gone to management but did not. I have since e-mailed the general manager, on another subject, and the response I got about that e-mail told what he would do to help me with anything. Nothing!
