While on trip home from jacksonville my car ran hot at 62,000 miles while driving. No previous warning of any kind. After a lot of towing expenses and uncessary replacements of other parts to try and fix it , I finally had to again have it towed to dealer. There I was told that it was a faulty chain that comes from engine that drives the water pump to work correctly. Well, GMC knew of the problem . As I found out ,they had put an extended warranty on that part . No recall, no notification to owners that this could become an issue. I was on interstate 10 and had the car stalled in traffic I would probably not be here today. They are fixing the chain but now all of a sudden they are finding all kind of other problems while in the motor. I am trying to at least get my towing reimbursed . This is another example of GMC trying to cut corners instead of issuing recall to correct the faulty part. I am furious.
