Electrical problems and door problems - I bought my Blazer when it was 2 years old with 8300 miles on it. With about 13000 miles on it the vehicle would not stay running and the battery gauge was under 9. I got the vehicle started and drove to the dealership. They replaced the alternator. They would not cover a loaner or rental since I was able to drive the car to the dealership. If I would have had it towed they would have covered a rental. 2 weeks later same problem repeated. Brought it back to dealership and they found the ground wire off the alternator was not properly tightened to the engine block. Again they would not cover a rental car since the car was driveable. That fixed the problem. With about 17000 miles on it and 2 1/2 years old noticed rattling noise coming from drivers side front. Noticed that the drivers side front door was sagging. Brought vehicle to dealership and again they would not pay for a rental or loaner. Problem diagnosed as door needing new bushing and center pins for the hinges. They had to order the parts and I had to bring vehicle back. Again they would not pay for a rental or give me a loaner. I had a 1/2 hour discussion with service director for the dealership and finally gave me a loaner. I called chevy about the problem with the doors and they don't find that out of the ordinary for the vehicle to need new pins and bushings with only 17500 miles on it. The 3/36000 warranty is up in two months and I will be getting rid of the vehicle before the warranty is up before something else breaks on it. I will never buy another gm vehicle!!.
