Two problems related to door have been reported for the 1999 GMC Sierra. The most recently reported issues are listed below.
I have experienced excessive wearing of the front brakes, which has resulted in the rotors being replaced first, then the pads replaced 2 weeks later, and upon replacing the pads the new rotors required resurfacing. Since then after driving approx 5k miles, I was told that the new pads are appox 40% worn. I required the right front balljoint to be replaced when the rotors were done. When applying the brakes & hitting a bump in the road, the brake pedal goes down to the floor and has a complete lose of braking. It failed the annual inspection, due to a leaking donnut gasket. The tailgate squeaks & rattles, and appears out of alignment. The front driver's door creaks requiring repeated greasing. There appears to be excessive wearing in the front end and braking system, as well as excessive creaking & noise from the rear area of the truck, tailgate, and driver's door. I have been met with continued resistance and lack of answers from both the mfg and dealer. Any help or information would be appreciated.
One of the doors has an air noise. Yh.
