Engine Belts And Pulleys problems of the 2005 GMC Envoy

First the engine started making noise and the engine light came on, the dealer replaced a belt for 200. 00. Secondly the gas gauge stopped reading fuel levels, dealer stated that the sensor was dead and would cost 300. 00 to replace. Next the engine died in the middle of the street. The vehicle will not turn over and the engine light is back on. Also they had a sunroof installed for me. A week after purchase the sunroof started to open and close even when the car was shut off, it was repaired but now I am having the same problem again.

- the contact owns a 2003 GMC Envoy. The headlights, dashboard, and tail lights flashed randomly at any speed, this failure started in October of 2006. The weather and time of day were not factors in the failure. The dealership said that the failure was normal. There were tsbs for the failure, as well as for several others. The fuel neck had been replaced twice due to a design change. The seal around the licenses place holder came loose and had to be replaced. The brake pedal was squeaking, the contact took vehicle for service on three occasions, and replaced the serpentine belt twice, an airbag sensor, the rear wiper arm, the oxygen sensor twice ,the first time at 7000 miles. There were cruise control failures, when the contact tried to accelerate it hesitated and then surged. The weather stripping on the rear doors has been repaired three times. The abs would skip on a bumpy road and would not engage. At one point the contact could smell fuel in the passenger compartment and vehicle had very poor gas mileage, the dealer stated that there was nothing wrong with the vehicle, but air valve became stuck and would not close. The rear door hinges squeaked. This winter it won't go to full voltage until a minute elapsed after the vehicle has been started. The original failure mileage was 3829, and the current mileage was 23700. The brakes were inoperative, the belts squeaked, there was a problem with the abs, the air bag light illuminated, the cruise control didn't work properly, the rear wiper would only wipe the middle of the back windshield. A new fuel neck was installed. Updated 03/15/07.
