Hydraulic Power Assist Steering System problems of the 2004 GMC Envoy

We complained about the transmission slipping at 33,000 miles and take it back to the dealer they say the checked the problem and replaced an electrical component, at 50k while my wife was driving on the highway at 65mph lost the power train. After much discussion and three weeks the dealer finally agreed to fix for 500 vice 3300 which they wanted. A week later the transmission is slipping again and now we lost power steering and the gas needle stopped working. I have left messages for the service manager at wiesner GMC in conroe TX and they have not returned any calls. I am now taking the vehicle to a different mechanic to tried to get it repaired.

The consumer complained about a power steering problems. There was a constant squeak in the steering even while the vehicle was parked. She said there was a popping noise while turning right or left. The consumer also heard the popping noise while going over speed bumps. The squeaking noise began as soon as the vehicle started. The service dealer replaced the power steering belt, power steering gear, a link and bushing, and the drive belt. Also, the dealer adjusted the power steering pulley. This did not remedy the problem, so they replaced the entire power steering pump. However, the problem recurred. The dealer thought it may have been something in the front suspension, so they replaced two stabilizer links. This still did not remedy the problem. Updated 11/29/05.
