Four problems related to engine cooling system have been reported for the 2005 GMC Envoy. The most recently reported issues are listed below.
I have a 2005 Envoy, today I was driving going the normal speed and got to a stop sign all a sudden the truck started reving up on its on and then would stop. Then I began to give it gas and to my surprise it did not have enough power to get up a hill. Minutes later the truck began to move as if nothing was wrong. I have onstar so I called for a diagnostic check, they stated that the cooling system needed to be checked , the antifreeze may be low and can effect the way the truck is performing. Well after going to the gas station to purchase the antifreeze then I start the truck and it begins to rev again on its own and suddenly I can not move. . . I had to have it towed to the dealer. . . . Is there a recall on this . . Im afraid to drive thi is dangerous. . . . I have young children. . . . . . Someone please advise. . . . . . I have never experienced this before. . . .
The contact owns a 2005 GMC Envoy. The contact stated that the fuel gauge displayed an empty reading after refueling. The fuel gauge began to display a normal reading the following day. The failure recurred intermittently. The vehicle was not taken to have the failure diagnosed or repaired. There was an investigation under NHTSA action number: dp10001 (fuel system, other:storage:fuel gauge system) that may be related to the failure. The contact also stated that one of the settings for the fan stopped functioning. The vehicle was taken to an independent mechanic where the contact was informed that the wiring harness for the blower motor was melted. The vehicle was repaired. The failure mileage was 89,980.
On 1/31/2011 my 2005 GMC Envoy showed my gas was down to a quarter of a tank. I stopped to fill up before a snow storm came in and put 16 gallons of unleaded fuel into my tank. Immediately after my gas gauge went to empty and my gas light came on. It went up to a quarter of a tank and then went back down again. It is still showing empty, with the gas light on, and I know it has a full tank of gas.
I have owned my 2005 Envoy xl since June of 2006. Once, I passed 36,000 miles, I started experience lots of issues with my vehicle. I started hearing a knocking noise in the rear when I would turn on the ac and the steering was off somewhat. I had the steering fixed for around $400 but the knocking was going to cost around the same amount. Less then 10,000 miles later, the knocking noise is more persistent and is related to issues with the fuel pump. My gas hand will move to empty when I fill the tank up and will not move forward for days at a time. Today, my kids are complaining about the ac not working in the second and third row seats. Everytime I turn the corner it seems as if there is another problem with my vehicle.
