2004 GMC Envoy Engine cooling Problems

“Speedometer does not work accurately. Check engine light came on randomly. Is currently out and I was able to pass emissions, hopefully it will remain out. Had to replace many parts including the heater core, thermostat and coolant. Now I am experiencing a problem with the fan of the car.”

“I bought my Gmc Envoy in january 2004 for approx. $42,000. This car has everything. After about 2 months of the purchase, my GPS went out and had been fixed twice. My brakes do not always work --sometimes they slip especially when I need them most -which is scary. Gmc said that they have heard about this problem before, but did nothing to resolve the problem. The engine stalls periodically. Gmc said they do not know why. The gas gauge and odometer do not work properly. …”

“I was driving in town and my speedometer stopped working at 0. The oil gauge is not working, pegged out at the max and my engine light is now constantly on. These events, particularly the speedometer not working, is a major safety hazard. Not driving at controllable speeds can lead to an accident and death. The parts and labor to fix this problem is $550. While researching this problem on the internet, I've found out that this is a common problem with Gmc's in this year. There should be a recall with the cluster unit on 2004 Gmc envoys. …”

“I purchased a used 2004 Gmc Envoy slt, with an extended warranty from grand prix auto group, hicksville, ny in august 2008. Soon after purchasing the car it stalled while we were at a red light. Immediately brought the truck back to the dealer and they said they fixed it, may I mention it never stopped stalling. Then the speedometer broke again. It constantly says I'm traveling 120 miles an hour. Once again, brought it back to the dealer, they tell me I need to go to a Gmc dealer, I do, they replace the information cluster and speedometer, had to pay a $ 300.00 deductible. …”

“Gmc Envoy SUV (4.2) inline 6-cylinder. Vehicle has stalled five times intermittently over the past six months. It stalls out when you begin to stop or start to accelerate from a stop or just while idling. Luckily it hasn't been when I was trying to pass or merge in traffic. The first time was around 23,000 and the second time 23,500. The next occurrence happened while it was sitting in a parking lot idling and it died after running for 5-8 minutes. I took it to the dealer and they said it was the throttle body that needed cleaning - done. …”
