2004 GMC Envoy Owner Comments

problem #7

Envoy 6-cyl

  • miles


Low engine power light comes on and vehicle shuts down. Sometimes you can restart it with no problems. Now it sputters and has very little power. If you turn on anything it makes it worse. It surges and stalls. It chugs along until you turn off as may electrical items as possible.

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 deductible. This was in March 2009. Driving the other day October 2009 and the speedometer once again says 120. Get pulled over, get a ticket for a broken speedometer. The officer was aware I was not traveling at that speed, and even when I tried to explain, wanted to hear none of it. So now here I am again, broken speedometer, engine that stalls often and a summons to boot. I need help and I don't know where else to turn the dealerships are of no help. Jacqueline king

The contact owns a 2004 GMC Envoy. While driving approximately 45 mph on normal road conditions, the contact rear-ended the preceding vehicle. There were no damages to the vehicles or the occupants. He pulled over to the side of the road and noticed smoke suddenly appearing from the front end of the vehicle. Immediately, the passenger compartment became engulfed in flames. The contact safely exited the vehicle. The police and fire departments were called to the scene and a report was filed. The vehicle was completely destroyed and towed to a collision center. The insurance company was notified; however, the cause of the failure has not yet been determined. The VIN was unknown. The failure and current mileages were 75,000.

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 Envoy. GMC should try to prevent deaths that their products may create.

: the contact stated the vehicle started shaking prior to stalling while driving on the freeway at any speed five times. On each occasion, the check engine light illuminated on the dash. The vehicle has been to the dealership each time. On every occasion the gauges were cleaned and the oxygen sensors were replaced. The problem persists.

First of all my odometer gauge stopped operating. It remained on zero miles while I was driving the vehicle since November 2005. The whole dashboard cluster had to be reinstalled. Secondly; the service engine soon light began popping on and the Envoy was driving rough. I found out from a GM dealer that the clutch fan froze which caused the water pump to break and the radiator to over heat burst the radiator hose and spew out and leak all of the water and radiator fluid from the radiator. The Envoy is now not drivable. I have only had this 2004 Envoy since November of 2003.
