2 Radiator problem of the 2005 GMC Envoy

Failure Date: 08/22/2016

I had three cars in front of me stopped. I did not see any breakl lights and I hit the car in front of me pushing the other cars to hit each other. My front end of my car was severely damaged bad enough to damage the radiator and destroy my ac unit. I'm not sure what else was damaged. It sent the person in front of me and myself to the emergency room. " my air bags did not deploy ". My vehicle was moving on a city street.

3 Radiator problem of the 2003 GMC Envoy

Failure Date: 05/18/2007

2 complaints noticed enginee running hot, added fluid to radiator, near empty. A couple of months later, same thing. 3 months later, during oil change, mechanic indicated while doing checks that the radiator fluid was low. Told him this was the third time, he added fluid, pressure checked radiator - no holes or leaks. Seems to be evaporating. Air conditioner blowing hot air (excluding the fact the panel with ac controls quick working a loooonng time ago). Took in to dealer for repair. After $600 and all day visit with dealer, the piece broken was the size of a 2"-4" block of plastic. This little piece just quick working, it was referred as a control switch of some sort under the dash board. Sounded kinda hokey to me - I can imagine a compressor going out and you do not have cold air - the name of it escapes me - but the mechanic did indicate there was some sort of technical report out there on it as well. Just found out from husband the name of the piece - the actuator door quit.

4 Radiator problem of the 2004 GMC Envoy

Failure Date: 03/02/2006

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.
