2004 GMC Envoy XL Engine cooling Problems

“I purchased a 2004 envoy with 18,000 miles in the summer of 2006. Beginning in january 2007, my 3 year old son let me know that he was cold while riding in the back seat and begged that I turn off the air. Turns out that the vent in the back of the car was blowing ice cold air on my son. The temperature outside was approximately 10 degrees. I called and scheduled a time to take my car into the dealership, as it was still under warranty. …”

“I heard a clicking noise from under the hood and after pulling off the cover plate for the engine exhaust manifold I saw the manifold was cracked. At idle speed fumes get inside vehicle. Repair has not been made so old part is available. Upon research on the internet there are numerous other complaints of this problem. I sent an e-mail to GM and someone called and said they need more people to report it to get something done. I believe it is a safety issue because of the fumes and possible fire hazard.”

“Hello, hope you can help myself and other persons from not happening. I came home from work saturday, and parked in the garage as usual. After being home and watching some tv I know for sure was 2 in a half hours. My wife asked of me to go to the garage to get some ice cream, we have a freeze in there. I walked in the door and couldn't believe how hot! It was in there it wasn't a hot day at all to make the garage sizzle. We have a thermometer gauge in there and believe me it read 100 . I was shocked! …”

“Engine, check gadges light appears, SUV stalls, radio lights and steering lights keeps failing. I have taken my 04 envoyxl into the dealership over 7 times for the same problem in which they have not yet been able to fix/resolve. My envoyxl check engine and check gadges lights keep popping on and the vehicle continues to cut off/stall the dealership has not yet fixed the problem, I have taken the SUV in over 6 times for this problem. From 2004 until now 2007 the problem continues. The lights on the dash board keeps going out. …”

“For the last few months the check engine light would come on and go off after a few days; we took it to our mechanic who ran a diagnostic and they said there is nothing wrong, probably a faulty sensor, not harmful. So, last night while driving, using cruise control and on the interstate my speedometer stopped working. When I came to a stop at an exit I noticed the speedometer was reading 42 MPH but I was at a complete stop. I do not even want to imagine what might have happened should it have begun to work while I was doing 60+MPH while on cruise control!!! This is extremely dangerous! …”
