2004 GMC Envoy XUV Engine cooling Problems

“I have a 2004 Envoy Xuv with a cracked exhaust manifold. My mechanic said he has seen a lot of these on the 4.2 and tells me it is due to bad design. Gmc won't fix it unless I give them about $1,000.00. Exhaust manifolds almost never cracked in the past. Please insist they help us like we helped them.”

“I purchased a 2004 Gmc Envoy Xuv and have several significant problems with this vehicle. After researching it seem others have had the same troubles. Since we owned the vehicle, the rear window is found down and noone was even in/near the vehicle. It continues to work but still will go down by itself. A year ago I had to replace the fuel tank, this was right after we took it in for inspection on a recall of smelling gas fumes while driving and possible corrosion in fuel lines. Of course the fuel lines were not corroded so we were told. …”

“I have a 2004 SUV xlt. I bought my car with 400 miles on it. I had the gas tank replaced early on. Went back to Gmc b/c they had not installed it properly. I've had both front and rear sway bars replaced and both knock sensors replaced. My middle window decided to quit working and I haven't gotten it fixed because the guys at the Gmc service center said they couldn't imagine what it could be and they would have to charge me $100 for a diagnosis!! My radio/cd player is only half lit up and stops working when it gets too hot from playing a cd... …”

“My Envoy Xuv (8cyl) has engine trouble, which Gmc says is normal. It occasionally has extremely rough idle, more times than not, it hesitates as if trying to decide if it'll stall out or not. Usually this happens when attempting to resume driving after sitting at a light or after other complete stop. I feel that this one day may get me rear ended or t-boned by another car. Sadly, I noticed this since the first day I drove it off the lot brand new.”

“2004 Envoy Xuv, impeccably maintained, had *no* response to accelerator as I made a left turn at a light across oncoming traffic. Service engine soon and reduced engine power lights illuminated on dash. Was fortunate not to have an accident. Pulled to side of road. Turned off engine. Restarted, and it ran okay but the service engine soon light reappeared. Drove another 35 miles with light on. The next morning it had re-set and the light is gone from the dash. How in the world does GM expect us to be able to replicate such incidents for a tech to fix? Such failures will eventually kill someone.”
