Was driving and service engine soon and reduced engine power loss came on. The car basically starting shutting down but I was able to coast out of traffic before it stopped completely. Turn it off, back on several times, until the lights went off then drove it home. I've replaced the throttle body twice and the gas pedal for the sensor located behind it. Went from happening sporadically to almost everytime I drive it. Can't drive 3 miles without reduced engine power loss coming on. Now there's about 155,000 miles on the vehicle and it's happening all the time. Needless to say, it's sitting on the driveway. I'm aware other customers are having this same issue from reading comments online. I don't understand why gm has not done a recall to fix the issue. Perhaps it can't be fixed.

My gmc's service engine soon light went on and I took into the shop. They stated that there is a fuel issue for the fuel cap and that the fuel tank needs to be replaced because it leaks. This is a manufacturers defect and this part should never "wear out" over time or due to the number of miles driven. Gmc needs to stand behind their vehicle and replace this part for free!

On thursday 12/27/2011 on my way to work pulled into hess gas station put my truck in park look up and I was rolling back... Look at the gear shift and it was in park but on my dashboard the truck was in 1st gear tried to pull it out of park by the hand gear and it kept rolling back and forth then it finally lock up in park but still on the dashboard it said it was in 1st gear unable to change gears, had to have my truck towed to where I purchased it from autoline in jacksonville fla. Found out the shifter cable pop in half had to have it replaced purchased the shifter cable and shifter assembly costing just for the parts over $200.00 at 292.00 labor I only had the truck 3 months and since they claim it was wear and tear it was not covered under my extended warranty I purchased. This was a very scary morning glad I was not driving it and pulled over to purchase gas that morning. What I don't understand is why is this considered wear and tear.....

While driving at approximately 65 MPH on the 405 freeway, the A/C was turned on and the engine died. Previously about 3 days earlier, while stopped at a traffic light, the A/C was turned on and the engine died. Following both incidents, the A/C was turned off and the engine was restarted without further problem.

2004 gmc envoy xuv dies when in drive and stopped for stop light, stop sign, etc. When the gas is applied, the car dies and I tie up traffic while having to shift to park, restart the engine, and then shift to drive and proceed through the intersection. It never dies while driving, only at a stop. I have had this car to the dealer numerous times and, because there is no "code" , they don't know what to do to fix it. The car also has a gas tank that is cracked at the neck and causes the check engine light to be on all the time. The dealership assures me that this is not a safety concern nor does the gas tank crack have anything to do with the engine dying. There is no gas leak but air does get into the tank causing the light to stay on. The throttle body has been cleaned and the entire emission system has also been checked and no one can figure out what the problem is. Dealership also says that the gas tank problem is quite common but that there is no recall..................why not?????? The main computer module was replaced and this has been happening since then.
