SUVs GMC Yukon Yukon "Reduced Engine Power message"

I purchased my 2006 Yukon last September 2005. I now have 24,000 miles on it. Over the last month I have had it into the dealer three times for the same problem. The problem is that while driving the vehicle it will suddenly lose almost all power. The Information Center will display the messages: "Stability Control Disabled", "Engine Power Reduced". And the vehicle will not go over 20 mph on a level surface and bearly 3 mph up a moderately steep hill. Each time I have had it into the dealer for repair they have beeen stumped by what the cause of the problem is. They said that GM/GMC told them that "GM is aware of the problem but does not have a fix for it at this time". How can a manufacturer sell a vehicle that has a defect and not have a fix for it? When the power goes out in a busy intersection or on a highway this is a major safety issue. Has anyone else experienced this problem. Thanks, Steve

Update...the day after my last post I was driving and my Yukon just shut down completely. I have looked on the internet and have found A LOT of people with the same complaint. I called GMC and filed a complaint...told them that this should be a recall since it's such a serious saftey issue. Didn't get much sympathy from them and am very upset at this point. I'm making payments on a vehicle that isn't safe to drive. It's sitting in the shop now...noone seems to be able to agree on how to fix it. If anyone has any further info on fixing this problem PLEEEEAASE let me know! Thanks! Stephanie

Things have gone from bad to worse with my 2003 Yukon XL. You need to be CAREFUL!! Mine was fine for a week and then went nuts again with all the kids in the car. Mine was in the shop for a week...ran fine for a week and then died again. Seems like whenever they mess with the wires it behaves for a little while. Dealership is NO help...GM is NO help...I have no idea where to turn at this point. I have a beautiful vehicle...sitting in the driveway, can't use it. GM and the dealership didn't seem to give a damn that this is a MAJOR safety concern...in fact when I called the dealership this morning I was so upset I was crying...the manager said that he "didn't like the way I was speaking to him" and said there was nothing he could do for me. I wasn't even letting him have it! I am SO fed up and confused. I even went to a FORD dealership today to see what they had that actually ran and stayed running...only found one SUV I liked enough to test drive...but all I did was bring it home, park it next to my Yukon, and make fun of it...I hated it...I just want my Yukon. If you find any further info on this please let me know. There are several TSBs regarding this issue but GM didn't seem overly impressed with that either. Hopefully someone will be able to solve this problem. Stephanie

Don't pay huge money for diagnostics...please read!!!! I finally found someone that fixed my YXL and fixed it right...The problem is the ground wires. My mechanic tightened one that he found loose and the other one the clamp was messed up so the ground wire was flopping around and not making a good connection. When he touched the ground wire he could hear the fuel pump going on and off and other things making noises. It was a $3 dollar clamp that fixed it...too bad I spent almost $2000 on diagnostics with the dealership that was trying to tell me I had a bad transfer case module as well as a bunch of other BS and another mechanic before I brought it to this guy. Make sure your mechanic checks all the grounds (I didn't know that there's more than one) and tightens them as well as making sure the clamps are in good condition. My clamp was broken causing a bad connection. So...it's a $3 part that caused this hellified problem! I'm just glad to have my vehicle back in good running condition...no thanks to the dealership or GMC!

Just wanted to let you all know that the last repair I posted about seems to have really worked. I was nervous for a while...waiting for my vehicle to die again but so far so good. (I'm probably going to jinx myself by writing this..lol.)
