About a month a ago my 2003 yukon xl all of a sudden would not drive over15 miles an hr in rush hour traffic. I took the truck to the shop to have diagnostics ran. I was told it was the battery. The truck ran for about a month then all of a sudden the battery was back dead. Returned the truck back to the shop another battery was put in. It's been about another month. This time I was driving from miami to jacksonville and the truck lost power 100 miles outside jacksonville on I-95 north. It had all power just would not crank. Had it towed to the shop now I'm being to there's a problem with electrical.

We were driving up in the mountains and we lost power briefly to the engine. The lights flickered and the dash board went out. Then the loss of engine power came on and the stability/traction came on too. This has happened weekly for the last two years. This last time was alarming since we were coming down a mountain in a storm and could have been stranded up there with no running vehicle to keep us warm. This needs to get a recall or investigation going on these vehicles. If you google this issue you will see that there are hundreds if not thousands of people that are affected with this issue. It will kill people if they expect to have power to get through an intersection fast enough and the vehicle gives out on them.

Driving 65 MPH on the highway and all of a sudden my car loses power. This is very dangerous! The dash says reduced engine power. Engine light comes on. Codes for the problem p0120, p0171, p0174, p0300, p2135. I got everything done that was suggested the codes are gone and it's still happening!! Not sure what the gmc dealership is up to but they don't have a clue to what's causing it or how to fix it!

Reduced engine power, stability system disabled

Filed Feb 7, 2011 · Driver assistance · 140,000 miles · IL

For the last 2 years I've had a problem with the stability control / reduced engine power. The problem can occur anytime while driving or even after it has been sitting. I must stop the vehicle and turn it off several times for it to reset before I can continue. I've had the vehicle in the shop for repairs at the dealer, they can't seem to fix the problem. After several visits to repair shops and spending nearly $2000 on repairs it still has the same problem. This needs to addressed as a failure and dangerous situation by g.m. The vehicle is a 2003 gmc yukon denali xl.
