GMC Yukon XL 2500 stalling problems

Filed Dec 24, 2015 · Engine · 80,100 miles · VA

While traveling at highway speeds the engine stopped working / stalled. Shifting to neutral and trying to start the vehicle was not successful. The vehicle without the assistance of power steering or power brakes had to be carefully stopped . This was extremely dangerous! After looking at an on-line forum, the vehicle with the 8.1 liter engin had some vehicles recalled with a cam lobe sensor fault which causes this to happen. After contacting the dealer, they told me that my vehicle was not in this recall. However, when the vehicle was new, they had already replace the same part when the vehicle was 3-5 months old. I questioned them as to the replacement part as the first part only caused the check engine light, not completely disabling the engine. It may be they replace the factory original part with a part which was defective and covered by the recall. In eather case, a engine on heavy duty vehicle which quits and disables the normal brakes and steering is extremely dangerous.

Since november 2008, my 2003 gmc yukon xl 2500 has had episodes where the service engine light comes on and the engine goes into reduced power mode. In this reduced power mode, the vehicle will reach a top speed of around 25mph. I have taken it to numerous gm dealers to fix the problem, and they have replaced the throttle body assemble and wiring harness multiple times and the problem keeps recurring. I have bought a scanner which I can erase the codes because it is very dangerous to be driving 65mph with semitrucks on your tail when you suddenly for no reason lose power and can't get over to the side of the road. There have been many close episodes where we were almost in an accident. After the throttle body was replaced in dec 08, the reduced engine power didn't come back until april 2009. Dealer then rewired the harness and it stopped until the fall of 2009. Since fall 2009, the service engine light and reduced power mode come on sporadically. In february 2010, the problem reappeared, but now the truck stalls when the engine light comes on and reduced engine power is enabled. This is very dangerous, as during the stall, all power steering and braking is lost. I have been driving down the road, turning, crossing traffic, and the light comes on and the truck stalls. This is very dangerous and scary. The truck has been in the gm dealership service dept for the last 3 weeks. Everytime they say it has to be the throttle body, they replace it, I bring it home and a couple days later we are back to reduced engine power with service engine lights. Trouble codes are p2135, p0120, p1515, and p0220. I have spent nearly $2000 on service that has not resolved this problem and they don't know how to fix it. I have read online many others have the same problem. This truck is dangerous to drive now that it stalls every time it goes into reduced engine power mode (which happens multiple times on every time I drive it).

Gmc yukon xl 2500, 8.1l engine... Purchased truck (2nd owner) 8/2005 from gmc dealer. Noticed first occasion of stalling app. 10/05 or 11/05. Dealer said "couldn't reproduce complaint" and released the vehicle. Truck drove ok for awhile and began stalling again, this time gm dealer said "fuel pump" ($900+). Truck continued to stall on and off for years, each time no one could find problem.. Recently, summer of 09, it has become worse (more frequent and longer time to re-start) and after two independent diagnostic tests by two separate certified mechanics, it was determined to be the crank positioning sensor. I had already heard about this problem but since my VIN wasn't included in the recall (even though its the same year, model and engine) I am being told that the dealership will not cover!!! I don't know what else to do.. I cant drive this vehicle any longer because it stalls much more often and without any warning meaning loss of power steering, etc and risk of crash. I have called gm as recent as today (12/09) and they are still singing the same tune.."your vehicle VIN# isn't included in the recall". Next stop media outlets!!

Tl*the contact owns a 2001 gmc yukon xl 2500. While driving 35 MPH, the vehicle suddenly stalled and lost power steering. The contact attempted to restart the vehicle, but it took a few minutes. He drove the vehicle to the dealer and they replaced the crankshaft position sensor and there had been no further occurrences. After the repair, he discovered the recall for the same defect for the yukon, but not for the yukon xl, even though it had the same motor. He called the manufacturer and they stated that the VIN was not included in the recall, although the contact feels that it should be included. The recall number was unknown. The failure mileage was 82,000.

Dt*: the contact stated while driving 70 MPH on normal road conditions, the vehicle stalled. The vehicle would not restart, however the electrical system worked properly. The vehicle was towed to a dealer who determined the fuse of the fuel pump had gone out. The fuse was replaced. A few weeks later while driving 70 MPH, the vehicle stalled again. This time the vehicle was towed to a different dealer who determined the fuel pump wiring shorted and the vehicle needed a new fuel pump. There was a recall #01v159000 regarding the fuel pump. The vehicle was not included in the recall due to the VIN. When the manufacturer was contacted, a complaint was taken which resulted in a partial reimbursement for the repairs.
