Vehicle randomly goes into reduce engine power mode and stalls while driving. This has happened multiple times while driving on a highway and going up a hill where it nearly caused a three catastrophic accidents. Basic research shows that gm has known about this issue since the vehicles were a few years old and it affects many years of gm vehicles. There is a problem with bad grounding connectors related to the throttle body sensor and and wiring harness.

The vehicle was taken to a local dealer who was unable to duplicate and diagnose the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 200,000.

This basic incident has occurred approximately ten times. The 4wd control module malfunctions at random. The vehicle message center will display "service 4wd," and a clicking sound can be heard as the lights on the transfer case control panel switch on and off, switching the vehicle in and out of gear. Several times this has happened in such a way that the truck shifted into 4lo at moderate speed. Once, the vehicle stalled in an intersection with the abrupt shift. I am convinced that this is a systematic issue with gm 4wd trucks, but it is in no way being addressed. It is an extreme safety hazard when a 5400 lb. Vehicle suddenly shifts into low range or neutral without advance warning. A simple internet search shows that this has happened to many other gm vehicle owners. The only remedy seems to be removing the relay to cut power to the module, thus rendering this "mighty" 4x4 a 2wd sled. This is a safety hazard of the highest order! I cannot say enough negative things about the electrical system of this vehicle in particular and the build quality in general. It destroys tires, it is a pleasant surprise when something works as it should, and I had to replace the "heavy duty" transmission at 120k when the power bands catastrophically failed. For shame, general motors! I will never again purchase another of your shoddy vehicles.

During acceleration and occasionally during braking, the wheel sensor(s) cause the traction control to become active, or cause the anti-lock brakes to engage. In all cases, activation is in error based on ambient conditions. I am able to override the traction active problems by disabling the traction assist, but the anti-lock brakes are not controlled by the same switch. I have searched the internet and found numerous examples of the same failure with this type of vehicle, but no recall exists yet for this particular year and model. To date, the failure has not caused a crash, but now that winter is here I have to make repairs because disengaging the traction assist is not practical in snowy conditions. My mechanic advised me that it requires changing the full front wheel bearing assembly because of corrosion buildup on the tone ring. He also told me that he did change a sensor on a similar vehicle but the sensor did not solve the problem. The wheel bearing will cost several hundred dollars to replace. With the apparently common nature of this problem, and a listed recall in canada for the same problem, I believe gm is ignoring a very serious safety problem. When you pull into traffic and the vehicle essentially stalls, you may get rear-ended, which almost happened to me a few weeks ago. However, my greater concern is not being able to stop. Another website said that tires could be the problem. All of my tires are the same size and wear, and air pressure matches. The problem is with the vehicle, not related to tire differences.

2011 2-wd yukon xl 1500 engine stall. Took delivery 7/1/2011. On 7/5/2011, while driving at city speeds, engine stalled (shut off), was able to restart. This happened twice consecutively. Did not experience again until 7/14/2011. This time was driving in center lane, 5 lane freeway, during rush hour at posted 65 MPH speed. Again, engine stalled (shut down). During 3 cycles of stall/shut down/restart, was able to make my way to right lane, drive/coast to exit ramp, exit freeway and enter a retail parking lot without an accident. During process, heard a pop/click to my left in the dashboard. Turned off air conditioner, restarted truck and made my way home. During this drive home, the alternator/voltage gauge needle bounced to extreme right for a short period of time, then settled back closer to center. Prior to incident, I had noticed same needle occasionally/oddly slight to the left. Truck was towed to selling dealership that evening. The following day, the service department ran full diagnostics and reported "nothing wrong with the vehicle/operating normally". There are no "codes" or any "history codes" showing anything abnormal occurred with the vehicle. 7/18/2011 opened case file with gm, but little assistance has been offered by them other than "we called the dealership". Truck has been housed at the dealership now for 11 days. We are at a stalemate. Our position is the car is not safe to drive. Dealership/gm's position is they can find nothing wrong with the vehicle. They have suggested we pick up the vehicle and drive it until the problem occurs again then again have it towed to the dealership. Our response is: if we agree to do that, and are lucky enough to again "survive" the occurrence without being involved in an accident, why do they/we believe they will be able to diagnose and repair the problem? We are waiting for someone/anyone to involve the factory for further technical assistance to resolve this problem.

I purchased a 2002 gmc yukon xl 2 days ago, sold "as is" with no warranty. At the bottom of the speedometer are the lights that indicate the position of the shifter (park, reverse, neutral, overdrive, and gears 3,2 and 1) and also the odometer reading. These indicator lights worked fine during the test drive but became intermittent on the drive home from the dealership and while driving the vehicle since then. You lose all indication of what gear you are in and of the odometer reading. This problem could lead to a driver shifting gears improperly and unsafely, such as shifting into a forward gear in a parking lot when the reverse gear is intended or shifting into reverse while driving and seeking overdrive after being in a lower gear. I have now been told by a few dealers that instrument cluster failures are somewhat common in yukon xls and are costing an average of about $700 to replace the entire instrument cluster when only a single gauge is having an intermittent problem. Since the problem seems to be common and can effect safety, as in the examples I gave above, please investigate this problem and see if a recall/manufacturer fix is warranted. I just investigated driver complaints around the internet and found several complaints about yukon xl speedometer failure/intermittent, for instance. If a driver doesn't know what speed he is traveling at he is a less safe driver and a potential hazard to others. Excessively slow drivers and excessively fast drivers can both cause serious problems in traffic, and in rural areas there may be fewer, if any, drivers alongside to help gauge the normal speed that is appropriate. Also a vehicle could unexpectedly fail or stall in traffic, causing an accident, if a driver is unaware of an extremely low battery or low fuel, etc. Instrument clusters are very important for safety in many ways. Please investigate problems with intermittent and failures in the instrument clusters used in 2002 gmc yukon xls. (mine is a 1500).

I have a 2002 gmc yukon xl. This vehicle that I recently purchased has stalled on two occasions while driving. Both times I was in traffic and had difficulty safely getting off the roadway, as I had no power. I have done a fair amount of research and found that I am 1 of many with this complaint.

Tl*the contact owns a 2007 gmc yukon xl 1500. The vehicle has had multiple failures. While driving 70 MPH, the vehicle suddenly stalled and shortly afterwards, the power steering and brakes failed. After the first failure, the vehicle was towed to the dealer and they stated that the software in the computer system needed to be updated. After the vehicle was repaired, the failure recurred six months later at the same speed. The vehicle was not towed on this occasion because the contact allowed the vehicle to sit for a couple of minutes. The engine restarted and the contact was able to drive the vehicle to the dealer. They attempted to update the software again; however, the failure recurred less than one week later. The dealer updated the software for the third time, but the failure continues to recur. The dealer has been unable to permanently repair the failure. The failure mileage was 10,000 and current mileage was 28,000.
