Front differential fails on awd versions of Yukon/denali models. Unusual front driveline noise is experienced especially during light acceleration or load. Noise is a whine type of load. This one failed @ 54,000 causing dealer to rebuild front differential with new bearings and seals. Old bearings were badly scored and one of them broken to many pieces. I asked for parts and was given what could be pulled out. Internet search indicates many owners with awd systems which were also available on Yukon as well as denali models have had similar failures. Cost to repair as warranty expired at 40,000 miles was approx. $1000.

2006 GMC Yukon xl - purchased in Jan. 2006, the vehicle was taken in for service 1 month after taking delivery for foul smell emitting from vehicle while moving. It was diagnosed as the rear differential producing the odor, they changed the fluid to the old synthetic type, and claimed it was the smell of the grape seed extract used in the organic new type fluid. This did not solve the problem, the next time the service center tried an oil which had a higher heat rating, this did not fix the smell problem. On the 4th visit to the service center and after opening a customer claims case with gm, they rebuilt the rear differential. This seemed to solve the problem for about the first 6-8 months, the smell returned and got significantly worse until I opened another case withgm customer claims. While working with them the differential went out on the vehicle leaving me to rent a car on my own until gm decided what they were going to do about it. I am currently in a bbb case with gm.

: the contact stated while attempting to turn at 15 mph, the rear driveline differential broke followed by a banging noise as though it was dragging. The vehicle was seen by a dealer for inspection. While the mechanic test drove the vehicle, the driveline differential unit completely separated. The vehicle is currently at the dealership awaiting repairs. Updated 05/04/06.
Four wheel drive makes grinding noise during turns. Manufacturer advised me that this is normal.
Had taken vehicle to dealer for brake service on front disc brakes due to wear on disc. Work after 15000 miles had to be performed again due to disk wearing out. Consumer believed that brakes were not heavy enough for vehicle. Disc warped causing vibrations and brake failure. The disc was turned a t 15k miles and was replaced at 28k. Transmission does not hold on hills. Front end was leaking due to front pinion seal failure . .

This vehicle has been a problem since we bought it. Right after we bought it we heard a roar in the rear end. The rear end was replace under the 3yr/36000mile warranty. Soon after that the alternator was replaced under warranty. Just recently we took a trip and towed our 18ft. Ski boat with us. When we returned my wife noticed a problem the next day. We had no reverse and that proved to be the transmission. We contaced the closest dealrer to mike morgan shreveport, la. They told us that they were so backed up with tranmission problems that it would be at least a week before they could pick up the truck to even look at it. Then they would tell me what they thought. Well, I paid $25,000 for a vehicle to sit with a bad transmission and they think I will let it sit while my wife and children walk!!! I don't think so! during the last of July, my brother and law and I replace the starter on this same truck to the tune of $250. 00 yesterday I found a water pump leak and was told that would cost me around $200. 00 to repair. Oh yes, the transmission cost me $1,400. 00 to repair. As you can see, I am having a ton of problems with this vehicle. Gm has thumbed their nose at me and more or less said "tough luck"! well, I don't think that is fair. The transmission is what really upset me. I paid extra to have towing package on this truck and we pulled a boat 1 time and this happens. I can't beleive that this truck can't get at least 100,000 miles on the original transmission. I also have a boss that owns a 1999 suburban that had the tranmission fail on him this last Friday. His truck has only 54,000 miles. Well, as you can see, I think gm has a problem!!! please let me know what I can do!.
