GMC Yukon owners have reported 19 problems related to transfer case (under the power train category).
Transfer case failure causing multiple other component / system-wide failures including advance safety features, engine power reduction, 4 wheel drive system failure, bluetooth connectivity failure, radio failure, traction control failure and more.
Transfer case engaged into 4wd while dring with touching any of the controls. Now it won't switch out. Service 4wd light appears.
This is the second time the following occurred. (oct 27,2014 and now on Nov. 5,2014). When I went to drive the car, suddenly the car did not turn properly. If I made a sharp turn, it sounded like the front wheels were rubbing. The car was in 2 wheel auto. I immediately called the salesman and explained the situation. I drove the car on the highway (65mph) to dealership. Day later, loose wire in transfer case. Everything fine. Same thing occurs on Nov. 5th and the salesman tells me to take a video, which I do, and bring the car in. Today I am told it was the computer program that was the problem. The salesman confirms that the auto was in 4 wheel drive when I brought the car in but the receiving and delivery service technician now says it wasn't. He said the 4wd light was not on and he only felt a little bit of a rough ride when I dropped it off. He also told me that the state of virginia does not have a lemon law, which he back tracked after I called him on it. Other problems with car. Nav/radio/backup camera went blank on Nov. 4th. There is a whistle noise on the top of the drivers side door. The ride is substandard to my old 2007 GMC Yukon xl denali, which I bought new and had 197k miles. You feel every pebble or road imperfection. You get the typical response as if this was a $5,000 used car and not an $78,000. 00 premium SUV.
I have a brand new 2015 Yukon denali (short wheel base) with less than a thousand miles and a "service 4wd" message that has appeared twice rendering the car extremely unsafe and un-drivable for a long distance and having to have it towed to the dealer twice. A software update was done on the car the first time, only resolved the issue for a few weeks, the issue re-occurred after 3 weeks. When turning the vehicle on the dash gives the message "service 4wd". The car has a transmission button to change from 2wd, auto, 4 high and 4 low. I do not touch this button, I just leave the car in auto and drive. I do not tow anything, this is just a family car used for commuting. When the "service 4wd' message appears, the car is barely drivable. When it is put in reverse, the car just brakes after a few feet, as if the parking brake were on, but it obvious is not engaged. When turning left or right, the car brakes mid-turn and will only complete the turn if 3/4 to full accelerator is applied to continue through the turn. The car slightly bucks through the turn and the engine sounds different and has little power going around corners and going up hills. The car cannot safely be driven in a straight line faster than 40-50 mph. I telephoned onstar and diagnostics were run during both occurrences with the same error message from onstar diagnostics: "the braking system has an issue- transfer case module not working as expected". When will gm issue a recall on this safety issue, I do not feel safe letting my wife and child in the car if it brakes by itself, loses power and cannot complete turns. I purchased this car to have a safe/large vehicle for my family: service 4wd appears on screen it renders the car un-drivable and the transmission button becomes inoperable and selecting other transmission modes becomes not possible.
I was driving down interstate 55 coming from sikeston mo headed to st louis with my family. As I was driving I heard a loud bang and the truck had begun to vibrate after pulling of I noticed that there was fluid leaking out. I had to have the truck towed back the mechanic assumed that the transfer case was gone out but upon removing the transfer case it was the transmission adapter had shatter I had many dealers look at the piece and they said they have never seen nothing like it. The metal gave away for no apparent reason nothing else was damaged except that transmission adapter. It was frighting for my family and myself I would like some answers on why this happened thank you so much.

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.
Service 4 wheel drive message came up on instrument panel(dic). Shifting into 4 wheel drive amber light kept flashing denoting transfer shift did not occur,however shift could be felt. Manual clearly states do not shift into gear or damage can occur to tranny. Dealer fixed; got home & same problem . Worked intermittently. At dealers now for 2nd time -gave me loaner car . Found 2 service bulletins same problem on NHTSA web site.

2003 GMC denali front transfer case failure. While driving on the highway I noticed a loud noise for a few seconds, then it stopped, so I drove on home and the next morning I dropped it off at my personal repair shop. To his findings it was the front transfer case. So he called the local dealership and talked to someone he knew that worked at the dealership in the parts department and they told him that the dealership had repaired several denali's with the same or similar problem just this year.
The contact stated about three -four weeks ago the abs kicked in at low speeds, and he has no stopping power. The dealer told the contact the bearing hubs needed to be replaced. About two weeks ago he noticed a grinding noise coming from the transmission area. The dealer told him the transfer case needed to be removed and likely replaced.

Bearing and ticking noise coming from transfer case when using 2h at 65 mph & greater. Noise goes away in auto 4 wheel.
(1) none (2) pulled out on hwy at normal speed, loud wining, and loud pop. Transmission failed, left with only 2nd and 3rd gear. (3) called transmission shop and they described in detail the flaw that caused failure. They informed me that this was quite common in this model. I feel that this should be reported as a recall, to correct this defect.

While driving my 2002 Yukon xl, there is yellow light appeared on the I/p cluster message center. "service 4wd" and when gently apply/pressing on the brake pedal, the is some kind of loud mechanism noise in the front wheel driver side, and prevent the brake pedal from coming down. Three times that I almost rear end other vehicles. Took the vehicle to the dealership to get it fixed, the cost was $2212. 93 for fixing brake system failure including anti brake system and 4wheel drive. Dealer recommended to a report to NHTSA.
On 11/23/04 left for vacation noticed that fluid was leaking about two hours into our trip. Stopped at dealership in barstow, where we were told transfer case was heating up and expanding and that it had tiny cracks that the fluid was leaking out of. Needed a new transfer case ordered on 11/24 and authorized overnight shipping. Called from 11/29 to 12/3 when I was finaly told that part was on nationwide backorder and would not be shipped. My car was not ready until 12/15. I have concerns that this is a wide spread problem since the part was on backorder and that GMC will not reimburse parts and labor or rental car fees. I was also very disappointed in the customer service department. Contacted them and was told what info. To send. Sent it did not hear from for approximately three weeks then was told that they did not receive all info. Left at least 15 messages and never received phone call back called and asked to speak to supervisor and first was told no then finally found a representative that gave me supervisor. I resent paperwork that was supossedly missing and was told about a week and a half later that they would give me credit toward a new purchase or oil changes for the equivelant of 1 year.
1) 4wd faulty encoder motor failure--switch to engage 4wd failed; occurred at 75,841 miles on 12/31/03
2) could not put vehicle into 4wd when on winding, narrow, snowy road; fortunately no accident. 3) 4wd faulty encoder motor replaced on 1/3/04, but we had to pay for it & 4wd rental car; $938. 46 & 180. 15, respectively
note: I am now reporting this because an accident could have been fatal and I have just heard that other 4wd same SUV's, Yukons and chevy tahoes, have had the same problem, and the manufacturer refuses to recall this component.

The contact stated when making turns there was a screeching noise coming from the rear of the vehicle. In snowy conditions when the four wheel drive was engaged there was difficulty driving followed by another screeching noise when shifting from automatic to four wheel drive. The vehicle has been to the dealer for inspection. The dealer overhauled the four wheel drive, but noted all four tires were off balance and varied in size. This could possibly be the culprit of the screeching noise when turning. The tires have not been replaced.
We purchased a 2003 GMC Yukon. Before it had reached 3000 miles the neutral light came on on the 4x4 unit. From there it would shift itself into 4 low. We have had it into the dealer a total of 6 times now and they have replaced one of the components 3 times, two of the other components once. After the secon d replacement it started showing neutral again on the 4x4 unit. It seems as though the problems do not arise until after 1000 miles. The dealership service department told me that they have had a lot of problems with these units. We are trying to do a buy back but gm is dragging things out and giving us a hard time.
While driving the vehicle about (35) mph the retaining ring broke and fell into the oil pump inside the transfer case and caused steering problems and loss of power. The vehicle is being repaired at dealership.
