Turned on car, service 4 wheel drive message on display. Car will not move. Stranded with small children for 1 hour waiting for a tow. Only 616 miles on the car - had for a week. Why on earth was the recall not performed at the dealership prior to selling a $70,000 vehicle?

After owning the 2015 Yukon denali for 6 months, I have to say this vehicle has its flaws. The 4WD system is in for service already after 9000 miles. Not the kind of quality I would have expected on an $80,000 SUV. At the moment, the vehicle is only a 2 wd system and seems very difficult to drive and turn. Also, the intellilink software is very "buggy" and needs many updates. On several occasions, the entire touchscreen will go blank while driving down the road. This is cause for concern and is a major driving distraction.

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 premium SUV.

I was backing out of parking space in the mall parking lot when the service light came on. It stated service 4WD. The truck was very hard to steer and wouldn't change into 2 wheel drive I was 40 miles from home and burned over a 1\4 tank of gas. With less than 6000 miles I must say this isn't how I expect a $60,000 truck to perform.

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 just completed a claim for my 2015 Yukon denali, NHTSA id #: 10643049 and read that almost the same exact issues are going on with the 2015 Chevy Tahoe models, see: NHTSA id number: 10638437, 10633519 and 10631583. When will GM see there is a pattern and issue a recall for this transmission issue? in all cases these render the calls un-drivable and having to have them towed.
