general problems of the 2011 GMC Yukon

I have replaced the battery and alternator. My door locks keep locking and unlocking on the own while driving, all my electrical in my car dim and keep resetting, my gauges are going all over the place. My car will turn itself off. While stopped at a red light, it seems to want to go on its own. While not running, I get in to leave, and my key at times don’t want to turn over. Then at times I try to start it and it will tell me theft control and won’t crank. When I’m out of my vehicle at home, my car will lock itself when the setting is turned off. The problem has been going on for a year but only getting worse now.

Vehicle shut off while driving on the highway. No warning signals and happened multiple times over the course of the day. Speed was 70 mph.

The car seat warmer in the back of the car caught on fire while our seven year old was asleep in the car. He was in his booster seat. The seat warmer was not on. (this was in August 2018. ) we smelled a burning smell and there was a smoldering flame under his legs. The car was stationary, not in motion. It was idling in a parking lot.

Power liftgate won't open, unlock or lock. Actuator has been changed along with both struts. Could it be the power lift gate module?.

The dashboard has large cracks over the instrument cluster and in the area of the passenger air bag. The dash flops up and down when driving. Concern is crack could prevent passenger air bag from deploring during a accident or ripping the air bag at deployment. Also liquid could accidentally go thru crack over instrument cluster causing electrical short or fire. The crack continues to get larger and larger.

The seat heater in the rear right seat overheated and caught on fire while my 10 yr. Old child was seated in it. We were in motion at the time on the interstate. I believe the heat mechanism failed and overheated and would not shut off causing the cushion to catch on fire. My insurance will not cover it (I did get a estimate to fix cover and cushion) and they suggested gm should investigate and fix the seat due to a major defect. Gm was no help and wanted to charge me $800 to fix or turn it into insurance. They acted like they have never seen this before and I caused it somehow.

I am having issues with the antenna in my truck. The radio is constantly going in and out. My onstar has stopped working completely. My bluetooth drops calls within a few min of taking the call if I can even get it to answer the call. Cosmetically the issues I am having is the dash has a huge crack right behind the steering wheel it goes all the way across to the passenger airbag. If I was to have a front end crash shards of plastic would go flying this is a safety hazard. I just purchased this vehicle about 2 weeks ago 3/11/17 and have had these issues since purchased. Any recommendations are welcomed. Thank you.

I have a 2011 GMC Yukon, I recently learned from GMC that they have a known issue with these vehicles by where they shut off randomly when an rfid key tag in or around the vehicle interrupts the vehicles electronics. Our vehicle has turned itself off on multiple occasions which has created a huge safety concern for my family driving our Yukon. GMC discovered/reported this issue internally in June of 2015, and our dealership reluctantly provided me with a copy of the GMC bulletin (see attached). Gm says they cannot fix the issue and will not repurchase our vehicle. Gm says it is not a safety concern but will not put that in writing, their employee handbook does not permit them to put matters like this in writing as it can be used against them in the event of a catastrophic failure. I¿ve contacted every level within gm, up to the executive office, in an attempt to resolve my issue and they have run me in circles and denied the know problem is a risk to the safety of my family. This messaging was reported down from the gm executive liaison, lawanda dean, from a man named rod (will not disclose his last name) who is the regional manager of GMC, over California. I'd like to know why this is not a recallable issue, why gm is allowed to not fix such an issue and if the NHTSA will assist me with this matter. Had GMC told me that my Yukon would randomly shut off we never would have purchased it.

The rear defrost wires kept falling off of the window. I had them soldered back on several times until I finally had to replace the entire glass, because there wasn't enough material to be able to re-solder it. Within a couple of weeks of replacing the glass, one of the wires fell off. I had it fixed. Then a few weeks later the other one fell off. In total over the next year I had both wires re-soldered at least twice each, until just last week when I had to replace the glass again! I was told that this is a bad design by gm and that they tend to fall off because they get too hot when in use. However, the wires even fell off in the spring and summer when the defrost wasn't in use.

Doors have locked on their own three (3) times.

Large cracks in dash causing constant rattling noise. This occurred in less than a year purchase and has worsened the heating and cooling function of the seats failed within months of buying the vehicle new. Radio and navigation screen does not work at all.
