2016 GMC Yukon XL Other or unknown Problems

“Brakes do not work at low speeds. Gmc told me that the parts had been bought back by GM and there was no way to fix it 8 months ago and now they state there is a special warranty added except my mileage is over the warranty! Brakes either are hard as a brick to push or/and don't work at all. I was told to rev the engine when going slow or backing up in order to make the brakes function properly. That was the advice for a mother of 4 children. Ac is also blowing hot air.”

“The front collision avoidance system does not work. I can set a 1-3 bar alert on the steering wheel, however in the 3 months I've owned the car and trying different maneuvers at different speeds, I don't get a an audible nor visual red light warning that I've experienced on a newer chevy impala I drive. The dash info center below the gauges will change from a green semi-circular 3 bar system to a yellow if I come within the 3 car lengths set of another vehicle while driving. …”

“My driver side LED taillight went out. You can not just change a bulb or the LED strip. It requires the whole assembly be replaced. My vehicle is 2 years old. It should not gone out after 2 years, let alone it being an LED which is supppse to last much much longer than that. I was told while driving, it would go on them off. It was dusk and I was driving on a surface street with lots of traffic. That is not safe. I have multiple friends and family members who have also had this problem. The internet threads have many more complaints as well.”

“I leased a 2016 yukon denali xl on 9/15/15. It has two major problems. 1. Buffeting/pressure noise - a noise as if a window is cracked, except it's not cracked. This occurs at speeds from 24mph and up and causes ears to pop and is noticeable to virtually every passenger I have had. 2. Whole-truck vibration - occurs between 70-80mph in entire vehicle. Wheel replacements, tire replacements, road-force balancing, driveshaft replacement, driveshaft balancing , etc....nothing has fixed it. I have driven 13 2016 yukon, Yukon Xl, tahoe and suburbans. Every single one has the buffeting issues. …”

“Vibration at speeds over 72 MPH becomes worse while going up grade while accelerating ..has been in shop many times new tires, balanced multiple times ,along with suspension parts and drive train parts. Still not fixed SUV has 22 inch rims.”
