2016 GMC Yukon Denali XL: problems, recalls and reliability

“I took my car into a gmc dealer due to a funny noise. I had to pay $800 to replace my brake vacuum. The vehicle was not braking properly prior to this fix.”Owner report · Service Brakes · Mar 2019

“My vehicle has only 47,000 miles and my passenger side brake light is out. There is also water and moisture that builds up in both taillights. I was told it would be $800 each to replace and was no longer under warranty. I am the original owner and purchased the vehicle new. The vehicle has never been in any accidents. This is a serious issue and needs to be covered by the manufacturer. The led lights should not go out this quickly.”Owner report · Exterior Lighting · Feb 2019

“I was on the ramp going approx. 45-50 mph accelerating to be able to turn onto the 70 mph highway when my sunroof exploded. It was like a gun went off in my vehicle. It scared me to death as glass was falling on me. I shut the inside protector and looked around and there were no people, trucks, cars or overpass around. There is glass all over the inside of my vehicle. The pieces continued to fall the rest of my trip. I contacted the dealership immediately and the guy said he never heard of it. Gmc headquarters was no help either. I have read this is a manufacturer defect.”Owner report · Unknown Or Other · Feb 2019

“Both tail lights have ceased to function within 6 months of each other. Gmc states that the original parts were defective, but will not cover repair. Each light costs ~$700 plus labor. This should be a recall issue.”Owner report · Exterior Lighting · Feb 2019

“Drivers side brake lights went out, car is only two years old. Three weeks later passenger side brake lights went out. Driving on a highway for three hours as people honked and rolled their windows down to let us know we didn't have brake lights. Took to get fixed and the lightbulbs, which are led and should have lasted longer than two years, are not replaceable, the entire tail light assembly needs to be purchased at $700 a piece. When people are unable to afford $1400 before labor they will drive without brake lights. This is a serious hazard and a ridiculous manufacturing flaw to have light bulbs that are not replaceable. Gmc should be held accountable.”Owner report · Exterior Lighting · Jul 2018

“Takata recall - the brake lights work on and off. Sometimes they come on and we've been stopped multiple time to say they are not working. I've almost been rear ended as a result! Extremely dangerous driving condition. It fhas occurred when I am at a stop light or driving and slowing down on a city street. I have seen many gmc yukon xls on the road with no tail light and my sister owns a 2016 yukon xl and is having the exact same issue.”Owner report · Exterior Lighting · Jul 2018

“At 76,000 miles the transmission began to shudder violently and hestitate. Dealership gmc wants me to spend 400 on a fluid upgrade and hope it fixes it if not, I will have to buy a new updated torque converter because they shrewdly took the drivetrain warranty down to 60000 miles months before I bought new”Owner report · Power Train · Jul 2018
