2016 GMC YUKON XL Complaints

Without warning my 2016 Yukon Denali jerked so forcefully into drive it felt like we were hit from behind. It went into gear and sped into intersection and stalled. We were almost hit. This is a huge problem with2016 GMC's and they are aware of it. It is the 8 speed transmissions that are causing this. They refuse to help get it fixed. I think they should be forced to! I will be out thousands if I can even find a shop that can get that transmission., They are back ordered because so many failures.

At 90500 miles my Yukon xl started shuddering and the transmission started failing and I have never used it to pull anything so this was very dissatisfying for a 75k vehicle

The taillights, which included both the brake lights and running lights, quit working or only worked intermittently. Safety was put at risk because anytime we drove the vehicle in the dark (which is often!) the rear of the vehicle could not be seen, and the brake lights would not be activated when braking would occur, either day or night. This made us more likely to be in an accident, in my opinion, though thankfully we were not. Our regular mechanic did confirm that the lights were only working only intermittently, thought he did not have a solution but for replacing them, which would cost $800 a piece. There was no warning for this problem, the issue first appeared a year ago and we've been dealing with it since. I was finally able to purchase remanufactured taillights.

While driving down the freeway, I received a warning that the charging system was not working and had a red battery light come on on the dash. I exited the freeway trying to get to a safe place, the dash and infotainment system begun to flash on and off. We heard a loud pop, smelt something burning, saw smoke coming into the cabin and then flames from under the hood near where the battery is located.

r rear taillight and brake light does not work and no indicator light to warn me. Do not know how long its been out. Afraid to drive. Had it checked and found special policy n182180270 . I contacted dealer and they said it would be $69.00 to just verify issue. contacted manufacture and was told it was out of coverage by less than 100 days. The vehicle has less than 40,000 miles and stays in garage. Case # 9-8269822 they said it had to be inspected by dealer that is a 40 mile round trip though traffic with no brake light , not safe especially when the instructions on the policy states just to turn light on and verify if it works ,if not replace unit.

The fuel injectors have gone out on our vehicle. While driving the vehicle, the check engine began blinking and our vehicle went into limp mode- could feel the engine misfiring and the vehicle was shaking. We had a family of five and two dogs in the vehicle and were lucky to be in cell service. A message popped up on our dash stating “engine power reduced.” The local dealership confirmed it is a fuel injector issue. GMC has a current recall In place, however it only includes certain states.

2016 Yukon XL ~ 90,000 miles. This is the second time I get a low speed braking failure when trying to park, followed immediately by a "Brake Assist Malfunction" warning on the dashboard. Both failures have occurred after a long distance travel. The last one being from Detroit to Chicago on 7/30/22. The failure consisted on the SUV not stopping after I had applied the brake pedal at full when backing up for a parallel parking on a street in Chicago. Same happened after I drove forward almost hitting the car in front of me. The SUV continued moving for about a foot on both situations. Before this incident, similar situation happened on a trip from Detroit to Cleveland on March 2022. The SUV continued to move fwd after I had applied the brakes. In this occasion, I was on a ramp down getting into a parking garage. The SUV did not stop for an approximately a foot as well, and again almost hitting the car in front of me.
