2016 GMC Yukon XL engine complaints
Page 2 of 2: complaints 11 to 29 of 29, newest first, as owners wrote them.
In June 2024 I took my vehicle to the dealership for a ticking/clacking noise. The dealership determined lifter failure and that the engine needed to be replaced because the lifters/cam were not readily available from the manufacturer due to a known issue with L87 GM motors. Long block was replaced 7/17/24. I believe this should be part of the recall issued against L87 motors and should be extended beyond the 2021-2024 years initially noted.
6.2L collapsed lifter on cylnder 5. This os my second engine with the exact same problem as the first engine reason for replacement
After leaving a car wash on 12/19/22, the engine began sputtering and did not seem to be able to get any gas. After pressing gas pedal, the vehicle slowly moved forward, but was shifting hard. Pulled over in gas station parking lot and turned vehicle off. Checked Engine. Vehicle would not restart. Vehicle was towed to dealership. They uncovered a broken valve spring, which also caused the catalytic converters to fail. Total bill was over $7500
Having to replace an engine at one hundred and three thousand miles…not something I would expect

Like many other complaints..when your driving and accelerating it jerks and try’s to change gears ect. Most recent issue is the temperature sensor went out and my fan was running on full speed. Well I got it fixed and within 2 months it has gone out again! Lastly, the paint on the hood and roof. When I bought the dealership fixed the hood and yet again it’s failing again..

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.

Bought SUV 6/25/2016 the same weekend the engine turns off after a left or right turn :it has happened 3 times so far. 4 week old 2016 yukon denali xl, has stalled 3 times in last 4 weeks, engine cuts off after a left or a right turn only after a short drive out of home. The SUV has to be restarted! Could have easily had an accident or worse. I took it to the westpoint gmc dealer, 3 times. 1st two times, all of service deptartment could not diagnose the problem. Today, after a stall, I called onstar, who ran a diagnostics test,but onstar found nothing of value , I left it at dealership and contacted district mgr. Matt tillson . I was told that they would escalate the issue. I did tell dealer that gmc and dealership would be at fault if vehicle is involved in an accident and stalls nor stops while I am driving. I did not want the vehicle back without the problem having been fixed. Its day 6 today. I need to make it absolutely clear, I will not take the vehicle back untill the problem has been diagnosed, and fixed. I do not want me or my family or gm service employee injured, or worse, or to be involved with a possible accident in my gmc yukon denali xl. A field service engineer should have been on this case already ! Will it take an accident, or injury before someone gets assigned?
In my yukon while idlel the car start shaking so bad, it has a vibration you can see the needle going up and down, took it several time to the dealer and they said they know is a problem with the car but general motor company has not issue any repair for that at this moment, I contact general motor company they said the car is operating normal base on the report provided by the dealers, for me is not normal having a brand new car shaking and vibrating like if will turn of, looks like if misfired on the engine,
