2016 GMC YUKON XL Engine Problems

My vehicle has been in 16 times since I bought it the most recent incident is for the engine which started about six months ago. It’s been in since then for other issues concurrently with this one it hesitates like it’s getting stuck in sand before it wants to go first the mechanic told me he didn’t sense it but the thermostat was stuck open so they fix that. Second time it went in they thought it was some sort of a filter and some other components I’m not sure. Again it was not fixed then my son and I were out in Minnesota freezing cold night in November and go and drive and then when again it was the drive train this time that got fixed a month ago about a week ago it starts making a noise like there’s too much snow in the tires. I get my...

Driving after dark on a main street in St George Utah, the engine suddenly surged and then revved down. It felt like someone jamming it into 4WD. Traffic was tailgating me, and I was nearly hit. I could not pull completely out of the right lane. I put on hazard lights. Check engine light came on, and TCS light came on. I decided to get out of traffic & crawled forward about 30 yards into a Sinclair station lot, then backed it into a spot where a tow truck could get it. It was clearly not drivable. Called AAA and a driver was able to get to me within 1/2 an hour. Checked the AAA website for mechanics since I was merely travelling through St. George and had no knowledge of the area. Hawker's Automotive was listed first, with many excellent reviews. Tow truck arrived and driver loaded it on...

There is a hesitation when trying to accelerate. The car will then slam forward and there is a rattling noise that the car also makes. This has almost caused accidents. I was driving in town which is where I do most of my driving.

The engine is the component that failed and is available for inspection. The issue has been confirmed by an independent service center, and the repair quote is attached. There were no prior warning signs before the failure; the vehicle suddenly began making a knocking noise and experienced a loss of power.

While driving vehicle the vehicle appears to shut off as if someone is turning off the ignition. The steering control becomes stiff, power is lost and electronics flash and turn off and on. This has happened on multiple occasions and is intermittent during acceleration. The accessible grounds have been checked, battery checked and replaced, and alternator checked and verified to be charging appropriately. Several codes are present and have been cleared to return indicating low voltage issues with multiple systems.

We own a 2016 GMC Yukon XLT Denali with the GM 6.2 engine. On Saturday, July 26, 2025 our vehicle suddenly lost power and became undrivable in traffic. We had it towed to our GM dealership who still has the vehicle (Reiselman GMC- Springfield, TN) They called today and said the engine could not be repaired. They stated it had no compression in Cylinder 8. The said our only option was a new engine. THIS IS THE SECOND CATASTROPHIC FAILURE we have had. In November 2021 we experienced another CATASTROPHIC FAILURE when the vehicle suddenly lost power. The engine required a valve and valve spring and seal on cylinder #1. This is 2 major failures we have had which could have been dangerous had we not been able to get out of traffic. The vehicle currently has 116k miles. These types of major failures in a vehicle that has been...

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

Merging onto highway and my car would not get up any speed . Was almost crushed by a tractor trailer. If I hadn’t had a long merge lane I could have been killed . Apparently my transmission failed. This is certainly a safety issue . Your car should not just quit! .called dealer and they said the problem is known but gmc is not doing anything about it! Please help 75,000 $ car should last !

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.
