2016 GMC YUKON XL

AIR BAGS:FRONTAL

General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

Risk: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.

UNKNOWN OR OTHER

I bought 2016 Yukon XL 9/2020. At 74k miles (2022), the transmission was replaced by warranty. Now (2025), at 126k miles, the transmission needs replaced again. This can’t be normal.

POWER TRAIN

The transmission is going out and it started with a shudder. The change for the transmission filter and oil was only a temporary fix. It also shifts hard or there is a delay in the shift.

ENGINE

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 serviced according to schedules and receives only typical local and commuter use is out of the norm. It is the first generation of GM's 6.2L engine and the sister engine to the one currently under major recall and no-sell orders. We believe that GM knows of these issues as we have spoken with other people who have had similar problems. The problems involve the valve train and the crank and pistons much like the recall on the later models. Please advise what we need to do to move our complaint through the system to see if we can get some relief on this matter. The dealer still has the vehicle so we don't have any paperwork yet on the latest incident. I will send the November 2021 information

Chest Clip, Buckle, Harness

Chest clip does not remain clipped. It releases without pressing the release buttons.

SERVICE BRAKES

I have repair the trailer brake system warning light prior. Now again this faulty wiring module is constantly dinging and flashing warning messages while driving. It's very distracting and irrelevant considering I not towing anything. It covers the speedometer and is a complete nuisance.

ENGINE AND ENGINE COOLING

The contact owns a 2016 GMC Yukon XL. The contact stated while driving approximately 70 MPH, the check engine warning light started to flash. The contact stated that the vehicle started to lose motive power. The contact depressed the accelerator pedal, and the vehicle shook violently. The contact pulled off the highway and the vehicle stalled. The contact restarted the vehicle, and the check engine warning light was flashing with DTC: P0300 displayed. The contact stated that the engine was making an abnormal knocking sound. The contact turned off the vehicle and the vehicle towed to the residence and then to a local dealer. The dealer diagnosed the vehicle and determined that a bearing in the cam shaft had failed and had sent metal shavings into the engine. The dealer determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included. The failure mileage was approximately 175,000.

POWER TRAIN

The transmission quit working and we were almost in an accident. This is a known issue on the interweb and I think GM needs to step in and help!

ENGINE

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.

ENGINE

6.2L collapsed lifter on cylnder 5. This os my second engine with the exact same problem as the first engine reason for replacement

POWER TRAIN

When accelerating from a stop, the engines revs up to really high RPM's before shifting hard into 2nd gear, and again while shifting hard into 3rd gear. This started in the last week. The engine/trans currently have ~133,000 miles. Accelerating slowly, not exceeding 1,500-1,700 RPM will reduce this occurence, but it takes significantly longer to get up to speed, which is a problem when entering 55 MPH traffic. We've had to pull off the road to avoid causing an accident while merging with traffic since the transmission seems like it won't shift, causing me to have to let off the accelerator to try and allow the transmission to shift so I can continue accelerating.

FUEL/PROPULSION SYSTEM

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
