Component: SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:WHEEL SPEED SENSOR/TONE RING
General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Consequence: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

2019 GMC Youkon with 94,659 miles. I am the second owner of this vehicle. I purchased it used in February 2025. Check engine light came on in route to work on March 5, 2026. Immediately took vehicle to Auto Zone to scan for codes. Multiple codes were returned. I drove it directly to a repair shop for further diagnostics. Return Results were massive lifter failure and cam shaft damage. Why would the check engine light not come on sooner to prevent TOTAL FAILURE. Vehicle was towed to a GMC certified mechanic where it was confirmed that all Lifters and cam shaft were damaged beyond repair and must all be replaced. Estimated Cost of repairs so far: $8,596.80 Labor: Remove & Replace Left And Right Valve Lifter (Both Sides) Coolant Service Oil Change Labor Parts: Engine Camshaft 1 , Genuine GM Engine Valve Lifter Oil Manifold Gasket 1 , Genuine GM Fuel Pump Gasket 1 Engine Timing Cover Gasket Set 1 Engine Valve Lifter Guide 1 Engine Valve Lifter Guide 1 Coolant/Antifreeze Orange Dex-Cool 1 Gal 3 Engine Push Rod 8 Engine Oil Filter 1 0W-20 Full Syn 8 Engine Cylinder Head Bolt Set 1 Engine Valve Lifter Guide 1 Engine Valve Lifter Guide 1 Stock Engine Valve Lifter 4 Stock Engine Valve Lifter 4 Engine Cylinder Head Gasket Kit 1 Engine Cylinder Head Bolt 10 APPROVED Subtotal $8,422.71 + est.

Automatic emergency braking system deployed unexpectedly on acceleration from a traffic light stop. Vehicle was about 10-15 MPH and system operated with no brake pedal input. A vehicle behind had to do a panic stop to avoid collision. Deployment disengaged when accelerator pedal was released. My wife, principal driver, was in the car. She advised this had occurred two times before. No recalls are presently listed for the vehicle.
Check engine light came on. Went off a little later and then came back on. Took it to the dealership where they ran codes. They changed the fuel injector and spark plugs based on the codes listed. They heard a noise coming from under the engine and felt like it was the same failure that it happened in the 2021 to 2024 Yukon models those engines had been recalled. Was quoted $15,000 for a new engine was also charged $1000 for the fuel injector and spark plugs.
Engine lifter spring failure followed by bent valve push rod experienced on or about 11/6/2025. Engine repaired/re-built at independent auto mechanic for a total of $6,450. Parts not available but have pictures. Depending on where this incident could have occurred (freeway, long trips, while towing (boat, horses), etc.) safety concerns include being stranded in traffic or remote areas. Engine lost significant power and wouldn't have been able to tow. Engine knock warning light.

Engine failure at 114k miles required replacement.
MEMORANDUM To: National Highway Traffic Safety Administration (NHTSA) Subject: Safety Defect Report – 2019 GMC Yukon Denali 6.2L V8 (L87) with AFM/DFM I am reporting a serious and recurring safety defect involving my 2019 GMC Yukon Denali equipped with the 6.2L V8 L87 engine and GM’s AFM/DFM system. In the past twelve months, I have experienced two separate engine failures, both occurring at highway speeds and both involving valve-train/VLOM failures on the same side of the engine. In each incident, the vehicle suddenly lost power, misfired violently, and became unable to maintain speed. This created an extremely dangerous situation for my family. One failure occurred while my wife was driving; the other occurred while my [XXX] son was driving. Both were forced to maneuver across high-speed traffic with a failing engine to reach the shoulder. These events posed a clear risk of a high-speed crash, injury or even a fatality. There are hundreds—possibly thousands—of documented complaints from owners of GM vehicles with AFM/DFM-equipped engines reporting the same issues: collapsed lifters, valve failures, VLOM malfunctions, and sudden loss of propulsion. These failures often occur without warning and show a consistent pattern across multiple model years and engine variants, including the L87. The sudden loss of power at highway speeds represents a significant safety hazard. The frequency of similar reports suggests a systemic mechanical defect rather than isolated incidents. I respectfully request that NHTSA open a formal investigation into AFM/DFM-related failures in GM’s L87 and related V8 engines, with a focus on lifter, valve, and VLOM failures that lead to abrupt engine shutdown. Appropriate safety action, including a mandatory recall, should be done immediately to prevent potential injuries or fatalities. I will provide repair documentation, service reports, and other additional information. [XXX] , Esq. [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Four of the eight oil lifters in my 6.2L engine in my 2019 GMC Yukon failed. The car has around 53,000 miles. The issue was confirmed by an independent service center. There were no warning lamps or messages prior to the issue. Zero. The service center even ran diagnostics with no result and could not confirm the issue until after it partially took apart the engine. I noticed a noise similar to a card flapping in the wind and took it to the service center that same day. The car had been properly serviced with oil changes and still had 44% oil life that same day. Repairs are currently being made and estimated at $4,000.
Driving out a town 400 miles away, with a young passenger in my car on [XXX] in rush hour traffic, i started hearing a slight ticking sound then moved into a full blown knock on my drivers side ( I recorded it). within minutes, my oil light came on and my dash notification reading "engine overheating idle" with the knocking really load. I had to cross 3 lanes to traffic quickly to get to the shoulder of the road, which was NOT a safe place. I smelled smoke and cut the the engine off. I popped the hood to see that there was now no coolant (that is all I knew to look for). I immediately called OnStar Roadside assistance. 2 hours later, I was towed to a local hotel room. Car completely dead. not lights, couldn't lock it, nothing. I had to pay a large fee (almost $2k) to have my car towed back to NC from AL not to mention having rent a rental car to get us home. the car is now at a GMC dealership in Monroe NC. of course the Powertrain extended warranty doesn't cover the Battery replacement, belt replacement and water pump replacement so now I'm out of pocket $1300 just to get those install to be able to try and start the engine to further diagnose if my I have complete engine failure AND without transportation.
