On the 2021-2024 GMC Yukon 6.2L V8 (L87), the 6.2L L87 V8 in 2021-2024 Yukons can suffer catastrophic engine failure from connecting-rod bearing damage. GM's own teardown analysis (Recall 25V-274 / N252494001) identified two supplier root causes: machining sediment left on the connecting rods and in the crankshaft oil galleries, and out-of-specification crankshaft dimensions/surface finish. The bearings spin and the engine can knock, seize, or throw a rod through the block, causing sudden loss of propulsion at speed. NHTSA logged thousands of loss-of-propulsion allegations and opened an investigation into post-recall failures. Roughly 82,000 Yukons are within the affected population.
Under Recall 25V-274 GM inspects the engine; failed units get a full engine replacement (some receive GM remanufactured long blocks), and engines that pass inspection get a revised oil-fill spec switching from 0W-20 to thicker 0W-40 (GM dexos1 Gen 3), a new oil-fill cap, and a service-procedure update. Out of warranty, a rod-knock engine typically needs a complete engine or long-block replacement. Owners should have the recall performed at a GMC dealer at no charge and monitor for knocking or oil-pressure warnings.

On the 2015-2025 GMC Yukon, the power retractable running boards available on 2015+ Yukon and Yukon XL are a common failure point. The electric motors and gearboxes corrode and seize, especially in salt-belt states. Boards get stuck in the out position (creating a road-clearance hazard and trip risk) or refuse to extend. The wiring harness connections at the running board motors corrode. GM has released multiple updated motor designs, but corrosion in the mechanical linkage pins also causes binding. Repair cost is $800-2,000 per side if both motors fail.
Boards extend but don't fully retract under the truck
How to Fix
Motor replacement (GM 84085689 updated motor). Lubricate pivot points and linkage pins with marine-grade grease annually. Dielectric grease on harness connectors. Some owners disable the system and lock boards in a fixed position to avoid ongoing failures.
Owner tips & cautions
WarningRunning boards stuck in the deployed position are a safety and liability issue — the board extends into the path of pedestrians and cyclists when the doors open. If boards are stuck out, disable the system by pulling the PWRRB fuse in the underhood fuse box (varies by year — check owner's manual) to prevent accidental deployment until repaired. Do not attempt to manually force retract a stuck board as the gearbox can strip.
