Driving our 2024 Suburban, 6.2 L engine, on a 2-lane highway in southern Utah, traveling on cruise control at 70 mph, felt 2 hesitations (jerking movement), and turned off cruise control. Immediately after, heard knocking/thumping sound in the front of the vehicle, followed by a whining sound that got louder. Immediately found a turn-off from the highway, pulled in, and engine died while vehicle was still in motion. Attempted starting again and would not start.

In researching this issue, we came across NHTSA's investigation case…

While driving down a two-lane blacktop road at 70 MPH (the posted speed limit) the engine, a 6.2 L L87 with a little over 15,000 miles, grenaded and seized. At the time I recall a warning message that said something like "engine shutdown". Fortunately the electronic transmission self-shifted into neutral so the car could coast to a stop. Had it not done this a loss of control would have been likely at this speed. The vehicle was towed to the local Chevrolet dealer in Bozeman, Montana (Resseler Chevrolet) where it was confirmed the next day the engine had seized. The dealer is currently replacing the seized engine with a replacement long block. The dealership currently has the engine and is…
