General Motors introduced the LM2 Duramax 3.0L inline-6 turbo-diesel engine in 2019. It marked GM's entry into the light-duty diesel market, aiming to compete with Ford's Power Stroke and Ram's EcoDiesel offerings. Designed for efficiency and refinement, the LM2 employs advanced technologies like aluminum block construction and a variable geometry turbocharger. It’s found in popular vehicles like the Chevrolet Silverado 1500, GMC Sierra 1500, and the Chevrolet Tahoe/Suburban and GMC Yukon/Yukon XL SUVs. A common question revolves around the engine’s longevity and durability, particularly given its relatively recent introduction to the market. Some reported issues include fuel system problems, emissions system malfunctions, and occasional sensor failures.
