SlashGear Flags 3 Chevrolet Silverado Engines From 2007-2024 Over Reliability Failures

Summary
Three Silverado engine families drew the warning: the 2007-2013 5.3L V8, 2014-2018 5.3L V8, and 2019-2024 6.2L V8, all cited for recurring failure patterns.
The common thread is GM’s fuel-management hardware—AFM in the older 5.3L trucks and DFM in newer models—which owners link to excessive oil consumption, lifter and cam failures, and eventual engine damage.
For 2014-2018 trucks, CarComplaints and NHTSA reports point especially to the 2014 model year, where AFM-related oil burn and lifter failures can escalate into full engine failure.
For 2021-2024 6.2L V8 Silverados, the concerns extend beyond DFM: the L87 engine was hit by a broad recall over crankshaft and connecting-rod defects, with reports of knocking and bearing problems preceding major failures.
The report says other Silverado options—notably the 4.3L V6 and 6.0L V8—draw fewer complaints, and suggests the flagged engines are safer bets only if the fuel-management system has been permanently disabled.
