Steer Clear: Silverado Engines With The Most Reliability Risks
The article flags three Silverado engines as the ones to avoid: the 2014–2018 5.3L V8 with AFM, linked to excessive fuel use and lifter failures; the 2019–2024 6.2L V8 with Dynamic Fuel Management, tied to crankshaft failures and rod issues and a broad recall; and the 2007–2013 5.3L V8, which also suffered oil consumption and cam/lifter problems. It notes that AFM/DFM systems often cause issues and recommends disabling AFM/DFM if these engines are kept, otherwise avoid them.
