On the 2010-2025 GMC Savana, gMC Savana vans equipped with 4.8L (L20), 5.3L (LM7), and 6.0L (L96) V8 engines with Active Fuel Management suffer the same AFM lifter collapse problem documented across the entire GM full-size truck/van lineup. The collapsible AFM lifters on deactivation cylinders fail between 60,000-120,000 miles, causing misfires, engine ticking, rough idle, and potential engine damage. Commercial Savana vans used for fleet operations are especially vulnerable due to high mileage accumulation and variable maintenance practices. The problem affects all GMT600 platform Savana/Express vans with AFM-equipped engines.
Replace all 16 lifters and VLOM (GM 12639516). AFM delete kit for permanent fix. Range Technology RA003B disabler for prevention. Increase oil change frequency to 5,000 miles with Dexos2 full synthetic for commercial use vans.
Owner tips & cautions
TipCommercial fleet Savanas should have the oil changed every 5,000 miles with full synthetic Dexos2 regardless of the GM oil life monitor. The monitor was calibrated for personal-use duty cycles, not the sustained highway loads typical of delivery or passenger van service. Fleet data shows AFM lifter failure rates double on vans maintaining the GM oil life monitor interval vs fixed 5,000-mile synthetic changes in commercial service.
WarningAFM lifter failure on a Savana loaded with passengers or cargo is a safety situation — if the engine goes into limp mode or loses significant power while loaded and moving in traffic, the driver has reduced ability to merge, accelerate, or climb grades safely. For commercial operator fleets, it is strongly recommended to install a Range Technology AFM disabler (RA003B) on every Savana at fleet intake — the $300 device prevents a potential $6,000 repair and avoids unexpected breakdowns during revenue service.
