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.

This issue also affects: Citroën C3, Hyundai Santa Fe, Hyundai Tucson

Common Symptoms

Misfire codes P0300, P0301, P0304, P0306, P0307
Ticking or tapping from engine
Rough idle especially when cold
Check engine light
Reduced power under load
Metal shavings on oil drain plug magnet

How to Fix

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.

UpgradeGM 12639516 VLOM (Valve Lifter Oil Manifold) — mandatory replacement with lifters on all Savana AFM repairs. Commercial fleet managers frequently skip this part to save $150-200, causing the new lifter set to fail again within 30,000-50,000 miles. For fleet Savanas with frequent replacements, consider a complete AFM delete (Texas Speed TSP-AFM-DELETE kit) to eliminate the failure mode entirely. (GM OEM #12639516)

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.
NoteAFM 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.

Typical repair cost:$3,500 - $8,000

On the 1996-2025 GMC Savana, the rear cargo doors and sliding side door hinges wear out from the weight of the doors and constant commercial use. Doors sag, become difficult to close, and the weatherstripping no longer seals properly.

Common Symptoms

Doors hard to close
Wind noise from door seals
Doors sag visibly
Water leaks around doors

How to Fix

Replace door hinge pins and bushings, or complete hinge assemblies if worn beyond bushing repair. Adjust door striker plates after hinge repair. Lubricate all hinge pivot points with white lithium grease every 6 months.
