Common Problems & Known Issues

The 2016 Express is built on GM's ancient but proven full-size van platform—solid bones, but showing its age with aging fuel system components, transmission cooling issues, and AFM-related engine problems on V8s. Work vans rack up miles fast, so expect higher-mileage maintenance earlier than typical passenger vehicles.

Active Fuel Management (AFM) Lifter Failure on 6.0L V8

Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Ticking/tapping noise from engine at idle that worsens when warm, Check engine light with P0300-series misfire codes or P0521 oil pressure, Lifter collapse causing valve train damage, Metal shavings in oil on filter inspection
Fix: Requires disabling AFM system and replacing affected lifters, camshaft if damaged, and sometimes valve springs. Range AFM Delete kit plus lifter replacement is 12-16 hours labor. If cam is damaged, add another 6-8 hours. Many shops now proactively disable AFM on these engines.
Estimated cost: $2,800-5,500

Transmission Oil Cooler Line Failure

Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Transmission fluid leaking from front of vehicle near radiator, Pink/red fluid puddles under engine bay, Transmission overheating warnings or limp mode, Coolant mixing with transmission fluid (strawberry milkshake fluid)
Fix: Steel cooler lines rust through where they connect to radiator or at frame mounting points. Requires replacement of affected lines, often both for preventive measure. If internal radiator cooler failed and contaminated fluid, trans needs full flush or rebuild. Line replacement alone is 2-3 hours labor.
Estimated cost: $400-800 for lines only, $2,500-4,500 if transmission contaminated

Fuel Pump and Fuel Filter Housing Corrosion

Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Hard starting after sitting, especially in cold weather, Loss of power under acceleration or uphill, Engine stalling at idle or when hot, Fuel smell from rear of vehicle
Fix: In-tank fuel pump assemblies corrode, especially in rust-belt regions or with ethanol fuel. Pump replacement requires dropping tank (3-4 hours). Fuel filter housing on frame rail also rusts through on 6.0L models. Filter housing replacement adds 1-2 hours.
Estimated cost: $600-1,200

Intake Manifold Gasket Leak (V8 engines)

Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Coolant loss with no visible external leak, White smoke from exhaust on cold start, Rough idle or misfire when engine is cold, Coolant smell from engine bay
Fix: Plastic intake manifolds develop cracks or gasket failures allowing coolant into cylinders. Requires intake manifold removal and gasket replacement, about 4-6 hours labor. Often find corroded coolant crossover passages that need cleaning or replacement.
Estimated cost: $800-1,400

EVAP Vent Solenoid and Purge Valve Failure

Occasional · low severity
Typical onset: 50,000-100,000 mi
Symptoms: Check engine light with P0449, P0496, P0455 codes, Fuel smell near rear of vehicle, Difficulty fueling (pump clicks off repeatedly), Failed emissions test
Fix: EVAP vent valve on top of fuel tank corrodes or sticks. Purge valve on engine also fails. Vent valve requires dropping tank or accessing from inside van (2-3 hours). Purge valve is easier, 0.5-1 hour. Often both need replacement at similar intervals.
Estimated cost: $300-700

Rear Leaf Spring and Shackle Corrosion

Occasional · medium severity
Typical onset: null
Symptoms: Sagging rear end, especially when loaded, Clunking noise over bumps from rear suspension, Visible rust on leaf springs or shackles, Uneven tire wear on rear wheels
Fix: Heavy cargo use and road salt cause leaf spring main leafs to crack and shackles to seize or break. Replacement requires removing U-bolts and shackles, often cutting rusted hardware. Per side is 3-4 hours if bolts come out clean, 5-6 hours with rust. Always inspect frame mounts—cracked frames are not uncommon on high-mileage cargo vans.
Estimated cost: $800-1,600 per side
Owner tips
  • If buying a 6.0L V8, budget immediately for an AFM disable kit—it's cheap insurance against $4,000+ engine work
  • Inspect transmission cooler lines annually in rust-belt states; replace proactively at 80k miles to avoid contamination
  • Check frame and leaf spring mounts carefully on cargo vans—cracks here mean walk away
  • Use Top Tier fuel and replace fuel filter every 30k miles to extend fuel pump life
  • Flush transmission fluid every 50k miles on work vans—these transmissions run hot and don't tolerate abuse
Solid work van if maintained, but AFM lifters on 6.0L V8 and transmission cooler issues are expensive time bombs—buy one with those already addressed or budget $3k-5k for the eventual repairs.
