The 2022 Colorado ZR2 is too new for widespread pattern failures, but early diesel models show concerning engine durability issues while the 3.6L V6 remains relatively trouble-free. Off-road abuse accelerates transmission mount and cooler failures.
2.8L Duramax Catastrophic Engine Failure
Occasional · high severity
Typical onset: 30,000-80,000 mi
Symptoms: excessive oil consumption before failure, metallic knocking from crankcase, loss of power under load, check engine light with low oil pressure codes
Fix: Complete engine replacement or rebuild required. Connecting rod bearing failures lead to spun bearings, scored crankshafts, and piston damage. Short block replacement is 24-30 hours labor, full rebuild adds another 8-12 hours for machine work coordination and assembly.
Estimated cost: $8,500-15,000
Transmission Oil Cooler Line Failure
Common · high severity
Typical onset: 40,000-70,000 mi
Symptoms: transmission fluid leaking near radiator, overheating transmission temps, burnt fluid smell, slipping shifts when hot
Fix: Cooler lines corrode at frame contact points or crack from chassis flex during off-roading. Replace both lines preventatively when one fails. 2.5-4 hours labor depending on 4WD component removal needed.
Estimated cost: $600-1,200
Transmission Mount Deterioration
Common · medium severity
Typical onset: 35,000-60,000 mi
Symptoms: clunking when shifting from park to drive, excessive vibration at idle, visible torn rubber on mount inspection, transmission movement during acceleration
Fix: Factory mount rubber separates from bracket, especially on trucks that see trail use or heavy towing. Mount replacement is straightforward but requires transmission support. 1.5-2.5 hours labor.
Estimated cost: $350-650
Diesel Fuel Filter Premature Clogging
Occasional · medium severity
Symptoms: hard starting when cold, loss of power on acceleration, rough idle, fuel system fault codes
Fix: Poor fuel quality or water contamination clogs filter well before scheduled interval. Some trucks need filter changes every 10,000-15,000 mi instead of factory 22,500 mi. Includes priming procedure, 0.8-1.2 hours labor.
Estimated cost: $180-320
Diesel Piston Ring Failure Leading to Blow-by
Rare · high severity
Typical onset: 50,000-90,000 mi
Symptoms: excessive crankcase pressure, oil consumption over 1 quart per 1,000 miles, blue smoke on startup, oil in intake system
Fix: Ring land cracks or ring flutter causes blow-by and oil consumption. Requires engine disassembly, new pistons and rings, cylinder honing. In-chassis overhaul is 28-35 hours, engine removal adds 6-8 hours.
Estimated cost: $7,000-12,000
3.6L V6 Head Gasket Seepage
Rare · low severity
Typical onset: 60,000-100,000 mi
Symptoms: slight coolant smell from exhaust, minor coolant loss with no visible leaks, white residue on spark plugs, pressure test shows slow leak
Fix: V6 models occasionally develop external head gasket seepage rather than catastrophic failure. Both heads should be done together. 10-14 hours labor including coolant flush and new plugs.
Estimated cost: $2,800-4,200
Owner tips
Diesel owners: send oil samples to Blackstone Labs every 5,000 miles to catch bearing wear early—$30 analysis can save a $12,000 engine
Change transmission fluid at 50,000 miles regardless of factory schedule if you tow or off-road regularly
Inspect transmission cooler lines annually for corrosion at frame contact points, especially in salt-belt states
Diesel fuel filter changes every 12,000-15,000 miles prevent injector issues, use only top-tier fuel stations
Buy the 3.6L V6 without hesitation; avoid the 2.8L Duramax unless you can verify oil consumption history and bearing condition through analysis—these engines are grenading at unacceptable rates for a 2022 model year.

Maintenance Schedule — 2022 Chevrolet Colorado ZR2
General Motors, LLC (GM) is recalling certain 2022 GMC Canyon and Chevrolet Colorado vehicles equipped with a manual passenger seat. The front passenger seat may have a hook attachment that was not properly welded, allowing it to separate from the inboard track of the seat frame.
Consequence: An improperly welded seat frame may not properly restrain the seat occupant, increasing the risk of injury in a crash.
Remedy: Dealers will inspect the front passenger seat and replace the cushion frame, if necessary, free of charge. Owner notification letters were mailed July 6, 2022. Owners may contact GMC customer service at 1-800-462-8782 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N222368320.
