The 2022 Chevrolet S10 is a Brazilian-market mid-size truck sold in South America with proven powertrains but known for transmission mount failures and diesel-specific fuel system issues. The 2.8L Duramax is generally more durable than the 2.5L flex-fuel gas engine, which suffers from valve train problems.
Transmission Mount Failure
Common · medium severityTypical onset: 40,000-80,000 mi
Symptoms: Clunking on acceleration or deceleration, Vibration felt through shifter and floor, Excessive drivetrain movement visible during throttle blips
Fix: Replace transmission mount assembly, typically 1.5-2.5 hours labor. Often find engine mounts also worn at same interval, so inspect thoroughly. OEM mounts last longer than aftermarket in this application.
Estimated cost: $250-450
Lifter and Camshaft Failure (2.5L Flex Engine)
Occasional · high severityTypical onset: 60,000-120,000 mi
Symptoms: Ticking or tapping noise from valve cover area, especially cold start, Check engine light with misfire codes, Loss of power and rough idle, Metal shavings in oil during changes
Fix: Requires cylinder head removal, lifter replacement (all 16), and often camshaft replacement due to lobe wear. 12-16 hours labor. Caused by inadequate oil pressure to lifters combined with ethanol fuel degrading oil faster. Always replace cam if more than two lifters are collapsed.
Estimated cost: $2,800-4,500
Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Red fluid spots under vehicle front section, Burning smell after highway driving, Transmission running hotter than normal, Low transmission fluid on dipstick
Fix: Lines corrode at crimp points and rubber hoses crack from heat cycling. Replace both pressure and return lines as a pair, 2-3 hours labor. Flush cooler if contamination is present. Check radiator-mounted cooler for internal leaks (fluid mixing) while you're there.
Estimated cost: $350-650
Diesel Fuel Filter Clogging and Injector Issues (2.8L Duramax)
Occasional · high severitySymptoms: Hard starting, especially in cold weather, Loss of power under load, Rough idle and white smoke from exhaust, Fuel system pressure codes
Fix: Poor fuel quality in some markets causes premature filter clogging and injector fouling. Replace fuel filter every 10,000 mi preventively, not the 20,000 mi spec. If injectors are affected, cleaning usually doesn't work—expect replacement at $400-600 each plus 6-8 hours labor for all four.
Estimated cost: $2,000-3,500
Head Gasket Failure (2.5L Flex Engine)
Occasional · high severityTypical onset: 80,000-140,000 mi
Symptoms: Coolant loss with no visible leaks, White smoke from exhaust on startup, Overheating under load, Bubbling in coolant reservoir, Oil milky or frothy on dipstick
Fix: Multi-layer steel gasket fails between cylinders or into coolant jackets. Requires head removal, pressure test, and resurface if warped (common). 10-14 hours labor. Always check for cylinder head cracks during resurface—this engine runs hot with ethanol blends. Replace thermostat and water pump at same time.
Estimated cost: $2,200-3,800
Harmonic Balancer Separation
Rare · high severityTypical onset: 100,000-150,000 mi
Symptoms: Severe vibration at idle that increases with RPM, Squealing from serpentine belt area, Visible wobble of crankshaft pulley, Check engine light with crankshaft position sensor codes
Fix: Rubber isolator separates from outer ring due to heat and age. If it grenades, you risk timing cover damage and belt wrapping around crank snout. Replace immediately when wobble is detected, 2-3 hours labor. Inspect timing cover for cracks and replace crank sensor while apart.
Estimated cost: $450-750
The 2.8L Duramax version is the better buy if maintained properly; avoid high-mileage 2.5L flex engines unless valve train has been rebuilt—transmission mount replacement is a given on any used example.
