The 2022 Blazer shares GM's C1 platform with the Acadia and XT5, bringing typical crossover reliability with some notable exceptions. The 2.0L turbo and 3.6L V6 variants show distinct problem patterns, with transmission cooling and turbo 4-cylinder internal failures being the primary concerns.
Symptoms: Excessive oil consumption (quart per 1,000 mi or worse), Metallic knocking or ticking from engine bay, Loss of power under acceleration, Check engine light with misfire or low oil pressure codes, Blue smoke from exhaust on startup
Fix: This is catastrophic when it happens. The 2.0L LSY turbo suffers from piston ring land failures and bearing wear, likely tied to carbon buildup and aggressive tune from the factory. Repair requires complete engine rebuild or short block replacement. 18-24 labor hours for R&R and internal work. Many shops recommend replacing with reman long block rather than attempting rebuild.
Estimated cost: $7,500-12,000
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 30,000-70,000 mi
Symptoms: Transmission fluid puddles under vehicle, typically passenger side, Burnt transmission fluid smell, Erratic shifting or slipping when fluid runs low, Pink/red fluid visible along cooler lines near radiator
Fix: The quick-connect fittings on the 9-speed transmission cooler lines corrode and leak, especially in salt states. Lines themselves can also crack at mounting points due to vibration. Replace both pressure and return lines as a set with updated fittings. 2-3 labor hours including fluid refill and relearn procedure.
Estimated cost: $450-750
9-Speed Transmission Harsh Shifts and Shudder
Common · medium severity
Typical onset: 20,000-60,000 mi
Symptoms: Hard downshifts when coming to a stop, Shudder or judder during 2-3 or 3-4 upshift under light throttle, Delayed engagement from park to drive, Hesitation when accelerating from a roll
Fix: GM's 9T50 transmission has adaptive learning issues and torque converter clutch shudder. Start with fluid flush using genuine Dexron ULV and TCM software update (most recent calibration addresses shift quality). If shudder persists, torque converter replacement required. Software update: 1 hour. Torque converter: 8-10 hours.
Estimated cost: $300-400 for flush/update, $2,200-3,200 for torque converter
Transmission Mount Failure
Occasional · low severity
Typical onset: 50,000-90,000 mi
Symptoms: Clunking when shifting from reverse to drive, Vibration through floor at idle in drive, Excessive driveline movement visible when accelerating/braking, Metallic banging over bumps
Fix: The front transmission mount tears, allowing excessive powertrain movement. Common on V6 models due to extra torque. Inspection from below shows visible separation or fluid leaking from hydraulic mount. Straightforward replacement. 1.5-2 labor hours.
Estimated cost: $250-400
Fuel System Clogging (Particularly 2.0L Turbo)
Occasional · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: Hard starting after sitting overnight, Stumble or hesitation during acceleration, Check engine light with fuel trim or pressure codes, Rough idle when engine warm
Fix: Carbon buildup in direct-injection system and fuel filter clogging cause drivability issues. The in-tank filter element isn't serviceable by design, but aftermarket versions exist. Start with fuel system cleaning and injector service. If pressure issues persist, fuel pump module or tank-internal filter requires attention. Injector cleaning: 2 hours. Pump module: 3-4 hours.
Estimated cost: $400-600 for cleaning, $800-1,200 for pump module
Infotainment System Freezes and Restarts
Occasional · low severity
Symptoms: Black screen on startup requiring several minutes to boot, Random system restarts while driving, Backup camera intermittently not displaying, Android Auto/Apple CarPlay disconnecting repeatedly, Climate controls unresponsive through touchscreen
Fix: GM's Infotainment 3 system has software stability issues. Most cases resolved with full system update at dealer level (requires GM subscription access for latest calibration). Hard reset procedure: hold power and home buttons for 45 seconds. Persistent failures may need radio module replacement. Software update: 0.5 hours. Module replacement: 1.5 hours.
Estimated cost: $150-250 for update at dealer, $800-1,200 for module replacement
Owner tips
If buying the 2.0L turbo, verify oil consumption history and request compression test—walk away from any engine using more than 1 qt per 3,000 mi
Check transmission fluid condition and color at pre-purchase inspection; dark brown or burnt smell indicates previous overheating or deferred maintenance
Ensure all software updates have been performed, particularly transmission and infotainment calibrations—many early issues resolved through programming
Inspect transmission cooler lines and fittings for seepage during routine service; catch leaks early before causing trans damage
Skip the 2.0L turbo unless under powertrain warranty; the 3.6L V6 is more durable but expect transmission annoyances—solid transportation if priced right, but not exceptional long-term value.
