2022 CHEVROLET BLAZER

Typical onset: 40,000-80,000 mi

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

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

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

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

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

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
