Common Problems & Known Issues

The 2019 Encore with the 1.4L turbo is a compact GM crossover built on the Gamma II platform. While convenient and efficient, this powertrain combination has notable weaknesses in engine longevity and transmission cooling that sharply escalate repair costs past 80,000 miles.

1.4L Turbo Catastrophic Engine Failure (Piston Ring Land / Bore Wear)

Occasional · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Excessive oil consumption (1 qt per 1,000 mi or worse), Blue smoke on startup or acceleration, Low compression, misfires, rough idle, Check engine light with P0300-series codes
Fix: Common failure mode is piston ring land fracture and cylinder bore scoring. Requires short block replacement or full engine rebuild. 12-16 labor hours for short block swap, more for complete rebuild. Often totals the vehicle given low resale value.
Estimated cost: $4,500-7,500

Automatic Transmission Oil Cooler Line Leaks / Cooler Failure

Common · medium severity
Typical onset: 60,000-90,000 mi
Symptoms: Transmission fluid pooling under vehicle (pink/red fluid), Transmission overheating warnings or limp mode, Burnt transmission fluid smell, Erratic shifting or slipping after highway driving
Fix: Cooler lines corrode at fittings or cooler itself develops pinhole leaks. Replacement involves trans cooler, lines, and full fluid flush. 3-5 labor hours depending on access and corrosion severity.
Estimated cost: $600-1,200

Transmission Torque Mount Failure

Common · low severity
Typical onset: 50,000-80,000 mi
Symptoms: Clunking or banging when shifting from Park to Drive/Reverse, Excessive vibration at idle in Drive, Visible engine movement when revving in Park, Metallic rattling over bumps
Fix: Upper transmission mount (torque strut) rubber deteriorates. Straightforward replacement, 1.5-2 labor hours. OEM mount recommended over aftermarket for longevity.
Estimated cost: $250-450

Turbocharger Wastegate Rattle and Boost Control Issues

Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Rattling sound from engine bay on cold starts (first 30 seconds), Loss of power, sluggish acceleration, Check engine light with P0299 (turbo underboost), Turbo whistle or whine pitch changes
Fix: Wastegate actuator linkage wears or wastegate flapper sticks. Turbo replacement required; no rebuild kits hold up. 6-8 labor hours including coolant/oil line work and intercooler pipe removal.
Estimated cost: $1,800-2,800

Fuel Injector Carbon Buildup and Direct Injection Coking

Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Rough idle, stumbling on light throttle, Misfires on cold start, Reduced fuel economy (2-3 mpg drop), Check engine light with fuel trim or misfire codes
Fix: Direct injection engines lack port fuel to clean intake valves. Requires walnut blasting of intake valves and injector cleaning or replacement. 4-6 labor hours for valve cleaning, intake manifold removal.
Estimated cost: $500-900

PCV System and Intake Manifold Oil Contamination

Occasional · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Oil in intake tubing or throttle body, Rough idle, stalling at stops, Increased oil consumption without external leaks, Check engine light with P0171/P0174 (lean codes)
Fix: PCV valve and internal separator get clogged, pressurizing crankcase and pushing oil into intake. Replace PCV valve, clean intake manifold and throttle body. 2-3 labor hours.
Estimated cost: $300-550
Owner tips
  • Monitor oil level obsessively—check every 500 miles after 60,000 mi; catch consumption early before piston damage
  • Change transmission fluid at 50,000 mi (not lifetime fluid despite GM claims); use Dexron VI/ULV only
  • Use Top Tier gasoline and periodic fuel system cleaner to reduce direct-injection carbon buildup
  • Inspect transmission cooler lines annually for seepage once past 50,000 mi—catch leaks before trans overheats
Buy only with full service records showing oil top-ups and early trans fluid changes; budget $2,000-3,000 for deferred powertrain issues on higher-mileage examples—engine failure risk makes this a gamble past 80,000 miles.
