2013 BUICK ENCORE

Typical onset: 60,000-120,000 mi

Symptoms: Excessive oil consumption (1 qt per 1,000 mi or worse), Loud knocking or ticking from engine block, Metal shavings in oil, milky oil cap residue, Check engine light with misfire codes or low oil pressure warning, Sudden loss of power or catastrophic seizure

Fix: Complete engine replacement or rebuild required. Piston ring land failures and spun bearings are common failure modes on these Ecotec engines, often traced to PCV system issues causing carbon buildup and oil starvation. Short block replacement takes 18-24 labor hours; used engines from salvage yards are common but risky given fleet-wide issues.

Estimated cost: $4,500-7,500

Typical onset: 70,000-110,000 mi

Symptoms: Transmission fluid puddles under vehicle (red or brown fluid), Burnt transmission fluid smell, Harsh or delayed shifting, especially when cold, Transmission overheating warning on dash, Coolant contamination with ATF (strawberry milkshake in overflow tank)

Fix: The external cooler lines corrode and leak, but worse is when the internal radiator cooler fails, mixing coolant and ATF. Requires transmission oil cooler replacement, lines, flush, and often transmission rebuild if coolant contamination occurred. Line replacement alone is 2-3 hours; full contamination repair 8-12 hours with transmission R&R.

Estimated cost: $800-1,200 (lines only), $3,500-5,000 (contamination damage)

Typical onset: 50,000-90,000 mi

Symptoms: Clunking noise when shifting from Park to Drive or Reverse, Excessive vibration at idle, especially with AC on, Visible engine movement when revving in Park, Thud felt through floorboard during acceleration

Fix: The upper torque strut mount (dogbone mount) and side transmission mount wear prematurely. Rubber separates from metal, allowing excessive engine movement. Requires lifting engine slightly for access. 2-3 labor hours for both mounts.

Estimated cost: $400-700

Typical onset: 60,000-100,000 mi

Symptoms: Rattling noise from engine bay on cold start (first 30 seconds), Loss of boost pressure, sluggish acceleration, Check engine light with underboost codes (P0299), Whistling or whooshing sounds under acceleration, Blue smoke from exhaust (if seals fail)

Fix: Wastegate actuator rod wears and rattles; eventually wastegate sticks open causing underboost. Turbo replacement required in most cases, though some shops attempt actuator replacement. Turbo R&R requires removing exhaust manifold and various heat shields. 6-8 labor hours.

Estimated cost: $1,800-2,800

Typical onset: 40,000-80,000 mi

Symptoms: Rough idle and misfires when cold, Reduced fuel economy (3-5 mpg drop), Hesitation or stumble during light acceleration, Check engine light with multiple misfire codes, Excessive oil consumption begins suddenly

Fix: Direct-injection engines with no port injection suffer intake valve carbon buildup. PCV valve and hoses fail, worsening oil consumption. Requires walnut blasting intake valves (head stays on, intake manifold removed) and PCV system overhaul. 5-7 labor hours for proper cleaning.

Estimated cost: $600-1,000

Typical onset: 60,000-100,000 mi

Symptoms: Coolant seepage around thermostat housing (front of engine), Low coolant warning light, Sweet smell from engine bay, Overheating in severe cases, Visible orange coolant residue on engine block

Fix: Plastic thermostat housing and coolant outlet crack or warp. Requires replacement with updated metal parts if available. Housing is buried under intake components. 3-4 labor hours including coolant system flush and bleed.

Estimated cost: $500-800

Typical onset: 50,000-90,000 mi

Symptoms: Check engine light with EVAP large leak code (P0455), Difficulty filling fuel tank (pump clicks off repeatedly), Rough idle after refueling, Hard starting or long crank times, especially when hot, Fuel smell near rear of vehicle

Fix: Purge valve and vent valve fail commonly; fuel pump experiences reduced pressure over time. EVAP repairs take 1-2 hours; fuel pump requires dropping tank, 3-4 hours labor.

Estimated cost: $300-500 (EVAP), $700-1,100 (fuel pump)
