2022 BUICK ENCORE

Typical onset: 60,000-100,000 mi

Symptoms: Excessive oil consumption (1 qt per 1,000 mi or worse), Loud knocking/ticking from engine block, especially on cold starts, Check engine light with misfire codes or low oil pressure, Metal shavings in oil filter during service, Sudden loss of power, engine seizing

Fix: This engine suffers from inadequate piston ring sealing and bearing clearance issues that lead to oil burning and eventual rod/main bearing failure. Once internal damage starts, a short block replacement or complete engine rebuild is the only fix. Expect 18-24 labor hours for short block swap, more for full teardown and rebuild. Many shops just source a reman long block.

Estimated cost: $5,500-8,500

Typical onset: 50,000-90,000 mi

Symptoms: Transmission fluid puddles under vehicle (red/brown fluid), Low transmission fluid warning light, Harsh or delayed shifts if fluid level drops significantly, Visible wetness along cooler lines near radiator

Fix: The crimp-style fittings on the transmission cooler lines corrode and weep, especially in salt-belt states. Lines run from transmission to radiator-mounted cooler. Replacement involves dropping undertray, removing lines, and refilling/bleeding transmission. About 2.5-3.5 hours labor plus fluid.

Estimated cost: $400-700

Typical onset: 60,000-100,000 mi

Symptoms: Loud clunk when shifting from Park to Drive or Reverse, Excessive engine rocking during acceleration, Vibration felt through shifter or center console, Visible rubber deterioration or fluid leaking from mount

Fix: The hydraulic transmission mount fails, allowing excessive drivetrain movement. Requires supporting the transmission, removing the old mount, and installing OEM or aftermarket replacement. Straightforward job, about 1.5-2 hours labor.

Estimated cost: $250-450

Typical onset: 70,000-110,000 mi

Symptoms: Rattling noise from engine bay on cold start that fades as engine warms, Loss of boost/power under acceleration, Check engine light with underboost or overboost codes (P0299, P0234), Hissing or whistling sounds under load

Fix: The wastegate actuator arm wears and rattles, eventually sticking or failing completely. Turbo replacement or rebuild required. Turbo sits low and behind the engine; removal involves loosening motor mounts and tilting powertrain. 6-8 hours labor, parts vary wildly (aftermarket vs. OEM vs. reman).

Estimated cost: $1,800-3,200

Typical onset: 40,000-80,000 mi

Symptoms: Oil leaking from valve cover or intake manifold gaskets, Rough idle or stumbling at low RPM, Oil in intake tubing or throttle body, Check engine light with lean/rich codes

Fix: The 1.4T uses an integrated PCV system in the valve cover that clogs with sludge, causing crankcase pressure buildup and oil leaks. Valve cover replacement (includes integrated PCV) plus intake manifold gasket is the fix. About 3-4 hours labor. Do NOT skip this — it accelerates the oil consumption problem.

Estimated cost: $600-950

Typical onset: 100,000 mi (service interval)

Symptoms: No symptoms until failure — this is preventive, If belt breaks: immediate engine shutdown, no restart, bent valves

Fix: This is an interference engine with a timing BELT (not chain). GM interval is 97,500 mi but many techs recommend 80k-90k given belt age and heat cycles. Always replace water pump, tensioner, and idler pulleys at same time. 5-6 hours labor. Skipping this service risks a $6k+ engine rebuild.

Estimated cost: $800-1,200
