2022 SUBARU LEGACY XT

Typical onset: 40,000-80,000 mi

Symptoms: metallic knocking or rattling from engine bay especially when cold, oil consumption exceeding 1 qt per 1,000 miles, loss of power under boost, Check Engine Light with misfire codes, catastrophic failure: sudden loss of oil pressure, seizing

Fix: Complete short block replacement or engine rebuild required — connecting rod bearings and piston ring land failures are most common culprits. 18-25 labor hours for short block swap at dealer, 25-35 hours for full rebuild with machine work. Often covered under powertrain warranty if under 60k/5yr, otherwise catastrophic cost.

Estimated cost: $8,000-14,000

Typical onset: 50,000-90,000 mi

Symptoms: transmission overheating warnings on dash, shuddering or slipping during acceleration, burnt smell from under hood, reduced power/limp mode in hot weather or under load, CVT fluid contamination visible (milky or dark)

Fix: External CVT oil cooler develops internal leaks or blockages, causing fluid temps to spike. Requires cooler replacement, full CVT fluid flush, and often new transmission mount due to related shuddering. 4-6 hours labor plus parts.

Estimated cost: $1,200-2,200

Typical onset: 60,000-100,000 mi

Symptoms: external oil seepage visible on cylinder head mating surfaces, slight coolant smell from engine bay, minor coolant loss without visible leaks, white residue around head bolt areas, failed pressure test

Fix: While not the catastrophic head gasket failures of EJ engines, FA24 can develop external seepage requiring head gasket replacement on one or both banks. 12-16 hours labor for both sides, includes head resurfacing. Must be caught early before coolant contamination damages bearings.

Estimated cost: $2,800-4,500

Typical onset: 40,000-70,000 mi

Symptoms: clunking when shifting from Park to Drive/Reverse, excessive vibration at idle in Drive, visible sagging or tearing of rubber mount, harsh engagement under throttle

Fix: CVT transmission mount fails prematurely, likely due to weight and torque of turbo setup. Simple replacement, 1.5-2 hours labor. Often done alongside CVT cooler work.

Estimated cost: $350-600

Typical onset: 50,000-90,000 mi

Symptoms: rough idle or stumbling under boost, P0087 (fuel rail pressure too low) code, hesitation during hard acceleration, long crank/hard start when hot, fuel smell in cabin or engine bay

Fix: Direct injection fuel pump, high-pressure fuel filter, or injector seals can fail. Diagnosis requires fuel pressure testing under load. Filter replacement 1 hour, pump 3-4 hours, injector seals 4-6 hours depending on scope.

Estimated cost: $600-2,500

Typical onset: 30,000-60,000 mi

Symptoms: rattling noise on cold start that disappears when warm, noise most noticeable at idle, no performance loss, sound originates from turbo area driver side

Fix: Wastegate actuator arm develops play causing audible rattle. Often a warranty claim item. If out of warranty, replacement turbo or actuator rebuild required, 5-7 hours labor.

Estimated cost: $1,800-3,200
