2022 LEXUS NX 350

Typical onset: 5,000-30,000 mi

Symptoms: Sudden loss of power or engine stalling without warning, Metallic knocking or rattling from engine bay, Low oil pressure warning light (often too late), Metal shavings or glitter visible in oil during changes, Check engine light with misfire or oil pressure codes

Fix: Complete engine replacement or short block swap required. Manufacturing debris (machining remnants) blocks oil passages, starving bearings and turbo. Pistons score, rods fail, crank gets damaged. Toyota has issued TSBs and extended warranty coverage for some VINs. Dealer-only job, 18-24 hours labor for full engine R&R including calibration.

Estimated cost: $15,000-22,000

Typical onset: 20,000-50,000 mi

Symptoms: Transmission fluid spots or puddles under vehicle (pink/red fluid), Burnt transmission smell after highway driving, Transmission overheating warnings on dash, Fluid visible on cooler lines at frame rail or radiator area

Fix: Cooler lines corrode or chafe where they route near exhaust or body pinch points. Replace affected lines and flush any debris from cooler. 2-3 hours labor plus fluid refill and system relearn.

Estimated cost: $600-1,200

Typical onset: 40,000-70,000 mi

Symptoms: Clunk or thud when shifting from Park to Drive or Reverse, Excessive vibration at idle, especially with AC on, Engine/transmission movement visible when accelerating hard, Rubbing or banging noise over bumps

Fix: Rear transmission mount (torque rod) tears due to weight of 8-speed auto and turbo engine torque. Common on all TNGA-K turbo platforms. Replace mount, 1.5 hours labor. Check engine mounts at same time.

Estimated cost: $350-550

Symptoms: White smoke from exhaust after engine overheats, Coolant loss with no visible external leaks, Milky oil on dipstick or oil cap, Rough idle, misfires, or loss of power, Bubbles in coolant reservoir when engine running

Fix: Secondary failure after turbo engine catastrophic event or overheating incident. If engine survives initial debris failure but runs hot, head gasket can fail. Requires head removal, machining, new gasket set. 14-18 hours labor. Often find warped head requiring replacement.

Estimated cost: $4,500-7,000

Typical onset: 30,000-60,000 mi

Symptoms: Hard starting or extended cranking, Loss of power under acceleration, especially uphill, Engine stumbling or hesitation at part throttle, Fuel pump whine or buzzing noise from rear

Fix: In-tank filter (part of pump module) clogs from contaminated fuel or debris. Direct-injection turbo engines sensitive to fuel quality. Replace pump/filter assembly, 2.5 hours labor. Drop tank for access.

Estimated cost: $800-1,400
