2022 TOYOTA PRIUS

Typical onset: 60,000-120,000 mi

Symptoms: Excessive oil consumption (1+ quart per 1,000 mi), Rod knock or bottom-end rattle, especially cold starts, Check engine light with low oil pressure codes (P0524, P0523), Metal shavings in oil during changes, Sudden loss of power or engine seizure

Fix: Complete engine replacement or short block R&R. Toyota has extended warranties on some units but not all 2022s qualify. Expect 18-24 labor hours for short block, 12-16 for used engine swap. Remanufactured long blocks run $4,500-6,500, used low-mileage takeouts $2,500-4,000. Check if your VIN is covered under TSB or settlement before paying out of pocket.

Estimated cost: $5,000-9,000

Typical onset: 80,000-140,000 mi

Symptoms: Pink or red fluid puddles under engine bay center, Transaxle overheating warnings on dash, Burnt transmission fluid smell, Slipping or delayed engagement in hybrid transaxle

Fix: The auxiliary cooler lines or the cooler itself crack at fittings. Requires removal of under-covers and sometimes inverter shield. 2-3 labor hours for lines, 3-4 if cooler body is leaking. OEM cooler assembly is $400-600, lines $150-250. Flush and refill CVT fluid adds 1 hour and $120-180 in fluid/filter.

Estimated cost: $600-1,200

Typical onset: 70,000-110,000 mi

Symptoms: Clunk or thud when accelerating from stop, Vibration at idle when engine cycles on, Visible sagging or torn rubber on rear mount, Excessive engine/transaxle movement when revving in park

Fix: The rear mount (Toyota calls it transmission mount, part 12372-37050) bears hybrid system load and fails earlier than conventional mounts. Replacement is 1.5-2 hours with vehicle on lift, requires supporting transaxle. OEM mount is $180-240, aftermarket $90-140. Don't cheap out—weak mounts accelerate CVT and inverter wear.

Estimated cost: $300-500

Symptoms: Hard starting or extended cranking, especially after sitting, Engine stumble or hesitation under load, Check engine light with fuel trim codes (P0171, P0174), Rough running when gas engine kicks in

Fix: PHEV models driven primarily on electric can accumulate varnish/sediment in fuel system. In-tank pump/filter assembly replacement requires dropping fuel tank—4-5 labor hours. OEM pump module $500-700. On 2022s still under warranty (36k/3yr bumper-to-bumper), push Toyota to cover this as 'defect in materials.' If out of warranty, use Top Tier fuel and add stabilizer if car sits weeks at a time.

Estimated cost: $900-1,400

Symptoms: Engine shuts off unexpectedly at low speeds or idle, Hybrid system warning light with no stored codes, Loss of power steering and brake assist during stall, Intermittent 'Check Hybrid System' message

Fix: Covered under NHTSA recall 22V-842 (ECM software). Dealer reflash takes 1 hour, no parts cost. If your VIN wasn't included but you experience these symptoms, demand TSB 0200-22 update—some units were missed in initial campaigns. This is a free fix; don't let a dealer charge diag time if recall applies.

Estimated cost: $0 (recall)

Typical onset: 50,000-90,000 mi

Symptoms: White smoke from exhaust on startup, Coolant loss with no external leaks, Milky or frothy oil on dipstick/cap, Overheating under load or AC use, Bubbles in coolant reservoir when running

Fix: Often a consequence of overheating from oil starvation (see piston ring problem). Head gasket job on 2ZR-FXE is 10-12 hours—must disconnect hybrid battery, remove intake/exhaust, timing chain. OEM gasket set $200-350, machine shop resurface $150-250. If motor has rod knock or excessive blowby, don't bother—engine needs replacement. If caught early, $2,200-3,500 total.

Estimated cost: $2,200-3,500
