The 2022 Toyota Raize is a compact SUV built on the Daihatsu platform with a small-displacement turbo engine. While generally reliable for its class, the 1.0L turbo sees issues typical of small forced-induction motors under city-driving stress, and the CVT transmission has known weak points in cooling and mounting.
CVT Transmission Oil Cooler Failure
Common · high severityTypical onset: 40,000-70,000 mi
Symptoms: Transmission overheating warning light, Burning smell from transmission area, Delayed engagement or shuddering during acceleration, CVT fluid degradation on inspection
Fix: Replace transmission oil cooler and flush contaminated CVT fluid. Requires removing front bumper and radiator support in most cases. 4-6 hours labor depending on cooler line corrosion.
Estimated cost: $800-1,400
Transmission Mount Premature Wear
Common · medium severityTypical onset: 30,000-60,000 mi
Symptoms: Clunking on acceleration or deceleration, Excessive vibration at idle in Drive, Visible transmission sag on lift inspection
Fix: Replace transmission mount assembly. The OEM mount rubber separates early, especially in hot climates or with frequent stop-and-go driving. 1.5-2 hours labor.
Estimated cost: $250-450
1.0L Turbo Timing Chain Stretch and Tensioner Failure
Occasional · high severityTypical onset: 60,000-90,000 mi
Symptoms: Rattling on cold start that persists 5-10 seconds, Check engine light with VVT timing codes (P0011/P0021), Loss of power under load, Metallic ticking at idle
Fix: Replace timing chain, tensioner, guides, and VVT sprockets. Common on 1KR-VET engines with extended oil change intervals or low-quality oil. 8-10 hours labor for full timing service.
Estimated cost: $1,800-2,800
Hydraulic Valve Lifter Noise and Wear
Occasional · medium severityTypical onset: 50,000-80,000 mi
Symptoms: Persistent tapping noise from valve cover, especially on startup, Noise increases with engine temperature, Oil consumption may increase slightly
Fix: Replace hydraulic lifters (all 12 on the 1.0L turbo). Often done during timing chain service if already in there. Lifters alone: 5-6 hours. Combined with timing work saves 2-3 hours overlap.
Estimated cost: $900-1,500
Turbocharger Wastegate Actuator Sticking
Occasional · medium severityTypical onset: 70,000-100,000 mi
Symptoms: Overboost or underboost codes (P0234/P0299), Lack of power on acceleration, Intermittent boost delivery, Hissing or fluttering under load
Fix: Clean or replace wastegate actuator. Carbon buildup common on short-trip vehicles. If actuator arm is seized, full turbo replacement required. Clean/adjust: 2-3 hours. Replace turbo: 6-8 hours.
Estimated cost: $400-2,200
Head Gasket Seepage (1.0L Turbo)
Rare · high severityTypical onset: 80,000-120,000 mi
Symptoms: Oil weeping from cylinder head/block mating surface, White smoke on cold start that clears, Coolant loss with no visible external leak, Compression test shows cross-leak between cylinders
Fix: Head gasket replacement with cylinder head resurfacing. Common if engine was overheated due to CVT cooler failure or low coolant. Requires timing chain removal. 10-14 hours labor.
Estimated cost: $2,500-4,000
Solid city runabout if maintained aggressively, but the CVT cooling issues and turbo engine sensitivity make it a higher-maintenance choice than naturally-aspirated Toyotas—buy only with full service records and budget for the 60k timing/lifter job.
