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 severity
Typical 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 severity
Typical 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 severity
Typical 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 severity
Typical 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 severity
Typical 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 severity
Typical 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
Owner tips
Change CVT fluid every 30,000 miles despite Toyota's 'lifetime fill' claim—critical for oil cooler longevity
Use only 0W-16 full synthetic oil and keep intervals at 5,000 miles max for the turbo engine
Inspect transmission mount at every oil change after 30k miles—early catch prevents CVT damage
Avoid lugging the engine below 1,500 RPM under load; the small turbo needs revs to stay healthy
Check coolant level monthly—small cooling system has no reserve capacity for leaks
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.
