The Toyota Raize (co-developed with and built by Daihatsu as the Rocky) is generally a mechanically solid small crossover, but it has a few known quirks, maintenance sensitivities, and historical recalls.
1.
Engine & Drivetrain Issues
- 3-Cylinder Engine Vibration: Both the 1.0L Turbo (1KR-VET) and 1.2L naturally
aspirated (WA-VE) engines are 3-cylinders. They produce noticeable idling
vibration and a rougher noise profile compared to 4-cylinder engines. While
this is a characteristic of the engine design rather than a defect, worn
engine mounts over time can make it much more pronounced.
- D-CVT Hesitation & Maintenance Sensitivity: The Dual-Mode CVT uses both a belt and a split-gear
drive. While efficient, owners report occasional rubber-band response or
lag when stepping hard on the accelerator. Neglecting transmission fluid
changes can lead to gear engagement delays, shuddering, or early wear.
- Prevention:
Flush or replace the CVT fluid every 40,000–50,000 km, especially in
stop-and-go heavy city driving.
- Turbo Sensitivity (1.0L Models): The turbocharger relies heavily on regular oil
maintenance. Skipping oil changes or using incorrect oil grades can lead
to sludge buildup and early turbo wear.
2.
Known Recalls & Electrical / Mechanical Quirks
- e-Smart Hybrid ECU Recall (2021–2022 Models): Early production Raize Hybrids had a recall related to
the hybrid control unit (ECU). A software fault could cause the petrol
generator engine to stall unexpectedly while driving.
- Smart Key & Start-Stop Button Glitches: Some owners report intermittent issues with keyless
entry recognition or the push-start button failing to engage on the first
press, often resolved with a fresh key fob battery or switch cleaning.
- Suspension Bushing & Steering Rack Noise: Clunking or squeaking noises when turning at low
speeds or reversing often trace back to dry front control arm bushings or
steering rack wear over uneven roads.
3.
Build Quality & Comfort Complaints
- Cabin Noise Insulation (NVH): Wind noise at high speeds (above 90–100 km/h) and
engine noise entering the cabin are widely cited complaints due to lighter
sound-deadening materials.
- Firm Ride & Suspension Bounce: Because of its short wheelbase and lightweight
platform, the rear suspension can feel stiff or bouncy over bumps and
unpaved roads.
- Interior Plastics:
High-touch areas use hard plastics that can scratch easily or develop
minor cabin rattles over time.
Summary
Checklist for Buyers
- Check Service History: Ensure oil changes were done on time (every
5,000–10,000 km) and that CVT fluid was serviced around 50,000 km.
- Test Drive Check:
Shift between Reverse and Drive on an incline to check for instant
engagement, and listen for front suspension knocks during low-speed
maneuvers.
- VIN Scan: Verify if any outstanding Daihatsu/Toyota safety recalls (such as the hybrid ECU reprogram) apply to the vehicle.
