What to look out for

The checks worth doing on a Toyota Daihatsu Boon before you hand over any money. Every documented fault is listed below, each with its own page.

  • Costly issue

    Test drive and feel for rhythmic vibration during light acceleration from rest.

    See why

    CVT K110 Belt Judder on Automatic

    The Toyota Passo K110 CVT develops shudder from belt and pulley wear on urban short-trip examples. Toyota CVTF FE specification must be used — incorrect fluid accelerates belt degradation.

    What you would notice

    • Rhythmic shudder or buzz during light acceleration from rest
    • CVT fluid darker than the correct clear pink Toyota CVTF FE specification

    Typically $600–$3,500 to put right.

  • Costly issue

    Check oil level and note consumption rate.

    See why

    1KR-FE Valve Stem Seal Oil Consumption

    The Toyota Passo KGC10/KGC30 1KR-FE 1.0 engine consumes oil from worn valve stem seals on high-mileage examples, producing blue smoke from the exhaust on startup after an overnight park. The small oil capacity of the 1KR-FE means even moderate valve stem seal leakage causes noticeable oil level drops between services.

    What you would notice

    • Blue smoke from exhaust on startup and deceleration
    • Frequent oil top-ups needed between regular service intervals

    Typically $500–$1,500 to put right.

  • Costly issue

    Inspect the boot for splitting.

    See why

    Front Lower Arm Ball Joint Wear

    Front lower arm ball joints wear causing clunking and handling imprecision.

    What you would notice

    • Clunking from front suspension over bumps
    • Imprecise handling feel when cornering

    Typically $250–$600 to put right.

  • Costly issue

    Check for pulling under braking.

    See why

    Brake Caliper Guide Pin Seizure

    Front brake caliper guide pins seize from corrosion causing uneven pad wear.

    What you would notice

    • Vehicle pulling to one side under braking
    • One front disc hotter than the other after moderate use

    Typically $150–$500 to put right.

  • Costly issue

    Scan for EPS fault codes.

    See why

    Electric Power Steering Column Motor Failure

    EPS column motor fails causing sudden or gradual loss of power assistance.

    What you would notice

    • Sudden loss of power steering with EPS warning light
    • Heavy steering requiring effort especially at low speeds

    Typically $600–$2,000 to put right.

  • Common issue

    Turn the steering wheel slowly from lock to lock — clunking at the same steering angle indicates worn top mount bearings.

    See why

    Front Strut Top Mount Bearing Clunking

    Front strut top mount bearings wear causing clunking when turning the steering wheel on this small car.

    What you would notice

    • Clunking from front struts when turning or over bumps
    • Clunking repeatable at the same steering angle each sweep

    Typically $250–$600 to put right.
