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

• Serious issue

  Request full service history showing timing belt replacement with km and date.

  EF/JB Series Timing Belt Failure (Interference Engine)

  The EF and JB-series 0.66L engines used in L200, L500, and L700 Mira generations are interference designs where belt failure causes piston-to-valve contact and catastrophic engine damage. JDM imports frequently exceed the 60,000 km or 5-year replacement interval. An additional failure mode is tensioner spring fatigue, which can cause belt jump before complete breakage and is not always immediately obvious.

  What you would notice

  • Engine cranks but will not start
  • Sudden total loss of power while driving
  • Engine misfires or runs roughly after partial belt slip

  Typically $320–$520 to put right.

• Costly issue

  Check CVT fluid colour on the dipstick or via inspection plug.

  See why

  CVT Shudder and Fluid Degradation

  L700 and LA300 Mira CVT units develop shudder on light-throttle pull-away due to fluid friction modifier degradation and torque converter lockup clutch wear. Most imported examples have no CVT fluid change history from Japan. A fluid change with genuine Daihatsu CVT fluid resolves early-stage cases; advanced units require valve body reconditioning or complete replacement.

  What you would notice

  • Juddering or shuddering on take-off, especially on inclines
  • Hesitation between 20–40 km/h under gentle acceleration
  • Dark or burnt-smelling CVT fluid on inspection

  Typically $200–$3,000 to put right.

• Costly issue

  Check oil level at every fuel stop for two weeks — consumption over 500ml per 5000km is abnormal for this engine.

  See why

  KF-VE Oil Consumption from Piston Ring Flutter

  The KF-VE 0.66 three-cylinder engine is known for oil consumption from piston ring flutter on vehicles used mainly for short urban trips. The rings do not fully seat when the engine rarely reaches full operating temperature, allowing oil to pass into the combustion chamber. Blue smoke on startup and increased oil consumption are the primary symptoms.

  What you would notice

  • Blue smoke from exhaust on startup after overnight park, clearing after 30-60 seconds of running
  • Frequent need to top up engine oil between scheduled service intervals

  Typically $500–$2,000 to put right.

• Costly issue

  Check the dipstick for level and colour and ask how much oil it uses.

  See why

  Oil consumption on the little three-cylinder (EF/KF)

  The Mira's three-cylinder kei engines (older EF, newer KF) commonly develop oil consumption as valve stem seals harden and piston rings wear, burning oil and showing blue smoke on start-up. These are tiny engines in cheap, hard-used cars, so maintenance history is everything. A Mira that needs regular oil top-ups, or that puffs blue when it fires up, is telling you the rings or seals are on the way out - a big job relative to the car's value.

  What you would notice

  • Blue smoke on cold start or when accelerating
  • Oil level dropping between services
  • Oily, smoky exhaust smell

  Typically $600–$1,800 to put right.

• Costly issue

  Inspect boot for splitting.

  See why

  Front Lower Ball Joint Wear

  Front lower suspension ball joints wear on kei cars due to small-diameter joint design. Common on urban-use Mira examples.

  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.
