Common Issues by Make & Model

CVT seal recall — E140/E150 (2006–2008)Toyota recalled these years for a CVT rubber seal defect causing oil leaks and jerky acceleration. Always check recall status via VIN before buying a 2006–2008 Axio or Fielder.

1NZ-FE oil consumptionThe 1.5L 1NZ engine burns oil between services from around 150,000km. Check the dipstick and look for blue smoke on cold start.

Timing chain rattle — 1NZ/2ZRChains stretch at high mileage and rattle on cold start. Not immediately critical but worth negotiating on.

Sticky dash — pre-2008 E120Dashboard plastic becomes tacky in NZ heat. A $40 dash mat is the easy fix.

DPF cracking — 1KD-FTV diesel (Vigo)The diesel particulate filter on older Hiluxes can crack, especially on short-trip use. Check for DPF warning lights and ask about regeneration history.
