Credov's researched list of the 15 faults the Toyota Corolla Fielder is known for (2006–2015), 14 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.

What to look for: Look for a 4522 recall sticker in the driver's door opening, then leave it in READY and watch for warning lights.
Why it matters: The MLIT notification states that insufficient soldering on the converter's control board can separate under repeated heat cycling, stopping the auxiliary battery from charging, illuminating warning lights and, in the worst case, shutting the hybrid system down so the vehicle cannot be driven. On a Japanese import there is no NZ owner record to notify, so an outstanding campaign follows the car into your yard.
What to look for: Listen for a slow, laboured crank or just a click when starting from stone cold, and again when hot after the drive.
Why it matters: The MLIT notification states that inadequate tightening instructions let the starter through-bolt loosen over time, shifting internal components and reducing starter output; continuing to use it can leave the engine unable to start, and repeated cranking in that state can overheat the starter with a worst-case fire. MLIT recorded 13 occurrences including two fires.
What to look for: Look for brake, ABS and skid warning lights staying on together in READY, and feel for a very heavy brake pedal.
Why it matters: Toyota Japan's notice states that frequent braking can wear the hydraulic control valve in the electric brake actuator earlier than designed, that several warning lamps then illuminate together, and that continuing to drive brings on an audible warning with higher pedal effort and reduced braking.
What to look for: Listen at cold start for the starter whirring or grinding on after the engine fires, and look for a 3344 recall sticker.
Why it matters: The MLIT notification records that the energising setting for the starter drive relay was inadequate, so silver from the contacts aggregates and flakes off; a flake caught in the circuit holds the relay energised, the starter keeps turning and in the worst case a fire results. Toyota's remedy replaces both the relay and the starter.
What to look for: Look for a 3696 recall sticker in the driver's door opening and an 'airbag not working' label on the passenger sun visor.
Why it matters: The MLIT notification records that on the single-stage passenger airbag inflator the inflator housing can rupture and scatter when the airbag deploys, causing fire or injury to occupants. The remedy is a new inflator, and where parts were short Toyota disabled the passenger airbag and labelled the visor.
What to look for: Check the airbag light comes on then goes out, and look for a 4363 recall sticker in the driver's door opening.
Why it matters: The MLIT notification records that electrical noise immunity of the airbag control unit was inadequately assessed, so noise from the vehicle's electrical components can damage an IC chip inside the unit in service and, in the worst case, deploy the airbags while the vehicle is moving. An airbag firing unprompted at speed is a crash cause in itself.
What to look for: Look for a 4174 recall sticker in the driver's door opening, or ask for the Japanese service record showing the airbag recall.
Why it matters: The MLIT notification records that handling when the igniter-charging equipment stopped was inadequate, so some inflators were filled with too little igniter material; the airbag then may not deploy properly when it operates. Toyota's remedy replaces the entire passenger airbag. These Corolla Axio and Fielder shapes are among the most common Japanese imports in New Zealand.
What to look for: Ask the importer for a Japanese recall check on the chassis number, plus the auction sheet and any recall records.
Why it matters: The MLIT recall schedules behind the Japanese campaigns cited elsewhere in this overlay all state that the manufacturer notifies vehicle users by direct mail, with trade notification through the Japanese repairers' association journal and the manufacturer's own website.
What to look for: Look for a 3055 recall sticker in the driver's door opening, and for hybrid warning lights while it sits in READY.
Why it matters: The MLIT notification records that the winding process for the inverter electric water pump coil was inadequate, so coil wire could be damaged; corrosion then breaks the wire, stopping the pump and producing a warning lamp or output-limited running, and a short between windings blows the supply fuse and leaves the car unable to be driven.
What to look for: Check the fully opened tailgate stays up on its own for 30 seconds, and look for cracks or rust on the struts.
Why it matters: The MLIT improvement-measure notification records that temperature control during the plating process was inadequate, so internal stress from plating produces microscopic cracks on the damper stay surface; the enclosed gas leaks and in the worst case the back door can no longer be held open.
What to look for: Smell around the car, especially the rear corners, for petrol after it has been filled and parked.
Why it matters: Both MLIT notifications record that the resin evaporative gas passage end is inadequate - in one case the end shape, in the other insufficient strength against fuel swelling - so cracks form in service. Continued use lets the crack penetrate, fuel leaks when the tank is full and there is a fuel smell. Petrol leaking near a hot exhaust is a fire path, and a fuel smell in a used car is often dismissed as a spill.
What to look for: Drive it cold and fully warm (20+ minutes).
Why it matters: Weak points named for this family are fluid contamination, overheating, bearing wear and seal leaks. A failing box is usually replaced with a used one in NZ. Left unrepaired this grows into a major repair bill.
What to look for: Pull the dipstick: low oil, or very black thick oil on a car with a recent service sticker, is a warning.
Why it matters: The cause is carbon-stuck or worn oil control rings, sometimes valve stem seals; it gets worse with long high-rev motorway running and stretched oil changes. Owners who never check the dipstick run it low, which then wears the chain, VVT gear and bearings. Usual NZ fix is a good used engine; a ring and seal rebuild costs more. Left unrepaired this grows into a major repair bill.
What to look for: Torch on the water pump at the belt end of the engine.
Why it matters: A seized pump can throw the drive belt. Toyota later released a modified pump (16100-09502) for ongoing leaks. An aluminium engine overheated by a failed pump can warp the head. Left unrepaired this grows into a major repair bill.
What to look for: Look around the catch in the driver's door opening for Toyota recall stickers, and photograph any numbers you find.
Why it matters: The instruction to apply a numbered sticker near the driver's door striker appears in the text of the Toyota recall notifications themselves, which makes it the one field marker a New Zealand dealer can read without a scan tool or a dealer account.
