Credov's researched list of the 5 faults the Toyota ist is known for (2005–2012), 4 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: Feel for movement or a knock when you push and pull the steering wheel up, down and side to side.
Why it matters: The MLIT notification records that the bracket fixing the steering column under the instrument panel was insufficiently strong, so repeatedly turning the wheel hard to full lock cracks it; continuing to use the car spreads the crack until, in the worst case, the steering column can no longer be held in place.
What to look for: Feel the driver's window switch for warmth after working every window several times, and smell for hot plastic.
Why it matters: The MLIT notification records that the method of applying lubricating grease to the switch was inadequate, leaving some switches short of grease; wear particles from the sliding terminals combined with moisture form a short circuit, the terminal heats, the switch and surrounding plastic burn and in the worst case a fire results.
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 leaves or standing water under the bonnet below the windscreen, and check all wiper speeds and brake lights work.
Why it matters: MLIT notification No. 3343 records that the drain shape at the wiper motor mounting is inadequate, so if leaves and debris are not removed the drain blocks; overflowing water then enters the motor and the wiring for items such as the brake lamps, and in the worst case the wipers or brake lamps stop working. Corroded wiring found later is an expensive and awkward repair, and non-working brake lights fail a warrant.
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.
