Known problems on the Toyota Harrier XU30
2.4 2AZ-FE burns oil
Costly if missed
2005–2013 · 2AZ-FE · petrol · Engine
What to look for: Check the dipstick: low oil on a car that was 'just serviced' is a warning.
Why it matters: Toyota ran an extended warranty in the US for engines using more than about a litre per 1,900 km, affecting around 1.7 million engines, so it is a known design fault rather than abuse. Symptoms usually start from about 70,000-80,000 km. Fix is new pistons and rings (expensive) or a used engine; better oil only slows it. Applies to the Harrier 240G and other 2AZ cars.
What to look for: Look at the front of the engine below the pump pulley for dried pink crust or wet coolant, and at the coolant.
Why it matters: Leaks have been reported from as early as about 40,000 km (a 2017 Kluger at 39,000 km, a 2007 RX350 at 40,000 miles) and are common past 100,000 km. A slow weep becomes a steady loss, the coolant level drops and the engine can overheat. Low-use cars seem prone to it. Left unrepaired this grows into a major repair bill.
