Toyota 2GR-FE engine: known problems

2GR-FE engines built up to around April 2008 use a rubber-section VVT-i oil supply hose that perishes and can split, draining engine oil in as little as 30 seconds and risking catastrophic engine damage. Toyota superseded it with a solid metal line on late-2008/2009-onward engines.

Built within the affected 2007-2008 window, TRD Aurions can carry the same perishable rubber VVT-i oil hose that splits and drains oil in seconds.

Rubber section of the VVT-i oil supply line bursts causing rapid total oil loss. Engine failure if not noticed immediately. Affects 2GR-FE across Camry, Aurion, RAV4, Kluger.

Like the 2GR-FE in many Toyotas, the rubber section of the VVT-i oil supply line can perish and develop a pinhole leak, dumping oil - in the worst case onto hot exhaust, a documented fire risk.

The 2GR-FE water pump can weep coolant from the weep hole/seal with age and km, eventually dripping under the car.

The six-speed U660E auto commonly flares (sharp RPM rise) on the 3-4 upshift in the first ~10 minutes after a cold start, and develops a lock-up shudder at light/moderate throttle around 60-90km/h. Usually caused by deteriorated/incorrect fluid and valve-body/lock-up solenoid wear; Toyota released a revised valve body to address it.

The Eaton TVS supercharger needs its own oil and a healthy supercharger/intercooler belt, pulley, idler and coupler; neglected examples can whine, leak or shed belts. TRD-specific parts are scarce now that TRD Australia is long gone.

400Nm through the front wheels produces strong torque steer and chews front tyres, CV joints and bushes faster than the standard Aurion, particularly if driven hard.

Higher-mileage 2GR-FE V6s can start consuming oil between services. Usually a monitoring/top-up issue rather than catastrophic, but worth checking on a high-km example.

The 3.5L's accessory idler pulley bearing wears and squeals (often noticeably with the A/C running); a seizing pulley can throw the belt and, if neglected, has been linked to under-bonnet fires.

200kW through the front wheels produces pronounced torque steer under hard acceleration and accelerates front tyre wear, especially on the firmer-suspension Sportivo/SX6 grades. Not a fault.

Water pump bearing wears.

Throttle body builds up carbon causing rough idle.

XU50 cars use the updated all-metal VVT-i oil line (Toyota switched away from the failure-prone rubber line in 2010), so the dramatic rubber-line rupture is not the XU50 risk it was on older V6s - but front timing-cover and cam-cover gasket seepage still appears at higher km.

A brief rattle on cold start can indicate a tired cam chain tensioner.

A brief top-end rattle at cold start, as if there's no oil pressure, from the VVT-i cam phasers/oil control - usually harmless but worth monitoring with clean oil and correct service intervals.
