2GR-FXE
"Engine and transmission problems seem rare — timing chain cover gasket can leak over time, and it's a huge expense to fix."
Timing Chain Cover Gasket Oil LeakHIGH
The timing chain cover gasket is a well-documented failure point on the 2GR family. The leak starts minor but worsens progressively over time and requires significant labour to access and replace due to engine positioning.
Oil Cooler Line LeaksHIGH
The oil cooler lines on early 2GR-FE/FXE engines are known to develop leaks. Community reports indicate this is a common issue on pre-facelift models around 120,000+ km. Replacement with upgraded lines is strongly recommended.
VVT-i Oil Line DeteriorationMODERATE
The rubber VVT-i oil feed line is known to degrade and leak on the 2GR engine family. Many used examples will already have had this replaced. Verify service history for this repair.
Cold Start Grinding/Rattle NoiseMODERATE
Some 2GR-equipped Highlanders exhibit an intermittent grinding or rattling noise on cold startup. This is not consistent on every start but recurs every few startups. Linked to VVT-i phaser oil pressure or idler pulley wear.
Idler Pulley WearMODERATE
Idler pulleys on early 2GR variants are noted as a known wear item in community discussions. Worn pulleys can cause belt noise and eventual belt failure if not addressed.
The 2GR-FXE in the AU30 Highlander is a fundamentally strong hybrid V6 with a good ownership reputation — catastrophic engine failures are rare and community sentiment is broadly positive. The main concerns are oil leak points (timing cover, oil cooler lines, VVT-i line) that are well-understood and fixable, though the timing cover repair is expensive due to labour. Buy with confidence if the service history shows regular oil changes and the known leak points have been addressed or show no current seepage. Budget €500–1,500 as a contingency for oil leak remediation on higher-mileage examples.
