Build my inspection planToyota Highlander · frequently asked questions
Is the Toyota Highlander reliable?
Very — it's among the most dependable three-row SUVs, with only minor issues to check.
Which engine is best?
The 3.5L V6 is strong and proven; the hybrid is also very reliable and efficient.
What should I check on a used Highlander?
Service history, oil level, and infotainment operation.
How often does the AWD transfer box require servicing?
The all-wheel-drive transfer box and rear differential fluids should ideally be replaced every 30,000 miles, despite some schedules suggesting longer intervals. Neglecting this can lead to premature wear of the viscous coupling or differential bearings. Always ensure the correct API GL-5 gear oil is used to prevent drivetrain binding.
Are there any concerns with the timing chain on the 3.5L V6?
The 3.5L V6 utilises a robust timing chain rather than a belt, which is generally maintenance-free for the life of the vehicle. However, the timing chain cover is prone to minor oil seepage. While rarely severe enough to cause dripping, it is a labour-intensive reseal if it worsens.
Can the XU50 Highlander tow heavy loads safely?
The 3.5L V6 models boast a maximum towing capacity of 2,268 kg when fitted with the factory towing preparation package, which includes an upgraded radiator and heavy-duty alternator. Hybrid variants are restricted to 1,587 kg. Always verify the V5C and check for aftermarket tow bars lacking necessary cooling upgrades.
