Frequently Asked Questions
What fails on used Highlanders?▼
Very little: the V6's water pump seal weeps with age ($500–$1,200 fixed properly), and early cars can still carry the rubber oil-cooler line that should be swapped for the metal update ($250–$700). Both are visible on a lift in minutes.
Is a high-mileage Highlander safe to buy?▼
With records, yes — the 3.5 V6 is one of the most durable engines in any family SUV. Confirm the water pump has been done (or price it in) and check the oil-cooler line material, and 150k miles is a starting point, not an ending.
