- 60,000 miles: The water pump may start to leak. This is a common issue on many Toyota models, and the 2018 Highlander is no exception.
- 100,000 miles: The spark plugs are due for replacement at this mileage. Some owners have also reported issues with the fuel pump at this mileage. The timing chain should be inspected for any signs of stretching or wear.
