Long Term Ownership and Reliability

The Toyota 4Runner is one of the longest lasting SUVs, with many examples running well past 200,000 miles. However, as most UK 4Runners are imports, parts availability and labour costs can be higher. Annual servicing and routine repairs average between £500 and £700, but owners should budget extra for suspension work and rust protection.

Final Thoughts

The Toyota 4Runner is a capable, tough SUV that often outlives its competitors, but it comes with some problem areas. Rust is the biggest long term concern, while transmission and head gasket repairs can be costly. Preventive maintenance, rust protection, and regular servicing will keep ownership costs under control.

Advice for buyers:

  • Inspect the frame closely for rust.
  • Test the transmission for smooth shifting.
  • Check service history for major engine work.

Advice for owners:

  • Stay up to date with fluid changes and rust protection.
  • Inspect suspension and brakes regularly.
  • Budget for higher running costs compared with smaller Toyota models.
