Long-Term Ownership and Reliability
The Toyota Fortuner is built for harsh conditions and often used for family duty and off-road driving. With proper servicing, many reach 200,000 miles or more without major faults. Diesel versions are most likely to experience injector and turbo problems, while suspension and brakes wear faster due to the vehicle’s size and weight. Rust is also a concern in older imports.
Typical annual servicing and running costs are around £500 to £750, though big jobs like gearbox rebuilds or turbo replacements can push costs higher.
Final Thoughts
The Toyota Fortuner is a strong and practical SUV that combines seven-seat capacity with true off-road ability. It is generally reliable but does face weaknesses such as injector wear, turbocharger failure, transmission issues, suspension fatigue, and rust. With routine servicing and early attention to faults, the Fortuner remains one of the toughest SUVs for family and adventure use.
Tips for buyers:
- Check service history for injector and transmission work.
- Inspect underbody and chassis for rust.
- Test drive to assess suspension and steering.
Tips for owners:
- Service engine and gearbox on schedule.
- Apply rust protection early.
- Replace suspension and brake parts before they cause wider issues.
- Budget for higher costs due to the SUV’s size and weight.
