Long-Term Ownership and Reliability
The Toyota Land Cruiser 300 is designed to survive tough conditions, with many expected to pass 200,000 miles if serviced properly. However, the move to twin-turbo V6 engines and hybrid systems adds complexity and cost. Suspension and brakes wear faster due to the SUV’s size and weight, while electronic and sensor faults can be expensive to diagnose.
On average, annual servicing and running costs are around £600 to £850, but major work such as turbo or transmission rebuilds can raise costs significantly.
Final Thoughts
The Toyota Land Cruiser 300 is one of the toughest SUVs in the world, offering luxury, off-road ability, and long-term dependability. While it is not free of faults, issues like injector wear, turbo failure, suspension fatigue, and electrical problems can be managed with regular servicing. Hybrid models add efficiency but bring the risk of expensive battery repairs.
Tips for buyers:
- Check service history carefully for injectors and gearbox work.
- Inspect suspension and brakes for wear.
- Look underbody for early signs of rust.
Tips for owners:
- Follow the service schedule, especially oil and transmission fluid changes.
- Protect the chassis with rustproofing.
- Deal with suspension and brake wear early.
- Budget for higher repair costs on hybrid versions.
