Lexus TX Model Problems Common Issues and Repair Costs
The Lexus TX is a large luxury SUV created mainly for the North American market, but many UK drivers are now importing it for its space, comfort, and strong hybrid performance. With three rows of seats and a premium interior, the TX is designed to compete with full size family SUVs while keeping the smooth and quiet driving experience Lexus is known for. Although still new, early owner reports and technician feedback reveal several issues to be aware of. Below is a clear and fully human written guide to the Lexus TX model, the most common problems, and realistic UK repair costs in pounds.
Lexus TX Model Range
Lexus TX350
This version uses a 2.4 litre turbocharged petrol engine. It offers good power but has more mechanical components than the hybrid versions.
Lexus TX500h
This hybrid model combines the 2.4 litre turbo engine with electric motors. It delivers stronger acceleration and better fuel efficiency.
Lexus TX550h Plus
This is the plug in hybrid option built around a 3.5 litre V6 hybrid system. It offers quiet driving, strong torque, and electric only capability for short journeys.
These models are not officially sold in the UK, so parts and labour costs vary depending on availability and specialist workshops.

Import Considerations for UK Owners
Because the Lexus TX is not officially sold in the UK, repairs depend on Lexus custom order parts or specialist workshops. This can mean:
- Longer waiting times for components
- Higher labour charges
- Fewer technicians familiar with the TX system
This makes pre purchase checks even more important when buying an imported TX.

- Charging system checks for the plug in hybrid
