If you have error message on dash showing check system with the yellow tyre logo, most likely one of your tyre pressure sensor is faulty.....or out of battery.

You could drive it into your Lexus dealership and get it fixed, my local Lexus want £100 which I am not prepared to pay. The sensor is only around £20 and if you shop around I am sure you can get it cheaper. Get a local tyre shop to swap it over and you save a lot of money. Unfortunately it is a bit more complex than that as each sensor have its own ID code and you need to match that with your ECU.

This video will show you how, what needed and if it is worth doing it yourself

Lexus GS450h is now one of my all time favourite car. The only problem is the small boot space, it have to accommodate the hybrid battery, apart from that it tick all my boxes. 300+ BHP, average 25MPG in London and it is exempted from the new ULEZ charge. Super quiet and comfortable, a bit too quiet sometimes as you can hear any interior trim squeak....

adjustable suspension by a switch so you have have more spirited drive and does not feel like driving a barge.
