Hi Aleksandrs,

The most common fault with the RX 400h, as with any hybrid, is that the fuel economy won't be half as good as you think it will. The last RX model we tested returned just 29mpg overall, a figure we've equalled in both a Land Rover Discovery 3.0 diesel and a Porsche 911 Carrera 4S!

That apart, they're incredibly solidly built, as are pretty much all Lexus models. The high-tech in-car entertainment system, with its touch-screen controller, can throw up an occasional glitch but the only other serious concern lies in the hybrid electric drivetrain. Generally, it's totally reliable but we have heard of an occasional one having an AC/DC power convertor fail, which is a massively expensive job to fix if it does go wrong. As we say, it seems to be an isolated problem but one worth bearing in mind.

Let us know how you get on
