New owner of RX400h

[acer54]

I have just purchased a 2008 RX400h with 118,000 miles on the clock, are their any known issues that I should look at and check with this particular model.

Any suggestions would be gratefully appreciated.

Hi Steve

Check for water ingress in the rear light clusters and boot.

If you have a sunroof then it is worth opening it and pouring water around the edge cutter and make sure it drains away and comes out underneath the vehicle.

Also check the underside for corrosion and possibly consider added extra underseal.

Check that the cam belt was changed at 100,000 miles.

Thanks for the info, I will check all of these points this week.

Cambelt has been changed.

Has anyone had any issues with the hybrid system, this is the first hybrid I've had and was wondering if their was any potential problems I should know about?

[ColinBarber]

There was an inverter recall which you should check has been done (I'm sure it has). I've heard of one or two inverter issues and one or two rear motor issues. No other issues directly related to the hybrid system, but Battery issues caused by water damage have also been reported.

Nothing that you can really do about this, other than possibly consider a used Lexus warranty.

Check for corrosion on the rear discs---usually a sign that the calliper slide pins are sticking

"possibly consider added extra underseal."

Does anyone have an opinion on undersealing?

I'm told my car has quite a lot of surface rust underneath... ( though not a safety issue ).

Not underseal but I get a local garage to have a good go round with Waxoyl on both my Lexus/Lexus's/Lexus'/Lexi. Japanese cars do have that probably now unfounded reputation but for the 30 quid I think it costs me I think it's worth doing.
