The Lexus dealership I use replaces the batteries in both keys on every service. And as these batteries only cost pence, then one can always replace them oneself every six months (if one wishes) just for peace of mind. Think of it as 'preventive maintenance!'

I think you'll find that the clue is, Robert lives in Perthshire!

I look forward to reading of your results - - I've oft wondered how effective it can be

Hi Jag, I had a Catloc fitted (by our Lexus dealership), (for there had been a few cat.s disappear in our locale too), and so far, so good. However, you're right that there is not a guaranteed method of protecting one's cat, although I believe the two important cat.s on your car are beneath the bonnet, and the unit underneath the car is less critical - (that's the unit protected by the Catloc)

Andrew, whilst I'm not in the market for tyres, I think you would help a response if you gave more information: Size of tyres Make / model of tyres Age/wear?

My experience is that whilst I only get about a 5% improvement in mpg using premium fuel, (or, now, E10 with a fuel additive), I feel more comfortable hoping that the claimed additive ingredients counter some of the possible adverse effects of E10. And I've convinced myself that the engine is smoother, - (it isn't of course, but I'd like to think so!) Most importantly, - my mpg has improved over the few years I've had the RX, not because of magic, but I've learned how to drive it more efficiently in different road/traffic conditions. It helps that I'm never in a scalding rush to get anywhere!

Rob, the 3rd Generation RX450's don't suffer from canbus thefts.

I will normally achieve between 25<>30,000 miles on a set of tyres. (both for the Lexus and the previous MB S500) Always use decent tyres (current M.. X Climates), previously Continental on the MB) I check my tyre pressures every 3<>4 weeks, (and drive gently), but read a report a few months ago (and cannot remember the source), that over 50% of drivers drive on under-inflated tyres)

As others have said, I would still invest in having your car wheel alignment (all 4 wheels) check - but search locally for a reputable specialist to do it, Kwik Fit may well be the first in the classroom to put their hand up with "Please Sir, we can do it Sir", but one would be better served by a specialist that takes real care with your set-up.

And you're the only person whom has reported this!!!!!

I bought a set of Lexus blades (front and rear) for our RX450 for £36.50 from Lexus Direct (though there is an additional postage cost) . but in the grand scheme of things, I'd rather have wiper blades I know I can rely on (I prefer to see where I'm going! 😉 )

Even better, try PTFE powder (Amazon) an extremely fine powder, (basically Teflon), it won't attract dirt as a silicone liquid spray. (also great for all plastic<>plastic rubbing surfaces, internal car trim squeaks) and clothes zips, curtain tracks etc

Now....... At what point do you discover that you've mislaid the fixing 'buttons'?

Have you changed the battery in the key ? Have you a second key?
