I have been extremely disappointed with the fuel consumption of this car, and complaining to Lexus, ever since I bought it in 2009. I had moved on from a RX400h which had an official EU figure of 34.1 mpg and in practice actually easily achieved slightly over 30 mpg. Lexus are claiming 44.8 mpg for the RX450h and I foolishly had expected to achieve a figure of at least 39 mpg. In practice, with extremely carefull driving, the best I could obtain was 34mpg. Lexus firstly tried to reset the electronics and then replaced the battery, but with no improvement. They then told me that I was alone in having this problem and it must be caused by my driving style! I felt I was alone in having this problem until I read the Honest John website. According to, at the last count ,over 360 other drivers, 34mpg is a good average for this car! Lexus are still strongly pushing their mileage figure in National advertising (The Times 6.2.13 - two full page adverts). I think they are miss-selling and have submitted a complaint to the Advertising Standards Authority. The problem is that the EU figures are misleading They take no account of the differences between these figures and those actually achieved in practice, in respect of individul models. If anyone else feels as strongly as i do, perhaps we could take the matter further.

Hello folks. Wondering if someone can help me. I recently purchased a 2004 S type. The car was advertised as being in good condition apart from the slight tapping noise. I emailed the seller who advised that the noise went away after a while. Picked up the car and to be honest everything worked perfectly apart from the tapping noise. I took it to my local garage and the as soon as he heard the sound told me the pistons have gone and I would need a new engine. Well that was a shocker. I decided to get a second opinion and went to the local Jaguar dealer who also said the same thing. Contacted the guy I bought it off who told me he had done some investigation and quote " the engine tapping and pistons do not make that noise when you get a piston go you get a missfire and smoke,ive been told its either a big end tapping in that case you need new shells,or a hyd tappet sized and would need a new one,deff not a piston as the car wasnt misfiring,or smoking"

Also wanted to add there is a lot of oil leaking on the underside

Now all this sounds alien to me. I have told the guy I want my money back, but I must admit I do like the car and have thought about changing the engine. What would you folks suggest.

Appreciate any help/advice.

Thanks

I have just been outside to put my car away in the garage and as i got in i noticed a car setting off in front of me with no rear tails lights showing.I flashed him to let him know he didn't have his lights on.A bit further up my road he did a u-turn and came back towards me.At this point he seemed to have his lights on.As he passed me i looked round and found the back of his car in darkness.I then looked at the plate of the car and noticed it was 2012.My guess was that he had daytime running lights on at the front and because he could see his lights had thought that his lights were already on but obviously no tail lights.

This begs the question is why don't cars fitted with DRL's also have auto lights so there is no confusion.
In fact why don't all modern cars have auto lights?
We have all these gadgets like adjustable wingmirrors and see you home lights but for the sake of a few quid i think that all cars,especially those with drl's,should have auto lights.

The amount of drivers who forget to put their lights on is quite high round where i live.

What does everyone else think especially if drl's are fitted.
(Also i feel cars with drl's should also have the tail lights illuminated so part of the above problem wouldn't happen) Read more

Hi

For the past couple of weeks when the temperatures have been at or below around 4 degrees I'll start the car from cold, it will fire up, make a feeble attempt at idling then just die. Then i'll start it up again but this time the car will put the glow plug light on first, then make a much better job of starting, even though it will be idling roughly for a few minutes.... Read more
