Thanks for the intel. I'm getting 29mpg on mixed driving so far but on the more local and extra urban side (few runs above 50mph). Does make me think that maybe some cells are failing as I've been trying to make the most of engine braking and general braking too, and certainly havent been heavy footed. Feel like I should be getting 32mpg. Spark plugs were last replaced by Lexus main dealer just over 3 years ago. Does a failing 12V battery make any difference? Haven't checked tyre pressures on the 19inch wheels yet but the ride quality is absolutely shocking IMO. Constant vibration and judder with every road contour eliciting a reaction, even on the motorway. I read about the firm ride but this is kind of ridiculous. Rear bushings had an advisory so perhaps that's part of the problem there? Comfortable as the seats are, constant cabin movement grates.

Fuelly quotes in American gallons though, which would imply 36mpg in a UK setting given the 20% difference.

Hi all, Apologies that there are existing threads linked to this topic but I wanted to probe what a normal mpg return looks like on UK roads for a gen 3 RX 450h? I got a 2010 with 150k last week and whilst the car is generally very good, I have been a tad disappointed with the mpg. I've not done a long motorway run yet but on some mixed, very careful driving, I'm just about managing 30mpg. With such pronounced effort to be economical, I was hoping for 33mpg. What generally hits mpg hardest in these cars? Can a higher tyre inflation help, e.g. 40 psi? It's got 13 Lexus main dealer service stamps so surely it's well oiled and spark plugs have been changed (i know at least some have from the myLexus app). Ride is a bit choppy and suspect rear bushes have some play but keen to hear people's thoughts. Is 35mpg possible on a long motorway run with controlled speed? Thanks all...

Is inappropriately fast indicator signal self-cancelling a 'thing' on Gen 3 RX 450h's? I keep having to re-indicate, which isn't ideal.

I also seem to have this issue. I have the same box and antenna on the passenger side windscreen section. DAB radio reception is garbage. Would like to replace this unit and the copper wire as it looks ropey. Anyone know where they can be bought and/or what the part number is? Thanks

Just as an update. The dealer is replacing the transmission oil pump prior to purchase and delivery so I can't really argue with that.

There was a delay in getting me the service information as I'm buying remotely. But yes, I'm feeling very twitchy now. Hoping to speak to Lexus Ipswich later to see if they can confirm, if not I'll be calling the trade seller first thing.

Bit the bullet and buying a 2nd hand RX 450h from a trade seller. It has 13 services undertaken mainly at Lexus dealerships or Steven Eagell Toyota Dealer Group branches. That gives me some confidence but the last service spoke of a hybrid warning light being triggered by fault codes P2601, P2602, and P2603. Sounds like Lexus cleared the codes as a 1st step and quoted for a new oil pump at £1,200. Language was ambiguous but wording points towards the replacement having not happened. Should I be worried that this will rear it's head again as soon as I get the car? Can a failed pump destroy the engine? Could I be that unlucky fool who gets screwed? Have to admit I'm slightly nervous having been badly burnt on a used car recently. The RX has 150k miles and one owner from new though. Also, there is only one key. How much would a spare cost from a decent (non-dealer) auto locksmith? Thanks in advance.
