you must have a fitted a flat battery by mistake or fitted it upside down?

Double DOH!  I took the Battery out and then noticed there was a little sticker on the one side.  Took it off, same Battery back in, hey fing presto! ☺️

I just did an experiment.  I used the working fob to open the car, then put it at the back of the house, out of range. Then I got in the car with the non responsive one and tried to start the car.  The car said 'Key not detected', but when I put it by the power button, it started.  Got back out and couldn't lock the car with it.  

Holding down the open button for thirty seconds didn't work unfortunately.

I was changing the Battery and left it too long, now it doesn't work. Can I get it going again? 

Lexus replaced all four trailing arms on my Gen IV before selling it to me.  Their internal invoice priced the job at £2400.

engine problem - unlikely, spark plugs may need to be replaced
Incorrect tire pressure. unbalanced wheels, as written above.
there may also be wear on the suspension or steering, and vibration can also be transmitted to the steering wheel

It exactly matches the feel/sound of engine when accelerating from slow speeds and pulling off. 

I haven't got a clue what it could be. 

I don't know what it could be. 

I'm going to get the wheels balanced and a four wheel alignment to see if that makes any difference. 

As I accelerate from slow speeds the vibration matches the sound I can hear. The engine noise in my RX is louder in the cabin than I expected. 

To feel vibration in the steering wheel from the engine? 

Mine are still on back order, supposedly.

I've been a bit surprised by how noisy the engine can be.  Under acceleration it sounds quite growly. I'm used to cvt gears so I know it's not that sound. 

Even my wife commented on it being louder than expected. 

This is just from cold, so will be noisier anyway. I'll have to get a recording of it under acceleration.

You may find this hard to believe but unless specifically requested the slide pins are generally not removed and re-greased during a dealer brake service.This often results in the Lexus seized calliper problem which I strongly suspect is the cause here.

The only specific parts of a brake calliper alone that can seize are the pistons and the pad slides as these are the only moving parts in it, the only other moving parts are the slide pins…. the usual cause.

I have never heard of any 4 pot callipers seizing up the reason probably being that these do not have slide pins.

Do you have any other symptoms like juddering brakes or pulling to one side?

Wow! My local guy would clean and regrease as a matter of course when doing a brake service on my cars. 

No, all seems otherwise fine.

I'll get onto the dealers today. If they did the sliders when they checked / serviced the brakes then why would it be causing a problem so soon? 

Rather than start a new thread, can someone tell me or point me in the way of how to change the unlock feature on the remote from open the driver door to open all doors?

On the lower photo that you posted you can see evidence of excess heat damage due to the caliper binding. 

Do you mean the colour?

Looks more like the pad is at fault. 

Who fitted the pads and discs?

Main dealers, when I bought the car in December.

The thing is, that soon after I bought the car I was looking through all the service print outs and noticed that the service they did just before I bought the car  said there was very uneven wear between the two rear sets of pads. 2mm/7mm iirc.  They only replaced the discs and pads. The service sheet stated possible caliper fault, but they didn't replace it.  I contacted their service department and they said that 'calipers were within tolerance.'  

I'm just being very aware, that the further it gets from me having purchased the car, the harder it'll be to get them to replace it if it is faulty.

Brand new discs and pads put on in October.  One is doing a full, even sweep of the disc, but the other seems to be applying more pressure and only to the main central part of the disc.

The shiny disc was slightly warm after driving for a few miles, while the other was cold.

Everyone think the caliper is f#[]#[[?

The windscreen is supposed to be heated isn't it?  It's the Premier model, so has almost everything.

It's loud even on the lowest setting, like you'd expect if it was on the highest. 

The cabin takes longer to warm up than I expected. 

Bought a Series IV RX 450h.

The fan seem very loud, even at minimum setting.  The car takes longer to demist and longer to warm up than I expected.

Two questions:

Does this model tend to make a lot of noise when the blowers are turned on?  

Could the condenser be knackered causing the other symptoms?

I know the steering is speed and angle sensitive, but it just seems too heavy, for example, at 15mph on roundabouts, the difference is big, even running 39 psi.  It doesn't lighten up until the steering is totally straight.

They said that they would have automatically checked the alignment and wouldn't be itemised on the bill, so fair enough.

I's a Gen IV.  The dealership replaced trailing arms before I bought it to get it through the MOT, but there is no evidence of them doing an alignment.  The tyres are more worn on the edges.  I've got a copy of their internal invoice and it doesn't state that it's been done.  Perhaps it was OK but I'm going to speak to the sevice manager today as their own workshop recommended a caliper replacement two years ago with the previous owner but they didn't get it done, just replaced the discs and pads.  It had pads again the last service due to uneven wear with a comment suggesting a caliper fault yet it wasn't replaced.

This dealership was great a few years ago when I used them last, but the new owners have spoilt the Lexus experience for me.

I'm at the dealers on Thursday so I'll ask to drive another Mark I to compare.

No

Have you checked the tyre pressure?

I've inflated them up to 39 psi, and obviously it's better, but still seems heavy. Take into account that this is a new car to me. 

What psi do most people run? 

Does the RX450h steering feel quite heavy? 

I've got a 2016 Premier Plus with 20" wheels.  Can anyone point me towards a space saving wheel for this?
