John if you have had tyres fitted at Lexus and they loosing pressure take it back and get them to sort it,they will Im not sure of the Hybrid system but round town you should get good MPG Motoway you will be useing the full 3.5 engine so yu will use a bit of fuel im sure someone with the hybrid 450h will chime in and tell you the fuel figures you could probably get a tin of injector cleaner and put it in with yr petrol im sure you must have used it at sometime also just starting car and checking this and that will make it use more fuel Start again just drive it like you would like to drive it and see the end result after say a fortnight but dont forget it is a heavy car with a big engine and lots of electric goodies on if the battery is a bit down the altenator will be going full blast which is a fuel user also air con but in the final analysys if lexus as fitted tyres for you and loosing air they should put it right i run mine at 33 all round 450 will be different as regards to the transmission mine changes seamlessly i cant tell it changes unless i look at the rev counter good luck robert

Hi John I think you are reading too much into it my car runs superb i get 33 mpg on runs regualy granted mine is gs300 round town around 27 ive had the car 2 years now and apart from servicing costs cost me nothing i feel totaly happy about the realibilaty of the car and i feel a million dollars driving it All cars will sound a bit harsh if yu floor it As regards to the slowing down on hills thats the auto box doing its job not allowing the car to overrun it will feel like its holding the car back this is perfectly ok. and designed to do this Just put your paranoia on the back burner the cars are bullet proof regarding the tyres loosing pressure a tyre and wheel are what they,are same on all vehs go to the tyre specialist and get them to check them out but one point there is a way to take them of because of the TPS but they will know as they are now universal on all new cars the shuddering on the brake pedal is the abs pump bringing up the pressure just one further point the rear calipers due stick on sometimes especially if the braking as not been hard just enjoy the car granted if anything major does go wrong it can be expensive but they are ultra realiable robert

John I also agree with you on the steering i double checked mine and mine too is a bit heavy feeling and also does sometimes pull to left on camber roads but i am completely happy with it on the motorway its as straight as a die. If you read the old report /review of the GS that is one of the points it brings up not being able to throw it round corners like the BMW. I am sure that once you get yr new tyres run in it will be perfect. I drove my Sons OMEGA and his steering was a lot lighter than mine but a bit more wooly at least the LExus as a solid feel to it and i am quite happy with my steering The point to make is make sure yu use a tyre specialist for alignment as Lexus dealers dont have those 4 wheel alignment machines Enjoy the car they are fabulous Robert

Hi John Thats very true but some of those machines have green zones and red zone the point to make is exactly what you have found out 1 side could be in green at lower end and other at top end of green the operator may just say " all in green its ok " but may not be true the m/c may only be as good as the operator Just go back and say its a lot better but still pulling to the left and they will compensate for that if he is a good operator trust me they will want you happy you will get there I cant comment on the other points but due to the silence of these cars you can sometimes hear the various sensors and relays clicking Robert

I would think that this is an alignment problem as you say one front tyre on one side was worn that would account for it When i bought my car it had Falkens on (Ditch Finders) and rear Left was more worn than Rear Right So i went to my Friends Lads TYre fitting Garage who did a 4 Wheel alignment and he found the rear Right was toeing in a lot more than the Left which will throw the car to the kerb wearing out front Left as you compensate for pull i also had TOYO Proxes fitted at 125 a corner and they are absolutely silent and wearing well I would book the car in for 4 wheel alignment and get it done its 50 up here but most tyre specialist do it it will transform the car Hope that helps Robert

Hi I have a 55 plate gs300 the other day i was coming up to a junction when a Car transporter youve guessed it a "Walon dummy" turned straight onto road i braked hard i knew ive got that Emergency Brake System and was suprised how quick it pulled up a car behind also braked hard as i heard his tyres scream. The point im making i heard bump at back from axle as I was moving off just a second or two after pressing accelerator as though the rear brakes had been stuck on. Now i had new brakes pads and discs fitted in septeber last at lexus i asked if the calippers was ok they said yes no problem, Is this a normal action as everything works fine braking wise TIA Robert

Hi David I contacted SGS who asked to find out where it was catching the hinge and a photo if possible ,I did this and they sent me some new fittings that screwed on Exactly Like the origionals And is now working Perfect. I dont know if they will last a long time but they have 2 yr Warrantty and cost 36 each as opposed to 103 from Lexus Robert

Hi David The Struts arrived from SGS but am sorry to say that they were not quite correct the part that fits on to the ball on the left side looking into boot fouled the hinge only slightly but fouled it just the same , it eventualy came off. the end looks larger than the OEM however on the right side it fitted perfectly as the hinge is slightly different why i Know not but is different So i put the origional back on the left side and new one on right I think maybe if i ground a bit of the fitting it will go but im unsure which way to jump anyway thought ide let you know may help someone else Robert

you could see if it will reset the button is just above the your left foot in line with the brake pedal but ill bet battery as expired

Battery will have failed mine went last year sensors are 60 charged 30 to fit i kniow its a lot but you cant get round it

battery will have expired in one all all but have you had any tyres refitted as there is a procedure for changing them

Thanks David I Have looked on there site And the numbers on my strut match theres at £36 each so ill give it a try and report if all goes well Thanks again Robert

Hi Ive just found out that my Boot struts look like they are failing as its getting harder to open the boot but easier to close it i checked with lexus and they said 102 per strut i coughed surely not , not a strut but said yes thats correct Does any one know of a supplier that does these i have heard of SGS but they only do 1998 to 2005 Thanks in Anticipation

Hi I have GS300 gen 3 every car i have ever had with air con at the end of a journey there was all ways a pool of water under car perfectly normal My car as never shown this no water ever 1 is this a problem 2 does the condensate drip somewhere else 3 where is the outlet thanks guys IA

just as an aside to this it could just be that the air outside sensor is fubared and is not recording actual temp (but i doubt it )as if it is over 22 C it will make the recirc come on and cooll down interior when it drops below this the recirc reverts to fresh But here is the rub if the recirc flap lever is broke which many are due to pollen filter not replaced correctly then even tho the recirc light comes on it does not mean its in recirc mode the servo motor moves over to change mode but if its broke will not open so it stops there as it cant cool down interior see the post on this i explained it in detail yu will be suprised how many Is.s and GS,s are running round with this lever broke

Check that the Recirc/flap as not been broken see my post on this

just as an aside to this went out today and suddenly realised there was no rattle from pass side i did have a rattle here and couldnt figure out were it was coming from thought it was door then thought it was seat wife thought it was coming from sill, But as now gone this was after siliconing the seat belt it must av been something at back of pillar but as now completely gone good result

i should have said code it to veh not initalise thats a different procedure the TPS cpu needs to know the code of the sensor so its no good buying one and fitting it yourself it needs the Techstream to do it and its a Lexus bit of kit robert

i have just after reading this thread bought a can of crc silicone spray as my pass side belt was a bit lazy and as been caught in the door and put a scratch on the inside sill it took a couple of mins to apply and the result was instantaneous operates just like a new belt so did them all also the drivers front window on opening made a slight grab sound as it came down just as it cleared top i applied to runners and top rubber seal and voilla no grab i can certainly reccomend silicon thanks OP

I too looked at gs300 like busta with the TPMS light on the dealer said would be an easy fix so would knock 100 of for it but i said no and walked away. The dealer rang me back said if he gets it done would you consider buying so i said yes. He took it to Lexus at Stoke who replaced itcost 156 i had copy of invoice. 6 months later i had to change tyres my local tyre place said could change them no problem I was concerned at the thought of damage to the TPS so i was stood there all the time and he looked like he knew what he was doing the tyres were fitted all 4 for 125 corner 600 in total. Went out the next day Light came on told them but said must be coincidence as we did not damage it I didnt get anywhere with them so took it to sheffield who said rear offside damaged they fitted one 110 total But went onto say The procedure is to let air out of tyre Undo nut and push sensor into wheel Take of tyre or realese it so can get hand in to retrieve valve replace valve and reinflate tyre then initialise it to system He then said we could have done same tyres for same as i paid and garanteed no sensor damage wish ide took them up on it Robert

If you get the TPMS valve from Lexus its 110 fitted that includes Initialising it to the System The ones from USA are different dont waste your Money Also if yu take it to Lexus and they break it they will replace it There is a Procedure for taking the tyre off my Local Tyre Firm broke two but said they hadnt damaged them and would not accept responability It would have been court case so i took it on chin I wish ide have let lexus do all the tyres was not much dearer than Tyre Depot Lesson learnt Good Luck Thats at Sheffield anyway

I decided to purchase the Latest Sat Nav Disc 2013/2014 and lo and behold they have removed the restriction for inputting Destination whilst on the Move also They have lifted the Volume as well would have been nice to have it muted when She tells you which way to go but i guess thats Hardware

I would like to put brighter LEDs in the interior light in my 55 GS300 1 is this feasable 2 how do i get the unit out 3 What bulbs will i need TIA Robert

I had all four of ,mine exchanged at Lexus Sheffield fpr 300 They look brill and Powder coated Im sure other Dealerships are same

perfectly normal will go off after a few mins
