Just wondering if anyone else is experiencing the same problem as me with this site. Basically the Forum homepage and the GS forum homepage have not updated since Tuesday afternoon. However, if I open up any of the other forums they are up to date. For example the forum homepage states the most recent post as being “does the IS300h AWD exist” showing there are two replies, the second being on Tuesday morning, but when I open it there are more replies with the last being from yesterday. Similarly when I open the GS forum it shows the latest topics as being “high mileage LS600h” stating it was started 11 hours ago, when in fact it was started on Monday evening. Also the most recent post in the GS forum shows as being “Buying a GS250 – looking for tips please” and states the last reply was 1 hour ago. This has been telling me this since Tuesday. Another problem I am encountering as well is when I try to sign in it tells me there is an error (code 2S119/1) but when I try for a second time I logon with no problem. Like I say I go into the other forums pages and they are fine so can someone tell me what is wrong please?

I believe the only choice for this would be fit 235/45/18 (same size as S4 GS 450h on 8Jx18" wheels) to keep any accuracy to your speedometer, although it will still show you going faster than you are as the overall diameter will have increased compared to the standard set up. A 225/45/18 tyre size is virtually the same overall diameter against 245/40/18 but I'm not sure they would wide enough to fit an 8J rim (happy to be told different). If you go for the 7.5Jx17" wheels with 225/50/17 tyres the overall diameter is also virtually the same as you would expect. I would also suggest that if you choose to alter the size of tyre on your 18" wheels you might fall foul of your insurance company as anything other than 245/40/18 is not a standard size for the S3 GS 450h. If you fitted the 17" wheels with 225/50/17 tyres this would not be an issue as these are a standard size that were fitted to some models.

The following is from an American company but the product details do state the OE part number:- https://www.hubcaphaven.com/p/6709/aly74209-lexus-gs350-gs460-wheel-hyper-silver-4261a30010.html I know they are listed on this site as being for the GS 350 and 460 but they were the ones fitted to the UK spec 450h.

Ah yes sorry John. The wheels fitted from 2010 are 7 spoke not 10. Are these like yours?

The S3 GS 300 SE also had 17" wheels fitted as standard and the attached ebay listing shows you what they look like and I believe these are the same as were fitted to the 450h SE from 2010:- https://www.ebay.co.uk/itm/Lexus-GS-IS-17-Alloy-Wheel-With-Nexen-225-50R17-5-5mm-Tyre/253882101459?hash=item3b1c8d6ed3:g:e08AAOSwRdta6dGp:rk:35:pf:0&LH_ItemCondition=4

The 2010 facelift S3 GS 450h had 17" wheels fitted as standard shod with 225/50/17 tyres in SE trim spec. The 18" wheels were standard fit on the SE-L but were an option for the SE so you should be able to fit 17" to your car. You will not be able to put 16" wheels on as they will not clear the front brake calipers. I believe the member you are referring to is John aka @royoftherovers

Your model like mine John had it fitted as standard but it became an optional extra on the top SE-L spec following the facelift of the S3 GS in 2008. It remained as an optional extra on the Premier spec when the S4 GS was introduced, only being fitted as standard again with the mid cycle facelift as @rayaans says above.

Yes I have seen that one and it is exactly what I would be looking for but unfortunately not at this moment in time 😞.

Lovely looking car Shahpor. That's the exact model and colour I'll be looking for. Interesting to note you mention the lamentation of the salesman that there will be no 450h version of the ES.

I think you've got that the wrong way round John. Pressing the button so that it stands proud (or out) disables the button from the drop down tray and the button on the keyfob meaning the boot can only be opened from the outside manually using the key in the keyfob. It's on page 30 of the owners manual headed 'Luggage security system'. If the button is in the recessed (in) position the boot can be opened by all three methods.

Might be a daft question but have you checked the bulbs haven't blown? If the boot opens via the remote and the interior button the switch in the glove box will already be set to ON as in the OFF position it disables those two functions. As the boot can be opened by these two functions but not manually I can only assume there must be something wrong with this mechanism. With regards to the camera, sorry, I haven't a clue!

My GS has two rear fog lights and two reversing lights, both either side of the number plate.

As you have a Luxury model you have a gen 4 GS. Trim levels for gen 3 GS are base, SE, Sport and SE-L. Trim levels for gen 4 are Luxury, F-Sport and Premier.

No mine haven't failed but I have been thinking about this for a while as the matter of hybrid battery failure always gets mentioned when any prospective owner asks on this forum what to look out for on the series 3 GS450h. It is also stated that there is a higher failure rate for this model compared to other Toyota/Lexus models from the same era. Now, I am just throwing this out there to see if anyone more knowledgeable can add to or confirm or tell me I am completely wrong about this, but I'm wondering if it isn't actually the owner of the car who has inadvertently been responsible for the hybrid battery failure in the first place. I am only thinking this as the air intake vent to cool the hybrid battery on a S3 GS is situated on the rear parcel shelf or package tray and a warning notice on page 11 of the owners manual states “Do not put foreign objects over the air vent. The hybrid battery (traction battery) may overheat and be damaged.” The GS is a saloon and I have seen plenty of other makes of saloon cars with stuff on the rear parcel shelf so how many GS 450h owners may have put a coat, jacket, pet (dog!), cushions, road atlas or anything on the rear shelf without realising this and have obstructed the vent? So my question is basically could any resulting damage from overheating ultimately lead to hybrid battery failure? The other hybrid models that the GS is compared to are either hatchbacks (CT/Prius) or a SUV (RX) and they don't have a fixed rear parcel shelf so obviously the air intake vent to cool the hybrid batteries is in a different place on those cars. I don't know where the vent(s) is/are on those cars but is it a place more difficult to obstruct? As I said these are just my thoughts and I may be completely wrong but what do other forum members think?

But will they be up to the job? Genuine question as I don't know. I know the 450h shares the same front suspension as the 430/460, which is more 'beefed up' than the 300, so if the 300 uses different shocks it must be for a reason. That's what I paid recently for one a Lexus Carlisle (excluding fitting).

Those are the correct alloys for the 2010 facelift version of the 450h SE-L, the SE getting 7 spoke 17" alloys with these 18" being an optional extra (although prior to this all trim versions of the 450h were fitted with the previous design 18" alloys) but they would have been silver. FYI the info below indicates the level of equipment you can expect to find on this model but they relate to the 2008 facelift and a couple of things did change for the 2010 model As you can see there were four trim levels available but for the 2010 facelift only SE and SE-L were retained. The '06 to '08 cars have the most standard equipment (the SE-L having ACC/PCS and sunroof as standard) but these became options from 2008. However to 2010 cars did get, amongst other things, DAB radio and the deletion of the cassette tape, a redesigned front grille and alloy wheels and I think also improved safety features. Enjoy your new car, I'm sure you won't be disappointed.

The following show the standard equipment for the four trim levels of 2008 facelift models but are roughly similar to the 2005-07 original cars, indeed these original ones are probably better spec'd as on the facelift cars standard equipment was either deleted or became an optional extra. Those 'options' quoted in the Parkers guide are incorrect as all those features were standard on the SE-L (I believe the sunroof became an option from 2008 onwards). In fact cruise control and central locking are standard across the range and if it has a Mark Levison audio system it should have a DVD player. A 430, shown here in the newer 460 spec, wasn't sold with different trim levels so everything was standard. The only options options on a 430 were, I believe, metallic paint and a part wooden steering wheel and gear knob.

Denso are the OEM wipers and I always fit them to mine as I have also found them to be much better than other brands. I get them from www.carparts4less.co.uk . A look at their site shows a set for a Mk4 GS for approx £26.00 with free delivery.

I could be totally wrong but having seen what appear to be fixed aerials on bumpers of Japanese imports I would guess (and it is a guess) that they are an indicator to the driver as to where that corner of the car is when manoeuvring as they are always on the front left. There is a picture of it on the seller's website showing it fully extended on this car so obviously being a Lexus it is retractable! Possibly think of it a predating parking sensors. I don't know if you have been onto the seller's website Phil, but on it there is a tab headed 'Japanese Car Insurers' and lists a number of insurers. Also there are further pictures of the car on the website, one of which shows the buttons on the dash to the left of the screen are in Japanese as are the graphics on the screen when the reversing camera is activated.

Are you looking at page 374 and 375 of the manual? The images show a lhd interior. P374 is showing the tyre pressure reset button. On rhd models it is more to the right of the steering column. P375 shows the position of the switch for the TPMS on a lhd model. It is not in the glove box. On rhd models it is on the passenger side, underneath the dash and next to the bulb that illuminates the footwell.

There is a switch on my car, just seen it whilst looking for the fuse box. The manual makes it appear as if it is in the glove box but it isn't. It is beneath the glove box and is next to the bulb that illuminates the passenger footwell.

You are correct. It is a 4.3 litre V8 and not just in the USA.

I don't agree it is "better" spec'd when OP states his current car has live traffic satnav (2017 maps), in car WiFi, lane departure and auto brake. As far as I am aware these weren't even options on The Mk3 GS 450h. As Phil says above they are both high spec but different. Also need to be aware when looking about the change in standard equipment I mentioned above between the spec on the original launch cars and the 2008 facelift models.

The GS 450h had 4 trim levels. Base, SE, SE-L and Sport, SE-L being the top spec. The spec sheets below apply to the 2008 facelift model. The equipment levels on each trim level were downgraded slightly compared to the 2006 and 2007 model year cars but they still remain well equipped. A few examples are the rear lip spoiler and cooled (ventilated) seats feature are standard fitment on the original SE spec but were deleted from the facelift model, and on SE-L spec the PCS/ACC and electric sunroof were fitted as standard on the '06 and '07 cars but became an optional extra on the facelift model. You can tell a facelift model as the side indicators were moved from the wings and into the side mirrors. There are a few recent threads on this forum about what to look for when buying a 450h so have a read through them and good luck with your search.
