I did search before i posted, losts of posts of T1-R but no mention of any Toyo 'R32', which is why I'm asking if anyone else had them fitted on a IS SE....well....anyone else??

Well I came across this too: http://www.toyo.co.uk/uploads/car%20tyre%20brochure%2006.pdf If you look at page 10, top right hand corner they are mentioned there as OEM on the IS220d/250 SE. Anyone else get the R32?

I got 17" Toyo Proxes R32's for my IS250SE The ride on my car has been quite rough and choppy, and the Lexus engineer I spoke to about this said he'd never seen an IS come with that make of tyre, neither had his colleague. He said he'd seen them come with either Bridgestone or Dunlops. So what did you guys get? And what do you know/think of this particular Toyo? Cheers Neil

I had the same problem as you for a couple of days, and so far the problem hasnt re-appeared. Starting from the inteference explanation I did try a couple of things. I have two wireless routers in my house and I switched one off them off and changed the frequency of the other but I can't say for sure the problem went away immeadiately it just sort of fixed itself over the next few days if I recall correctly. So cant say for certain it had an effect. Then I came across page 8 -11 of the user manual - it lists all the get outs when it wont work, I have listed some of them here: http://www.lexusownersclub.co.uk/forum/ind...=36087&st=0 post 22

Does anyone know if the Mark Levinson audio system is available as an option on the GS300 SE? Ta Neil

dealer hasnt found anthing yet but i found this thread which seems to point to the bumpy ride being more subjective than anything. Some people have posted saying the suspension settles down after a few thousand miles, others have been helped by a lowering of the tyre pressure: http://www.clublexus.com/forums/archive/in...p/t-217330.html

Thanks for the suggestions guys. I have 17" wheels and I checked the tyre pressure as Rich said and set them to the values suggested by Jamboo. Spikes, I have the same doubt as you say in that I may just be noticing things I didn't before, however I can definitely feel more bumps and unevenness in the road than I did when I first drove the car to the point where it has become slightly uncomfortable to drive. Going get it checked out...

I may be imagining it but my month old IS250 suddenly seems to feel a lot more bumpier when driving on the motorway or even regular road, have the roads suddenly gotten a lot less smoother overnight. I swear I didnt have a drink last night. Seriously, is it possible for something to go wrong with the suspension or other mechanism overnight to make the ride a lot less smoother? :o

Quote from page 11 of the manual "The system may not operate properly in the following cases: - The electronic key is too close to the window or outside door handle, near the ground, or in a high place when the doors are locked or unlocked. - Gripping the door handle when wearing a glove may not unlock the door - If the wirless remote control is used to lock the doors when the electronic key is near the vehicle, there is a possibility that the door may not be unlocked by the entry function... " Also of note is the battery saving function on page 10. It seems like they found all these issues, which would commonly be labelled as bugs or defects by project managers and testers, and instead of fixing them have simply decided to list them as warnings in the user manual. Great. Just great. Wish I could get away with that at work.

Rich Bee You are right. Page 8 of the user manual. Bugger!!! What a get out. The project manager's I have worked with would find some of those caveats quite unacceptable and force us to design a more resilient system. lol there's more on pages 10-11, this is a right laugh!! i can see potential bugs everywhere!!

The example of brakes was to point out that just as you would complain about the brakes you should complain about the the remote locking not working too and not just bear it in silence just because it is not safety related as to me being able to lock and unlock my car is quite critical to its operation. People rightly complain to their dealer about squeaky wipers and rattles so making a fuss about this is acceptable in my opinion. You have to ask yourself if your patience or pragmatism would last if you happened to get locked in a car park that closes overnight or were you to get a parking ticket because you couldn't unlock your car in time. It will probably happen to someone in their Lexus and with Sod's law it will happen on their wedding day. The fact that it is intermittent makes it worse because you can't predict this fault that you are aware of and it can fail at any time or place. You just don't expect something like this out of a brand spanking new £25k car. I mean, aren't the other car systems based on radio waves too? From what I have gathered the keyless entry system has 7 aerials - 1 in each door, one in the boot, one to detect if the key is in the car itself, and one backup. Like Bob above, I am confused as to how it is actually possible for a signal to overpower the detection of the key by all 7 even when the key is actually touching a door? When the engine won't start unless your holding the key to the button? What is it that is so powerful in my cul-de-sac that then just disappears a few days later? A likelier explanation perhaps, would a signal from somewhere not drowning out the key fob entirely but actually confusing the software on the fob or in the car itself i.e. a software bug, which means its fixable. But all this is speculation, the only people who can really tell what's going on are Lexus/Denso, right? So you have to ask yourself, is it worth the effort to make a phone call (01737 367601) to let them know, and hopefully prevent possible scenarios outlined above?

Absolutely - and if we could "see" the amount of radio waves around us all of the time we would freak out!! It's likely to be a specific interaction of a number of radio waves in any one area which causes the problem. I could never get my Audi to lock or unlock at a particular Merc garage in Coventry. The garage told me it was "normal" in their car park for this to happen. Rich Bee, I'll rant and get indignant if I want :) It is people like me who complain that helps manufacturers fix their problems. I know. I work in software, and if our users didnt complain we wouldnt know of half the problems that arose if they didnt test our products in the real world and give us feedback. As an end user, I don't and shouldn't care about inteference, or who the real manufacturer of the equipment is or whatever excuse the car maker wants to throw our way to sidestep the problem and wash their hands off providing a fix, no matter how presitigious the brand. If I ever sold a system that occasionally failed to boot I wouldn't say to the buyer "oh its because the motor on the hard drive sometimes doesn't start because of static electricity, move your machine to the pantry where there is less of that" or something. Even though sadly some in my industry may have probably used that line, I dont expect your average computer user to have to know about whats inside the box, we accept responsibility for the whole and send someone round to fix it, which is what you would and should expect, especially with what is meant to be a luxury brand. The spectrum is already regulated and licenced to prevent major clashes. But not dealing with inteference is a failure of the implementation of the technology because it seems some of the 'cheaper' manufacturers like Ford and Peugeot can seem to build a system that works without locking you out of your car or not letting you lock it in the first place, which are quite serious and aggravating issues as you can imagine. Of the top of my head I would say a potential fix would be for the transponder or aerial to detect inteference at the frequency it was operating at and ask the key fob to automatically use another frequency or boost its output. Or ask Ford how they do it. I doubt you would be defending the problem quite so much if say the brakes on the car totally failed because of 'inteference' from rain water. And if you did then maybe manufacturers wouldn't be so compelled to invent technologies like ABS to help because they would think it did not bother you too much when you couldnt brake during bad weather. Sorry for the long and ranting post, don't get me wrong, I like my new Lexus, but it sets me off when they try to blame everything except their technology and are really patronising to you as well (e.g. "did you turn off the engine first before you tried to lock it? no I like to keep it running so the car is warm in the mornings darling."). Like there can never be anything wrong with the actual product. It is when we stop complaining and live with it that we say goodbye to improvements and progress and ultimately end up with below par unreliable, poor quality products and systems, much like the old British car industry that used to exist :P . Sorry, couldn't resist. So, moral of the story, keep complaining and give em your feedback. Otherwise they'll just surf the internet all day. Doh, back to work...

Magically the problem disappeared yesterday and I can now lock and unlock the car outside my house which was causing trouble before. But this morning the keyless entry didnt work the first time I pulled the door handle. There are a number of wireless hotspots in my area but as has been mentioned these operate in an entirely different frequency spectrum. And also no problems with either the Peugeot or Ford thats in the same driveway. I got a call from Lexus UK yesterday asking for feedback on my new purchase etc and I told them the problems and asked for it to be escalated, I suggest you contact the equivalent centre in Australia and let them know, hopefully with enough complaints this might make them prioritise a fix for this. I've not asked yet but maybe a dealer can reprogram the fob to work on another frequency?

thanks for your post ume. i just spoke to the lexus contact centre and they said its a problem that's not unheard of. I asked about the reprogramming and he said the local dealership would need the access codes from the regional manager which could take a few weeks!! will contact them monday as they are closed at present. neil

Sorry if this is a silly question, but wouldn't it have been easier to unlock the car manually using the key - rather than calling the RAC? Heh Wasnt aware and wasnt told of that by Lexus Coventry who recommended the RAC option, because if RAC had to tow it in then I would get a replacement vehicle if they had to keep it. :o Go figure. Also is it possible to start the car with the key if the fobs are not working?
