  1. It's more like a jet plane or a power boat under hard acceleration. The engine revs hard and the plane or boat (or e-cvt car) builds up speed until the power can be cut back. I know what people mean about the lack of gearchanges but I suspect it's just because we've had 100 years of having to have conventional gearboxes on cars. People get used to the jolt as you change gear and come to expect it as part of the driving experience. On the other hand, you don't get passengers on planes saying to their friends, "When's the pilot going to change gear?" I think we just develop certain expectations in certain circumstances and instinctively are wary of things that don't seem "normal". So much so that Lexus felt they had to install pretend sound effects to make it seem that the car was changing gear - but without the conventional jolting between gears. From what i've read, most people pretty quickly turn off the sound effects when they get used to the silence from the car most of the time.

  2. Confirmation, 2 Step Unlocking. All doors should unlock if you press 'unlock' button on keyfob Twice. So global unlocking ( single push) is available if you have Techstream in the Customizable or Personalisation settings, or if you still frequent the Dealers they may do it foc ( Ha!) next visit. paul m.

  4. Hi all. I am the owner of a RX 200t in Malaysia. 2017 model. From the moment I drove out of the showroom with my new car, I noticed an unusual behaviour of the engine. Whenever the vehicle is in the speed range of 80- 100 KPH, the engine struggles. This is evidenced by a vibration feeding back through the accelerator pedal and some through the steering wheel. The best way to describe this is to take the example of the old manual gearshift cars. If you were in fifth gear and you came to a slope, you would have to shift to a lower gear. If you didn’t, and after the momentum of the vehicle ran out, the engine will start an unpleasant growling and rumbling as the existing power gear relationship was not adequate and would not be able to sustain the power demand on the engine. This is exactly what I am trying to describe. The engine does seem to have all the power the car needs throughout its operational range. But it seems that the manufacturer’s setting of the gears for this power regime seems to be the problem. And this problem is only evident in the 80-100 KPH regime. Outside of this, the engine performs well. At my first service of 1000 KM, I highlighted this problem to the dealer’s service manager. He test drove the vehicle with another senior mechanic on board. I demonstrated the problem to them. They acknowledged that there was a problem. Told me exactly what the salesman had offered as advice: Every time you experience this, just press on the accelerator to accelerate and that will change the gear !!!! I reminded him that this was my 6th automatic car. I had never had to do anything so stupid in any of my previous cars although they cost less than half of what I had paid for this !!! A few days later, I was informed by the service staff that all the other models available at that time were also tested out of curiosity, and, shock………they all demonstrated the same problem characteristic !!!!! Then I was told to email the matter to the manager for further action. 2 years have gone by, and until today, no action or any kind of interest has been shown by the dealer to solve this problem or to escalate it to a higher level for attention. I just completed my 40,000 KM service. Again the same old excuses (doesn't matter if you go straight into the back of the vehicle in front of you !!) and more empty promises to do something about it. But until today, no news of any action. Please check your vehicles to see if you have this problem. Look for the rumbling of the engine between 80-100 KPH. If you are in steady cruise, apply very gentle pressure on the accelerator, and you may feel it. Please let me know on this group if you experience the same engine anomaly. Thank you.

  5. If you are looking at spending that amount of money, get on ebay right now and buy Pete's supercharged ISF and you will have the best car that this amount of money can buy. That is all. 😎

  6. It does sound like that. The transmission should be correctly mapped to the engine so it does change down correctly rather than let the engine struggle. Seems that it could be a simple fix in software if enough owners complained. Unfortunately the number of 200T vehicles sold in the UK was very low. The RX200t sold less than 100 before it was withdrawn.

  7. The best performance is obtained by having the transmission in auto mode and letting the CVT keep the engine at a constant rpm at the peak power - which is 6,000 rpm. The torque curve is flat between 4,200 and 5,400 rpm so try and keep to at least above 4,200 if in manual mode.

  8. I'm with BatchelorDays. Cam or crank position sensor is the usual suspect, but confirm by reading the codes from the engine management system. An altwrnative bet could be not reading the immobiliser chip in the key. Reading codes from the OBD2 port will point you in the right direction.

  9. I disagree completely. Having driven/been driven in SUV's ranging from Audi and BMW to Volvo, I can safely say that my RX 400h is noticeably quieter than any of them, by a good margin. And the RX 450h is even quieter. The only time I even hear the engine when driving is when I accelerate quite heavily. Out of curiosity, what tyres are you running, and at what pressure? Because that seems more likely to be the problem here... And I literally live on a mountain on the forest by a dirt road, so I drive on my fair share of sh**ty surfaces 😉

  10. On an MB you wouldn't think twice and change the Crankshaft Position Sensor (CPS). But you don't see it mentioned as an issue with the RX. You could check the connector on it. I don't know it's exact location in the RX and I'm not near my car these days. Flooring the throttle doesn't do anything since the starting mixture is controlled directly by the ECU.

  11. Hi. My thought is that the 2.0 litre is underpowered and needs higher revs to keep going. In the UK we mainly have the Hybrids which are more powerful. Sent from my iPad using Tapatalk

  12. Nothing different reliability wise between all the F's. Servicing is mostly the same cost too. RC-F might be a touch more but nothing significant. I think the later ISFs are holding their value slightly better than the equivalent RC-F due to their practicality, and being the very last always holds a little premium. IS-F is easier to live with if you have children for example. Interesting to see what other people's opinion on this is. I'd go for a GS-F if you need the extra space or want the presence of a larger car. If not, get an RC-F if in budget and suitable for your needs, or an earlier IS-F.

  13. Yes it has - just the same as the RC - can have it's uses or just for a bit of fun. Mind you, the acceleration time is actually faster when left to it's own devices...!!!

  15. I too would trust Lexus over Admiral. I was insured for a year with Admiral on a multi-car policy, and I found them unhelpful at the best of times., and certainly not customer-focused.

  17. Thanks again to everyone for the help. The local garage charge me £75+VAT to change both upstream sensors (that I supplied from Sparkplugs.co.uk £176.54 inc Socket) which I think is very reasonable. I haven't had chance to speak to the mechanic yet to find out how easy or difficult he found it. Only one sensor was bad so if anyone is on a budget and wants to offer me a few beer tokens for the working s/h one feel free. It will be nice to have my Lexus back after a couple of days of doing my 80 mile round trip commute in the wife's 12 year old Jazz.

  18. TBH for a Lexus dealer that is amazing cheap if that is for a new master key and programming to the car ( check this is for both). The problem is that the master key is always needed to clone either another master or slave key so even an auto locksmith would struggle. Too late now but a missing remote key would have been a good bargaining chip when you bought the car and probably would have paid for one with the discount. The procedure in the link below explains how to clone the key but again you need the master not the slave key. https://www.key-programmer.com/2016/07/22/steps-to-program-key-for-lexus-gs300-400-430-98-05/

  19. Having had my NX for almost a year, this afternoon I've completed my first properly long trip of 200 mainly motorway miles (usually I fly or take the train for business and if driving we get hire cars, but this is a personal trip). Ignoring the performance question, as it is quite fast enough for the way I drive, today's trip has shown me just how quiet and comfortable the NX is - getting out I felt like I'd done 20 miles rather than 200! With cruise control on and Spotify streaming to the car audio it was a very relaxing way to travel, admittedly on very empty motorways. Even the performance, when needed, seems fine to me - it's faster than my previous Honda CR-V anyway! I'm very satisfied.

  21. My RX400h is a 2008 model and has clocked 130,000 miles. It has had both the motor battery and main computer replaced at separate times by Lexus as it was a recall model. It remains one of the best drives I have ever had and with regular servicing has given me no other problems. Nevertheless it is not as quiet a ride as that of luxury European SUVs. Whilst engine noise is on a par, tyre noise can be a problem. Choose your tyres well. I have found the original factory fitted Michelin ones to be the best.

  22. Mine has done over 100k, and quite frankly, that distance shouldn't worry you with any proper brand. Most decent cars are simply made to run way longer than that.

  23. Yes it does, or it can be bought as a stand-alone check for about £60 (about €68) and as long as everything is alright, it gives you one year of cover.

  24. Hi MadJam My Ioniq is a hybrid self charging, a 2019 model, drove this Saturday 112miles around Cheddar, achieved 73.3 mpg with 4 people in the car. Will see what I get from my Lexus when it comes back from the garage, next week at the earliest.

  25. Main thing to check is that it has a valid hybrid health check certificate. If so Lexus warranty the batteries now for 15 years. I understand that batteries generally aren't an issue. The inverter apparently is the big ticket item that can cause issues. Plenty of good advice from owners available on this forum. All hybrid Lexus are extremely quiet.

  28. Well, I emailed them and the guy was very helpful and said it can be done. But not many people do it. And that gearbox tuning can’t be done on this car. But engine remapping can. For the money it might not be worth the 20+ bhp gain. But it can be done

  29. Bunch of nonsense in their website - The gearbox ECU on IS250 is self-learning, if you want remap then just disconnect the battery for 15 min and let it reset. Then drive the way you want and it will set the gearbox accordingly. I have driven mine like stolen for few days and then realised gear changes became very sharp and unsubtle, then had few nice weekend drives just cruising around - got back to buttery smooth. As for the engine - again nonsense. Where they getting that "extra peak power and torque"? It is atmospheric engine, more air and more fuel can make more power, where does extra air comes from? Throttle response I can understand - there is little button in IS250 which says "sport/snow" - it does exactly the same thing - sharpens throttle response. In other hand it is not like throttle response is "laggy" in IS250 - that is the strength of NA v6. And just to prove it is non-sense here is comparison between IS250 and Aston Martin Rapide text In short they just have generic text with "insert" vehicle info of all vehicles 😄

  30. NA petrol engines are not worth remapping, it is not that important whenever it is petrol or diesel, but more important is that diesels nowadays are by default Turbocharged. NA engine is by default limited to the amount of air it can get, and as such the amount of fuel they can burn at optimal air/fuel ratio. You have to significantly alter the NA engine to get gains in power, from minor upgrades like the less restrictive air filter or exhaust, to highly expensive ones like lightened pistons, shaved heads etc. On turbo engine, it is just a matter of pumping more air from turbo and adjusting fuel/air mix in ECU. Obviously, even trubo engines has limits before you need bigger turbo or injectors or the rest of the parts to sustain the additional power, but even the most basic turbo engines can gain like +50hp by simply re-adjusting ECU. NA engines needs expensive physical mods + still needs to re-adjust ECU. To summarise remaining NA engines are lose/lose scenario - big expenses little gain, theoretically doable, but practically pointless. As for those doing across the pond - they as well turbo/superchagring IS250 (but more often IS350) and then remapping, I really doubt anyone does it on NA engines. Obviously, micro-modes are possible to remap throttle, but that is not what I regard as remap.I guess you referring specifically to the engine remap for the purpose of gaining power, not cosmetics of how it is delivered.
