how much you get on cruise control at 60mph motorway without towing?

it could be better I think I get 40MPG highway but of course just car itself 60mph cruise what was speed for you?

ok thanks for answers try to change them soon, tyre pressure is OK I checked many times.

Just noticed that if I accelerate RX400H wants to pull right... otherwise seems it keep road normally If I hold my steering wheel normally I hardly can notice it but I if I release it is noticeable, so this pull is minimal and even not noticeable if I keep steering wheel normally with both hands... Anyway it indicates some problem which can become maybe even bigger in future, what would be possible causes? Front tires are different brands and thread in right seems little bit less maybe 1-2mm I think it could be possible cause and change them anyway soon, but what else could be wrong in worst case scenario?

here are my data on RX400h motorway 60mph with some small stops in city was getting 40MPH on other trip 42MPG on other trip with lot of hill driving very slow ~1.5H in hills total distance 125miles then was 35MPG one more trip was driving country roads pulse driving average 40mph then got even 50MPG also with some very slow hill driving. So far with 400H I get even better as manufacturer claimed results. Obviously best results you can get with pulse driving with average speed 40MPH and from time to time use EV mode with cruise control at 40MPH that's why in city I can get same or better MPG as on highway

ok so now I bought 2005 lexus rx 400H overall first impressions are good I like car much better as GS450H 1. There is no noises and rattles from dash 2. Much more comfortable 3. Braking is smooth and did not noticed any shifts from regenerative braking to normal. 4. I can't feel much how engine switching on sometimes feel little bit but it's same like with GS 5. Fuel economy and how hybrid works... It's much better as GS450H first maybe because RX has 2 generators when charging battery, so battery seems charging faster, it's much more easy to drive electric mode only with GS I had to be extremely careful with accelerator pedal to get it in electric mode, when battery get to 2 purple bars GS engine started to work all time except when release accelerator in RX that's not a case it can drive only electric also with 2 purple bars, eventually of course engine kicks in if driving too much electric, so what it translates to real numbers: in city with warmed up engine ~5mile distance I got 40mpg in the middle was even little bit traffic jam... so average city driving of course I tried my max to get this number pulse driving then when possible drive only electric mode get to 30mph then release accelerator then lightly push to drive only electric etc. Then the best fuel economy was 8 mile distance with 56MPG also have to note that battery was charged to 6bars from highway driving and when stopped it was 3 bars. With GS it would be almost impossible to get these numbers.... When push hard it goes hard as well so performance is also good...

yes car stayed some time and he told something that battery gone flat, BTW I looked other lexus 2 of them and these also had some error codes similar with VSC and airbags, although all worked fine.

car is looked after serviced all time at mine dealer and last time just 2000 miles ago it did not throw codes on test drive these were before I cleared them and then did test drive again and then all was clear so codes did not reappeared. It was 65000km since last time DTCS were cleared so maybe it's just sometimes low battery etc and these codes appeared

Hi, I consider to buy RX400h but there were some error codes, 1 abs vsc c1241 means low or high supply voltage 2. tilt @ telescopic b2602 key unlock warning switch b2620 ecu power source circuit 3 gateway b1281 airbag ecu communication stop first 2 were current 3 historical I cleared codes went for some small test drive and then all was clear. Just thinking if that is something serious or not??? On dash no error messages and everything seems to work fine.

ok it should be so, in GS if it was staying then also I could feel little bit how engine start but in driving almost no then it's similar like RX.

15K miles for 2006 seems suspicious it could be also that clock was turned back before every service and MOT or something happened to car and it stayed long time and that also not good. So 2009 GS is good option with 77K miles what is price???

Great so you don't feel how engine turns on when accelerating or turn off when braking? That's how it was with GS, how is dashboard is it quit and solid?

I read some user reviews and some says that they can feel hard when engine stop working or switch on when driving... also braking not very smooth there is some shift from regenerative braking to disc braking. Is that true? How it's comparing to GS450h 2006? With GS450H everything was very smooth braking as well I could only see in screen that engine turning on or off but almost could not feel it. Only when standing then if engine started to run I could feel little bit how it started. How is comfort how it feels over bumps GS450H was too hard... Is there some problems with plastic dash does it make some stupid noises or is it quit? GS450H made some weird noises all times from dash :( especially when cold 2 things drive me crazy some stupid sounds from dash and hard driving that's why i sold GS450H What are typical problems with RX400H? I read some coolant leaks what happens in that case car stops completely or it runs some time then?

some times it was not increasing RPM at all sometimes increased RPM slightly, it's possible also override hybrid system just have to push accelerator when in P and engine start if it was in hybrid electric mode at that time.

found interesting document about this error P0A92 it is about prius wondering if same would apply for GS450H??? seems BATTERY CURRENT SENSOR could be bad... http://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/repair%20manual/04pruisr/05/21bpm/0a92606.pdf#page=1&zoom=auto
