I have an RX300 2000 and I get about 19 - 20 MPG driving in the city, but only get up to 21 - 22 on the highway, sometimes lower depending on my speed........... I used to get 23 - 25 MPG, but here in Fl 10-% ethanol is mandated, there are only 2 stations left that sell the "old" 100% gas stuff - they say it increases your mileage by 3 - 5 miles per gallon - the ethenal is also really bad for our engines etc - but this just means they can sell us cars more often - I think it is a big scam with the ethenol - costs more to make, doesn't seem to be saving us anything and makes you fill up sooner............so where is the savings?? I also was running leaner when my knock sensor needed to be replaced and was enjoying 25 - 26 MPG!!! I even asked if there was an ajustment to run leaner, they said no. I think my drop in gas mileage is EXACTLY due to ethenol.

I had my oil changed yesterday - at an independent Foreign Auto Clinic in Melbourne, Fl - I asked for Synthetic - don't think I have used it before - it was about 43.00 out of a 91.00 bill. Had to have a new battery cable clip put on - battery acid keeps leaking out - so I bought a battery at Auto Zone instead of another Lexus one. I am going to put up a post regarding battery acid leaks - so far I have not seen this topic, but as this is my 3rd battery plus original on a 2000 and all the same problem - leaking acid.........

JUST today my RX300 did your window thing.............started to put it up and it comes up part way and then goes down, did it again and same things up and then down - finally after several more attempts I just put it all the way down, breathed a big sigh of relief as it then went back up - like you I am afraid sometimes of putting it down. It has done this a few times before - on both sides - but then goes months and months without doing it - What is the Pinch thing - and would it be necessary if it only happens every now and then??

Did you happen to notice if your RPM's were way up??? That happened to me when heading out on a trip, I have a 2000 RX300 and about a half hour into the trip I noticed the "Pitch" of the engine was wrong, slowed down and was better, sounded like the car was "racing" - well it wasn't going into overdrive - it was the oxygen sensor. This is very expensive to repair - and I feel my Melbourne Lexus dealer really ripped me off - worse the 2nd time - when I had an oxygen AND a knock sensor done - I no longer will go there for anything, especially will not buy my 4th lexus from them!! They charged me $3500.00 for the two sensors - installing my "Free" ya right tires and some misc. items.........I was shocked at the bill. I usually drive just the 12 miles round trip to and from my office, in town driving, so I believe this problem had been happening off and on - but of course, on a long trip it did not go back and remained with high RPM's the whole way - very long slow trip home. Hope this helps,
