Went on a very long - 4,000 mile - journey for graduation two weeks ago. Drove from Texas to the east coast and back again. In evey non-hybrid car I've had, the mpg rate would always increase with highway driving. No so with the RX 400h (2007). It started out a with a wonderful 27.4 mpg… and kept dropping by tenths as we went along. Now, it has rested at 26.9. I can notice this mpg decrease in my everyday driving. What happened? Can it be improved? I changed the oil and cleaned out the air filter immediately after my return. Does it need a tune up? We've got 95,000 miles on it now. Thanks for your advice.

Hi: New to the forum and hoping to buy an RX400h. To be honest, I wasn't even considering a Lexus because I figured it was beyond our budget and didn't get the mpg that we need. But then I came across some things the other night and was quite surprised by what I found.
The units that I've looked at are in the 2006-2008 range and normally at 100k. From what I've been able to read here, it seems that the battery system is probably of greatest concern. Is there a way to test the battery before purchasing -- or is this a crapshoot? Also, what other things would be important to look at?
Per our needs: I live in a small rural community. Much of my driving includes trips of 20 miles or less one way, though there are plenty of long rides, as well.. I drive about 35k/year. I need to get at least 25 mpg on hwy. Am I wrong to think that the RX400h would be a good fit?
Hi i'm new to the forum, I searched already if this subject exists, didn't see anything close to my situation. I have a 1994 Lexus LS400. I bought the car from a sketchy guy, but the car was clean and i believed 178k miles sounded right. after owning the car a month I Car Fax'd it finding out that as of August 2007 it had 234k miles, and May 2010 it was found to have 190k miles. the next owner drove it to 246k miles as of August 2012. within the same owner, during another service, it was documented at 208k miles. He then sold it to me at 178k miles. I know he rolled it back and tampered with it, because the capacitors went out (Normal issue) and i had a professional change them. This car has OBD1 so I don't completely know how to roll it forward to be honest with the mileage, or even if its legal. any suggestions, thanks!
Okay so... I own a Lexus RX400h and I have noticed that when my A/C is on my car is not as quiet as it used to be. For some reason It was vibrating ONLY when the A/C is on and also made a rattling sound but kind of low. When I turn off the A/C the car goes to normal. My father checked under the hood and he thinks that it is the fan for the air conditioner. I am taking it to the dealer anyway to get it looked at but I would like to know if somebody here already did this service and how much it was. I already did a super complete service a year ago and they replaced a LOT of things. This service was almost $3,000. If I have to spend much more I swear I'll sell this car. -_-
I recently replaced my rear brake pads on my 2006 Lexus RX400h, and when I started the car after the replacement, there was a "Check VSC System" that appeared, with a red "BRAKE" logo, an orange "ABS" logo, and other logos came on too. I'm confused because I did a neat job on the brake pad change, and I'm wondering what's wrong with it. The owners manual says to contact your Lexus dealer, and I'm trying to find out if I can fix this problem myself before I take it to the dealer. The car is alright to drive right now, but I want to also know if it's okay to keep driving with the VCS and logo errors on.
