Our 2005 RX330 was 18/19 mpg. Our 2006 RH400h is 25/26 mpg. The 400 is considerably faster than the 330. It is also faster than the 350 (test drive and had loaner), but the 400h is heavier and you can feel it in the turns. You will also notice faster tire wear with the 400h due to higher weight and same size tires.

Having said that, with the tax credit and at 15,000 miles per year, I'll get my money's worth say in .... 4 years or so?

The RX350 and RX330 were great in 1st gear, but at second gear, it just dies and bogs down. 2nd gear is just too tall IMO. What the 350 needed was a close ratio 6 speed automatic or that new 8speed... or the IS350's direct injection engine.

We've only had our new 400h for a short time. After about 600 miles we're only getting about 20mpg. It is winter here in Wisconsin and I hear the mileage is worse in the winter. I hope the mileage gets better. I am using Premium gas, and have checked tire pressure. Even though the mileage isn't what I had hoped to get, it is better than the other SUV's I looked at buying.

My only gripe with the car so far is the way the antenna for the XM radio is installed.

Yes, the mileage gets worse in winter because everytime you start up the car the engine will start immediately to generate heat for the cabin.

I found this on the Lexus website. Interesting to say the least. http://www.lexus.com/hybriddrive/fuel_tips.html Look at the sub links as well. This is good information.

They also explain what EPA fantasy...er...lab tests are about in their delusions...er..."estimates."

BTW, my 400h is still getting better gas mileage than when I first got it. I would also guess no A/C this winter is helping.

Interesting. Now that you mention it, I don't remember seeing any ugly yellow tags in RXs. It is especially interesting since the EPA estimates are bogus for the real world and are supposed to change in the next year or so.

2006 AWD. Purchased the car as a lease return from the Lexus dealer about six years ago with 60,000 miles on the clock. Currently at 200,000 miles. MPG varies. For a tank, usually runs between 24.5 and 26.5 mpg. I'm an 'easy' driver, (i.e., no 'jackrabbit starts, rarely above the max posted speed limit).

Wow, you revived a really old thread - but don't go away - I'm hoping to see 200K on my '13 RXh (have 38K Miles in 22 months); and I'm interested in reading any observations/issues/problems/suggestions you have with respect to how you've managed 200K on your car. What are your plans?

Thank you, in advance.

Based on the thread title, seems like a thread that shouldn't die. Just wanted to pass on my "real world mileage".

200,000 miles? No real secret. I usually keep my cars for between 200K and 300K. On this particular RX, I just faithfully changed the oil every 5k miles and fixed stuff when required, (which was not very often). The car came with the certified 100,000 mile warranty, and I did need it for replacing the Mark Levinson audio system. Did the major services as mileage required. And as mentioned, I drove the car fairly gently.

If it wasn't for the inverter coolant leak, I'd keep it and use it on a daily basis. Other than that, there really wasn't anything 'wrong' with the car.

Ended up selling it to my best friend who really, really wanted it for $2,500. She knows the car well and has a '06 Prius, so knows hybrid technology. I made sure she knows exactly what is involved with the inverter leak and we're going to keep an eye on it for now. If the leak doesn't get too bad, we'll just add coolant from time to time. Only thing we'll need to address in the next year is replacing the timing belt.

For me, I would have jumped in a moment for another RX hybrid. This one sat at the dealership for a long, long time. I was able to get it for $25K or $26K, (can't remember which). All the other RX hybrids they had were in the $30k-$35k range. The cost of Lexus repairs have sort of scared me off of getting another one, and really didn't want to pay $35K-$40K for another used one. I retire next year and my income will be a lot less. I need a car that is fairly reliable, (as the Lexus are), but also not quite so expensive to fix. I purchased a new Toyota RAV4 Limited AWD. Nice car, but it sure isn't a Lexus.

Thank you. I'm retired, too; and want the same reliability as you do. I'd have been real tempted to contact the manufacturer of Bar's Leaks to see whether it was compatible with whaterver the collant is in the inverter - and tried that (after ensuring that the stop-leak goop wasn't metallic). As a mechanic back in the late sixties and early seventies, I saw near miracles using those little "rabbit turds in brown goo".

As I'm planning on getting ten to twendy years out of my RXh, I'm also concerned over potentially horrendous repair bills afforded by the super-pricy exhaust heater/cooler, batteries, gearboxes, and of course, electronics.

At my current rate of usage, I'll be out of warranty in under a year - and had considered an extended warranty -- only I have had bad luck with two prior extended warranties (Transmission died just out of warranty on one German car brand; and the other German car brand's repairs were not on the "covered" list); however, I have not yet killed the idea entirely.

Congratulations and best wishes on your new car; and thanks for the post.

the coolant in the inverter is same as what is in the engine coolant (type Toyota Pink pre-mix) however what it passages thru is the unknown. I know the pump is electric for moving the fluid.

22 on average over 3.5 years but I have a lead foot. I get a bit less the times we've had a 350 loaner.

I know the OP is ancient but the 400h is worth it to me because it's faster, smoother and quieter. The slight gain in MPG is just gravy.

Almost of 4 years for me of enjoying my ride and i believe there is no better MPG luxury SUV in US that can compete with RXh. In 4 years I average 27MPG in mixed driving

We just bought a used 07 RX400h. Driving it back from Texas it averaged 24-25. First tank here in Atlanta was 27. Second so far looks to be 25-26
