Replying to: timothyt (Jul 25, 2005 5:33 pm) I just completed a road trip that included crossing 4 mountain passes in excess of 7000 feet as well as fairly level stretches at sea level to 400 feet and I averaged 26.9 mpg. On a recent run from Portland to Seattle I got 28.5 mpg. I haven't had occasion to run mainly city driving, but am confident that the EPA highway mileage of 27 mpg is low for my 400h. Around my home I generally drive 90% highway and 10% city and have been consistently been avenging between 27-28.5 mpg using 87 octane fuel. I met another 400h owner who says he gets approximately 2 mpg better when he used 92 octane. I haven't tried that test yet. I generally run with the AC in the auto mode. There are two stages to the 400h breaks. When pressing hard on the brakes the graphic should not show any transfer of power either to or from the battery. I have previously owned two RX300s and this car is far superior in performance and mileage. |

Loads could be in many forms: extra weights, towing, electrical problems (unlikely with Lexus quality assurance). The car could have passed quality assurance in Japan but was messed around with, and damaged after shěpping to the dealership. The recommendation to take to another dealer is a good one because of many reasons. If they commented about the lurch as you said, I would not have much confidence about their ability to solve your problem (in fact, your comment leads me to think that they disown the problem). The system was engineered to operate smoothly, and seemlessly, ie. no suđden lurch. The CVT design can not experience lurch occurances long term because it would be damaged. That's why a precise and smooth engine was a requirement. And that's one reason the CVT, an old concept, was never really in production with a regular and imprecise combustion engine. The regular automatic transmission is not a good design preference conceptually compared to the CVT, but it can take punishment better. Good luck. BTW, you're not going to take my 400h! I don't let a good thing go that easy. |

Replying to: gunner (Jul 28, 2005 11:07 pm) Last week I had to do several short mileage trips. I was not surprised to see my mileage drop to 23 mpg. Numerous short trips are a mileage killer. The same short mileage trips in my former RX300 gave me 17-18 mpg. From your post I can see that you enjoyed much better mileage on longer trips.

Replying to: timothyt (Jul 26, 2005 4:53 pm) You are not in error when you reported unexpected acceleration when the ICE kicked in... I experienced a very similiar situation when I prepared for a right hand turn from a fast moving highway. as I proceeded to turn into the sidestreet the ICE kicked in and the vehicle 'lurched' forward directly towards another vehicle which was in the intersection waiting to turn onto the highway. I slammed on the brakes, thereby initiating a shutdown of the ICE and swerved to the right. I definetely think there is a problem here that Toyota NEEDS TO ADDRESS !!! BTW my mileage has also been poor with 26 mpg on the forst tank...did the dealer put something in the tank ????? to 24.3 to 23.2mpg.....hell, my 1990 4 runner with a 3.0 V6 got consistent 22 mpg. Fellow Hybid Types, lets not sweep this problem under the carpet. Sorry to those of you who paid close to 50K for a vehicle that does not perform as advertised, as I have for close to 40K....

Replying to: timothyt (Jul 25, 2005 5:33 pm) Re the engine kicking in --- all cars have idiosincracys. How long have you been driving ?? This is a fine handling, driving car. sounds like you're a Chevy guy.

Replying to: hibred (Aug 09, 2005 6:22 am) A similar thing happened on steering problems. Some people were complaining about pull in their steering and some of us had Rx400's that tracked straight. Some dealers initially brushed off the owner complaints, but there are owners who have gotten it fixed (and at least one reported it was a learning problem). I wonder if some dealer techs aren't following the proper set up proceedures (or if Lexus is working bugs out of their set up process). |
