I drive a 2010 RX 350 and was told that mileage would improve with use. Sure enough I got better mileage after about a year. In my opinion those manufacturer supplied mileage figures don't apply unless you pay religious attention to the ECO light on your dash. Also, at my last maintenance appointment two months ago the dealer installed an update to the computer firmware that supposedly improves performance.

Did you ever think that this may be a "feature?" Using the cruise control will inevitably give you worse gas mileage. Maybe the designers feel that you do not want to see all the mileage data since you turned cruise control on. When you turn it off the display returns to the previous setting. Don't get the idea that I like this "feature" though.

I tried holding down the open button on my remote and yes, it did cause the windows and skylight to start opening but the opening stopped immediately when I released the button. I tried it twice. This is not the behavior I experienced and described in my previous post. In other words the windows, door locks, and skylight opened all the way with no hesitation and I was not accidentally leaning or pressing on my remote which was in my pocket. I am still investigating.

This happened to me when I was moving around inside my 2010 RX350 in a parking lot a month ago. The car beeped and all the windows including the skylight opened. I looked up to see a group of teenagers walking by holding some kind of black box device. I assumed it to be a game console of some kind. Not knowing any better I then assumed some spurious radiation from the device must have affected my car. It happened again a couple of weeks later while I was again moving around inside my car. However, there was no one around outside. Maybe this is a benign Lexus abnormality but I am concerned that there is electronic hacking of some sort going on and I am in the process of investigating it.
