It happen to most 460 owners by accidents. The first it happened to me I didn't know my 460 had this feature. My fob was in my pocket and somehow the sunroof and windows partially open. So I had to check my manual to see what cause this to happen. Now I know why.

I realize we risk reviving a VERY old thread, but it sure would be nice if I could CLOSE the same windows from said FOB.

Well, this happened to me tonight on my recently purchased 2009 IS250. I thought the car was possessed, a few days short of Halloween!

So after all this time, what's the consensus? Is this always an accidental fob-push? Car-electronics glitch? Would having the dealer defeat this (mysteriously stupid) function in my fob prevent all further occurrences?

Thanks,

I've come out to my car a number of times within the last few weeks and just like the OP, all windows and moonroof were open on my 2007 GS450H. In fact, it just happened 2 times last night 5 minutes apart! I saw they were down so I rolled up the windows and moonroof myself, then set the keys down, then heard the car go 'Beep Beep' and they all opened up again so I KNOW it wasn't me pressing the key fob unlock button by accident as both fobs were on the counter. When this first started happening, I thought it might be a weak battery in one of the 2 fobs so I replaced them so I know it's not caused by a weak battery either.

I did read on another site that unlocking and locking the door manually can help. As you may know, holding the physical key in the door handle in the open position will open all windows and moonroof. The other expert said it's possible the actuator in the door handle is sticking in that position.

So I turned the key a few times in the door lock back and forth and let it sit over night. This morning, everything was shut. But upon coming home tonight and locking the doors with the remote, I again heard the 'beep beep' from the car and the windows/moon roof were open. I did notice as this was happening, the remote key fob light was flashing and I DEFINITELY didn't touch it. So I figured it must be the key fob causing the problem. So I took the battery out of the offending fob. But now here's the new twist. When I went out to roll up the windows, the front passenger window would roll up, hit the top, then go down half way. I could not get it to stay rolled up unless I left it open a tiny crack. As soon as it rolled up all the way, down it came, even when holding the window control in the 'up' position. Grrrr.

If the windows and moon roof stop rolling down, I'm going to say it's the fob.

Anyone know about the passenger window not staying up?

Pinch sensor on the passenger window is being activated. After it activates and opens halfway, you should be able to close it back up fully without it opening halfway again as the pinch sensor is deactivated and one touch close is also deactivated. I believe the pinch sensor is deactivated until you fully open the window and then fully close it to reset it otherwise things like one touch close won't work.

I think you are on the right track with suspecting the wireless remote key is defective as to the phantom moonroof and windows operation. And the only practical solution may be to replace it.

Thanks for the response...Unfortunately, the window cannot be closed without it rolling halfway down, even after it's been activated. I checked to make sure nothing is stuck in the window moulding that would cause the pinch sensor to activate and it's clean. Really frustrating.

Any other ideas on what to try?

I don't know about Lexus, but my Audi has a reset procedure where you fully open the window, keep the the switch pressed down for around 3 seconds and then close the window all the way up (first click, not second auto close click) and hold for 3 seconds. Not sure if this same procedure works on the Lexus or not, but it wouldn't hurt to try it. Also check to see if your car is throwing any codes related to window with Carista or something. If that still doesn't work, then it might be a good time to take the car in and have them take a look at it.

Our LS's have a reset procedure as well. It's in the manual, but it's also been outlined here at CL numerous times, so you should find it with a search.

Thanks! I found some guidance for resetting the Lexus windows. Here's what worked for me. I opened the window and continued to hold down the button for 10 seconds (I didn't hear a 'click' but I was at work and there was plenty of noise). Then I raised the window, holding the button in the 'up' position and continued holding it there for 10 seconds.

Voila! No more rolling down window! I hope it stays...

enoch861

Awesome! Glad you got it solved!
Now you just need to get your key replaced (most likely) and you should have a car that doesn't randomly roll it's windows down.

someone just posted the reset procedure a few posts up why dont you try that

Not the winders and moonroof but, my trunk was open one morning after a rain storm. I always keep my keys on my pocket, so I don't think about it. So what I did was get one of those rubber cases for the key FOB, and because it added more space and covers on buttons it's a little harder to push and I have never seen the same thing again.

I can see this happening once you have a few things in your pocket, like I do...

I am at the dealer now ... no trouble found. BUT I had this same problem on 2 BMW's a 2011 3 series and 2013 3 series. In both cases the dealer didn't know how to fix it (even though it was the same dealer in both cases). the problem in both cases turned out to be a defective switch in the driver's side door. On the 2011, the problem happened 3 times before the dealer called the national service line and found out it was the switch. On the 2013, I had the dealer look at the sevice record from the 2011, so that made it easier.

I just spoke with the Toyota service manager here and they are calling the region to see if there's a known problem.
