Can't be sure about the Gen 3 GS but my 2006 IS250 was subject to phantom window opening until I found out what was causing it. In the settings it is possible to set things so that the windows can be opened and closed with a long press on the unlock and lock buttons respectively on the key fob. You can sometimes press these buttons accidentally, eg by bending down with the fob in your pocket or if something heavy is placed on the fob in the house, or if a child plays with the fob - the fob has quite a long range. You say it was tucked away, but is it possible something like this happened?

Both settings (which are independent) can be changed/disabled via Techstream or by a dealer (at a cost!)

My Gen 4 GS300h doesn't do it, but I don't know if that is because it's the default setting - I suspect so, or maybe it was changed by a previous owner and again it would be a Techstream setting to change it.

Interesting because, I had this gremlin when I had my Battery changed. It turned out that the windows needed recalibrating after Battery was changed...

Ok. Sorry to hear this gremlin of yours. I am guessing but think it could be with the security locking mechanism? when the windows open, are the doors still locked?

Flo, have you looked in your Handbook for items relating to Locking/Unlocking ?

On my 2009 GS 450h this action can be set by the owner so can therefore be disabled. If it was activated accidentally and the doors not opened then the doors would automatically re-lock but the windows would remain down. Also test whether it is set up to do this by locking then unlocking with a very long press on the unlock button, that will then give you an indication as to whether there is a fault. This happened to me immediately after locking my car and walking away. A friend had parked next to me shortly after I had left the car and remained with it till I returned and time checks showed it could only have happened as I walked away.

Is there a second keyfob?  Perhaps this is the source of the issue.

Hi,

My brother had this happen a few times to his 2006 IS250 parked at home (keys not in pocket) and also when parked at work. 2nd Gen IS250's have the same long press unlock to open all windows active by default, disabled the option with Techstream and it hasn't done it since!

Still doesn't explain why it does it though.......

[johnatg]

I wonder if it could be caused by some sort of spurious radio signal received from the wider world - I guess it just has to be the correct frequency for a very short period - speculating that the long press on the key fob - which we know does it - actually causes a switch to a short burst of the correct frequency for opening the windows after a period of a few seconds? It does seem to be that often the behaviour is completely unexplained - when my IS250 did it I never thought that I had done anything to accidentally press the fob button. (Although I do know with other cars that crouching down to work on the wheels, for example, if I have the fob in my pocket the central locking will often lock and unlock almost randomly!)

Disabling the facility via Techstream of course switches the function off in the car, not in the key fob - so it is a permanent solution.

Thank you so much guys , i have a look on amazon for Techstream  but are lots of them ...any links for , i just don t want to get a wrong one , thank you again 

[C Andrew Green]

@Mr.Flo No idea about what's on amazon, mine came from eBay, however I've previously seen this one recomended as it says it works on 64 bit Windows.

They all claim to work on 64 bit Windows but I had to reinstall 32 bit Windows on a spare laptop to make mine work....

My wife got a Lexus Dealer to disable it.

Never happened again ...
