My wife and I were dining alfresco at a local eatery and as I was sitting on the deck I looked over at my GS and noticed my windows were mysteriously glare free and clean as could be. On further inspection I realized all 4 windows were down and the moonroof open! I had some expensive electronics in the vehicle and business files/paperwork and thought to myself, "dang, what if I was INSIDE the restaurant and that happened, how vulnerable I'd have been to theft and on a lesser level but more damaging to the vehicle, what if it was downpouring rain and the car was unintentionally open to the elements! I know there's a setting to disallow the opening feature but I do like it on these 90 degree Chi-Town humid days...oh well but any ideas?

where do you keep your key? you sure something in your pocket didn't accidentally hold down the unlock button?

Pman6 called it. I had the same thing happen to me. Keep the key fob in a pocket without anything in it.

yup, if you hold down the unlock button it will lower your windows, and open the sunroof. I like to do this when its really hot to let the hot air in the car out.

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 in the last 5 minutes! I saw they were down so I rolled up the windows and moonroof myself, then set the keys down, then heard 'Beep Beep' and they all opened up again so I KNOW it wasn't me pressing the key fob unlock button by accident. 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 that 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. It's possible the actuator is sticking in that position.

I just worked the key open and close a few times...we'll see if that stops the problem. Thankfully, it's not pouring rain!

I actually found a long thread related to this issue of the windows and moon roof opening without pressing the key fob. I'm going to comment over there.
