car windows completely open on their own.

Auto open is a feature that can be utilized by 'holding' the unlock button on the remote down for 3 seconds... Try it ... Now at 'some point' - that same thing inadvertently happened! Dealer can disable this if desired, but it can come in handy on a hot day, if it's used as you're 'approaching' the vehicle from a distance - hot air can escape and help cool the interior before you get in... Just saying.
