98 Infiniti I30 Window's roll down after sitting in a parking lot?

[alscort93]

I know very little about Nissan/Infiniti's, unless it is a Nissan Forktruck, used to be a tech, but a friend of mine has a 98 I30, a few times she has walked out to her car at work, while it is locked up and windows and sunroof closed, to see that the windows have rolled down just a little bit, enough to put your hand in it. She said it's only happened a couple of times, but wants to know if this is something that she should get looked at since the car is warranted from where she bought it.
