Sorry to hear about your front window. It's definitely not as common as rear windows having that issue, so it's a new to most people. Could be anything from a misaligned track to a worn-out window regulator or even a problem with the motor. Since it's the front window, I'd probably avoid messing with it too much myself. Probably best to take it to a trusted mechanic and have them diagnose the problem. Hopefully, it's a simple fix.
