Front window motors slower than rears?

[coolprius]

My rear windows roll up and down just fine.
The ones in the front sound like they're struggling to roll up.

Anybody else experience this?

My guess is that Tesla kept the same motors to lift the windows despite adding dual pane glass to the front windows which weigh much more.

Yup I feel as if it's the dual pane windows are much thicker. My windows won't go all the way up on the first try.

Not only do my front windows roll down/up slower than rears (as the OP) and makes those struggling sounds, but my front passenger window rolls slower than the front driver! From a fully down position, the passenger window takes 2 seconds longer to close than the driver.

I took it to the SC the first week I got my car and they replaced the passenger window regulator/motor. But the problem persisted and they told me to piss off saying it's "within spec", and there's nothing else to adjust on the window motors.
