It happens very often to me.

When i turn off the car and I do the one-touch closing of the windows, they arrive at the top and than go back down as they found an obstacle.

It also often happens when I close the windows using the long touch on the key, and that's more annoying since I've to get back into the car to close them.

Does it happens only to me?

I've tried to set up again full open and full closed position, but the problem (if we can call it a problem) always come back.

That is definitely, 100% happening because you laughed at those of us discussing our mpg figures

I can't say I've ever experienced that problem on either my 718 or on my previous Porsche's, though I once experienced a similar problem on the drivers door of an Audi I once owned.

If you haven't done so already you could try re-setting the window mechanisms. Page 305 | 2017-2019 718 Boxster Manual | Porsche iManuals It'll be the same procedure for both Boxster & Cayman.

Failing that try a suitable rubber seal lubricant, it's possible that the windows might just be binding a little tightly against the rubber. (Referring back to the Audi it was rubber lubricant that did the trick).

Thats my suspect..I'll try to do that

I have this happen on occasion and I suspect this is it:

Sometimes I have to open and shut the door to, presumably, get the door to move slightly with respect to the top window rubber sealant. Window will then go up and stay up. I am hoping in time the rubber will wear down just enough such that this never happens. But rubber lubricant would be a good thing to try.

Yeah, happens in mine, too.

 

[718S]

Oh my! This just happened to me today a few times. Only had the 718 for a week and it never did it before today... then it just started working! Has anyone brought it to the shop? For now I lubed the rubber just in case it tries to happen again.

For testing if it's lube I recommend talcum powder on the rubber. If that fixes it, when the talc wears off either add more or clean the rubber and use a thin, thin, thin coating of krytox.
