Anyone if it's normal for the windshield wipers to move slightly once at a stop on a perfectly sunny day? happens quite often and am just curious.

 

Yes, it is normal, it will move a bit even though not on. I think it is due to the automatic side, it will move a bit every now and then.

 

Audi does this as well. It’s move/fip the blades every once and a while for longer wiper life.

 

You're kidding me? First time Porsche owner and I thought I was going down the road of "non-repeating at the service department" electrical bugs. That's very interesting, will have to read up.

 

It's a nice feature, if the wipers set too long in one position, then the rubber conforms to that position and you have to replace the blades sooner. A lot of these cars never go out in the rain, as such the wipers can stay in one position a very long time without this feature.

The windows do the same thing (at least on a Cabriolet).

 

Never noticed it. And, indeed, mine has yet to see rain.

 

All of my Porsche models I’ve owned have done this. The first time I had it happen, I thought I had a problem….Now I don’t even notice it!

 

I noticed today while parked idling waiting for my wife.

Glad to see it is normal.

 

Is that why the passenger side window sometimes moves? Seems silly. I don't like the idea of electric motors wearing out from unnecessary overuse.

 

Our VW Alltrack does this too ... lol

 

I thought the same thing, too. Was relieved to find out it was by design to keep extend wiper blade effectiveness.
