Mystery windshield wipe at start-up

[Mickey the T]

My Fusion used to do this all the time when I would pull into my garage, no clue why. I think it’s a Ford thing.

Since this is my first Ford in 35 years, the mystery wipe makes me feel like I'm part of the club.

If the issue is the courtesy wipe that is referred to on page 95, then my car is only deciding to be courteous when it's the mood to do so...

Still worth turning the setting off to see if the behavior you noticed stops.

Agree. Since it's intermittent, it will take me a while to actually realize that a setting change has fixed it. Sort of like when realizing your hiccups have finally gone away.

I occasionally get a phantom wipe when I start the car. It doesn't bother me. I prefer to leave the wipers in Auto.

Exactly. That's kinda the point of Auto -- for it to be automatic. I leave my Escape on Auto all the time and it doesn't do that.

Fortunately it's only a minor annoyance. I'm just getting used to it. One more Mach-E quirk.

Mine is off that is not it. It started with 1.6.0 can almost guarantee that. I think just turning them off until it rains will do it. A sticky on the dash may help you remember how to activate it when it rains the two times over your ownership.

assume you mean with the selection to auto wipe on? It happens occasionally on mine, but it also happened on both my alfas with the same setup.

Dust on the window...

I was getting this too right after an update and after about a week it hasn’t happened since. Minor settings like rear camera delay are also sticking for the first time so maybe there was another update that fixed it or it fixed itself? Either way I’m not getting the 1 start up wipe anymore which is great because I was worried about dry scratches.

It happens to me, too. It isn’t “dust on the window” and it isn’t the “courtesy wipe” noted in the manual. It’s just a “bug” of sorts that has to with either heat or sunlight tricking the sensor when you leave the car parked outside during mostly sunny days. You’ll get the same single wipe of your rear windshield wiper when you put the car in reverse.

The only “fix” is to turn the wipers from Automatic to Off. Put them back on auto if it starts raining.

Solved.

Mine is not parked outside...

Thank you. But what is this "rain" that you speak of?

Same... Bug and only fix is turning auto off.

This is something that my MME and Lincoln MKZ used to do too. Typically related to sun/visibility of the camera and system trying to clear and make it more visible.

FYI - courtesy wipe is when you use the windshield wiper fluid and it'll do it's normal wipes then delay and do another shortly after to catch any delayed washer dribbles. Same feature as my MKZ as well.

It's not a "bug" or unique to Ford. Every vehicle I've ever owned with rain sensing wipers does this.

And on every one of them the solution, if you care enough about it to make it stop, is to turn the wipers off.

It's good to know (I suppose) that others have the same issue. I thought that maybe I was crazy, or possibly doing something wrong. (Two things that are still quite possibly true.)

That said, I have had three BMWs over the past ~20 years with auto rain sensing wipers and I've never experienced that in any of those cars. Maybe the sensitivity default was different? At any rate, I have some excellent suggestions as to how to deal with this. And it's such a tiny issue in the great scheme of things. I was mainly wondering if I was just doing something silly.
