I’ve got my sensitivity all the way down to lowest setting. Very rarely they’ll trigger while driving. But much more frequently they’ll trigger upon starting the car - if the car has been parked outside for an hour or so. First one wipe of the front, then one wipe if the rear a few seconds later. Perfectly clear day, no dust or pollen on windshield that I can see. I haven’t experienced the same thing when parked indoors.

In the grand scheme of things this is a minor bug but it’s just weird.

Man I had intended to take a video of the issue today but I forgot. I’ve got this bug narrowed down almost exclusively to one situation: when the car is parked outdoors for at least 30 minutes, the front wiper will trigger once upon starting the car, followed by the rear wiper a few seconds later. This never occurs when the car has been parked indoors, either in my home garage or parking garage. There’s no dust or pollen on the windshield that I can see.

Happens every time I drive my car to the gym during the day and leave it parked outside for an hour or so. It doesn’t happens when I park it more briefly during errands.

I wonder if sitting out in the sun is causing the issue? I don’t know why that would be. I’ll park it outside for an hour or so this evening to see if it happens.

There is a setting for the wipers to swipe once when you turn car on.

You can turn the wipers off by moving the lever up or down. I can never remember wish way.

Maybe... Just before you turn your vehicle off, the sensor registers a particular reading. Then when you start it again, the reading is sufficiently different then that last reading (🌎 moves relative to 🌞) or clouds.

So it determines that there may be something interfering with the sensor, causing the wipers to wipe... Then the rear wiper wipes because that's how they are setup...

Do you mean the courtesy wipe? That setting is just for if you clean your windshield with the washer fluid and it'll do an extra work after the normal wow had completed to get any investing drops

Move the stalk down 1 to the "off" position unless it is actually wet out. It's probably just an artifact of sun glare or something fooling the sensors.
