Rain Sensor Malfunction Mach e

[MCarl33]

My 2021 Mach E Premium windshield wipers come on, sometimes, with one sweep and stops. This happens when I start the car on a clear dry day . Other than that they work like they should on a raining day. I keep the rain sensing function on all the time. Only way to stop this from happening is to turn function off using the lever on the steering column. Does anyone know if this known software bug or a problem with the rain sensor unit on the windshield?

Neither. It's a characteristic of the type of sensor used. Your best bet is to move the stalk to Off unless it's actually raining.

Check your rain sensor (circle) and make sure it looks fully wet/dark. If there's an air bubble like this person has it won't work right:

Maybe try turning off the courtesy wipe setting.

Maybe try turning off the courtesy wipe setting.

That setting provides an extra wipe after using the washer. It’s unrelated.

I get it sometimes and put it down to dust or a shadow on sensor confusing it when I start the car.
