Hi guys,

I've had my 2018 GLE 43 for about a month, the rear windshield wiper seems to randomly swipe one time when I activate the front wipers for either one sweep or turning it to rain-sensing. This is really annoying because there's usually not enough rain that I need the rear wiper to be on. Also it leaves an annoying mark on the rear glass! Sometimes when there is a lot of water accumulated on the front and rear windshields, activating the front wiper will simultaneously operate the rear. I have the rear wipers in the off position. Is there a rain-sensor in the rear that might over-ride the off position?

Thanks!

couldn't say, but on my '16 if the front wipers are on in any position and you reverse the rear will swipe. this is regardless of on/off position on rear. ron

It’s a courtesy wipe. VW has a similar feature. I’m not aware of a rain sensor on the rear.

I like the auto rear single wipe when reverse gear is selected and the main wipers are engaged.

I am aware of the courtesy wipe, but the rear wiper occasionally does a single sweep when in Drive and I activate the front wipers. It's very strange!
