It's maddening. Intermittent to nuclear in about 8 seconds, everytime.

I've spent some time cruising this forum and this seems to be a common issue across many MB models. That just blows my mind.

Anyway, is it a simple reprogram at the dealer level?

Have few small issue that need to be addressed and I hate taking a car in for service, but things are adding up that shouldn't be adding up.

Thanks.

I'm not sure there's a fix for this, it seems to be a safety feature. Mine will do the same but it doesn't bother me because it's been fairly accurate and goes nuclear when it should.

My wipers seem to think that a single drop of rain is cause to go into hyper drive. I hate the rain sensing feature. Just let me set a speed, for god sake.

You can force it to slow or fast I believe. On the stalk the two dashed line settings are sensing slow/aggressive, and the solid ones are manual slow/fast. Don't know if that helps.

The feature works pretty well for me. It gets a little confused at times by morning mist if I park outside. It seems to think the windshield still is slightly wet even after clearing it.

Same here, never had any problems. I think some cars must have sensors that are defective. I keep mine on the slowest auto setting and they pretty much always work as they should. Every once in a while, they'll wipe once on a clear sunny day right after I start it up, but that's about it.

There is most certainly something wrong with the sensor on my vehicle as I never see the slow speed wipers, let alone an intermittent wipe, unless I'm stopped or under 10 mph.

We'll see what the dealer has to say.

I'm aware that the wipe interval is selectable. I light rain, I don't want the wipers to go off at all until there is some reasonable accumulation of drops on the windshield. The idiot wipers see a single drop as cause to launch an all out assault even when set on the longest interval.

If I'm not mistaken, the point of the rain sensing ability is for the car to detect how much water is present and decide how often a wipe is needed, thus taking that control completely away from the driver. In reality, what this turns into is a huge annoyance that causes me to turn off the wipers completely and do the needed wiping manually by pushing the button on the end of the stalk to get one swipe when desired.

I haven't found my '16 GL450 wipers to be hyper. About the only time I seem them kick in to a really high speed is if the rainfall is heavy, or if I'm just starting out and accumulated drops roll off the roof and over the sensor. The wipers calm right down after that.

Each to their own. When the rain is very light and I want a swipe maybe every 10 or 15 seconds, the (retarded) "brain" controlling the wipers swipes nearly continuously. Just let me handle my own wipers, please. It's a tough, dangerous and exhausting job, but I live on the edge and am up to it.

Just love this feature. It works well for me at the 2 level sensing, super sensitive and normal.

Mike450

That's how I imagine it is designed to work. Unfortunately, that's not what mine does. Not even close.

It is quite comical on how fast the wipers can go - it's like on steroids.

GL-

Indeed. In heavy winter weather, the speed is adequate for flinging ice off the tips of the wipers.

Just made a trip half-way across the US, and it was amusing when the wipers came on when I splattered an insect in the area of the sensor. Better than a co-worker that has a Range Rover with sensing wipers and had bird droppings make a direct hit to the sensor, to only be smeared across the windshield.

If you have control issues, just manually select your wiper speed.

Dog hauler

But that's the problem. With intermittent mode, you can't effectively select the interval. The damned sensor is determined to get every last drop of water no matter how small and to do so seemingly even before it hits the glass. Even in very light sprinkles, the sensor swipes the wipers almost with no hesitation, let alone stops, between swipes.

Somebody at MB needs to teach the sensor the meaning of intermittent.

I'm glad I'm not the only one with this issue! The wipers work as they should for about the first hour of driving. After that, they seem to wipe constantly, regardless of how fast the rain is falling or the speed of the vehicle. If I shut the car off & then start it back up, the windshield wipers behave as they should. I guess I just have to "reboot" the car every so often.

Our Lexus LS460 goes hyper in about 8 seconds too.

Rain sensor "interval" is also speed dependent.. at a stop slower ... on the move higher speed

After I read this post, I made a post to check (rainy in Seattle yesterday) and my wipers seem very adaptive to the amount of rainfall. They seem to be doing the right thing. There is usually a light sprinkle in Seattle, so it should never go nuclear. They seem to work!

Love this feature. Mine are magical. They are never too fast or too slow. They seem just right every time at any speed

Just got my used 2016 GL450 and I absolutely LOVE this vehicle....except for the wacky wipers. I haven't driven any long distances in the rain but the wipers start off normal and then go to warp speed in less than a minute, even in light rain. There are so many buttons and features on this vehicle that I thought maybe I was just doing something wrong. I guess I will just need to live with this, as this post seems to say there is no remedy. I will just continue manually turning them on and off.
