Windshield Wiper Auto Function not good

[Msg43]

When the Windshield Wiper is set to Auto I find the following:
1. When there is rain sitting on the windshield the wipers often don't trigger.
2. Sometimes when there is no rain and the windshield is clear the wipers will still trigger.

I have seen some definite variability in their performance. Most times they work fine. When they fail to trigger, I have found it is usually very light rain, and manually triggering them once will often get them to keep working. No idea what causes the false triggers. The other weird behavior I see is that the majority of the time when I depress the brake pedal to put it in D or R when first getting into the vehicle, it triggers the wipers one time. My suspicion is that the sensor just triggers with anything coming near it, not just water. Maybe any dirt/dust debris.

The third suboptimal behavior I have seen is in a very light rain when they should have a longer interval, they sometimes get "stuck" in a higher frequency like it was pouring.

But I have no idea what kind of sensor it is, where it is, or how these things even work. I was never a car guy and never cared about the tech of cars.

I might be the only one that never read the entire manual cover to cover, but I only recently learned that a single quick push on the outer button manually triggers one pass. Same one you hold in longer to trigger the windshield washers. Prior to that I was cycling from auto to manual modes just to trigger them once when the auto failed.

I feel like I need mine to be at least 15-20% more aggressive.

They are both too slow to act and overall too slow.

So far mine have worked wonderfully. I've never had to adjust anything. I've had a number of cars with auto wipers and the R1T and my GX 460 are the only ones I've never needed to intervene with.

Im not a big fan of the wipers. I wish they were like in my BMW where in auto you could adjust the sensitivity. I just manually do one swipe every once in a while to keep up.

Completely agree with this.

I also get the random wipes. While not a big deal, i do find it annoying.

Oh wow! I didn't realize that was a thing! I have the same thing happen and I just figured I had done something wrong! Hah!

I agree with this 100%.

This is my experience exactly, but the only thing that really bothers me is they are not sensitive enough to light rain cover on windshield and feel like they don't activate quickly enough. I find myself constantly bumping the washer button at end of stalk to get a single wipe in light rain / road mist. It's to the point where I feel it's a little dangerous in these conditions to wait for the sensor activation, as the windshield becomes too obscured. Hopefully, it's not a sensor issue and is the sensitivity can just be adjusted via a SW update, or better yet, give the user/owner ability to adjust sensitivity themselves.

I think I’m also finding that I feel the “Shower” setting should not be intermittent. A “shower” to me is a constant thing. It seems like the wipers are making it to the Shower setting, but that setting is too long of an interval to be useful for a shower.

To get from “auto-selected-shower” (unuseable) to “downpour” (useable Shower setting) is A LOT of clicking.

Here’s a clip from yesterday during light rain. Including a vid to judge if I’m overreacting.

I’ve considered buying rainX if it’s going to be like this and need this much button pressing to adjust out

Thx for this, had to keep turning to on and off the other morning when I had heavy dew on the roof that kept rolling down the ws when I stopped. Mine too does random swipes, usually on initial shift as others mentioned.

I agree, they are not sensitive enough, especially when it is dark outside. I find myself having to push the manual wipe button a lot at the end of the stalk during light rain.

I agree, they're slow at all speed and need a reprogramming.

For me also not sensitive enough. I searched the manual, dig through the menu options, but couldn't find anything to adjust the sensitivity. My last car had rain sensing and sensitivity customization. Maybe addressable with a software update.

Yep, mine regularly takes *JUST* longer than I'd like. I often find myself tapping the "wash" button quickly to force it to wipe. But if I grin and bear it, it'll go off 1-3 seconds after I notice how badly I want it to wipe.

At least it doesn't do what my BMW I3's auto-wipers did - go from "far too infrequent" to "OMG! YOU'RE IN A HURRICANE OF TORRENTIAL DOWNPUR!" when there's only a light drizzle.
