From the article: This issue arises because the Cybertruck’s powerful single wiper doesn’t always spray enough windshield wiper fluid to break down all the salt kicked up by other vehicles. At highway speeds, salt accumulates rapidly, and it’s even possible for the Cybertruck’s forward camera cluster to get blocked, which may trigger a request for the driver to take over. The solution to this issue is simple: apply more fluid to the windshield to help break up the salt, which the Giga wiper can then wipe away. Currently, washer fluid is only sprayed during downstrokes, and holding down the wiper button just repeats the cycle. However, according to a post on X by Wes Morril, Cybertruck’s Lead Engineer, that’s about to change. With the upcoming software update 2025.2.8, which is expected to roll out to Cybertruck owners in the next few days, Tesla has introduced a new feature for the washer button. Now, holding down the button for two full cycles (two sweeps of the wiper) will continuously soak the windshield. This means you’ll be able to apply double the amount of fluid — on upward and downward wiper strokes. This is a highly requested improvement, particularly from Cybertruck owners in regions where road salt is frequently used during winter. While the winter season is nearing its end in much of North America, this update will be a welcomed improvement for next year’s colder months.

Kind of awesome that they can modify even software that just controls how much fluid is sprayed via the wiper by just an OTA update. In many cars this is likely hard coded or at best you can take the ECU out and flash it

Meanwhile old vehicles had separate controls for wiping and spraying. You could spray whenever and however you liked. Why can't we have this today?

Great….. Now allow us to actually shut the wiper off completely because the false triggers dry wiping and smearing fine salt particles into a solid haze all over the glass is the only reason we need to clean it in the first place. And yes, I know you can select off in the wiper menu but FSD will turn it right back on when you drive under an overpass and it triggers the wiper for no reason at all. Half a decade plus of removing rain sensors and somehow the vision autowipe product is getting worse and worse over time it’s insane. The wiper system on the truck is literally the worst part of the truck currently and it’s all software screwups that Tesla refuses to address.

Even decades old cars would always have some sort of courtesy wipe either before and or after the what was coming out. It’s the annoying thing in a lot of cars that it would wipe one or two extra times which, in the winter, would make new streaks. Defeating the purpose of using the fluid.

Wish we could get this for other cars too. My Y suffers badly from dry upper windshield. I know some models supposedly got the possibility to add more by pushing the washer button, but certainly does not work on mine.

Not sure if the S3XY Buttons products are available for Cybertruck, but the autowiper supression functionality alone is worth buying the Commander for.

I’ve been hoping that they will come out with them it’s all I want at this point to make the truck perfect so to speak. Currently there is nothing to be found on their site for the Cybertruck.

As far as I’ve understood the network on the Cybertruck is much harder to work with than regular CAN-buses.

I figured as much. I don’t expect improvements any time soon. Would be nice if Tesla would just either solve the problem with false triggers on the wiper or concede power back to the drivers on the wiper and just simply allow us to fully shut it off even if FSD is active for now until they can actually figure it out. The current behavior of taking a mostly clear view and smearing it over the cameras which the car isn’t capable of clearing (hopefully will be after this update) is just insane.

A rain sensor would have gone a long way

I think you’ll find once you can actually get the window clean with the new update that the false triggers will become less frequent as well.

You can turn it off while using FSD. It'll be on by default every time you engage FSD, but you can turn it off and it'll stay off until the next time you engage it.

That’s not how it works. Yes, you can turn it off but while in FSD it still turns back on over and over as the truck thinks it needs it. So for my 45 minute commute I turn it off probably 5-6 times whenever I drive under an overpass.

Are you engaging FSD more than once during the drive? I don't think I've ever experienced it turning on after I turn it off, unless I disengage FSD and reengage it. My guess is you're taking over to avoid a pothole or something and then engaging FSD again.

No. FSD is crazy good I’m running it from my driveway to my office with zero interruption. I’m also in a Cybertruck which is a different software branch than their other vehicles so maybe that’s the difference? All I know is it is turning on over and over and I can specifically tell it’s set to on because when the wiper on the cyber truck engages it wipes and then stays in the down position for a while when active. When I set it to off after it triggers it instantly resets to the up position.

it's super crazy that Tesla could do all these with OTA software-while GM took so long to fix my Bolt EV seat belt recall.

Hm, I guess that's possible. I drive a Model 3.

Other cars do proper and thorough preproduction testing to suss out these kind of issues so they don’t have to be fixed post sale. Tesla pushes out unfinished cars and beta features but sell it to the customer as they can “improve” the car with updates later.

That’s one perspective. The other is that Tesla’s forethought in software allows for creative solutions as issues arise.

Credit to Tesla and their software development. I still use the ‘close the lid gently’ as a good example of their attention to detail on the software front.

If you fidget with the cover, it still assumes you're closing it too hard.

On the face of it, vision should be enough to control the wipers, but I think the reality is that the physical area of the windshield it sees is way too small. Imagine if you're only looking at a tiny square inch of the windshield, you'd probably have trouble gauging just how often you need to wipe too. But when it's fully autonomous, that won't matter anymore. It would just wipe when it can't see clearly, no human preference needs to be taken into consideration (for the most post).

Can they put out an update that stops the body panels from falling off?

Ha ha, this is so naive… I don’t disagree that Tesla pushes out buggy stuff. But other brands are no better. The biggest difference is that Tesla actively fixes problems in a way that is no hassle to the owner.

You know what’d be better? If holding down the windshield wash button continuously sprayed the windshield…like every other car on the market. Stop praising Tesla for fixing a problem it created

I'll take the move fast and fix it later over what you bought is locked in time for the next decade with no updates.

why is adding a $5 rain censor so hard, its a proven technology since like what, the 90s? Technology besides tesla usually gets better not worse

When does the 20 gallon wiper fluid tank upgrade go in? /s A bath of wiper fluid obscures clear viewing too.  Sounds like a fundamental design issue.

Their camera rain sensing technology hasnt worked since it started. Rather ran spending probably 10s of millions already for like 10yrs already , just add rain censor everyones happy. Imaging having a car where rain censor doesnt work in locations like seattle or vancouver whrre it rains like half the year.

nope thats why clickbait works on everyone

"Only sprayed during downstrokes" - my Cybertruck only sprays on *upstrokes*, which is much worse, since the spray comes out of the wiper blade itself, so very little of it hits the windshield before being pushed upward, especially at speed. I poked additional holes in mine. It didn't help. Fundamentally, I think a more powerful pump is needed, and there needs to be a greater distribution of washer fluid to the upper part of the wiper, since the surface area it cleans is much greater than the lower part (on which spraying actually works). But glad they continue to work on it - it's a significant issue in that it makes FSD unusable in winter conditions.

Requiring software update for wipers.. This is what the world has come to.
