Tesla has made a software-related change to the Cybertruck’s wiper to improve tackling the buildup of salt and road grime on the windshield. If you’ve driven the Cybertruck in regions that salt their roads, you’ve likely experienced this firsthand. The image above shows the author’s truck after 90 minutes of highway driving.
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.
More Fluid
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.
Thanks for the feedback - If you hold the wash button through 2 cycles the wiper will now continuously soak your windshield, effectively doubling the amount of fluid dispensed. This helps with the stubborn road salt when needed and maintains the quick cleaning functionality for… https://t.co/wEqs9uLpBB
