2025.2.8 upgrades/fixes: windshield fluid spray, rear cross traffic notification

[b4mytruck]

Isn't this a bit redundant though? I just listen for the screams personally. If I have a chime going off as well....that kinda breaks the immersion

I love my wife's GMC Yukon, I has directional haptic feedback in the seat. Let's my passengers have less anxiety about car warnings.

I rented one of those once, kept riding the lane lines to get a back massage

Do you have any pictures of what your old wiper was doing to windshield? I got a "revised" blade too but it was no better.... I wonder if some people are complaining about the new blade... Can you show a picture of your old windshield streaks? Please

I checked, and I do not have any pictures of what it was doing, but it was smearing like crazy and hardly any fluid was coming out at all. Had to go to the car wash daily to clean the windshield or manually do it myself.


Tesla’s part numbers follow a structured format. Listed is the part number they gave me:

1853252-97-D

1853252 – The base part number, which identifies the specific component across Tesla’s catalog. This number is unique to the Cybertruck wiper blade.

97 – This is typically a variant code that may indicate fitment specifics, regional differences, or minor revisions of the part.

D – The revision level of the part. Tesla uses letters (A, B, C, D, etc.) to track revisions. A “D” revision means this is the fourth major revision of this part.

This system helps Tesla track improvements and changes while ensuring compatibility across different vehicle builds and production years. If a newer revision comes out, the last letter will change (e.g., from D to E).

Did it look like this? This is the way mine looks before and after "revised" arm

Yes exactly and I have the new arm also. If washer dispensing fluid issue did not resolve itself with the new wiper blade. I was going to run warm water with a little bit of vinegar in it along with running compressed air through that also at the end.

You can disconnect one of the connection points for the hose line to do that which should help. You could have something clogged or build up in there. SC said the holes in the old wiper blade were too small and not dispensing fluid properly. Hence the new part number.

Thought I'd share my wiper arm and blade part number, which got installed on a Feb 3 service appointment: 1853255-00-E.

So, I got revision E. My CT was built on November 15, 2024.

Honestly, no real improvement. The one thing I've noticed is while I don't see fluid being sprayed from the blade that goes over the passenger side, there is a lot of fluid that gets built up or wiped off by the tip of the blade on the passenger side. So, there is fluid coming out...guess I haven't looked close enough to see it.

Same, this is the replacement I got. Still no good.

This sounds to me like it is pump related or hose related. If you are only getting some fluid on the drivers side and not hardly any on the passenger then it’s unable to create enough pressure.

Maybe we should be checking the hoses and look for restrictions or it collapsing. but since the blade resolved mine…….. Another thought is comparing the washer fluid motor part numbers and revisions. My truck is early VIN in the 4000’s. It’s possible there is a bad batch of them or that it’s a new supplier.

Can one of you guys do a flush with warm water and vinegar and then some compressed air then post your results?

I would suggest removing the wiper blade first and detaching the line from it to clear out any debris without putting more of it into your wiper blade. Then flush the blade out separate and re-attach it.

Then use an approved washer solution that is not hydrophobic like Rain X. This may fix it.

Also, don’t forget to check for any leaks or kinks going to the front camera washer on the bumper it could be losing pressure there.

Sounds like you're on the older blade version, the new one has better sprayers and more universal pressure. The D version solved all my windshield issues. Addition of more water with also good improvement

THIS.

I do not understand. I have the blade my car was delivered with and Tesla has never offered me another despite repeated notifications that the blade isn’t working as intended/needed. Do I have to go to the NHTSA and tell them about this? I have plenty of pictorial and video evidence to prove that the blade is inadequate.

Ask for Revision “D” for the wiper blade and see if that fixes it. I saw another post here about “E” which is assumably the next revision, but all I can speak for is “D”

Also try those steps mentioned above about flushing it and see if that helps. It won’t take long to do and will give you faster potential resolve than waiting for NHTSA to do anything. That could take months and likely never happen. The “flush” is about a 30 minute job and is worth a shot. Let us know how it goes and if that resolves it. I would do it but Revision “D” along with the new wiper motor resolved my fluid issues fortunately.


1. Remove Wiper Blade & Detach Line – Take off the wiper blade and disconnect the washer fluid line to prevent debris from being pushed into the blade.


2. Flush the Wiper Blade Separately – Clean out the blade before reattaching it to ensure no blockages remain.


3. Check for Restrictions – Inspect hoses for any blockages, collapses, or restrictions that may be affecting pressure.


4. Flush with Warm Water & Vinegar – Run a mixture of warm water and vinegar through the system to help dissolve any buildup.


5. Use Compressed Air – Blow compressed air through the lines to remove any remaining debris or clogs.


6. Use a Proper Washer Solution – Refill with a non-hydrophobic washer fluid (avoid products like Rain-X).


7. Check for Leaks – Inspect the front camera washer line on the bumper for leaks or kinks that could be causing pressure loss.


8. Test & Observe – After completing the flush, test the system and monitor performance, then report findings.

First post in this thread implies that this update includes rear cross-traffic chimes for the cybertruck
According to not atesla app, CT isn’t getting it yet.

some do

Are you certain this image came from a cybertruck?
Because that would contradict the release notes (link below)

when is this coming to the CT?

It is dropping, now....

It was confirmed in this video right at the beginning(first minute of this video) last night. This video shows Chuck Cook downloading it in his truck and showed the wiper fluid updated feature:

I stand corrected.
Clearly Not a Tesla App got the notes wrong.
Happily…
