Wiper Constantly Squeaks - Anyone found a solution?

[GmP]

I sprayed some ceramic coating on mine, Hydrosilex from Amazon, problem solved.

Sorry for the late and maybe dumb question: you spray the wiper blade or the window?

Does everyone else's wiper constantly squeak/screech? The wiper is my biggest issue with the CT. Whenever there's anything less than heavy rain, the wiper screeches/squeaks on the upstroke which is very audible in the cabin and also outside the car (I see people outside notice).

I already complained in my last service appointment, but they said it was "within spec"

Would applying a ceramic coating help?

I've never used anything but regular windshield cleaning solution and normal truck washing using soap and water. No, it doesn't squeak. Never has.

My windshield wiper has always operated multiple times during every trip when it's not raining. Ironically, sometimes it doesn't work when it is raining. I don't remember but my friend said that it did not squeak or, rather, screech in the beginning but it has been for a while, probably because it keeps wiping on a dry windshield.

The windshield wiper and rear view camera are the two only complaints I have about the Cybertruck and they are both horrendous failures. It seems obvious to me that Elon Musk does not drive the Cybertruck because if he did he would have had these problems fixed before they ever started selling it, and if he drove it now he would assign engineers to fix it immediately.
