On [XXX], while driving highways for over 2 hours, the windshield became very dirty with dried debris from the road. I activated the window cleaning function on the steering wheel ( for the first time) and could not clear the dirt from the passenger side. I tried many times, but no result. The drivers side did clean acceptably. But not the passenger side! I could see arcs on the windshield where the wiper attempted to drop fluid. There were 8 or 9 such arcs left after the wiper withdrew. I did see cleaning solvent near the outside of the windshield. But I could not see out of the windshield. Reported same to Teslas customer svc and a service visit was scheduled for Jan. 8, 2025. By this time I had manually cleaned the window and verified the solvent well was full. Svc agent said, no one else complaining and system is operating 100% as designed. Experienced same situation again on [XXX]. Customer svc again scheduled an on site svc call for Feb 7 2025. I then saw on facebook, over 50 other people complaining of exactly the same problem. Most had tried svc and heard the same informational as I. Some included photos of the problem, some had their wiper or pump replaced, other e told that Tesla was planning an OTA update to cure the problem. I did a walk-in to svc on Jan 27,2025, and was told there is no guidance from corporate on this matter and that as far as they knew, corporate was not aware of the problem. I’ll keep my appointment on Fri and hopefully I’ll have some relief. I hate not seeing things coming from my right side!
