Unconfirmed report: 2026 Model Y Performance wipers activate unexpectedly

📍 Reddit Tesla FSD

Unconfirmed: an owner of a 2026 Tesla Model Y Performance reports on a community forum that, after a software update installed the previous day, the vehicle began spraying washer fluid very aggressively and running the wipers up to about the midpoint of the windshield. According to the account, the cycle repeats twice during his morning commute, around 6:45 AM. The author asks whether other users with the same model have seen the behavior. The post does not state the software version and includes no confirmation from Tesla, and the source text appears cut off before the description ends.

🔎 Why it matters: No official confirmation: the post attributes washer and wiper activation on a 2026 Model Y Performance to a software update installed the previous day, and the author only asks whether other owners have seen the same behavior.
📈 Upside: Not applicable.
📉 Risk: If the behavior repeats, the vehicle would keep activating washer and wipers with no identified cause in the report.
