Report: Juniper Model Y on 14.3.10 fails to restart at green light

📍 Reddit Tesla FSD

Unconfirmed: a Reddit user reports that their early 2026 Model Y Premium AWD (Juniper), running software 14.3.10, occasionally stops at traffic lights or stop signs for no apparent reason and does not start moving again until the accelerator is pressed. According to their account, on Pacific Coast Highway the car stopped at a red light; when the light turned green and the car ahead moved off, theirs remained stationary for several seconds until they accelerated. The author also mentions a HW4 Model 3 running the same FSD version, although the text cuts off at that point.…

🔎 Why it matters: No official Tesla confirmation: the case describes a Model Y on 14.3.10 that does not resume moving at a green light until the accelerator is pressed, and the author asks whether others have reported similar behavior.
📈 Upside: Not applicable.
📉 Risk: If it occurs as described, the driver has to press the accelerator manually at a green light; the user reports several seconds of delay on PCH.
