Tesla owners who updated to FSD version 14.3.9 report frequent false alerts on their central displays. The system erroneously claims the front FSD camera is dirty and requires service, even when the windshield and camera housing are clean. Tesla has confirmed this is a software bug rather than a hardware failure.
The issue stems from the neural network's visibility detection being overly sensitive in the 14.3.9 update. The system misinterprets minor sunlight glare or standard lighting conditions as surface debris. This bug triggers persistent warnings for drivers to clean the interior of the windshield and visit a service center.
Tesla service departments have begun canceling maintenance appointments related to this specific error. The company advises users to wait for a future software patch. Some owners who previously paid for unnecessary cleaning services at service centers may be eligible for refunds or account credits once a formal resolution process is established.
The company recently released FSD version 14.3.10. While it is currently unclear if this update resolves the bug, Tesla is monitoring user feedback. The false cleaning alerts have primarily been documented by users operating the 14.3.9 version of the software.
