Tesla FSD v14.3.9 bug falsely warns of dirty cameras, triggers unnecessary service visits
The latest Full Self-Driving update v14.3.9 incorrectly alerts owners that their cameras are dirty, prompting service appointments that Tesla is now canceling.
Tesla’s recent Full Self-Driving software release, version v14.3.9, has been issuing false warnings to drivers that the vehicle’s front‑facing cameras need cleaning. The alerts appear even when the lenses are spotless.
Owners receiving the notifications were directed to schedule service appointments at Tesla service centers, where technicians were asked to clean the cameras. Upon inspection, the cameras were found to be clean and functioning normally.
Tesla has acknowledged the issue as a software bug introduced in the v14.3.9 update and confirmed that all service appointments generated by the false alerts are being cancelled. The company is actively working on a fix.
Engineers are preparing a patch that will be included in an upcoming Full Self-Driving release. While Tesla has not disclosed an exact rollout date, it expects the corrective update to arrive in the near future.
The episode highlights the importance of robust validation for driver‑assistance systems, especially as autonomous features expand globally. For markets like Uzbekistan, where pilot programs for self‑driving vehicles are being considered, such glitches reinforce the need for thorough software testing before widespread deployment.
