Tesla FSD v14.3.9 Bug Triggers False Camera Cleaning Alerts

Tesla has acknowledged a software bug in FSD v14.3.9 that falsely warns of dirty front-facing cameras and demands service visits even when the windshield is clean. The company is proactively canceling scheduled cleaning appointments and advising owners not to book service; a fix is expected in a future update.

• The bug appeared after FSD v14.3.9 rolled out with Automatic Collision Evasion
• The vision encoder misreads sun glare as a dirty camera needing cleaning
• Tesla Service is proactively canceling scheduled cleaning visits
• It is unclear whether FSD v14.3.10 fixes the issue; release notes are identical
