Tesla’s latest full self-driving (FSD) software update has hit an unexpected speed bump with a false warning.
The company’s FSD v14.3.9 update is reportedly warning owners that their cameras have poor visibility — even when the lenses and windshield are clean.

The software glitch has prompted some Tesla owners to schedule service appointments unnecessarily.
Tesla has acknowledged the issue and is reportedly cancelling appointments triggered by the false warning, with a fix expected in a future software update.
Tesla owners see a “poor camera visibility” warning
Owners who installed FSD v14.3.9 began seeing an alarming message on their vehicles’ centre displays: “Poor camera visibility detected. Interior windshield residue cleaning is required.”
So, what was the problem? In many cases, there was no residue or obstruction to clean.
Reports indicate that the warning can appear when the vehicle is exposed to bright sunlight, glare, or challenging lighting conditions.
The FSD system appears to interpret normal optical conditions as a potentially obstructed forward-facing camera.
Tesla owner @CARN0N shared a screenshot of Tesla Support confirming that the warning was caused by a software issue.
Other Tesla owners have reported similar experiences on Reddit, saying the warning appeared despite having clean cameras.
Tesla is cancelling unnecessary service appointments
Tesla appears to be aware that the software is sending owners towards service centres unnecessarily.
According to reports, Tesla Support has been proactively cancelling appointments that were booked because of the camera-visibility warning.
For owners who receive the alert, the advice is straightforward: Don’t immediately book a service appointment if the cameras and windshield are visibly clean.
Owners who already paid for a cleaning or inspection because of the warning may want to contact Tesla Support to ask about a refund.
What caused the Tesla FSD camera bug?
The issue affects FSD v14.3.9, associated with software builds 2026.27.5 and 2026.27.6, which began rolling out around September 12.
The update also introduced Automatic Collision Evasion for HW4-equipped Tesla vehicles, allowing FSD to take control of the vehicle in certain situations to help avoid an imminent collision.
A subsequent build, v14.3.10, is expected to address the camera alerts.
However, its release notes have reportedly remained identical to those of v14.3.9, implying the exact changes behind the scenes have not been publicly confirmed.
A small bug highlights a bigger FSD challenge
The false camera warning may be an inconvenience rather than a serious safety issue, but it highlights one of the biggest challenges facing camera-based driver-assistance systems.
Tesla’s vision-based approach needs to distinguish between genuine camera degradation caused by dust, fog, glare, or residue and normal changes in lighting.
If the system becomes too sensitive, it risks generating false warnings. If it is not sensitive enough, it could fail to recognise a genuinely compromised camera.
That balance becomes increasingly important as Tesla continues developing FSD towards its more autonomous operation.

For now, Tesla owners affected by the v14.3.9 warning should check their cameras and windshield first and avoid unnecessary service visits if everything is clean. A software fix appears to be on the way.
