Are Tesla Cameras Dangerous in the Rain?

Tesla has confirmed working on a “comprehensive cleaning solution” for the embedded cameras of its vehicles.

This statement was made on X (formerly Twitter) viaTesla AI’s official account, in response to a post highlighting how easily the Cybertruck’s rear camera can be obstructed by dirt, especially in wet conditions or off-road use. However, Tesla has not specified whether this solution would be exclusive to the Cybertruck or extended to other models in its lineup. It also remains uncertain if existing vehicles could benefit from it via a retroactive update.

Tesla vehicles rely heavily on cameras for their Autopilot and Full Self-Driving (FSD) features, utilizing an array of external cameras to provide a 360-degree view of the vehicle’s surroundings. While this approach eliminates the need for technologies like radar or LiDAR, it presents a major challenge when these cameras are covered with dirt, snow, or mud.

Winter conditions particularly exacerbate this issue. Snow, mud, and ice can accumulate on the lenses, especially in regions where road salt is commonly used. Outside of winter, dust, mud, and rain streaks can reduce visibility, compromising the accuracy of FSD features and forcing drivers to manually clean the cameras.

If one or more cameras are obstructed, the system may not function optimally, leading to decreased performance or even deactivation of FSD features. While Tesla has not detailed the planned cleaning solution, several options are conceivable, such as automated spray systems using windshield washer fluid, hydrophobic coatings to repel water and dirt, or compressed air to dislodge dust and moisture.

This initiative is promising, but remains uncertain in terms of implementation timeline and availability for existing models. The Cybertruck has already been equipped with a cleaner for its front camera, but not for the rear camera, which is more exposed. An efficient and universal solution would be particularly welcome, especially for drivers in regions with harsh winters.
