Tesla has released a new guided tool inside its vehicle software to help technicians clean front-facing cameras. The feature fixes a hazy film that builds up inside the windshield and blocks the view for the Full Self-Driving and Autopilot systems. Now, service manuals list the update as part of software version 2026.20, and it applies to the Model 3, Model Y, recent Model S (2021+) and Model X vehicles (2021+), and the Cybertruck.
The problem originates from interior car parts, and over time, plastic pieces release gases that form a thin layer on the glass right in front of the camera housing. Drivers often cannot see this haze under normal lighting, but eventually the vehicle system detects the poor visibility and warns the driver to schedule a service visit.
The four-step repair process
The new Service Mode panel gives workers a clear four-step process to fix the problem directly on the touchscreen. To begin, technicians must clean the glass following a specific manual, and they remove the plastic trim to use approved glass cleaner with lint-free cloths. Next, they check a live video feed on the screen to verify the glass is clear. Workers can easily switch between the main and wide camera views to check their work before moving to the next step.
After that, the technician records the cleaning in the vehicle’s history file using the same screen. Then, they perform a system reset for the Driver Assistance System (DAS), and system alerts clear out once the restart finishes successfully.
Repair costs and warnings
In the past, Tesla offered to clean the cameras for free when the warning first appeared in late 2025. Today, service centers charge between 50 and 89 dollars for the job, depending on the location and vehicle model. The company advises owners not to clean the inside glass themselves, as regular household cleaners can damage special coatings on the windshield and make the visibility worse.
Beyond that, factory documents state workers must do the cleaning indoors or in the shade. Sun glare and open skies can interfere with the camera calibration process, so workers keep the cars under a roof. In fact, this update brings the entire maintenance routine directly into the car’s touchscreen, and industry watchers say the change helps technicians finish the repair faster.
