This warning message doesn't mean the brakes are not functioning; instead, the Teslas AEB system has been deactivated for some reason.


Causes of Automatic Emergency Braking Disabled Alert

Some common reasons for the Automatic Emergency Braking (AEB) system to be disabled include software updates, sensor issues, and user settings.


  • Software updates: Tesla vehicles are regularly updated with new software, and during these updates, AEB may be temporarily disabled. This is a normal occurrence, and the system should be re-enabled once the update is complete.

  • Sensor issues: The AEB system relies on sensors and cameras to function correctly. If these sensors or cameras become dirty or obstructed, the system may not be able to function as intended. Cleaning the sensors and cameras or removing any obstruction can fix the problem.

  • User settings: The Tesla vehicle's settings include the option to turn off or adjust the AEB system. If the owner accidentally turns off AEB or changes the settings, it can be easily turned back on by accessing the vehicle's settings; go to Controls > Autopilot > Automatic Emergency Braking and switch it back on.

  • Requires re-calibration: A common reason for an AEB warning message is that the system needs to be re-calibrated. This is common if you’ve recently had a camera, sensor or windshield replaced.


In rare cases, a problem with the AEB system itself may require a trip to a Tesla service center for repair. This could be caused by a malfunction in the system's software or hardware, and it may need to be diagnosed and fixed by a trained technician.


Like any mechanical or electrical parts, they sometimes fail which can cause an AEB failure.
