What You Should Do
Do not drive the vehicle.
Check brake fluid level and look for leaks.
If fluid is low, top off with DOT 3 or DOT 4 fluid and inspect for leaks.
If no leaks are found, the system likely needs bleeding to remove air.
If the pedal remains soft, the master cylinder may need replacement.
Contact a Tesla service center or qualified technician immediately.
