      2. Ensure the vehicle is connected to Wi-Fi during the process.
      3. Allow the update to complete fully before testing the vehicle.
3. Drive Unit Inspection
  • Inspect the drive unit:
    1. Raise the vehicle using a hydraulic lift or jack stands.
    2. Visually check for any fluid leaks around the drive unit.
    3. Look for any signs of physical damage or unusual wear on the motor mounts and connections.
    4. If damage is found, consult Tesla service for necessary repairs.
