For manual handles:
- Check for dirt, ice, or debris causing obstructions.
- Clean and lubricate the moving parts for smoother operation.
Reset the System (for Automatic Handles)
To reset electronic components:
- Press and hold the brake pedal and the “Park” button for 10 seconds.
- Check for software updates through the car’s touchscreen, as Tesla often releases fixes for door handle issues.
Replace the Handle
If the handle is broken or damaged:
- Purchase a replacement from Tesla or a third-party supplier.
