Repair Instructions

Perform Software Update
- If an update is available, follow the on-screen instructions to install it.
- Restart the vehicle if prompted.
Adjust Regenerative Braking Settings
- Set regenerative braking to "Low" temporarily to see if it alleviates the issue.
- Monitor performance over several drives.
Clear Fault Codes
- If fault codes were detected, clear them using the OBD-II scanner.
- Test drive the vehicle to see if codes reappear.
Battery Management Check
- If the battery is fully charged and still experiencing issues, consider discharging to a lower level (between 20-80%).
- If battery temperature exceeds normal limits, allow it to cool down before driving.
Brake System Inspection and Maintenance
- If worn brake components are found, replace them accordingly.
- Ensure all brake lines and fluid levels are in optimal condition.
Contact Tesla Support
- If the problem persists after all diagnostics and repairs, contact Tesla customer support or schedule a service appointment for further evaluation.
