Solution

1. Preparation

Tools Required: Tesla mobile app, OBD-II scanner (if applicable), tire pressure gauge.
Remove any unnecessary weight from the vehicle, such as heavy cargo or equipment.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all tires.
Inflate the tires to the recommended pressure listed on the driver's door jamb sticker.
Recheck tire pressures after inflation to ensure they are correct.

3. Battery Management System Reset

Power off the vehicle by putting it in Park and exiting the vehicle.
Wait for at least 5 minutes to ensure all systems are completely powered down.
Re-enter the vehicle and power it back on to reset the battery management system.

4. Software Update

Check for software updates via the Tesla touchscreen under 'Software' settings.
If an update is available, connect to Wi-Fi and initiate the update process.
Allow the vehicle to complete the update and reboot.

5. Professional Inspection

If the problem persists, schedule an appointment with a Tesla Service Center.
Have them perform a detailed diagnostic check on the battery and powertrain systems.
Discuss any potential battery pack replacements or repairs if degradation is detected.
