Solution

1. Preparation

Ensure the vehicle is parked in a safe area with adequate ventilation.
Disconnect the high-voltage battery if necessary to prevent electrical hazards.

2. Inspect and Clean the Brake System

Sub-steps:
1. Remove the wheel covers or lug nuts using a socket set.
2. Remove the wheel to access the brake assembly.
3. Inspect the brake pads for wear; replace if they appear burnt or excessively worn.
4. Clean the brake calipers and rotor surfaces with brake cleaner.
5. Reassemble the wheel and torque lug nuts to the manufacturer's specified value (typically 100-120 ft-lbs).

3. Inspect the High-Voltage Battery

Sub-steps:
1. Check for any signs of damage to the battery casing and wiring.
2. If damage is present, consult a certified Tesla technician for battery replacement or repair.
3. Use a multimeter to ensure battery voltage is within normal operating range (typically around 350-400V).

4. Electrical System Check

Sub-steps:
1. Inspect all visible wiring for fraying or burns.
2. Tighten any loose connections to ensure proper electrical contact.
3. Inspect the power inverter for any signs of overheating or failure.

5. Test Drive

Sub-steps:
1. Conduct a test drive to observe any changes in performance or any reoccurrence of the burning smell.
2. Monitor any warning lights on the dashboard during the test drive.
