Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery for safety.

2. Inspect and Clean Electrical Connections

Remove any covers or panels to access the battery and wiring.
Inspect all wiring for signs of damage, corrosion, or melting.
Clean any corroded connections using a wire brush and electrical cleaner.

3. Inspect and Replace Brake Components

Lift the vehicle on jack stands and remove the wheels.
Inspect brake pads for wear; replace if less than 3mm thick or if glazed.
Examine rotors for scoring or heat marks; replace if necessary.
Reassemble the brake components following torque specifications for caliper bolts (typically 25-35 lb-ft).

4. Check and Repair Battery Pack (if applicable)

Inspect the battery pack for any signs of damage or overheating.
Tighten any loose connections and check for corrosion.
If overheating is detected, consult a Tesla specialist for further diagnosis.

5. Reassemble and Test

Reconnect the battery and all covers/panels removed during inspection.
Start the vehicle and allow it to idle for a few minutes, then drive at low speed to check for any further smells or warnings.
