Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the high-voltage battery before inspecting electric components.

2. Inspect and Replace Brake Components

Tools Required: Jack and jack stands, socket set, torque wrench, brake cleaner
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect the brake pads for wear; if they are worn down to the metal, replace them.
4. Check the brake rotor for scoring or overheating signs and replace if necessary.
5. Reassemble the wheel and lower the vehicle.

3. Inspect Electric Motor and Wiring

Tools Required: Multimeter, torque wrench
Sub-steps:
1. Remove any covers or shields protecting the electric motor and wiring.
2. Visually inspect for any signs of wear, fraying, or melting in the wiring.
3. Use a multimeter to check the resistance of the motor windings to ensure they are within specifications.
4. Tighten any loose connections to ensure proper electrical contact.

4. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack and jack stands
Sub-steps:
1. Check each tire's pressure and adjust to manufacturer's specifications.
2. Inspect tires for uneven wear, bulges, or damage that could lead to overheating.
3. Replace any damaged tires and ensure they are properly balanced and aligned.
