Ensure the vehicle is parked on a flat surface with the engine cool.
Disconnect the battery to avoid electrical issues.

2. Inspect the Engine Bay

Remove the engine cover (if applicable) using a socket set.
Visually inspect the serpentine belt for cracks, fraying, or signs of melting.
Check all pulleys for proper alignment and any signs of burning or friction.

3. Check the Brake System

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the brake components.
Inspect brake pads and rotors for overheating signs; replace any damaged components.

4. Inspect Tires

Remove the tires for a thorough inspection if burning smell persists.
Check for uneven wear, bulges, or foreign objects stuck in the tread that could cause friction.
Replace any damaged tires as necessary.

5. Address Electrical Issues
