Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if working on electrical components.

2. Inspect Tires

Remove wheel covers if applicable.
Inspect each tire for uneven wear, bulges, or foreign objects.
Replace any damaged tires with new ones, ensuring proper tire pressure.

3. Check Brake System

Remove the wheels to access the brake components.
Inspect brake pads and rotors for signs of overheating or wear.
- Sub-step: Replace pads if worn beyond manufacturer's specifications.
- Sub-step: Resurface or replace rotors if they show signs of warping or scoring.
Ensure that the calipers are not sticking; lubricate or replace as necessary.

4. Examine Underbody Components

Check for any plastic or rubber components that may be in contact with hot surfaces (e.g., exhaust).
Replace any melted or damaged components.
Clear any debris that might be lodged in the undercarriage.

5. Test Driving

Reassemble all components and ensure everything is secured.
Take the vehicle for a test drive, monitoring for the smell.
Check if the problem persists after repairs.
