Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Tools Required: OBD-II scanner, socket set, jack stands, multimeter, brake fluid, engine oil, and cleaning rags.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspecting components.

2. Addressing Oil Leaks

Check the engine oil level and top off if low.
Inspect for oil leaks around the oil pan, valve covers, and gaskets.
Replace any damaged gaskets or seals identified as leaking.
Clean any spilled oil to prevent further burning smells.

3. Brake System Inspection

Remove the wheels to access brake components.
Inspect brake pads and rotors for excessive wear or overheating.
Replace worn brake pads and resurface or replace rotors as necessary.
Bleed the brake system and refill with fresh brake fluid if overheating is suspected.

4. Electrical Inspection

Visually inspect wiring harnesses for frayed or damaged wires.
Repair or replace any damaged wiring as needed.
Check fuses and relays related to the components that may be malfunctioning.

5. Addressing Transmission Issues

Check the transmission fluid level; add fluid if low.
Inspect for any leaks around the transmission pan or cooler lines.
If fluid appears burnt or smells burnt, consider a transmission fluid change.
