Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, floor jack, jack stands, multimeter, inspection mirror.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow engine to cool before inspecting.

2. Address Oil Leaks

Locate Leaks: Use a flashlight and inspection mirror to identify any visible oil leaks around the engine and transmission.
Replace Seals/Gaskets: If leaks are found, replace any damaged seals or gaskets as necessary (e.g., valve cover gasket, oil pan gasket).
Top Off Oil: Ensure engine oil is at the proper level. Use the manufacturer-recommended oil type.

3. Brake Inspection and Repair

Remove Wheel: Use a floor jack to raise the vehicle and secure it with jack stands. Remove the wheel to access brake components.
Inspect Brake Pads and Rotors: Check for excessive wear on the brake pads and ensure rotors are not warped. Replace if necessary.
Check Caliper Function: Test caliper movement. If calipers are sticking, clean or replace them.

4. Electrical Inspection

Inspect Wiring: Look for any frayed or damaged wires in the engine bay and undercarriage.
Repair Damaged Wiring: Use electrical tape or connectors to repair any damaged wiring. Replace any burnt components.

5. Exhaust System Check

Inspect Exhaust Components: Examine exhaust pipes and catalytic converter for any signs of burning or melting.
Replace Damaged Parts: If damage is found, replace the affected parts as needed.
