Solution

1. Preparation

Gather Tools and Materials: Ensure you have an OBD-II scanner, socket set, torque wrench, and any necessary replacement fluids.
Safety Precautions: Disconnect the battery before starting repairs. Allow the engine to cool if it has been running.

2. Fluid Check and Replacement

Check Engine Oil:
- Remove the dipstick, wipe clean, and reinsert to check the oil level.
- If low, add the manufacturer's recommended engine oil until the proper level is reached.
Check Transmission Fluid:
- With the car in park and engine running, remove the transmission dipstick.
- Inspect fluid level and color; if low or burnt, drain and replace the fluid.

3. Inspect and Repair Leaks

Identify Leaks:
- Look under the vehicle and around the engine for signs of oil, coolant, or transmission fluid leaks.
Repair or Replace Components:
- If leaks are found, replace damaged gaskets, seals, or hoses as necessary.
- Tighten any loose connections.

4. Brake Inspection

Check Brake Components:
- Remove the wheel to inspect brake pads, rotors, and calipers for wear or overheating.
- Replace any worn brake pads and ensure calipers are functioning properly.

5. Exhaust System Inspection

Check for Exhaust Leaks:
- Inspect exhaust pipes and joints for any cracks or holes.
- Replace any damaged components or gaskets.
