Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during inspection.
Allow the vehicle to cool if the engine has been running.

2. Check Engine Oil

Remove the engine oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add manufacturer-recommended oil to the correct level.
If dirty or burnt, perform an oil change:
- Drain the old oil and replace with new oil.
- Replace the oil filter.

3. Inspect and Replace Brake Components

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for wear; if they are less than 3mm thick, replace them.
Check the brake rotors for warping or damage; replace if necessary.
Reassemble the brake components and wheels, ensuring proper torque specifications (typically 100-150 ft-lbs for lug nuts).

4. Inspect Electrical Components

Check for any frayed or damaged wiring harnesses near the engine and under the dashboard.
If any wires are damaged, repair or replace them as necessary.
Ensure all connectors are secure and free from corrosion.
