Solution

1. Preparation

Tools Required: OBD-II scanner, jack, jack stands, tire pressure gauge, torque wrench.
Safety Warnings: Ensure the vehicle is in "Park" and turned off before beginning work. Use jack stands for safety when lifting the vehicle.

2. Tire Pressure Adjustment

Check the tire pressure using a tire pressure gauge.
Inflate or deflate tires to the recommended PSI as stated on the door jamb sticker.
Verify all tires have even tread wear; replace if necessary.

3. Brake System Inspection

Remove the wheel to access the brake assembly.
Inspect brake calipers for proper function; ensure they are not sticking.
Check brake pads for wear; replace if worn below specification.
Reinstall the wheel and torque to manufacturer specifications.

4. Suspension Assessment

Inspect shocks and struts for any leaks or physical damage.
Check for worn bushings or ball joints that could affect vehicle handling.
Replace any faulty components as needed.

5. Drivetrain Check

Listen for unusual sounds from the electric motor during low-speed maneuvers.
Inspect the drivetrain components for any signs of wear or misalignment.
Address any issues found during inspection; this may require professional service if components are damaged.
