Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and in "Park" mode.
Disconnect the vehicle from any charging source.

2. Tire Inspection and Replacement

Inspect tires:
- Check for uneven wear, cracks, or damage.
- Measure tread depth; replace tires if tread is below recommended levels (usually 2/32 inches).
Replace tires if necessary:
- Use a jack to lift the vehicle, ensuring it is secure.
- Remove wheel nuts with a socket wrench.
- Replace the tire with a new one or rotate tires if uneven wear is found.
- Tighten wheel nuts in a star pattern to the manufacturer's torque specification (typically 80-100 ft-lbs).

3. Suspension Components Check

Inspect suspension:
- Check for worn bushings, struts, or shocks that may affect handling.
- Replace any damaged components using the appropriate tools (wrenches, sockets).

4. Software Update

Check for software updates:
- Connect the vehicle to Wi-Fi.
- Navigate to the software update section in the vehicle’s touchscreen menu.
- Install any available updates and ensure the traction control software is current.
