Solution

1. Preparation

Gather Tools: OBD-II scanner, tire pressure gauge, jack, jack stands, lug wrench.
Safety Precautions: Park the vehicle on a flat surface, engage the parking brake, and wear safety gloves.

2. Tire Inspection and Adjustment

Check Tire Pressure:
- Use the tire pressure gauge to measure the pressure in each tire.
- Inflate tires to the specified pressure if necessary.
Inspect Tire Condition:
- Look for uneven wear or visible damage.
- Replace any tires that are excessively worn or damaged.

3. Brake System Inspection

Remove Wheel:
- Use a lug wrench to loosen and remove the lug nuts.
- Use a jack to lift the vehicle and secure it with jack stands.
Inspect Brake Components:
- Check brake pads for wear and ensure they are not stuck in the caliper.
- Verify that calipers are functioning properly and not applying pressure when released.
Reassemble Wheel:
- Reattach the wheel, hand-tighten lug nuts, lower the vehicle, and torque the lug nuts to the manufacturer's specifications.

4. Drivetrain Evaluation

Inspect Drivetrain Components:
- Examine the electric motor and associated components visually for any signs of damage or obstruction.
- Check for any unusual noises when the vehicle is in drive and at rest.
Software Update:
- Connect the vehicle to Wi-Fi and check for software updates via the vehicle’s touch screen.
- Follow prompts to install any available updates.
