Solution

1. Preparation

Ensure the vehicle is in Park mode.
Disconnect the negative terminal of the 12V battery to prevent electrical shorts.
Gather necessary tools and parts.

2. Software Update

Reconnect the vehicle to Wi-Fi.
Access the vehicle's software update menu on the touchscreen.
Follow on-screen prompts to download and install any available updates.
Restart the vehicle after installation to ensure changes take effect.

3. Inspect Gear Selector

Remove the console cover using a trim removal tool to access the gear selector mechanism.
Inspect the gear selector for any signs of wear or damage.
Check the wiring harness and connectors for corrosion or loose connections.
If damaged, replace the gear selector assembly.

4. Battery Inspection

Reconnect the negative terminal of the 12V battery.
Use a multimeter to measure the voltage of the 12V battery; it should be above 12.4 volts.
If the battery is weak, replace it with a new one of the same specifications.

5. Component Testing

Reconnect the OBD-II scanner and clear any fault codes.
Test drive the vehicle to see if the issue persists.
If the issue remains, consider checking the electric motor and transmission components for faults.
