Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electric shock during servicing.

2. Update Software

Reconnect the vehicle to Wi-Fi.
Access the settings menu on the touchscreen and navigate to software updates.
Download and install any available updates, following on-screen instructions.

3. Inspect Battery and Connections

Reconnect the battery terminal.
Use a multimeter to check the battery voltage; it should read between 12.6V to 12.8V when fully charged.
Inspect battery connections for corrosion or looseness and clean or tighten as necessary.

4. Throttle Inspection

Remove any panels necessary to access the throttle body.
Check the throttle linkage for proper movement; it should not be sticky or obstructed.
Lubricate moving parts if needed and ensure the accelerator pedal is functioning smoothly.

5. Electric Motor Inspection

If overheating is suspected, allow the vehicle to cool down before proceeding.
Remove the cover from the electric motor and visually inspect for any signs of damage or debris.
Check electrical connections to the motor for tightness and signs of wear.

6. Test Drive and Final Checks

Reassemble any components removed during the inspection.
Reconnect the negative battery terminal.
Conduct a test drive to confirm the vehicle's acceleration performance has returned to normal.
