Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the 12V battery to prevent any electrical issues during inspection.

2. Inspect the Drivetrain

Tools Required: Socket set, torque wrench
Remove the underbody shield (if applicable) to access the drivetrain components.
Visually inspect the electric motor and associated mounts for cracks or looseness.
Tighten any loose bolts to manufacturer specifications.

3. Check the Electric Motor

Tools Required: Torque wrench
If the motor shows signs of wear, it may need to be replaced. Consult the service manual for the correct procedure.
Ensure all wiring harnesses connected to the motor are secure and free from damage.

4. Examine Wheel and Tire Assembly

Tools Required: Tire pressure gauge, jack, jack stands
Raise the vehicle using a jack and secure it with jack stands.
Inspect the tires for uneven wear or damage that could cause noise during acceleration.
Rotate or replace tires if necessary.

5. Reassemble and Test

Reinstall any removed components and ensure all fasteners are torqued to specifications.
Reconnect the 12V battery.
Conduct a test drive to verify that the whirring noise has been resolved.
