Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow the vehicle to cool before inspecting brake components.

Symptoms

•High-pitched noise during acceleration
•Noise persists while driving at different speeds
•Noise is louder when the vehicle is in motion compared to stationary
•Possible vibration felt through the cabin
•Noise may vary with changes in throttle position

Diagnostic Steps

1
Inspect the vehicle's exterior for any visible obstructions or debris around the wheels and undercarriage.
2
Conduct a road test to determine if the noise is linked to specific driving conditions (e.g., acceleration, deceleration, turning).
3
Use an OBD-II scanner to check for any stored error codes related to electrical or mechanical components.
4
Examine the wheel bearings and brake components for wear or damage.
5
Inspect the electric motor and associated components for any signs of malfunction or abnormal wear.
6
Check for loose or damaged panels that could vibrate and create noise under certain conditions.

Solution

1. Preparation

Tools Required: Floor jack, jack stands, wheel chocks, OBD-II scanner, torque wrench, socket set.
Ensure the vehicle is on a level surface and turn off the ignition.

2. Raise the Vehicle

Use the floor jack to lift the front and rear of the vehicle.
Secure with jack stands and place wheel chocks behind the rear wheels.

3. Inspect Brake Components

Remove the wheel to access the brake assembly.
Check brake pads for wear and ensure they are properly seated.
Inspect brake rotors for scoring or damage.
If worn or damaged, replace the brake pads and/or rotors as needed.

4. Check Wheel Bearings

Spin the wheel by hand and listen for any grinding or roughness indicating a bad bearing.
If a bad bearing is detected, replace it by removing the hub assembly and installing a new bearing.

5. Examine Electric Motor Components

Inspect the electric motor for any loose connections or signs of wear.
Tighten any loose connectors and replace any damaged components.
If the motor shows signs of failure, consult service manual for replacement procedures.

6. Reassemble and Test

Reinstall the wheel and torque the lug nuts to manufacturer specifications.
Lower the vehicle and perform a test drive to check if the noise persists.
