Solution

1. Preparation

Tools Required: Jack and jack stands, OBD-II scanner, flashlight, basic hand tools (socket set, wrenches).
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect Underbody and Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the exhaust system for any loose hangers or cracks, which could cause popping noises.
3. Check the suspension components (control arms, struts, etc.) for any signs of damage or wear.
4. Look for any foreign objects lodged in the undercarriage.

3. Electrical System Check

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to check for any fault codes related to the electric motor or drivetrain.
3. Clear any codes found and take the vehicle for another test drive to see if the popping noise returns.

4. Drivetrain Inspection

Sub-steps:
1. Inspect the electric motor mount for any signs of wear or damage.
2. Check the drive shaft and associated components for looseness or unusual movement.
3. If necessary, consult vehicle service manual for torque specifications and service intervals.
