Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the battery is disconnected for safety.
Tools Required: Tire pressure gauge, OBD-II scanner, jack and jack stands, basic hand tools (wrenches, sockets).

2. Tire Inspection and Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the PSI of all tires; adjust to manufacturer specifications if necessary.
2. Inspect each tire for uneven wear or damage; replace any that are excessively worn or damaged.
3. If applicable, rotate the tires to ensure even wear.

3. Traction Control System Check

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to read any fault codes related to the traction control system.
3. Clear the codes and take the vehicle for a test drive to see if the issue persists.

4. Drivetrain Inspection

Sub-steps:
1. Visually inspect the driveshaft and axles for any signs of damage or looseness.
2. Check fluid levels in the transmission and differential; top off with manufacturer-recommended fluids if necessary.
3. Tighten or replace any loose or damaged components.

5. Test Drive and Final Adjustments

Sub-steps:
1. Conduct a test drive to assess if the slipping sensation has been resolved.
2. Monitor the vehicle's response to acceleration and check for any warning lights.
3. If the problem persists, further diagnosis may be required to examine the electric motor and control systems.
