Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and in "Park" mode.
Disconnect the negative terminal of the 12V battery to ensure safety during inspection.

2. Update Software

Reconnect the 12V battery terminal.
Turn on the vehicle and access the touchscreen interface.
Navigate to the "Software" section in settings.
Check for any available updates and follow the prompts to install them if necessary.

3. Inspect and Test Drivetrain Components

Lift the vehicle using a jack and secure it with jack stands.
Inspect the motor mounts for signs of wear and replace if necessary.
Check the connections between the battery, inverter, and motors for any loose or corroded connections.
Tighten any loose bolts and ensure secure electrical connections.

4. Conduct Road Test

With the vehicle back on the ground, perform a test drive.
Monitor for any recurrence of slippage during various acceleration conditions.
If slippage persists, further investigation into the inverter or electric motor may be required.
