Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the 12V battery to prevent any electrical issues during repair.

2. Check Power Steering Fluid

Locate the power steering reservoir: Open the front trunk and find the power steering fluid reservoir.
Inspect fluid level: Remove the cap and check the fluid level against the markings. If low, top up with the recommended fluid type (e.g., Tesla-approved power steering fluid).
Check fluid condition: If the fluid is dark or contaminated, proceed to the next step.

3. Replace Power Steering Fluid (if necessary)

Drain old fluid: Locate the drain plug on the power steering system and use a suitable container to collect the old fluid.
Flush system: Refill the reservoir with new fluid, start the vehicle, and turn the steering wheel from lock to lock to flush out old fluid.
Recheck fluid level: After flushing, ensure the fluid is at the correct level and replace the cap.

4. Inspect Steering Components

Visual inspection: Check the steering rack, tie rods, and other components for signs of wear, damage, or corrosion.
Replace any damaged parts: If any components are found defective, replace them using appropriate OEM parts.

5. Reassemble and Test

Reconnect battery: Once repairs are complete, reconnect the 12V battery.
Test the steering: Start the vehicle and test the steering under various conditions (stationary and in motion) to ensure proper operation.
