Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers if applicable.
2. Measure tire pressure and adjust to recommended levels (usually around 42 PSI for Model 3).
3. Use a tread depth gauge to measure the depth; replace tires if below 4/32".
4. If tires are worn, replace with appropriate all-season or performance tires.
Tools Required: Tire pressure gauge, tread depth gauge, jack, jack stands, lug wrench.

2. Traction Control System Check

Sub-steps:
1. Connect an OBD-II scanner to retrieve any error codes.
2. Clear any existing codes and observe if they return after a test drive.
3. If codes indicate a specific sensor issue, replace the faulty sensor (wheel speed sensors or yaw sensors).
Tools Required: OBD-II scanner, socket set.

3. Suspension Inspection and Repair

Sub-steps:
1. Raise the vehicle and support it with jack stands.
2. Inspect control arms, bushings, and struts for signs of wear or damage.
3. Replace any worn components as necessary, ensuring to torque bolts to manufacturer specifications.
4. Check for proper alignment; if misaligned, adjust or replace alignment components.
Tools Required: Socket set, torque wrench, alignment equipment.
