Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure using a tire pressure gauge; inflate as necessary to manufacturer specifications.
2. Inspect tire tread depth using a tread depth gauge; replace tires if tread is below 2/32 inches.
3. If tires are worn unevenly, consider a four-wheel alignment.

Tools Required: Tire pressure gauge, tread depth gauge, jack, jack stands, lug wrench.

2. Suspension Inspection and Repair

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect struts and shocks for leaks or damage; replace any faulty components.
3. Check control arms and bushings for wear; replace if cracked or worn.

Tools Required: Socket set, torque wrench, pry bar.

3. Electronic Stability Control (ESC) System Check

Sub-steps:
1. Use an OBD-II scanner to check for any fault codes related to the ESC system.
2. Clear any fault codes and perform a road test to see if the issue persists.
3. If warning lights reappear, consult the vehicle's service manual for further diagnostics.

Tools Required: OBD-II scanner.

4. Alignment Adjustment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Request a complete four-wheel alignment and adjust as necessary to manufacturer specifications.

Tools Required: None (performed at the alignment shop).
