why does my Acura MDX YF3 (2022-Present) pull to one side when driving

Symptoms

• Vehicle pulls to one side (left or right)
• Uneven tire wear
• Steering wheel may be off-center when driving straight
• Vibration in the steering wheel
• Check tire pressure warning light (if applicable)

Diagnostic Steps

1. Visual Inspection of Tires:

   • Check for uneven wear patterns on the tires. Look for bald spots, cupping, or excessive wear on one side.
   • Ensure all four tires are inflated to the manufacturer’s recommended pressure (check the driver’s door jamb for specifications).

2. Check Wheel Alignment:

   • Use an alignment tool or visit a professional alignment shop to assess the alignment angles (camber, caster, toe).

3. Inspect Suspension Components:

   • Look for any signs of damage or excessive wear on suspension components (control arms, bushings, tie rods). Inspect for any loose or broken parts.

4. Test Drive:

   • Take the vehicle for a test drive on a flat, straight road to confirm the pull. Note if the pull is consistent at different speeds.

5. Scan for Error Codes:

   • Use an OBD-II scanner to check for any error codes that may indicate issues with the vehicle's stability control system or other related components.
