3. Brake Wear

• Symptoms: Visible wear on seats, steering wheel, or dashboard.
• Solution: Use high-quality leather conditioners and cleaning products. Damaged materials may require professional repair or replacement.

6. Excessive Tire Wear

• Issue: The Q70’s alignment and suspension design can cause tires to wear unevenly or prematurely.
• Symptoms: Uneven tread wear, vibration while driving, or reduced handling performance.
• Solution: Regularly rotate tires, check alignment, and replace tires when necessary.

7. Fuel Economy Complaints

• Issue: Some owners feel the fuel economy, especially with the V8 engine, is lower than expected.

8. Power Steering System Issues

• Symptoms: Reduced fuel economy, warning lights on the dashboard, or decreased hybrid assist.
• Solution: Inspect the hybrid battery system and replace or repair components as needed.

10. Engine Oil Consumption (V8 Models)

• Symptoms: Frequent need to top off oil or low oil warning light.
