Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Check the gas cap: a loose or damaged cap is a common and simple cause that can trigger the light.
• Look for obvious signs: low oil, dashboard warnings, or unusual sounds or smells before driving further.
• If the light is flashing, stop driving and contact us — a flashing light often signals a serious misfire.
• Document when it started and any recent maintenance; that history helps our factory-trained technicians at Park Place Motorcars Fort Worth diagnose faster.
• Remember: repairs covered under warranty must be completed at a certified dealership to retain coverage and ensure long-term savings.

• Initial diagnostic scan typically takes 30–90 minutes depending on symptoms and access to stored codes.
