Frequently Asked Questions

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

• Start simple: check the gas cap for tightness and for visible damage; a loose or damaged cap is a common trigger on the 2011 Acura TL and an easy fix.
• Verify basic fluids—engine oil and coolant—so you can rule out low-fluid conditions that may worsen the issue.
• Note vehicle behavior: drivability issues, strange noises, or smells help technicians prioritize diagnostic steps and avoid unnecessary repairs.
• If the light persists after simple checks, bring your 2011 Acura TL to Nalley Acura so our factory-trained technicians can run a complete OEM diagnostic and protect your warranty.
