Frequently Asked Questions

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

• Inspect the fuel cap for a loose or damaged seal — a common, simple cause that can trigger an error code.
• Check basic fluids and obvious leaks; low oil or coolant can create engine issues that illuminate the light.
• Look for recent changes — new fuel, rough starts, or odd sounds — and note them for the technician.
• If the light remains on or flashes, stop driving and arrange immediate dealer inspection to avoid compounding damage.

How long does a check engine light service take?

• A standard diagnostic scan typically takes 30–60 minutes to identify stored and pending codes with our dealer-grade tools.
• Minor repairs, like tightening a fuel cap or replacing a sensor, are often same-day jobs; more complex issues may require parts and overnight work.
• Scheduling through our service scheduler shortens wait time; authorized service ensures warranty compliance and documented work history.
• Because we use factory-trained technicians and genuine parts, you often save time and money over independent shops thanks to accurate first-time fixes.
