Don’t panic, but don’t ignore it either
Check engine light on?
If your check engine light comes on, it could be due to something as simple as a loose gas cap or something as serious as a poorly running engine. Either way, you should get it checked out as soon as possible by a qualified auto shop.
Driving long distances with the check engine light on could result in larger problems and more expense down the road.
The safest thing route is to schedule a free inspection so we get you back on the road with a safe vehicle sooner rather than later.

Free code retrieval
Our free check engine light code retrieval service will identify why your check engine light is on quickly and accurately.
When your check engine light turns on, a fault code (OBD II) is registered in your vehicle’s diagnostic system computer detailing the nature of the problem. This fault code is stored and can only be retrieved with specialized equipment that can communicate with your vehicle’s onboard computer.
We use that equipment to pull the code from your vehicle’s computer to determine a course of action to get you back on the road as soon as possible.
