There are probably not many people who don’t know what their “Check Engine” lights look like. This little mystery light has probably come on in almost every car ever made at one point or another. And the funny thing is that many mechanics are just as stumped as you are when you take your car in to see why the light came on in the first place.

Of course, there are the obvious reasons: you let the engine run too low on oil, there’s a short in the dashboard lights or any one of many other reasons. And many car owners experience the horror story of paying hundreds of dollars to fix the problem only to have the light come back on within hours of leaving the service station.

If you check your dash, though, you’ll notice that the warning lights are color-coded. The “Check Engine” light is yellow, which means that there’s nothing seriously wrong yet. But it’s in your best interest to get the car checked as soon as possible. The red lights are the ones that mean something serious is wrong and you need to pull over right away and turn off the car. By this time, though, the damage is probably done already.

But if you have a certified Ford, you don’t have to worry about any costs associated with the “Check Engine” light. As long as you keep up with the vehicle’s preventative maintenance such as oil changes, tune ups and other services, you won’t have out-of-pocket costs when the yellow light comes on. Think of how much peace of mind that brings to car ownership and visit a Ford dealer today.
