The CarMD® Vehicle Health Index™ reports on the most common check engine light-related problems, repairs and associated costs. Published annually since 2011, this Index provides year-over-year car repair data.

The check engine light comes on when a vehicle’s computer detects a problem that affects emissions or drivetrain issues. If ignored, it will hurt the environment, the car’s fuel economy and lead to more problems down the road.

Check Engine Light Insight

Don’t panic when the check engine light comes on, but get it diagnosed ASAP. It can be as simple as a loose gas cap. But a flashing check engine light can indicate a more serious problem such as an engine misfire that needs immediate attention from roadside assistance. If your car’s check engine light is on, it will keep a vehicle from passing its state emissions test and negatively impact fuel economy if ignored.

CarMD Garage is a free online resource that drivers can use to check for upcoming maintenance, technical service bulletins and common check engine problems by year, make, model and mileage.
