"CarMD has released its 2016 Vehicle Health Index, documenting the top most common check engine repairs in 2015. This year’s Index statistically analyzes 1,019,904 repairs that were uploaded to the CarMD diagnostic database from January 1, 2015 to December 31, 2015. All 50 U.S. states, including the District of Columbia, are represented in the Index.

CarMD also highlighted that vehicle age affects the type, cost and percentage of check engine light repair incidents with model year 2006 vehicles accounting for more than 10 percent of cars needing repairs last year. They also had the highest average repair cost at $399. Brand new 2016 model year vehicles accounted for only 0.01 percent of repairs, with an average cost of $205, which was usually covered under warranty."
