This 2017 Index ranks brands and vehicles for frequency of check engine light problems and average cost of repairs for a large array of makes and models. It ranks the 10 brands with the lowest repair incidents/lowest average car repair costs, 100 vehicles by year, make and model with the fewest repair incidents/lowest average repair costs, and top three vehicles by category. Historical rankings are not necessarily indicative of future vehicle reliability.
To achieve this unmatched level of accuracy, we have analyzed the check engine health of more than 4.2 million models that span from 1996 to 2017. Each data point was administered on real in-use vehicles reporting check engine health between Oct. 1, 2016 and Sept. 30, 2017. Consumers, used car buyers and fleet managers have a goal to minimize vehicle upkeep, while OE manufacturers and aftermarket providers look to increase their knowledge of trends within the industry. This Index offers insight to improve on what every consumer and business cares about – the bottom line.
