CarMD.com Corp. has released its 2018 CarMD Vehicle Health Index Make and Model Reliability Rankings..
Published annually since 2011, this Index analyzes check engine repairs and costs to rank the 10 brands and 100 vehicles least likely to have a check engine light on; 10 makes and 100 vehicles with the lowest average repair costs; and top three vehicles by category. CarMD analyzed data from over 5.6 million in-use vehicles, model year 1996 to 2018, reporting check engine health from Oct. 1, 2017 – Sept. 30, 2018.
“The CarMD Vehicle Health Index Make and Model Reliability Ranking is the only report that statistically measures check engine failures and repair costs,” says David Rich, CarMD’s technical director. “Understanding which makes and models have which kinds of problems, how frequently they occur and what those repairs cost can be useful to vehicle owners, used car buyers, as well as repair professionals looking to increase their knowledge of trends within the industry.”
10 Most Reliable Brands
At least 10% of the cars and trucks on the road in the U.S. have a check engine light on at any given time, and a pilot test of the new CarMD Pro Scan repair shop solution found that as many as 25% of vehicles brought to the repair shop have a check engine light on. Because it is likely that every vehicle owner will eventually have to address a check engine light, CarMD studied data from more than 5.6 million vehicles from many sources to help identify the makes least likely to need check engine repairs.
To rank these makes, CarMD developed a formula that accounts for those with the lowest percentage of repair incidents per percentage of vehicle population. Based on this data, an Index frequency score is assigned. The lower the score the higher the vehicle make ranking.
CarMD found that over the past year, Toyota ranked no. 1 as the brand least likelyto have a check engine light on. Toyota is followed by Acura (no. 2) and Hyundai (no. 3).
