In its latest state ranking of check engine light-related car repair costs, CarMD finds vehicle owners in Connecticut paid the most ($418) and Maine the least ($349) for repairs during calendar year 2021.
Rounding out the five most affordable states for car repair after Maine were Ohio, Michigan, Iowa and Wisconsin – all located in the Midwest. After Connecticut, the states/districts needing the most expensive car repairs were Colorado, California, District of Columbia and Georgia. The most frequently diagnosed repair in all five of the states with the highest average repair costs was “replace catalytic converter.” Costly parts that contain precious metals, catalytic converters do not typically fail unless maintenance and other repairs such as a faulty oxygen sensor or ignition coil are ignored, or a vehicle has high mileage.
“Several factors contribute to a state’s average repair costs, including vehicle year, make and model, the repair difficulty and associated parts cost,” said David Rich, technical director, CarMD. “It makes sense that as people hold onto their vehicles longer than ever before, cars and trucks start to outlast their parts and need more costly repairs. Staying current on maintenance can help vehicle owners reduce surprise car repair bills, while fixing check engine light problems quickly can improve fuel economy and reduce the likelihood of additional repairs down the road.”
