Top 10 check-engine-light car repairs

No. 10 car repair: Dead battery and charging system

Average repair cost: $100.63

Jumping six spots to No. 10, these problems are occurring more often because more cars have systems that monitor voltage and activate a check-engine light to warn drivers when something is wrong, CarMD says.

High temperatures are a factor in premature aging of these parts, and 2012 was the hottest year on record in the lower 48 states, the National Oceanic and Atmospheric Administration says. The cost to address a battery problem is up 14.6 percent.
