Ignoring a check engine light can turn a minor problem into a major expense, according to a new report by CarMD.

The report found drivers are paying more than ever to fix issues that could have been caught early. A sensor problem left unaddressed, for example, can eventually damage a catalytic converter — a repair that can cost more than $1,500.

Other frequent repairs flagged by the report include:

• Ignition coils and spark plugs, which run close to $500
• Airflow sensor repairs, which can cost more than $300

The report also found the cost of labor is growing, driven in part by newer cars that are more complicated to fix than older models.

Parts prices are another factor drivers need to consider. Supply chain issues or rising parts costs can push repair bills even higher.

When a check engine light appears, getting it checked out quickly can prevent a small issue from growing into a much larger problem.
