A flashing check engine light in a 2010 Subaru Legacy signals an active misfire or condition that can damage the catalytic converter if driven long-term.

Customers appreciate our upfront estimates and the way we explain short- and long-term savings—fixing a misfire promptly avoids replacement of expensive components later.

Common check engine codes for a 2010 Subaru Legacy include P0420 (catalyst system efficiency low), P0171/P0174 (lean condition), P0135/P0161 (oxygen sensor heater circuit), and misfire codes like P0300-P0304. Ignoring these codes can escalate costs: a P0420 left unaddressed may lead to expensive catalytic converter replacement; persistent P0171/P0174 lean conditions cause poor fuel economy and premature engine wear; undiagnosed misfires can damage pistons, rings, and catalytic hardware.
