Check Engine Light Flashing

The check engine light flashing on a 2012 Hyundai Genesis is an urgent alert — it often means an active misfire that can allow unburned fuel into the exhaust stream and overheat or damage the catalytic converter. When you see a flashing light, reduce speed, avoid heavy loads on the engine, and get the vehicle off the road safely. At Herb Chambers Hyundai of Auburn our technicians treat flashing lights as high priority: we perform a priority diagnostic to identify misfire causes, which commonly include worn spark plugs, ignition coils, or fuel delivery issues. We also test the charging system and battery since electrical problems can sometimes cause erratic engine behavior. Choosing our dealership means same-day attention when possible, OEM parts for reliable repair, and technician certification that protects your warranty. We offer service financing to get you back on the road today and transparent pricing so you understand immediate costs and long-term savings. Check our service specials and schedule service online to reserve an appointment — prompt dealer service prevents small issues from becoming expensive repairs and preserves your Genesis’s performance and value.

2012 Hyundai Genesis Check Engine Light Codes

The most common check engine light codes on a 2012 Hyundai Genesis include P0300 (random/multiple cylinder misfire), P0420 (catalyst system efficiency low), P0171/P0174 (fuel trim lean), and EVAP codes such as P0455 (large EVAP leak). Each code carries potential costs if ignored: ongoing misfires can destroy the catalytic converter ($1,000+), unaddressed fuel trim issues reduce fuel economy and engine life, and EVAP leaks can cause failed emissions tests and intermittent drivability issues.

We emphasize OEM parts, transparent estimates, and a clear explanation of immediate versus deferred work, which delivers both immediate savings and long-term value by avoiding unnecessary repairs.
