Our service advisors give clear time estimates and work to minimize downtime with efficient scheduling.

What is the most common reason for check engine light on a 2010 Hyundai Tucson?

Loose or damaged gas cap and EVAP system leaks are frequent, easily corrected causes.
Oxygen sensors, catalytic converter efficiency codes, ignition coils or spark plugs are common component failures.
Addressing these early at a certified dealership prevents fuel inefficiency and expensive downstream repairs.
Our factory-trained staff inspects, diagnoses and recommends repairs using OEM parts to protect performance and resale value.

2010 Hyundai Tucson Check Engine Light Flashing

A flashing check engine light on a 2010 Hyundai Tucson usually indicates a severe misfire or other active condition that can damage the catalytic converter if driven long distances. When the light flashes, reduce speed, avoid heavy acceleration, and pull over when safe. Continued driving risks expensive downstream damage and higher repair costs. Bring your Tucson to Courtesy Hyundai of Tampa immediately—our technicians use OEM diagnostics to isolate ignition, fuel, or emission failures and recommend repairs that protect warranty coverage. Prompt dealer service saves money over time by preventing converter replacement and restoring fuel efficiency and drivability.

2010 Hyundai Tucson Check Engine Light Codes

Common codes for a 2010 Hyundai Tucson include P0420 (catalyst efficiency), P0300–P0304 (misfires), P0171/P0174 (lean condition), P0455 (EVAP large leak), and P0135 (O2 sensor heater). Left unresolved, these issues lower fuel economy, increase emissions, and may eventually damage the catalytic converter—leading to costly replacements. Sensor repairs and replacements are typically less expensive than converter work, and timely dealer service often reduces total spend. At Courtesy Hyundai of Tampa we use OEM parts and factory procedures, which frequently cost less than independent shops over time and ensure warranty eligibility for covered repairs.

2010 Hyundai Tucson Check Engine Light Reset

Resetting the check engine light can be done with an OBD-II scanner or by clearing codes after a verified repair, but a reset without repair only hides the symptom. Our dealership performs a full diagnostic, corrects the root cause, and then clears codes while ensuring readiness monitors complete properly for emissions testing. Repairs covered under warranty must be performed at a certified dealership to maintain coverage. Choosing Courtesy Hyundai of Tampa guarantees OEM tooling, accurate resets, and documented service history—delivering immediate savings and protecting long-term value.
