2010 Hyundai Santa Fe Check Engine Light Reset

Resetting the check engine light on a 2010 Hyundai Santa Fe may seem straightforward, but clearing codes without addressing the root cause can mask symptoms and allow damage to progress. At Coggin Deland Hyundai in Deland, FL, we recommend a complete diagnostic before any reset: our factory-calibrated scanners identify stored and pending codes, freeze-frame data, and readiness monitors so technicians can repair the underlying fault. A proper reset after repair helps ensure emissions readiness and preserves on-board monitoring for accurate future diagnostics. Choosing dealership service guarantees OEM parts, technician certification, and honest documentation of work performed—important for resale value and warranty coverage. We also offer transparent estimates, and our service financing options mean you can complete necessary repairs now and pay later. To protect your vehicle and avoid repeated visits, schedule service with Coggin Deland Hyundai and check our current service specials for savings.

2010 Hyundai Santa Fe Check Engine Light Codes

Common check engine codes for the 2010 Hyundai Santa Fe include P0420 (catalyst system efficiency below threshold), P0171/P0174 (fuel trim too lean), P0300 (random/multiple cylinder misfire), and P0135 (oxygen sensor heater circuit). Left unchecked, P0420 can lead to failed emissions tests and costly catalytic converter replacement; P0171/P0174 may cause poor fuel economy, drivability issues, and accelerated engine wear; P0300 can damage pistons or catalytic components if misfires persist. At Coggin Deland Hyundai, our certified technicians in Deland, FL, diagnose the specific cause and present OEM-recommended repairs with clear pricing and long-term cost savings.
