NHTSA Complaint #10383907 — 2003 HYUNDAI SONATA

2003 HYUNDAI SONATA EGR ISSUES (CHECK ENGINE LIGHT 401)- I'VE BEEN HAVING PERSISTENT ISSUES WITH MY VEHICLE'S EGR SYSTEM FOR OVER A YEAR NOW. I HAVE REPLACED THE ENTIRE EGR SYSTEM INCLUDING THE EGR VALVE, SOLENOID, ETC. I HAVE ALSO HAD TO REPLACE OTHER PARTS THAT HAVE FAILED DUE TO THE MALFUNCTIONING EGR - IGNITION COILS, SPARK PLUGS. EVEN AFTER REPLACING ALL THESE PARTS, MY VEHICLE STILL COMPLAINS ABOUT THE EGR WITH CHECK ENGINE LIGHT CONSTANTLY ON (401). I HAVE ALSO BEEN GETTING VERY POOR MILEAGE. I CONTACTED HYUNDAI ABOUT A TSB THEY SENT OUT TO DEALERS FOR EGR DIAGNOSIS. HYUNDAI DENIED ASSISTANCE WITH THIS ISSUE AND ASKED ME TO CONTACT THE DEALERSHIP DIRECTLY. THE DEALER WANTS TO CHARGE ME A DIAGNOSTIC FEE TO LOOK INTO THE ISSUE + FEES FOR PARTS. SEARCHING ON THE INTERNET, I FOUND SEVERAL CASES OF EGR MALFUNCTIONING WITH 2003 MODELS. HYUNDAI NEEDS TO LOOK INTO THIS. *TR
