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

WHILE DRIVING, UNDER MANY DIFFERENT CONDITIONS, MY HYUNDAI SONATA STALLS. IT HAS HAPPENED OVER A DOZEN TIMES. AFTER PULLING OVER TO THE SIDE OF THE ROAD, I LET THE CAR SIT FOR A WHILE AND IT STARTS RIGHT BACK UP AGAIN. OCCASIONALLY I HAVE TO HAVE IT TOWED. IT DOES NOT SEEM TO OCCUR WHILE THE CAR HAS CRUISE CONTROL ON, EVEN WITHOUT IT BEING ENGAGED, JUST POWERED ON. *TR

THE CONSUMER'S HYUNDAI SONATA DEVELOPED THE FOLLOWING PROBLEMS: THE PAINT WAS PEELING, THE SUN ROOF WAS BROKEN, THE PASSENGER SIDE WINDOW WAS INOPERATIVE, THE BRAKES FAILED, THE SEATBELT BROKE, THE ENGINE BLEW UP AND THE AIR BAGS FAILED TO DEPLOY. *MR THE ENGINE SURGED. AS A RESULT OF THE ENGINE BLOWING, THE RIGHT SIDE DISINTEGRATED. *SC *JB

THIS CAR PRESENTS WITH A LOUD CLICKING SOUND WHICH IS VERY DISTRESSING.ONCE IT BEGINS IT LASTS FOR SEVERAL MINUTES SOUNDING FOR LONG PERIODS AND AT TIMES SHORT BURSTS. I HAVE TAKEN IT TO THE DEALER TWICE AND THE PROBLEM HAS BEEN NEITHER IDENTIFIED OR RECTIFIED. UNTIL LAST NIGHT I HAVE BEEN ALONE IN THE CAR WHEN THIS SOUND PRESENTS. LAST NIGHT WHEN IT PRESENTED THERE WERE PASSENGERS PRESENT. ALTHOUGH THE CAR DID NOT FALTER IT WAS NONE THE LESS VERY DISTRESSING FOR MY PASSENGERS AND ME. WE TURNED OFF OUR CELL PHONES AND SHUT OFF THE RADIO TO NO AVAIL. WITH NO RESOLUTION OR INFORMATION AS TO WHAT IS THE CAUSE I AM LEFT WONDERING IF I AM DRIVING TOWARDS SOME MALFUNCTION. THIS CLICKING SOUND ALWAYS PRESENTS WHILE DRIVING ON FREEWAYS AT FREEWAY SPEED.*AK
