NHTSA Complaint #11131560 — 2013 HYUNDAI SONATA HYBRID

ON 05/10/2018, I NOTICED SEVERE VIBRATION AND CLUNKING IN STEERING WHEEL. BROUGHT VEHICLE TO HYUNDAI DEALER AND THEY REPLACED THE FLEXIBLE COUPLING IN THE STEERING COLUMN DUE TO WEAR. ON 08/08/2018, I BROUGHT THE VEHICLE TO THE HYUNDAI DEALER FOR ROUTINE SERVICE AND ASKED THEM TO CHECK THE BRAKES AS I EXPERIENCED AN INTERMITTENT LOUD SQUEAKING FROM THE BRAKE PEDAL. THEY WERE UNABLE TO DIAGNOSE THE PROBLEM. ON 09/25/2018, I ATTEMPTED TO START THE VEHICLE FROM A STATIONARY POSITION AND WHEN I DEPRESSED THE BRAKE, THE PEDAL WENT ALL THE WAY TO THE FLOOR AND A WARNING CAME ON THE DASH ADVISING ME THAT THE BRAKES HAD FAILED AND I NEEDED TO STOP IMMEDIATELY. I SHUT THE VEHICLE OFF AND THEN ATTEMPTED TO RESTART. UPON RESTART THE WARNING CONDITION DID NOT REOCCUR. VEHICLE TOWED TO HYUNDAI DEALER FOR DIAGNOSIS. I WAS ADVISED THAT THE ISSUE SEEMS TO HAVE CORRECTED ITSELF AND THE BRAKE SYSTEM SIMPLY NEEDED TO BE RECALIBRATED.
