NHTSA Complaint #10908442 — 2012 HYUNDAI SONATA

I PURCHASED MY VEHICLE 1/21/15 CERTIFIED PRE-OWNED W/ 39,011 4/10/15 AS I WAS DRIVING ON A TOWN ROAD DOING APPROXIMATELY 45 MPH, THE VEHICLE SHUT OFF ON ME AND TURNED ITSELF BACK IMMEDIATELY. THE HEAT WAS NOT ON PRIOR TO THE SHUTDOWN, BUT WHEN THE CAR TURNED BACK ON, THE BLOWERS CAME ON FULL BLAST. I EXPLAINED TO THE DEALER IT WAS LIKE MY CAR WAS POSSESSED. MECHANIC ONLY TESTED THE BATTERY AT THIS TIME, BATTERY IS FINE, CAUSE IS UNKNOWN. 8/3/15 ENGINE SEIZED WITH WHILE DRIVING APPROXIMATELY 60 ON A STATE HIGHWAY. ENGINE WAS REPLACED AND LATER A RECALL WAS ANNOUNCED BY THE MANUFACTURER. 9/18/16 VEHICLE SHUT OFF AGAIN WHILE DRIVING ON AN INTERSTATE DOING APPROXIMATELY 80 MPH WHILE SWITCHING LANES. LOST POWER STEERING BRIEFLY AND THE VEHICLE CAME RIGHT BACK ON, ALL LIGHTS ILLUMINATED ON THE DASH, RADIO CAME BACK ON BLASTING (WAS NOT LIKE THAT PRIOR TO SHUTTING OFF). MAYBE IT WAS A COINCIDENCE OR NOT, BUT THE SECOND I TURNED MY LEFT TURN SIGNAL ON, IS WHEN THE VEHICLE SHUT OFF. IT CAME BACK ON MAYBE 3 SECONDS LATER. ORIGINAL DEALERSHIP CLAIMED A LOOSE CONNECTION WITH THE BATTERY CAUSED IT, HOWEVER, THEY DID NO FURTHER TESTING OR INVESTIGATING. IT IS CURRENTLY AT ANOTHER HYUNDAI DEALERSHIP GETTING ASSESSED. FROM 2/20/15 UNTIL PRESENT, I HAVE ALSO BEEN EXPERIENCING THE CONTROLS ON THE STEERING WHEEL NOT FUNCTIONING PROPERLY: EX. THE MODE BUTTON WILL MUTE THE VOLUME, THE CHANNEL CHANGER AND VOLUME WILL START MAKING CALLS ON MY BLUETOOTH CALL LOG OR ACTIVATE THE VOICE CONTROLS. VOLUME WILL SOMETIMES CHANGES THE CHANNEL OR WILL INCREASE INSTEAD OF DECREASE AND VICE VERSA. SOMETIMES THE CHANNEL CHANGER WILL CONTROL THE VOLUME OR MODE, THEY DO WHAT THEY WANT TO WHEN THEY WANT TO. CRUISE CONTROL IS INOPERABLE MOST OF THE TIME. I HAVE MULTIPLE VIDEOS AND HAVE SHOWN THE MECHANICS, BUT THEY CLAIM TO NEVER BE ABLE TO DUPLICATE THE PROBLEM. CAUSE, STILL UNKNOWN.
