NHTSA Complaint #10706089 — 2015 HYUNDAI SONATA

THIS IS THE SECOND 2015 HYUNDAI SONATA WHICH HAD COMPUTER PROBLEMS. THE FIRST ONE PURCHASED IN JULY 2014, HYUNDAI TOOK IT BACK IN DEC 2014 BECAUSE OF THE COMPUTER PROBLEMS. THE SECOND PICKED UP IN DEC 2014 CURRENTLY HAS APPROXIMATELY 2900MILES WITH THE SAME BASIC COMPUTER ISSUES. BOTH VEHICLES WHEN TRAVELING FROM ABOUT 40 TO 65MPH THE ENGINE'S COMPUTER SYSTEM WOULD CUT THE SPEED DOWN AND LOSE COMPRESSION TO APPROXIMATELY 20MPH TO PROTECT THE VEHICLE FROM SOME KIND OF ENGINE DAMAGE. YOU WOULD BE FORCED TO GET OFF THE ROAD AND SHUT THE VEHICLE OFF. ONCE THE ENGINE WAS OFF 5 MINUTES THE ENGINE WOULD START UP, THE CHECK ENGINE/ANTI SKID LIGHTS WOULD STAY ON SO THAT THE DEALERSHIP COULD SEE WHAT CODES WERE CAUSING THE PROBLEM. THE FIRST VEHICLE WAS ASSIGNED A CASE# BY HYUNDAI -CASE# 6788232 AND WAS FINALLY TAKEN BACK BY HYUNDAI IN DEC 2014 AFTER BEING OUT OF SERVICE FOR WELL OVER 35 DAYS DUE TO THE CONTINUED COMPUTER PROBLEMS. THE REPLACEMENT VEHICLE RECENTLY HAD 3 INCIDENTS WHILE TRAVELING AT APPROX. 65MPH THE ENGINE WOULD GO TO 20MPH WITHOUT WARNING. THE ONLY EXCEPTION WAS THAT WHEN I RESTARTED THE VEHICLE THE CHECK ENGINE LIGHT WOULD REMAIN ON UNTIL I TURNED OFF THE VEHICLE. WHEN I RESTARTED THE VEHICLE THE CHECK ENGINE LIGHT WENT OFF LEAVING ME IN A DIFFICULT POSITION WHEN BRINGING THE VEHICLE IN FOR SERVICE, THE COMPUTER DIDN'T STORE THE EVENT TO VERIFY THE PROBLEM. THE DEALER SAID IF IT OCCURS AGAIN TO LET THEM KNOW AND THEY WOULD CONTACT THEIR TECHNICAL HOTLINE. THE SERVICE DEPT KNOWS THERE IS A PROBLEM SINCE THEY WENT THROUGH THIS WITH ME ON THE FIRST VEHICLE, THAT'S WHY THEY TOOK THE VEHICLE BACK. I ESTABLISHED A NEW CASE FILE [XXX] ON 4/16/2015 WITH HYUNDAI CONSUMER AFFAIRS. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
