NHTSA Complaint #11079053 — 2015 HYUNDAI SONATA

1/2 MILE AFTER STARTING MY VEHICLE AND DRIVING APPROX 30 MPH, MY CAR SHUTTERED AND SHOOK. PULLED OVER AND IT SEEMED TO FIX ITSELF SO I CONTINUED 23 MILES TO WORK. WAS APPROX 39 DEGREES ACCORDING TO CAR DASHBOARD. LEAVING WORK 9 HOURS LATER, I DROVE APPROX 1.5 MILES IN STOP AND GO TRAFFIC, SPEED NO HIGHER THAN 25-30 MPH, CROSSED OVER RR TRACKS AND THE CAR SHUTTERED AND THEN SHUT OFF COMPLETELY ROLLING TO A STOP. THREW ON MY HAZARDS AND THE SCREEN INDICATED I SHOULD PUT IT IN PARK AND RESTART. THE BATTERY LIGHT AND MASTER INDICATOR LIGHT CAME ON. CAR RESTARTED AND THE LIGHTS DISAPPEARED. WENT STRAIGHT TO HYUNDAI DEALER. THEY ATTEMPTED A 17 MILE ROAD TEST THE NEXT DAY AFTER THE CAR SAT OVERNIGHT AND IT DID NOT REPEAT THE ISSUE. NOTHING WAS STORED IN THE COMPUTER SYSTEM FROM WHEN THE LIGHTS CAME ON. THEY HAVE NO EXPLANATION. OIL WAS CHANGED AND TOOK CAR BACK AT 5PM THE DAY AFTER THE ISSUE TOOK PLACE. DROVE 24 MILES TO WORK TODAY AND IT DID NOT REPEAT YET.
