NHTSA Complaint #11377258 — 2016 HYUNDAI SONATA

DURING LONG DISTANCE DRIVING ONCE THE VEHICLE IS STOPPED FOR GAS THE HEV WARNING LIGHT COMES ON. THE CAR WILL NOT RE-START FOR 15 -30 MINUTES. ONCE RESTARTED THE CHECK ENGINE LIGHT COMES ON. THIS HAS HAPPEND 3 TIMES. THE FIRST TWO THE THOUGHT WAS A LONG DISTANCE DRIVE IN THE HEAT OF SUMMER. THIS LAST TIME IT WAS FALL/WINTER SO THE HYPOTHSIS OF SUMMER HEAT WAS THROWN OUT THE WINDOW. THE MOST RECENT TIME THE GAS MILEAGE WENT DOWN DRASTICALLY AND THE VOLTAGE FOR THE ELECTRIC SYSTEM WAS ACTING ERRATICALLY. THE CHECK ENGINE LIGHT WAS ON FOR 2 DAYS BUT THE CAR WAS ONLY DRIVEN TO THE DEALER. THE DEALER QUICKLY FOUND THE PROBLEM AND REPAIRED UNDER WARRANTY "OPEN RECALL". THE CAR HAS NOT BEEN DRIVEN ANY LONG DISTANCES SINCE. THE DIAGNOSIS WAS "MAIN RELAY/POWER RELAY/CABLE (20-01-003H) CAUSED BY T4M. POWER RELAY MODULE MELTED AT RELAY" INSTALLED 37583-A8000-QQH: RELAY-HIGH VOLTAGE MAIN, 37514-G0000-QQH: RELAY ASSY-POWER, REPLACED POWER RELAY ASSY MODULE PER CAMPAIGN "WARRANTY" HOPE THIS INFORMATION HELPS OTHERS....HOPE THIS IS TRULY THE FIX AS IT IS AN "OPEN RECALL" THAT SHOULD BE A RECALL". GLAD THIS DID NOT CAUSE A FIRE.
