NHTSA Complaint #11024125 — 2016 HYUNDAI SONATA PLUG-IN HYBRID

MY SONATA PHEV HAD HYBRID SYSTEM FAILED NOT ONCE, BUT TWICE WITHIN A SPAN OF 1.5 MONTHS. IT'S BEEN HARDLY 1.5 YEARS SINCE I HAD BOUGHT THIS CAR. IN BOTH CASES THE CHECK HYBRID SYSTEM WARNING COMES UP AND ENGINE LOOSES TOTAL POWER. THE 1ST TIME IT HAPPENED, IT WAS IN THE MIDDLE OF A BUSY 405 FREEWAY AND WAS LEFT ALL OF A SUDDEN WITH NO POWER ON THE ENGINE. EXTREMELY DANGEROUS AND LIFE THREATENING PROBLEM TO FACE WITH. WITH WHATEVER POWER WAS LEFT, WAS ABLE TO COAST TO THE RAMP ON THE RIGHT. STOPPING ANYWHERE IN 405 FREEWAY IS ABSOLUTELY DANGEROUS, EVEN ON THE SHOULDER (MANY PEOPLE INCLUDING COPS HAS BEEN REAR ENDED). THE 2ND TIME IT HAPPENED IT WAS ON A 3 LANE LOCAL PARKWAY STILL DANGEROUS AS I AM LEFT WITH NO POWER TO CONTROL THE CAR. THE CAR HAD TO BE TOWED TO THE DEALERSHIP IN BOTH CASES.THE DEALERSHIP TOOK 1 MONTH TO FIX THE CAR THE 1ST TIME. THEY ENDED UP REPLACING THE POWER RELAY ASSEMBLY WHICH HAD TO BE SHIPPED FROM SOUTH KOREA. IT RAN FOR CLOSE TO 1.5 MONTHS AND AGAIN THE SAME PROBLEM WITH THE CHECK HYBRID SYSTEM WARNING AND IT'S BACK AT THE DEALERSHIP. THE DEALERSHIP SAYS THAT THE POWER RELAY HAS GONE AGAIN AND HYUNDAI NOW WANTS TO SEE IF REPLACING THE HYBRID BATTERY WILL FIX IT. AS OF TODAY AFTER 18 DAYS THE CAR IS STILL IN THE SERVICE CENTRE.
