NHTSA Complaint #11205919 — 2018 HYUNDAI SONATA

I WAS EXITING THE FREEWAY AND LOST POWER, COULD NOT ACCELERATE, BLINKING ENGINE CAME ON AND ON MY SCREEN IT SAID "A POSSIBLE CONDITION WITH YOU ENGINE CONTROL SYSTEM HAS BEEN DETECTED. A FULL SYSTEM CHECK RECOMMENDED TO BE DONE WHEN CONVENIENT. PLEASE CONTACT YOU LOCAL DEALERSHIP FOR AN APPOINTMENT" I WAS ABLE TO GET TO AN AREA AND HAVE IT TOWED. THIS COULD OF BEEN VERY SCARY AND DANGEROUS IF I HAD STILL BEEN ON THE FREEWAY DOING 70! I COULD NOT HAVE DRIVEN IT, IT WAS MISSING AND WOULDN'T GET ABOVE 20-30 MPH. I HAD THE KNOCK SENSOR SOFTWARE UPDATE DONE AT THE DEALER THE WEEK PRIOR TO THIS HAPPENING. THE DEALER IS SAYING THE WIRING HARNESS NEEDS REPLACED AND WILL NOT BE AVAILABLE UNTIL THE END OF THE MONTH! MANY ON HERE HAVE WAITED MONTHS I HOPE THAT IS NOT THE CASE. I'VE READ NUMEROUS COMPLAINTS ON HERE AND OTHER SITES THAT THIS IS HAPPENING AFTER THE UPDATE. MY CAR SEEMED FINE BEFORE THEY DID THE UPDATE. SOME PEOPLE NEED NEW ENGINES! HOW DO I KNOW THAT MY ENGINE DOESN'T HAVE DAMAGE, I ASSUME THAT HYUNDAI KNOWS SOMETHING SINCE WITH THE SENSOR UPDATE THEY EXTENDED MY 100K WARRANTY TO 120K. IT SAID THE SENSOR IS TO HELP CATCH POSSIBLE ROD BEARING WEAR AND EXTENDS WARRANTY MUST MEAN THEY EXPECT ENGINES TO HAVE PROBLEMS! WHAT IS GOING ON HERE AND WHY ISN'T THERE ANY OFFICIAL RECALL? MY CAR ONLY HAS 20K I DON'T EXPECT THIS KIND OF PROBLEM. I LEASED CARS FOR MANY YEARS BUT SINCE I'M CLOSE TO RETIRING I BOUGHT THIS WISH I WAS STILL LEASING SO I COULD GET OUT FROM UNDER THIS IN 2 YEARS!
