ON 2 DIFFERENT DAYS THE CAR KILLED ON THE HIGHWAY. BOTH TIMES THE HYUNDAI SERVICE DEPT. LOOKED AT IT. THE FIRST TIME, THEY SAID THE SOFTWARE UPDATE THAT WAS WORKED ON A FEW MONTHS PREVIOUS, HAD A GLITCH IN IT. THE SECOND TIME THEY SAID THEY DIDN'T KNOW WHY IT HAPPENED. WHILE DRIVING THE RPMS WILL RACE UP BUT THE CAR DOESN'T MOVE MUCH. THEY SAID IT DIDN'T DO THAT WHEN THEY DROVE IT. ALSO SINCE THE FIRST SOFTWARE UPDATE WAS DONE , IF I DRIVE 80MPH (ON THE INTERSTATE HWY.) THE SEATS SHAKE.

I OWN THIS 2019 SONATA SINCE 1/16/19. WAS RUNING GOOD AT THE FIRST. BUT COUPLE TIMES START SHOWING THE ENGINE LIGHT FOR SECONDS. BUT ON APRIL SUNDAY 14 2019 MY CAR SHOWS THE ENGINE LIGHT AND THE TIRE CONTROL STABILIZER AT THE SAME TIME THEN THE CAR START SHAKING LOSSING SPEED,THE BRAKES GETTING HARD AND POWER STEERING. . LUCKY I WENT AT 10MPH TO 15MPH.THE VEHICLE WILL BE PLACED IN A TEMPORARY ENGINE PROTECTION MODE WITH REDUCED POWER AND ACCELERATION. NO SPEED NO ACCELERATION THEN I PARK IN A PARKING LOT FOR TOWING AT THE NEAREST HYUNDAI DEALERSHIP. TECHNITIA FOUND CODE( P0638 ) ACTIVE CODE AND (P211935002A00 THROTTLE BODY CARBON CLEANING- ADJUSTMENT AND FOUND RUBBER GROMMET STUCK IN THE THROTTLE BODY ROVED GROMMET. THIS CAUSE TROUBLE WITH THE INTAKE AND INJECTORS MAKING THE CAR LIMP AND STATE IN PROTECTION MODE. I HAVE LUCKY I WASN'T IN THE FREEWAY AT 55,60 TO 65 MPH. O CAN BE A DIFFERENT RISK AND DANGEROUS FOR ME AND OTHERS DRIVERS. PLEASE TAKE THIS NOTE SERIOUSLY BEFORE SOMETHING WORSE CAN HAPPEN TO OTHERS DRIVERS . THANK YOU SO MUCH.

I HAVE BEEN NOTIFIED MY WIFE'S CAR NEEDS THE HYUNDAI SERVICE CAMPAIGN NUMBER 953 PERFORMED ON HER CAR. SEE BELOW LINK. HTTPS://AUTOSERVICE.HYUNDAIUSA.COM/CAMPAIGN953/MICROSITETEMPLATE/MICROSITETEMPLATEVINVALIDATE/3402 MY CONCERN IS IF THIS SOFTWARE UPDATE IS PERFORMED ON HER CAR WHAT WILL HAPPEN WHEN THIS CAR GOES INTO THE SAFETY MODE? IF THIS CAR SLOWS DOWN AND REDUCES POWER WITH NO WARNING WHAT MAY HAPPEN? WHAT IF MY WIFE IS PULLING OUT IN TRAFFIC AND THE CAR GOES INTO THE ENGINE SAFETY MODE WITH ONCOMING TRAFFIC? I FEAR ONCE THE CAR GOES INTO THE SAFETY MODE WITH REDUCE POWER AND NO ADEQUATE WARNING SHE ME BE HIT BY ANOTHER VEHICLE. WHAT MEASURES HAS HYUNDAI TAKEN TO ENSURE A DRIVER HAS ADEQUATE WARNING OF THE VEHICLE GOING INTO SAFE MODE SO THEY CAN GET OUT OF HARMS WAY OF THE FLOW OF TRAFFIC TO ENSURE THEY WILL NOT BE HIT BEFORE THE VEHICLE GOES INTO SAFE MODE AND REDUCES POWER? ALL I AM TRYING TO DO IS PREVENT A POTENTIAL ACCIDENT WHEN THIS CAR GOES INTO SAFE MODE.

VEHICLE PURCHASE DATE SHOULD BE ON OR BEFORE INCIDENT DATE UPDATED 9/21/18*JB

Engine takes a long time to start up, about 10-15 seconds of pushing the start button starts engine which is probably not good for the car. Also, the car jolts/ wants to stop while driving. Has been an ongoing issue since the week of 9/5/22.
