NHTSA Complaint #11364717 — 2018 KIA STINGER

I WAS DRIVING ON INTERSTATE GOING 70MPH WITH THE ADAPTIVE CRUISE ON AND MY SPEED SUDDENLY DROPS TO 50 ( LIKE SNAPPING YOUR FINGERS ). SCARED THE HECK OUT OF ME. WHEN I STOPPED I CHECKED THE FRONT SENSORS TO MAKE SURE THERE WAS NOTHING BLOCKING IT. A COUPLE WEEKS LATER THE SAME THING HAPPENED GOING ABOUT 70 ON INTERSTATE AND THE SPEED SUDDENLY DROPS TO ABOUT 50, BUT THIS TIME THE TRUCK BEHIND ME ALMOST REAR ENDED ME. BOTH TIMES WHEN THE SPEED DROPPED LIKE THAT I WAS FREAKING OUT AND TRYING TO GET MY FOOT BACK ON THE GAS AND GET MY SPEED BACK UP. A COUPLE WEEKS LATER I WAS GOING ABOUT 35 AND DID NOT HAVE THE ADAPTIVE CRUISE ON AND IT SUDDENLY STOPS AGAIN. THIS TIME THE CRASH WARNING LIGHT SHOWED UP ON THE DASHBOARD AND THE ERROR WARNING CAME UP AND SAID THE AUTONOMOUS BREAKING SYSTEM IS DISABLED. WE TOOK A PICTURE OF THE DASHBOARD. ON THE BOTTOM LEFT CORNER OF THE PICTURE IT SAYS CRUISE AND SHOWS THE ERROR LIGHTS ON THE DASHBOARD. CRUISE WAS NOT ON SO I ASSUME IT WAS PART OF THE ERROR THAT CAME ON WITH THE DASHBOARD LIGHTS. I AM SCARED TO DEATH TO DRIVE MY CAR NOW. I HAVE 2 GRANDKIDS THAT ARE IN MY CAR 3-4 TIMES A WEEK. GOD FORBID I GET HIT AND SOMETHING HAPPENS TO MY BABIES!!! I TOOK THE CAR TO HENDRICK KIA IN CONCORD, NC SO THEY COULD SEE WHAT WAS WRONG. WHEN THEY HOOKED THE CAR UP TO THE COMPUTER NO ERROR CODES SHOWED UP. ONE OF THE GUYS HAS BEEN DRIVING MY CAR HOME AND TO WORK FOR 2 DAYS AND THE PROBLEM HAS NOT HAPPENED AGAIN. I DON'T KNOW WHAT TO DO NOW.
