NHTSA Complaint #11099234 — 2013 HYUNDAI SONATA

I NEED TO ADD MORE DESCRIPTION TO MY PREVIOUS COMPLAINT. I DID NOT DESCRIBE THE PROBLEM IN DETAIL WHEN DRIVING AROUND IN THE CITY, COMING TO A STOP, (SOMETIMES THE BRAKE DOESN'T ENGAGE) BUT MORE OFTEN, THE CONCERN IS WHEN TRYING TO TAKE OFF AFTER COMING TO AN INTERSECTION, THERE MAY BE NO ACCELERATION FOR SEVERAL SECONDS TRYING TO TAKE OFF. IT BASICALLY JUST ROLLS UNTIL SOMETHING ENGAGES, THEN THE ACCELERATION BEGINS SLOWLY. ONCE THIS PROBLEM STARTS OCCURRING, IT IS HAPPENS CONSTANTLY, BUT IT DOES NOT OCCUR EVERY TIME I GET IN AND DRIVE AROUND. THIS BEGAN LAST SPRING (2017), I HAD IT WORKED ON AND THEY DIDN'T KNOW WHAT TO DO. I TOLD THE MECHANIC TO DRIVE AROUND (HYUNDAI SERVICE) AND THEY DIDN'T UNTIL THEY WANTED ME TO PICK IT UP. WE DROVE AND IT HAPPENED. SO, THEY 'FIXED' SOMETHING. IT WAS BETTER TEMPORARILY. NOT COMPLETELY FIXED, BUT NOT AS SCARY OF A SAFETY ISSUE. THEN IN THE COOLER WEATHER, IT DIDN'T OCCUR. NOW, THE PAST COUPLE OF WEEKS IT HAS BEGUN AGAIN, WORSE THAN BEFORE. I WILL NOT BE ABLE TO DRIVE THIS VEHICLE UNTIL IT IS FIXED, IT IS DANGEROUS!
