NHTSA Complaint #11425571 — 2021 KIA TELLURIDE

I DROVE MY BRAND NEW TELLURIDE OFF THE LOT WITH APPROXIMATELY 12 MILES ON IT. ABOUT A MONTH AFTER HAVING IT I NOTICED THE FOLLOWING: WHEN ENTERING A HIGHWAY FROM ABOUT 20-25 MPH, THE VEHICLE WOULD NOT GRADUALLY ACCELERATE ALLOWING ME TO ENTER THE HIGHWAY. AS I CONTINUE TO PRESS THE ACCELERATOR PEDAL THE RPMS WOULD EVENTUALLY JUMP UP AND THE VEHICLE WOULD LAUNCH ITSELF FORWARD. REACHING 5000-6000 RPMS. WHEN I LET OFF THE ACCELERATOR THE ENGINE WOULD DOWNSHIFT SIMILAR TO A MANUAL TRANSMISSION AND WOULD JERK AS IT CHANGED GEARS AND THE RPMs DECREASE. ADDITIONALLY, WHEN CREEPING IN TRAFFIC I NOTICE JERKY AND HESITATION FROM THE ENGINE/TRANSMISSION. THIS IS QUITE DANGEROUS AS ONE TIME IT ALMOST LAUNCHED ME INTO THE BACK OF THE VEHICLE IN FRONT OF ME. MERGING ONTO A HIGHWAY IS ALSO QUITE DANGEROUS AS I AM NOT CONFIDENT THE VEHICLE WILL ACCELERATE WHEN I ATTEMPT TO MERGE. I HAVE TAKEN IT TO A DEALERSHIP AND HAD THE TECHNICIAN DRIVE IT AND HE CONCURRED THAT THERE IS A PROBLEM. THE DEALERSHIP HAS TRIED WORKING WITH THE MANUFACTURER BUT TO NO AVAIL AFTER 3 MONTHS. NOW THE DEALERSHIP WON'T EVEN CALL ME BACK. THE DEALERSHIP, VIA THE RECOMMENDATION OF THE MANUFACTURER, HAS RESET "ADAPTIVE VALUES" AT LEAST 3 TIMES, BUT THAT DID NOT FIX THE PROBLEM. THERE ARE NO WARNING LIGHTS OR MESSAGES OF A PROBLEM. WHILE QUITE NOTICEABLE, THIS PROBLEM IS EVEN MORE NOTICEABLE WHEN IT IS IN SPORT MODE.
