NHTSA Complaint #11340067 — 2017 KIA OPTIMA

POWER TRAIN; SHIFT LOCK SPECIFICALLY: HAD TO USE THE RELEASE CONTROL MORE THAN ONCE. WHILE DRIVING WHEN IT HAPPENS, I FEEL A SURGE/ DECLINE IN ACCELERATION(SOMETHING I REQUESTED BE CHECKED A YEAR AND A HALF AGO, BUT KIA SAID THEY COULD NOT RECREATE MY DESCRIPTION).CONTINUES TO DRIVE BUT SLUGGISH TO ACCELERATE. ONCE I PUT INTO "PARK" I CANNOT GET IT OUT OF PARK EXCEPT TO USE RELEASE. IT DID RESET(?) WHEN I TURNED THE CAR OFF. SUSPENSION; FIRST FEW MONTHS OF OWNING THE CAR I PERIODICALLY HEARD A CREAK IN REAR SUSPENSION HERE AND THERE WHEN BACKING OUT OF DRIVEWAY/GUTTER SLOPE. HAVE NOTICED AN INCREASED CREAKING AND MORE BOUNCE WHILE DRIVING OVER TIME BUT HAVE NOT EVEN OWNED CAR MORE THAN 2 YEARS.
