NHTSA Complaint #11621714 — 2016 KIA SORENTO

This is an ongoing issue, from the day I purchased the car used. The steering sticks and binds when turning to the left; not on an ordinary sharp turn at an intersection, but at highway speeds. Sometimes the steering sticks and must be corrected to avoid going into the opposite lane. Several diagnostic attempts have been made including alignment, recalibration, and replacement of the 4wd coupling. Car still wavers and sticks at speed when turning left. Unknown cause. No codes show. However, at one time, on the display (not the dashboard symbol display, the camera/radio display) a message appeared saying: Mechanism Failure.
