The driver's seat shifts towards the right rear when the vehicle accelerates or goes around a left hand turn (i.e. when forces push the driver towards the rear of the vehicle). The driver's seat shifts towards the left front when the vehicle brakes heavily or goes over speed bumps. Kia dealership says this is a known issue with the seat coming out of its track assembly, and confirmed by half a dozen reports on Reddit's Kia EV9 forum [XXX] ).

When operating the vehicle the driver seat will move diagonally from the right rear to the right front and back. This is sometimes accompanied by an audible clicking noise, other times not. We have been informed by our Kia dealer (Kia Englewood in Englewood, NJ) that the noise and movement are cause by a plate in the seat assembly being to thin causing it to flex and move. Dealer stated that other vehicles in the same model line (EV9) are demonstrating the same failure and that the dealer expects a recall to be issued.

Drivers seat moving diagonally back and forth left to right when your make left and right turns. The force the car makes, forces the drivers seat to shift. Its a huge safety concern, everyone that has an EV9, a crash can result in the driver being killed because if the seat moves left to right forward and back under heavy or even light g force, imagine during a crash. The seatbelt is on the seat, so your whole body would go flying into the windshield because the seat can't even stay in position with light or heavy movements. Several people have reported identical experiences that only indicate the problem is not just happening to one or a few cars. Kia of America refused to replace my seat and refused at the local kia service center in Daytona beach, FL acknowledge or be shown the replication of the safety hazard. Several others on Facebook and forums are trying to take to service centers, but with it being a complex matter of not just the seat bolts needing to be tightened and something above the seat frame causing the issue, "master technicians" have no idea what they are looking at.
