SummaryTECHNICAL SERVICE BULLETIN: PRODUCT IMPROVEMENT CAMPAIGN: 2ND ROW SEAT (LH & RH) FOLDING TENSION SPRING REPLACEMENT (PI2602) - This bulletin provides information to enhance the second-row seatback recliner mechanism to dampen the motion of the manual seatback angle adjustment during the operation on certain 2022-2026MY Carnival (KA4) produced from 1/4/2021 through 4/14/2026 and certain 2025-2026MY Carnival Hybrid (KA4 HEV) vehicles produced from 5/21/2024 through 4/8/2026. To aid in the manual adjustment of the outboard second-row seatback in the subject vehicles, the seats are equipped with recliner springs that work in conjunction with a user-controlled seatback angle lever or walk-in lever. This seatback motion is controlled by the user to achieve their desired seat position. To improve usability, Kia has developed a newly designed second-row seatback recliner spring that will dampen the motion of the manual second-row seatback angle adjustment. (Note: Only the second-row outboard seats are affected. The second-row center seat, if equipped, is excluded from this campaign.)
