NHTSA 21V622000Reported Aug 9, 2021
Filed by
Kia America, Inc. (manufacturer recall no. SC216)
Units affected

Problem
Kia Motors America (Kia) is recalling certain 2016-2018 Forte 4-door, Forte Koup 2-door, and 2018-2019 Rio 4-door vehicles. The trunk latch may become damaged, preventing the opening of the trunk from the inside. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."
Risk
A person inside the trunk compartment may become trapped, increasing their risk of injury.
Remedy
Dealers will replace the trunk latch assembly, free of charge. Owner notification letters were mailed on February 10, 2022. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC216.
