Kia filed this with NHTSA as a manufacturer communication dated Sep 12, 2025, received Oct 1, 2025, about the electrical system. It names 3 model years (2022–2024). A manufacturer communication is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

The power sliding door does not reverse when an object is in its path. The door closed on my sons body. He was okay we were able to pull the handle to make it open again but it did not stop on its own. Another instance the door did not stop closing when a toy went into the door. The door just crunched the toy and shut while beeping

My passenger doors do not appear to have a sensor and do not stop when someone or something is in the way. Could be very dangerous. My arm almost got stuck in it. Had it been a child, they may not have had the reflexes to get out in time. Also. If the door is accidentally opened when pumping gas, will it stop? Likely not

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia PS788 a recall?
No. A manufacturer communication is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the PS788 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Kia warranty extension on file lists the ones Kia has filed.
Which vehicles does PS788 cover?
The manufacturer filed it against 3 model years: 2024 Kia Carnival, 2023 Kia Carnival, 2022 Kia Carnival. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
