What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.

What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 1,083 complaints with NHTSA since 2015. 522 of them name Power Train, Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2021 Kia Sorento, the 22 owners who gave an odometer reading for Power Train reported it at a median of 65,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The drive train and motor slow to a near stop in traffic when trying to clear a lane and makes it very dangerouos for other traffic to have to wait for me to clear a lane. There is something wrong and we complained about this before the warranty ran out, but they could not find anything. The car stops in traffic unexpectedly.

While driving my 2023 Sorento plug-in hybrid a msg appeared that Charging Stopped Check Cable. When you stop the car and try to drive it will not go into any gear, msg says Shifting Conditions Not Met and Unplug Vehicle to Start and the wheels are locked up (E-brake) and needs a tow truck with dollies in order to load.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Source: NHTSA, 49 CFR 579.5Is Kia TSB_TRA111_R2 a recall?
No. A service bulletin 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 TSB_TRA111_R2 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.
