Kia filed this with NHTSA as a service bulletin dated Oct 19, 2023, received Nov 4, 2023, about the electrical system. It names 1 model year (2023). A service bulletin 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 12 complaints with NHTSA since 2015. 5 of them name Engine, 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.
When I started my car, during the warm-up process, it dropped revs and turned off. After several tries, it turned on. While driving, when the vehicle was stopped, it began to jerk slightly. The safety risk is that the car, while I am driving, could turn off and cause an accident, in which people could be at risk, including me.

I’ve been hearing this rattle noise mostly when I crank the vehicle. I took it to go get checked out and they heard it when I first brought it in for them to check. But when they got it to the back for mechanic to listen for it, of course it didn’t do it.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia TSB_ENG249 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_ENG249 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 TSB_ENG249 cover?
The manufacturer filed it against 1 model year: 2023 Kia Rio. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2023MY Rio (SC): built 30 Sep 2022 – 31 Aug 2023; Rio (SC): built 30 Sep 2022 – 31 Aug 2023 — the build date is on the certification label in the driver’s door jamb.
