VOLUNTARY SERVICE CAMPAIGN: SMART CRUISE CONTROL SOFTWARE LOGIC IMPROVEMENT (SC344) - This bulletin provides information to upgrade the Smart Cruise Control (SCC) system software on 2024MY Telluride (ON) vehicles produced from May 16, 2023 through September 10, 2024. Due to radar signal interference in certain roadway conditions, the subject vehicles may unnecessarily and momentarily reduce speed when SCC is engaged, accompanied by the illumination of a “Collision Warning” message in the instrument cluster, a warning sound, as well as the activation of the vehicle’s brake lights. After the warnings cease, the vehicle will accelerate normally to the SCC set speed. Dealers will upgrade the software logic of the front radar (FR_RADAR) system to prevent unnecessary reduction in vehicle speed.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches Kia’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 227 complaints with NHTSA since 2015. 91 of them name Electrical System, Forward Collision Avoidance — 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.
The contact's father owns a 2024 Kia Telluride. The contact stated that after parking the vehicle while away from home, the entire instrument panel had gone blank upon the start of the engine without warning.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SC344 a recall?
No. A service campaign 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 SC344 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does SC344 cover?
The manufacturer filed it against 1 model year: 2024 Kia Telluride. 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: 2024MY Telluride (ON): built 16 May 2023 – 10 Sep 2024; Telluride (ON): built 16 May 2023 – 10 Sep 2024 — the build date is on the certification label in the driver’s door jamb.
