What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationVOLUNTARY 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.

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.
