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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11021132-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11021132-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11021132","components":[{"id":"driver-assistance","name":"Driver assistance","parent":null},{"id":"electrical","name":"Electrical system","parent":null},{"id":"speed-control","name":"Throttle and cruise control","parent":null},{"id":"adaptive-cruise","name":"Adaptive cruise control","parent":"driver-assistance"}],"codes":[],"topics":[],"vehicles":[{"make":"KIA","model":"TELLURIDE","year_from":2024,"year_to":2024,"match":"exact","vehicle_ids":["2024_kia_telluride"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
