The improved software reduces power consumption from the vehicle’s auxiliary battery and enhances its performance by preventing the vehicle's auto-flush door handles from remaining extended for prolonged periods when a smartphone with Digital Key 2 remains nearby the parked vehicle. To extend the auto-flush door handles in this circumstance, the driver should press the lock/unlock indentation on either front door handle.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036139-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036139-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11036139","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"KIA","model":"TELLURIDE","year_from":2027,"year_to":2027,"match":"exact","vehicle_ids":["2027_kia_telluride"]},{"make":"KIA","model":"TELLURIDE HYBRID","year_from":2027,"year_to":2027,"match":"base","vehicle_ids":["2027_kia_telluride"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
