Some of the affected vehicles may exhibit a popping noise from one or both outside sideview mirror(s) after the auto fold/unfold function is enabled and the vehicle is locked. This condition is caused by the SBCM sending an additional fold command after the mirrors have already completed the folding operation. This condition does not affect the ability of the mirror to fold or unfold.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036629-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036629-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11036629","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"visibility","name":"Glass, wipers and mirrors","parent":null},{"id":"wiper","name":"Wipers and washers","parent":"visibility"}],"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.
