Certain vehicles may have a condition in which the transfer case actuator motor brake sticks in the open position inside the transfer case actuator assembly. If 1) the actuator motor brake sticks open, 2) the vehicle is on asurface with an angle greater than zero but less than two degrees, 3) the vehicle is parked in 4LO, 4) the system is warm, and 5) the vehicle ignition is turned ?Off,? there is potential for vehicle rollback due to the range fork slipping into neutral. The brake sticking condition will set diagnostic trouble code C0326 58 and a ?Service AWD? warning will appear on the driver information center. Dealers are to replace the transfer case actuator assembly.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10126015-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10126015-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10126015","components":[{"id":"brakes","name":"Brakes","parent":null},{"id":"parking-brake","name":"Parking brake","parent":"brakes"}],"codes":["C0326"],"topics":[],"vehicles":[{"make":"CADILLAC","model":"ESCALADE","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_cadillac_escalade"]},{"make":"CHEVROLET","model":"COLORADO","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_chevrolet_colorado"]},{"make":"CHEVROLET","model":"SILVERADO","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_chevrolet_silverado"]},{"make":"CHEVROLET","model":"SUBURBAN","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_chevrolet_suburban"]},{"make":"CHEVROLET","model":"TAHOE","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_chevrolet_tahoe"]},{"make":"GMC","model":"CANYON","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_gmc_canyon"]},{"make":"GMC","model":"SIERRA","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_gmc_sierra"]},{"make":"GMC","model":"YUKON","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_gmc_yukon"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
