TSB_CHA129_R12026-09-30. Service bulletin. POWER TRAIN. TECHNICAL SERVICE BULLETIN: AWD COUPLER NOISE/VIBRATION LOGIC IMPROVEMENT (Revision 1) - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to upgrade the 4-Wheel Drive ‘4WD’ system software on some 2020-2025MY Telluride (ON) vehicles produced from January 08, 2019 through December 17, 2025. The affected vehicles may exhibit a noise and/or a vibration, shudder, jerking, binding, or chattering sensation while turning at low speeds (10MPH – 15MPH). This concern may be caused by decreased oil friction within AWD coupling due to continuous vehicle operation in harsh conditions (high/low ambient temperatures, extended duration/distance driving).
