Summary

TECHNICAL SERVICE BULLETIN: SERVICE ACTION: AVN FACTORY RESET THROUGH DEALER MODE (SA640) - This bulletin provides information on accessing the Dealer Mode function on 2025MY Telluride (ON) models equipped with an Audio Video Navigation (AVN) head unit and performing a Dealer Mode Factory Reset. A factory reset is required on certain 2025MY Telluride (ON) vehicles produced between December 2, 2024, and November 17, 2025, as incomplete initialization of the head unit during manufacturing may prevent the telematics system from properly connecting to U.S. networks, resulting in Kia Connect activation issues. Other AVN functions, including rear‑view camera display, are not affected by this condition.

Owners of these vehicles have filed 23 complaints in the electrical category.
