TT: NOTE: This document ONLY applies to 2020 ES & 2020 NX vehicles built before 10/01/2020. (Vehicles built after that date use AT&T WiFi, not Verizon) Head unit telematics services become inoperative after DCM replacement and activation if the guest has an ACTIVE Verizon Wi-Fi Pre-Paid subscription. Head unit services include Wi-Fi, Destination Assist, Dynamic Navigation, and Dynamic Voice Recognition. Verizon is not able to transfer the Pre-Paid subscription to the new DCM automatically. As a result, the guest is unable to use their head unit telematics services. At this time if the DCM is replaced and activated before confirming the guests Wi-Fi subscription status, this may require Verizon?s IT to perform a manual fix on the customer?s account. To simplify the diagnosis and prevent the unnecessary replacement of parts, please refer to the procedure below. NOTE: This Tech Tip does not apply if the guest is currently under their Wi-Fi Trial.
What this bulletin may mean before buying
Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
