Service bulletin L-TT-0293-20 Rev

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

TT: NOTE: This document ONLY applies to 2020 ES & 2020 NX vehicles built before 10/01/2019. (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.
