Official summary
Owner Notification Letter - On February 22, 2022, the 3G network will no longer support the in-vehicle services that previously were supported for your vehicle. The Telematics Control Unit (TCU) in your vehicle must be updated using the Over the Air (OTA) update to connect to the VoLTE network to continue communications. Honda strongly recommends updating your vehicle as soon as possible. After February 22, 2022, restoring services will require a customer pay TCU replacement performed by a service technician at an authorized dealer.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
