Service bulletin SSM 50257

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

Various 2014-2020 vehicles equipped with a 3G modem may experience a lack of 3G modem performance. This may be due to the 3G cellular service functionality being decommissioned starting August 2021 and through March 2022. As the 3G cellular service is decommissioned, vehicles equipped with the 3G telematics control unit (TCU) will lose MyFord Mobile and MyLincoln Mobile app functionality/connectivity. Repair or Replacement of the TCU should no longer be performed using existing service stock. Replacement of the 3G TCU for this concern will result in programming concerns and repairs should not be performed. The customer can pay to upgrade their 3G modem with a 4G modem by following the information in FSA 21B09. Refer to FSA 21B09 for reference and not for claiming.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
