Service bulletin SSM 52008

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

Some 2023 Bronco/Corsair/F-150/F-Super Duty vehicles may exhibit a DTC P1674 in the GWM after an OTA update. This OTA update is delivered in two downloads. If the GWM is tested between OTAs, this code will be present. This DTC does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle. The software update that addresses the symptom will be sent via Ford Power-Up software updates delivered over-the-air (OTA) to connected vehicles that have automatic updates enabled through the center display screen.
