Service bulletin 20B45

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

Certain 2020 Model Year Super Duty Vehicles with XL Trim and SYNC 3 Instrument Panel Cluster Replacement In some of the affected vehicles, a coding error may have caused a 2.3” display screen instrument panel cluster (IPC) to be installed in place of the 4.2” display screen IPC, as intended with the optional SYNC 3 package. While the display screen size is smaller and appearance differences are noticeable, there is no functional effect on the smaller display screen IPC.
