Service bulletin 21B36

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.

The customer can still unlock and/or start their vehicle using the key FOB. The customer can also unlock their vehicle using FordPass or the keypad code on the door, and they can start their vehicle using the Back Up Start passcode feature, if configured.
