Service bulletin SSM 52064

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.

SSM 520762023-11-21. Service bulletin. Some 2019-2021 Edge/Nautilus vehicles equipped with all wheel drive (AWD) may exhibit a noise from the rear of the vehicle while approaching the vehicle or prior to starting engine. This may be due to the rear drive unit (RDU) actuator learning process. Reprogram the software in the AWD module to minimize the noise using the latest software level of the appropriate Ford diagnostic scan tool. If no other concerns or symptoms are present, further diagnosis or repairs are not recommended. For claiming, use causal part 4000 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
