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, which is associated with rear drive unit (RDU) actuator learning process. Update the driveline control module (DLCM) calibration to minimize the noise. 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.
