Service bulletin SSM 46546

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

2016-2017 E-Series vehicles do not require the rear axle fluid fill level to be checked during PDI. The axle fluid fill level is set by the supplier and the addition or topping off of any fluid may overfill the rear axle housing above specification. In addition, replacing axle fluid with synthetic fluid will void the axle warranty.
