Service bulletin B17120D

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

Servicenews Article - If any of the accessory rear parking sensors look crooked or have recessed into the bumper, make sure the two clips on the rear bumper harness were removed as called out in the installation instructions. If they weren't, they can cause too much tension on the sensors with the harness installed, resulting in this issue.
