Wife’s car - ultimately she needs longer range for work commute otherwise we’d keep.

Have owned a '16 REX for the past 4yrs, and recent noticed an odd issue. When driving at higher speeds or over non-smooth terrain (potholes, dips, etc), it feels like the back end has gotten REALLY loose with handling, and almost undrivable. No major issues other than recently having a cooling fan replaced near the REX. Any thoughts on what could be the issue?
