The most common reasons a 2016 Subaru Legacy cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.

Sensor: A faulty sensor can lead to incorrect readings, causing issues with engine performance or triggering warning lights on the dashboard.
Control Module: A faulty control module can result in erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent acceleration and poor engine response.

How urgent is it to address the non-functioning cruise control in my 2016 Subaru Legacy?

While a non-functioning cruise control system in your 2016 Subaru Legacy is not an immediate safety concern, it is still advisable to address the issue sooner rather than later. Ignoring this problem can lead to increased driver fatigue during long trips, as the cruise control feature is designed to enhance comfort and reduce the physical strain of maintaining speed. Additionally, the underlying causes of the malfunction—such as a failed control module or sensor issues—could potentially lead to more significant problems if left unchecked.
