Why's my 2012 Cadillac SRX backup camera not working?

While there are a number of reasons why Your backup camera -- in a 2012 Cadillac SRX or otherwise -- would fail to work, Your most commonly going to run into issues with wiring. Since there's such an extensive cable run, it's quite possible that it's become short circuited or damaged. If You're inspecting, begin with the areas that connect to the camera itseLFAs well as the display. If this doesn't seem to be Your issue, You can always check the lens of the camera; it sounds elementary, but it's very possible that an obstruction is causing Your display problems. If this isn't Your cause, then You're likely looking at failed equipment, which will unfortunately necessitate replacement of either the camera, the display, or both.
