What have you done to your CX-5 today?

On mine, no lubrication altered the "creaking" noises. Particularly when very cold winter temps it (sub-0ºF), nothing would make it function well. It was still bolted-in and all, still moving, no breaks in the arm itself ... just very noisy operation.

Then you must need a new door check arm. In my case whenever the creaking noise starts happening from the check arm, a lubrication job even with WD-40 would quiet it down nicely and for a long period of time.

Yeah. Something in the "control" end of the arm assembly had seized up. No amount of lubrication would change its operation. Peeking in through the arm's access "port" area, it's clear that the delrin (?) component inside had been failing, as it was chewed-up and marred. However it actually holds onto the arm and/or attenuates the arm's movements, that had failed. Door still worked, but the arm's "guts" (inside the "business" end of things) wasn't doing well. The swap works nicely. It's utterly silent, now.

Might do an annual spritzing of a plastics-tolerant lubricating spray, into that spot on the various arm assemblies on each of the doors. If nothing else, to help keep minor rusting at bay, and to help keep that delrin/plastic piece as "slippery" as possible for the arm. Still, even without doing that, it's likely now got 10+ years' worth of life coming. Hardly a must-do.
