"Collision camera housing?" Is that what that thing is? I thought it was the guts to the rain sensing wipers. Oh well.
When I bought the car used, I looked down in the cupholder and said, "What is this?" A flat, rectangular piece of black plastic with four clips/hooks, one near each corner. When I went to tighten the rearview mirror, well that's where it goes. My flashlight revealed the hole, with circuitry.
Before my solution, the longest I could get that panel to stay in place was three days. I'd come out and find it in the cupholder, or on the
seat or the floor, and once in the narrow space between the passenger
seat and transmission tunnel. And once I looked for a good long while and finally found it in the pocket of the front passenger door - evidently one of my wife's friends had seen/sat on it and moved it there. All very annoying. I could not, like you, push on it hard enough to secure the hooks, even when it sounded and felt like they were snapping into place. A design flaw.
My solution is a strip of Gorilla black tape. Before that, I used four pieces of Scotch gloss finish multi task tape around the edges. But that got a bit compromised in the heat. The panel didn't fall out/off, but I had to periodically press everything back up nice and tight and thumb the tape back down securely. I think the Gorilla tape will be good for a long time. And if it starts to let go, I'll just clean up with isopropyl alcohol and apply a fresh strip. Should be good for many months, if not forever.
