Default 4.4.3 vibration problems

Since updating to 4.4.3, I've had some problems with vibration. Very often, I'll just stop getting haptic feedback. Sometimes in the middle of typing (right now even), when I'm unlocking the phone, long pressing, or touching the nav bar. It always seems to start working again in a few seconds or minutes.

I figured it might have been the 4.4.3 zip that I flashed, so I reset to stock and used fastboot to update with the official moto image, but even totally stock, fresh install, I'm having the same problems. I've reinstalled a few times now... Is anyone else having this issue, or could it be a hardware defect?

Also, I seem to have stopped getting the nice ascending vibration when twisting to open the camera. It's just a short single buzz. I hope that's just me and not moto's doing. That vibration was one of the most satisfying little features on the X haha.
