Please provide any additional information below.

While on Huntsman Altimor tonight, health levels were not displaying correctly. For example, one raid member died but Grid2 showed them at full health. Another example, my health was shown at 4% but when I was actually at 80%. This was the same for most of the raid from what I could tell.

Can you  confirm if this is a permanent issue in that boss, or maybe only happened once ?

Health code has not changed in a lot of months so i bet it was a glitch triggered by some external cause, like a network problem o some kind of crash in the game.

It is continuing and I'm seeing it in other areas now. Example, I was just in the Maw and had the same issue. I didn't notice until my screen flashed red because of low health but Grid2 was showing me at full health.

This issue has no sense, reinstall Grid2 and disable all other addons.

You can check too if the health update frequency (Goto Statuses>Health&heals>heal-current) is set to Instant if this is the case you must change it to normal.

I can confirm a similar issue that is affecting my pet's health frame and causing it to not update (i.e. I can target my pet while it's getting hit by mobs, but the grid frame stays full using Retail version 1.1.2-beta).  However, reverting to Retail version 1.1.1-alpha and reloading my UI resolves the issue.  When troubleshooting with 1.1.2-beta, I tried various things like changing health update frequency from instant -> normal, reinstalling, and reloading to no avail.

Pet healths not updated  is a new bug introduced in version 1.1.2-beta, pet health bars are not updated at all in this version. 

Instead Reynolds reports  random health values for players, but the addon is not so broken, so this is probably a network connection problem, not related to Grid2.
