This is VERY frustrating and very confusing also, an object I have in my scene keeps ‘snapping’ without me even holding ctrl or v or any other hotkey. I know the object is snapping because if I change the snap settings higher or lower it obeys those rules. I never turned anything or nor do I have an addon such as progrids or anything of that matter that snaps an object to an axis. On top of that it seems the object only moves freely on one axis, and snaps on another. This is happening a lot of game objects in my scenes but not all.
I know this is old post but I found the correct solution. There is a Snap to Grid Icon on Editor. Which is specific to object. Just disable that and you are good to go.! The right most icon in image. @Chrisasan
Same thing here, still in Unity 5.0.1. It happens at very odd times when objects are aligned to round numbers (sometimes just by chance). Manually changing their location in Inspector does not help at that point.
As FlyingMollusk_Team wrote, re-parenting is the only solution I have found. (Perhaps because they began at 0 on some axis in parent coordinates?)
I just googled this since it was happening to me, and it was because I had parented a bunch of objects underneath something. When I unparented them, the snapping stopped. (Not sure if this answers your question but that’s what worked for me!)
If you x scale is signed, say -1. Then the x position gets grid locked on a scale of 1.0f, which is 100pixels.
I found out after not getting my answer on unity3d and looking for one of my models which was not grid locked. After adjusting the model I then flipped her on the x scale. I then decided to make another adjustment just to find out she was grid locked. I flipped her back on the positive x scale, and she was no longer grid locked.

Fast forward to 2023, I had the same issue gladly found this thread.
Yeah, make sure the icon for Snapping is off in the Editor. It would be nice if Unity also had a way to disable it from the Grid menu globally or a tooltip that tells you a shortcut to use.
