Can't say I have heard of it being an issue in the 10-11 like the 12s but did they change transmissions along with the LFX in 12? It's certainly plausible that it can go wrong though
Edit: I do have to ask. Have you looked at your spark plugs? On my dads HHR we felt something very similar to this and it would only do it while at idle And only in reverse or drive. When we pulled the plugs the porcelain was cracked and looked liked it was causing the pressure to escape. So it was causing a shuddering and jerking. But on his HHR is was much more of an intense jerk than what you Describe. It may not hurt to give it a try if the Torq converter doesn't go anywhere
