A pistol that scatters rounds inconsistently around the point of aim, and also has problems with functioning (FTE, FTF, stovepiping, etc.) bespeaks a serious problem with the barrel or the mating of the barrel to the slide. If you were trying to fix this on your own, the first thing to be done would be to replace the recoil spring assembly while examining the barrel for unusual wear on the hood or areas where it contacts the slide. Then maybe just look at the barrel to see if it is bent, warped, has a bulge, has a bad crown, etc.

All the best in hoping for S&W to fix it. Please post the outcome of this problem here, and tell the Forum what S&W says is the problem -- if they tell you in their repair order (sometimes they don't explain what they did, they just send it back).
