Sorry that you are having issues. Obviously not normal. We have not have this issue...18000 miles now.
People have been having some sensor malfunctions and this causes the ECM to do the wrong thing...here could be not pumping enough air (spooling the turbo faster) in or diesel to cause it to stutter...
Somebody had an injector replaced if i remember on this forum...but all these should throw a CEL i suspect...
If they do not fix it fast don't forget to look into getting a new one through lemon law buy back or similar.
Good luck and let us know how it goes
