Happens to me some too. People THINK I have a really good DTL backhand. Problem is that SOMETIMES it was not supposed to be a dtl shot.
I completely agree with hitting it more in front. I let the racquet whip a little more to come around it if I want to really get a wide cross court.
Often my problem comes from the feet. If your feet don't get you there in time, or you are not set up well, your body will do the best it can to work with what you gave it.
Take a look at your preparation to see if you are giving yourself the opportunity to hit the ball out in front. If not, fix that.
