Diesel Fuel System problem

Message came on dic saying low def 727 miles. Did not quite know what that meant. Found out. Gm says it should come on at 1000 miles. Nope. Came on 2 x 727 and 72. There is no way to check the def level. Someone realized this as the newer trucks have gauges or other ways to check. I feel this could become an issue if the vehicle goes into limp mode and no close places to purchase def. I talked to gm. They don't seem to concerned about the whole thing. A simple fix would be to make it like the transmission fluid check. Pull out the dip stick/check the fluid/add fluid if necessary through the same tube that the dipstick came out of. My truck has a tube under the hood where you add def. Again there is no way to see how much you need. You just keep adding till it spits out of the tube. I feel gm should take care of this issue with an update of some sort so a motorist vehicle suddenly starts slowing down on the highway. Thanks for your interest. .
