Urea tank - DEF SCR problems with GM
Found this on the D/A forums. GM apparently has a few problems and while awaiting a recall to be devised, the SCR is being turned off at the dealers.

Oh, and the time I spend on FTE is, of course, worth it.

the worst vehicles I have ever seen have been GM products, funny those labels they put on have looked exactly the same since the '70's. if you have a long lasting reliable GM product I would say you got lucky. but people still seem to keep on buying.
I still remember the lumina's, berettas, astros, and those slant nose vans of the mid to early 90's ***** would come off in your hand, the door handle may break off, the dash would be bulging and the head liner sagging down on your head. ford has made some terds too, windstars and taurus come to mind and the 6.0, had a neighbor with an '06 6.0 had tons of problems sold it and bought an '11 dodge, too bad he didn't stick with ford I think a new one would have made him happy.

Look at Trucklands thread. He just found out his warranty was worth at least $2000.

A couple of thoughts, I'm really glad the friend did not give his Dmax back in the previous post. No 2011 Dmax and we would not have free 400/800. I do find it ironic at how easy (and quietly) GM was able to get an open ended exemption out of EPA and CARB. I seem to remember a bunch of folks (not here) bagging on Dodge about having an exemption since they weren't using DEF this year when in fact they just have a different strategy for treatment.
Other than having to fill it DEF is our best friend, it knocks down NOX emissions with out any performance affect in fact the opposite is true. A large portion of the fuel economy gains of our engines over the 6.4 is the reduction of EGR required due to the DEF doing the same job. If I had a choice I would have a 20 gallon DEF tank and no EGR system in a heartbeat. If for no other reason than the contamination of the oil it causes.
