update: Now getting a P041B code in addition to the U029E. DEF fault light comes and goes, but I can force it ON with "heavy acceleration" and after driving normally for a bit, the indicator resets. P041B appears to deal with EGR gas temperature.

Since this is part of the emissions system, my bet is that I'm on the hook for the repairs, given the 50K miles warranty limit. The dealership is hemming and hawing about whether it's covered- all depends on what the tech codes it out as (???) and if any given part(s) would be defective per GM!
