My grandparent'* Aurora had no more than 25,000 miles on it when theirs went. Somewhere between 20,000 and 25,000.
Bad. :(
Didn't think anything of it at the time until I started noticing other Northstars doing the same thing...

Another feature of the Northstar engines is a "limp home" mode that allows the engine to continue running if all the coolant is lost. If the PCM senses an overheating condition, it temporarily disables up to half of the cylinders. This pumps enough air though the engine to keep temperatures from getting hot enough to cause any damage. Even so, GM says the vehicle should not be driven more than 50 miles in the limp-home mode

Vince, yes it does.
I'm not even wasting my time posting in defense of a very capable engine. Some idiot driving a Cadillac with low oil pressure after being significantly warned BY THE VEHICLE, and ignores it? WTF :?
