I had a first year NNBS with no problems as have many others. It's not like it will be the first vehicle GM has ever made...
True words, but Ford said the same thing about their new and tested tough 6.0's back in the day and those were notoriously bad - mine was no exception to that. Left a bad taste in my mouth for purchasing a new run vehicle, especially with new or tweaked engines.
I'm sure the 2014's will be, by and large, rock solid...but for this kind of money I prefer to not take my chances. I'm one of those wait and let them figure the problems out over a couple years kind of people.
If it has been improved and proven to be as reliable, if not more so than the prior generation, then it wouldn't be off the table as a future purchase. That is, assuming I can stand the new look.[
