Well 2200 miles on my new 15 bighorn 5.7 hemi and I get a CEL, thought it might be a fluke so did the battery cable off reset. After about 40 miles another CEL so I take it to parts store and the code is shown P1D73, of course they don't know what it means, so goggle it and its those little vents in the grill not working. So I find a topic where it shows you what is wrong with it and how to fix it. Took about 5 minutes to get to it and see it is like a clamshell with a locking catch that comes undone sometimes and stops it. I squeezed it back together and added some metal tape across the latch to hopefully keep it from doing it again. Tested it and it works fine now. You have to love the internet, so far its saved me two trips to the dealer, one for a leaky third brake light and now this, plus id rather fix stuff myself so I know its done right.
