I too had a cracked catalytic converter. The smell was noticeable for a couple months before it got obnoxious/dangerous. Over Thanksgiving, my wife warmed up the BS and the dogs had piled in fear we would leave them, and when I opened the door to load some things, I thought we were trying to kill our dogs.
Took it into the dealership and explained what I knew about this issue after reading this thread. They called back and said I had both a cracked catalyst and a leaky water pump. They replaced both under warranty, and had perhaps my best dealership experience in a long while.
Just drove it home from the dealership and the lack of the exhaust smell was indeed something I noticed!
The only code I had in my PCM was a P04F0, which is either a phantom code, or an unrelated problem. I'm hoping the recall work on the PCM/BCM update might also address the fuel vapor diagnostic, but we'll see. If the P04F0 comes back, I'll have to pick up a purge valve/hose assembly and assume that will resolve it.
