Cracked Y pipes still a problem for 07s?

[Carssuck]

I have been running my A/C a lot the past few weeks and the cab smells like exhaust, I am thinking the Y pipe is cracked.
I also thought they came up with a better design. Didn't they?

Same pipe my friend. Then again it could be the seal between the up-pipe and the EGR cooler or the EGR cooler to intake manifold gasket.

I had a leak on my downpipe and you could smell fumes when the blower motor was on. :blahblah1:

After all this time, you would think they would have addressed the piece of crap!:blahblah1:

Check your downpipe first. I also had a truck with one of the banjo bolts a little loose so it would leak a tiny amount of fuel and then burn it off on the block.
