Exhaust smell coming through the vents
I have a 2007.5 Silverado LMM Duramax. I have noticed at times there is a strong exhaust smell coming through the vents. I've done some research on this forum and it seems that the down pipe may be loose at the turbo when there is a regen occurring.
There is a GM Service Bulletin 'PIP 4360' that tells service how to correct this problem.
I know a few of you that have had this problem and had GM service fix it.
My truck was built Nov 2007 and it has a little over 26,000 miles on it.
My question is, would this be covered by warranty? The bumper-to-bumper warranty has expired, but would it be covered by the engine or emissions warranty?
