With the new epa regulations requiring the dpf on diesel engines there is a problem with GM trucks, where as when the truck goes into regeneration mode at low speeds, (ie heavy traffic) the fumes emitted are sucked back into the cab of the truck through the ventilation system. In my truck regeneration will happen each tank full of diesel (1-2 times per week). At high speeds this is not an issue. When the fumes are sucked back into the truck the occupants eyes will burn and you start to feel sleepy and or sick to your stomach. I have researched on-line in some of the forums and others are complaining that children will actually vomit from the smell in the cab. It seems there is a fix to this by Chevy, however they are reluctant to correct the problem unless you make a large enough stink at the dealership level. I imagine because of the cost! it seems to me that an issue like this where fumes are being pulled into the vehicle is a safety problem that need to be addressed by an authority such as yourself. I cannot believe that these fumes are not going to eventually cause health issues, or even worst somebody falling asleep at the wheel and causing an accident. I just found out that there is a tsb from GM on this issue that I have been experiencing for over a year now but the dealerships don't tell you. I will be bringing my vehicle to the dealership next week and forcing this issue to get the part that needs to be fixed replaced.

Exhaust fumes entering the vehicle when coming to a complete stop. I have been to the dealer twice and they have observed the smell, but have no idea where it is coming from. They are suspecting that it is the new diesel after burner causing the smell.

I have had diesel exhaust fumes in the 2007 Silverado since I bought it new at the dealer. I put a carbon monixide detector in the truck. Went up to 495 lbs. Had it back to the dealer 3 times allready with no problem found.I sell diesel trucks for a living and found at least 80 other people on line and other places that have had the same problem. I am afraid to drive this vehicle myself let alone put my family in it.I have askes Chevrolet to buy the vehicle back, but I also want this NHTSA to look into this, not only for myself but all the rest of the people out there.
