Silverado 2500 4WD 8-cyl Diesel

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.

Silverado 2500 4WD 8-cyl Diesel

  • Automatic transmission
  • 400 miles
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.
