Exhaust smell from vents on 2006 Buick Lucerne

I hit a deer about a year ago. Ever since that time I get an exhaust smell in my vehicle if it is running but idle. I don't notice it once I am going down the road. Unfortunately this is not always consistent so everytime I have taken it to the shop they have not been able to witness this. Passengers in the vehicle have also noticed this so not just me! One shop mentioned something about an air pump system. Any thoughts?
