2010 DTS - i noticed early on that the cabin had a strong odor of exhaust fumes. i tried turning off the A/C, etc but the odor remained. i did notice, however that this only occurs at slower speeds (street driving). on the freeways, the odor is not present.

it doesn't matter if i'm in a group of cars at a light or simply rolling down the street alone, the odor of exhaust is still present.

anybody with a similar problem or aware of this being an issue with the DTS?

I have never before heard of this being a problem with anyone.
I have over 140,000 miles on two different 2006 DTS's and I have never smelled exhaust in the cabin...AT ANY SPEED...

I would be taking it to my dealer ASAP...that can be dangerous to you and anyone else in the car.

Be very careful. Fumes will kill you and a fuel leak will cause a fire.

No odors with my 2008, unless I start it up in the garage and let it idle there.

Zombie thread I know...but I just took my new to me 08' DTS back to the dealer for this very problem. I will update when I get it back.

The EGR is right between the firewall and the engine so its possible you have a leak there, but first I have heard of this as well, and work on these all the time.
