I have a new 2014 Chevy. 1/2 ton 4wd. pickup and have towed it on 2 occassions. when i get into vehicle a rubber or brake smell exists. the truck is put into neutral and rolls freely. no assist brake...
As previously stated, it is a coating of rubber dust on the exhaust system pipes. The dust is stirred up from the roadway by the passage of your vehicles. There is no way to avoid it. It is not "vehicle specific". I have occasionally encountered it after towing a Jeep for a long distance (several hundred miles) without starting it. It has been my experience that it dissipates rapidly, with no dire consequences.
