The name of the song is "Horndog," by Overseer.
When you said that the commercial might have been a Mitsubishi vehicle
other than the Montero, I guessed that you were remembering a recent
ad for the Mitsubishi Endeavor.
I went to the Music Room Forum, a discussion group that often has
useful information about songs in commercials, and there I learned
that the song in the Endeavor ad was "Horndog":

"Breathe" is used in the Outlander commercial. "Horndog" by Overseer
is used for the Endeavor."

To verify this, I searched newsgroups:
Google Groups Search: "song" + "mitsubishi endeavor"
This led to a post which also identified the Endeavor song as

Overseer / Horndog. We got a free CD of it at the Atlanta
Endeavor/Evolution Launch. They also have a lot of music by Dirty
Vegas, some of it is really good (Ghosts comes to mind)."

The brief clip which I posted earlier was downloaded from Kazaa. If
you would like to own the complete song on CD, it will be available on
Overseer's new album, "Wreckage," which will be in stores June 3, 2003
(after the animation ends on this site, there is information about
joining Overseer's email list):
I'm glad we found your song!
