Can you describe what's in the advert? Might help jog some memories.
A long shot here, since the lyrics you describe don't match either of these suggestions. Lone female singers with acoustic guitars are pretty plentiful at the moment...
Suggestion 1
Is it the Audi R8 advert? More information can be found in this post and if that's the one, the track is The Beep Beep Song by Simone White.
Suggestion 2
Is it the Saab 9-3 advert? More information can be found in this post and if that's the one, the track is Through Your Eyes by Nina Kinert.
As hez suggests, can you perhaps give us a few more details, even if it's just a brand name or a bit more of a description of what happens in the advert?
