I can tell you that our '04 Axiom is TERRIBLE about heating up on a long drive... but the heat is on the passenger side of the center console, perfectly located to scorch your passenger's feet. It's not heat blowing from the lower vents; it's heat radiating from under the carpet..
Lizardskin makes a ceramic based coating that would help with this heat issue in case you wanted to "fix" it.
