    So here’s a weird one (searched and couldn’t find similar) the last few days when I’ve been driving up long hills on the freeway I’ve been hearing a rattle either from drive side dash area or beneath steering column area, goes away when level or downhill, any ideas?

    Spark knock from the engine. Try a tank of premium and see if it goes away.

    Most newer engines run on the ragged edge of spark knock as your best power/efficiency is there.
