RITE NEXT TO THE OIL FILTER WAS A SMALL LEAK HAD SOME COROSION AROUND IT... FLUID COLOR WAS RED.. I THOUGHT IT WAS EITHER COOLANT OR TRANS FLUID.... THE AREA IT WAS LEAKING FROM LOOKED LIKE A CAP WITH TWO NUTS THAT FASTENED IT ON... DOES ANYONE WHO WHAT THIS IS? ITS A SMALL LEAK BUT I'D LIKE TO GET IT CORRECTED BEFORE IT BECOMES A BIG LEAK...

If it is a dried red residue, than it is probably antifreeze...On my RX300 it was leaking from the intake manifold and going down the backside of the engine to the bottom just between the engine and transmission. When dried it looks like a crust... transmission fluid would still be a wet film...

the cover you speak of is the cover for the block heater. there have been many posts regarding this, from what i can tell its fairly common, unless its wet and your coolant level is down i wouldnt worry about it. only fix would be to remove the cover and reseal and then refill with more coolant.

As someone already posted, that's the cover to where a block heater normally would be installed. You can either replace it, or if you're in a cold climate, why not just put a block heater in? It's easy enough to do - the only problem I had when I did it was that I stripped one of the bolts holding in the cover and ended up using vice grips to remove it. The key is to have the proper sized socket (it's an odd shape head on the bolt IIRC).
Do a Google search. Either here or at www.lexusownersclub.com or maybe some hybrid site, I can't remember, someone had a really good write up on putting in the block heater and it showed pics of the leaking cover you're talking about.

Here is the write up someone did for a block heater install on a Highlander Hybrid. The location of the block heater is the same, hybrid or not.
This is an excellent write up, with fantastic photos, and I give credit to the person that did it.
