High Beam Headlight Adjustment Down
Is there a way to adjust the high beam headlights down without adjusting the low beams?
My low beams are perfect but my high beams are up in the trees.
I know the adjuster on the side in the engine compartment thru the little hole but that adjusts the whole bucket (I believe).

No. The projectors are a single unit. Both bulbs should be in alignment. Are Pass and driver lights the same or just one.
IF both are the same then that's how they are. If just one then sounds like the projector may be damaged in some way.

thats really odd because the high and lot beam projector are mounted to the same piece of plastic and the mounting surfaces are parallel, offset, but parallel.
here look:
so the centers of the high and low beams should be along the same plane....
the point of the highbeams is to throw as much light out as possible and scatter it high, unlike the lowbeams where the shield is on the bottom of the projector, the shield on the highbeams is on the top.

that's pretty interesting shot of the internals of the light. I've tried my high beams only a handful of times; doesn't seem to be shining way up at all. OP, do you think something happened to the inside of the light, or the bulbs were changed (which shouldn't throw things out of alignment, I'd think)?

Mine is a 2011. Nothing has been changed.
Shining on the garage door about 5' in front of me - the high beams are about 6" above the low beams. That means at 100' the center is 10' above the ground and climbing.
Will show to the dealer and see what they say on my next visit. Just thought if there was an easy adjustment - I would do it myself.

Ther is a procedure in the Owner or Service manual (I can't recall which) for aiming the headlights. It's more complicated than launching the Space Shuttle, but you might use it to see if yours meet the specs.

Check that both bulbs are seated properly in the housing otherwise I don't know what to tell ya.

And the problem with that is what? The point of the high beams are to see a lot further down the road when on a very dark road. They are aimed high in relation to the lows for this reason. There is also no independent adjustment of the lights, so there is no cure other than lowering the height adjustment of the headlights as a whole.
Not to be rude, but I wouldn't wast the dealership Tech's time.

The question is - what good does a high beam do if it is shining up into the trees. That is what mine are doing. If your on an open road and turn the high beams on - you can't tell you ever turned them on. That is the point of this discussion. Mine are shining up too high.
Low beams are perfect.
If you look at all the posts you will see that others have said there low and high are on the same parallel plane. Mine are not. My high beams are shining up compared to the low and going higher as you go out. Not flat at all.

I understand what you think to be the problem. But on a brand new car with both headlights doing this, I just don't see there being a fixable problem. If it was one light only, then maybe.
The other thing to consider is that the low beams are HID and have a very clean, sharp cut-off. The highs are a standard halogen bulb and tend to scatter the light down the road. I don't use my highs very much, but I've noticed that they light up high signs and such. Pretty sure what you are experiencing is just a design characteristic.
I'll be curious as to what the service department says about it

If you'll check the lights about 10 to 15 feet from your garage door or other flat surface, turn your low beams on, They'll probably be about 36" off the ground. Then switch on your high beams and see where the round light pattern is. My low beams cut right through the middle of the high beam pattern and the lights seem to be perfect when driving with lows and highs on.
If yours are not like this (or very close to this) then I would say the dealer should/will cover replacements under your warranty as this is a safety issue and not a cosmetic issue.
That would be your fix.

According to the service manager, mine seem to be a little high but not enough to warrent replacement. There is no adjustment other than lowering the entire assembly which would make the low beams lower than I want.
