To answer your question, no, it does not happen to other MDX drivers.
You've checked all your headlights, correct? So they're both working, and they're not flashing you because one is out? And you only have your low beams on, and not your high beams?
You can get a general picture of whether your headlights are properly aimed by focusing your vision on their beam pattern at night as you drive. If traffic signs at some distance (say, a couple blocks away) are illuminated by your low beam headlights, then they're too high. The low beam headlights should only be illuminating the immediate road for about 0.1 mile in front of the car, not far away (that's what the high beams are for).
It's easy to check the vertical alignment of your headlights yourself. Here's the procedure, as described in the service manual. You'll need to do this at dusk or after dark, not in bright daylight. Find a place (like in a parking lot or parking garage) where you have at least forty feet of level ground ending in a vertical surface (like a concrete or brick wall). Bring a long tape measure with you. Do the following procedure for each side, and block off the light from the headlight on the other side while you're doing it. There's a little square molded into the clear headlight lens on your car. Measure the vertical distance of that square from the ground. Park your car so that that square is exactly 25 feet from, and facing, the vertical surface, and turn on your low-beam headlights. The horizontal line where the light from the low-beam headlight cuts off should be exactly 2.1 inches lower (less distance from the ground) than the molded square in the lens is.
You can change the adjustment using a Philips screwdriver.
Or, you can take it to a shop and let them do it.
