Our 2005 Voyage had the same issue and I have seen threads on this before, here is one>>>

I was able to get ours adjusted after some patient trial and error. 1st put some tape around the hood bay opening to protect it while "adjusting". There are height adjustments on the hood but those dont seem to be the problem most of the time. The adjustments on the body portion will be more likely the issue, I scribed my starting points on ALL adjustment areas then started moving things until I could see I was going the right direction. I then adjusted the hood height (top to bottom) last. If it is really out you may have to increase length of the slots in the adjustment holes, better to remove the hood if needed to access the hinges, a die grinder bit works well and you should not need to completely remove the hinge assy. Its hard to describe how this is done but if you are patient you will get it right. Just remember to start with a reference point. I did mine a year ago and it has been fine since. 5K miles since.
Good luck
