I have a dawn redwood that has the majority of its leaves curling. I've not seen this before, and I can't seem to find anything online that addresses this. Any insights?

Here is an excellent article on the requirements of Metasequoias. One of the things they want moist soil and I wonder if you have been having the very hot days with strong winds that we have been experiencing and if therefore, your soil is drying out.

I could not come up with much ; they are reasonably trouble-free.

Those sorts of symptoms could be caused by a herbicide.  Perhaps something used for weed control on the lawn was picked up by the root system of the tree.

The problem existed last year too. I had hoped it would correct itself with the new year's growth. We had a wetter than usual spring, and the soil is currently damp.

Erwin, thank you. I garden as chemically free as I can. I spot treat with round-up, rarely using more than a gallon mixture on a 5 ac. property.

Thanks for the extra information.  I don't know enough about this tree species to provide more help.
