This is going to turn into the mother of all definitional disputes, major and battle being the big ones.
In WWII Europe, the US got caught pretty good at the Bulge before grinding it back around. On the flip side Arnhem failed.
The Battle of Hürtgen Forest was a pretty unambiguous American defeat.

The battle of the Java sea featured the US in a coalition under Dutch overall command, but was definitely a major battle and definitely a defeat for the allies. The battle of lake Changjin, likewise, except the US was in overall command of the coalition.

Java sea, in WWII, and Yalu river, in Korea.
Basically the entire opening of the war in the Pacific--Philippines, for instance. Kasserine Pass as well, maybe.
