This is a regionalism in parts of the US, which I’ve seen described as Pittsburgh and its surroundings. I come across it often and struggle with cognitive dissonance every time - I know of the regionalism but it feels so strongly like a glaring grammatical error. I see/hear the specific phrase “needs fixed” most often.
