What it means
嫌いがある means that a person, action, or thing has a tendency toward a particular pattern, usually one viewed as undesirable or excessive. It commonly describes recurring behavior, characteristics, or outcomes in a measured and somewhat formal way rather than making an absolute judgment. With verbs, it normally follows the dictionary form; with nouns, it follows の.
Usage note
嫌いがある does not normally mean that someone dislikes something; that meaning is expressed with 嫌いだ or 嫌いです. This construction often carries a critical or cautionary nuance and is more common in analytical, written, or formal contexts than in casual conversation.
