Yes. Green card holders are expected to live primarily in the U.S. Trips under six months are usually fine, but longer absences can raise questions.

If you plan to stay outside the U.S. for more than a year, you should apply for a reentry permit before leaving. This helps protect your status.

I stayed abroad for eight months and was questioned at reentry. I was allowed back, but it was stressful. Keeping ties like a job or home in the U.S. helps.
