No, it is not wrong, but it could create conflict, and depending on your father's attitude and receptivity to receiving help for his chid, it could go wrong and be harmful to you. So, be careful.

Feel it out.....is he open to your advice, and is it the right time.
Maybe you could share it with your mother first, and she could pray about it, or you both could pray about it. Is it your heart to protect your mother or correct your father? Because if you see your mother getting hurt, worn out, tired, then you're being motivated to do something, but just don't waste your time if it is gonna go nowhere. You have a future too, a job, a marriage, or whatever it is, and you need knowledge and energy to do it.
As the bible says children are to obey their parents in the Lord, but this plays out differently in each household. And parents are not perfect, they make mistakes, cause harm, and sometimes the children are more capable and able to be a leader and the maturity.
So, a better way of looking at is, you are blessing to your parents, which is also, what the bible says, and hopefully they feel that way about you.
If they do, be thankful, because all households and families are not like that.
And when there is harmony and peace it is nice.
Hope this advice helps.
Make use of a multitude of counselors.
And many christian men, who are the leaders of their home, have different leadership styles, it is all way too confusing, but their has to be a choice, and a decision, and some kind of order, just like a business, or nothing gets down and you go around in circles.
God Bless with a good mind.
And remember to put yourself first also.
