WHY WOULD MY CAR FEEL AS IF ITS SLOWING DOWN ALMOST BRAKING WHEN I DRIVE I NEED

What is your question?

tHE CAR ALMOST JERKS AS IF IM BRAKING IN THE MIDDLE OF DRIVING AND I NEED TO GIVE IT MORE GAS TO AVOID SLOWING DOWN AND I CAN FEEL SOMETHING EITHER CATCHING OR RUBBING. I HAVE TO PRESS THE GAS MORE JUST TO GET ENOUGH POWER SO CAR DOES NO SLOW TO MUCH ON THE FREEWAY AND IT ALMOST FEELS LIKE IT WANTS TO LOCK UP ON THE WHEELS SOMETIMES WHILE DRIVING

What makes this problem better or worse?

nothing its random

How long has your 2009 Ford Flex had this problem?
