Cole Hauser was raised by his mother, Cass Warner, and often mentions her on his official Instagram account. In December 2017, the actor shared a photo of himself and his mother on horseback with the caption, "My momma and me cruise the hills of Utah on horse back. Love (our) time together." He also posted an image of his mother, wife, and children, noting "three generations" and indicating his mother was quarantining with his family during the COVID-19 pandemic.
In the past, Cole also supported his mother's nonprofit The Dream Factory Project by participating in a video a conversation with his mother meant to inspire others interested in pursuing their dreams. In the video, he recalls his mother allowing him to attend acting camps as a teen, which inspired him to pursue it as a career. He notes, "I was affected by affecting people in a good way instead of a bad way."
When speaking to The Havok Journal, Cole also credited his maternal grandfather, Milton Sperling, with teaching him important values, such as being honest and always acknowledging your mistakes. "My family is innately hard working," he said. "Especially on my mom's side. They were Russian immigrants and they came over and built an empire at Warner Brothers."
