After 41 years with Mötley Crüe, Mars announced his retirement from touring in 2022, telling Variety: "My body just doesn't want to do it." He was replaced by John 5 shortly after.

In April 2023, Mars filed a lawsuit against his former bandmates, claiming they had excluded him from the band's business affairs and had been "trying to replace" him since 1987. Nikki Sixx responded to the allegations on social media platform X (formerly Twitter), writing: "We don't deserve this considering how many years we've been propping him up. We still wish him the best. We love you, Mick."

Legal drama aside, Mars's epic career has earned him an estimated net worth of $50 million.
