Mick Mars played with Mötley Crüe for over four decades. But he stepped away from touring in 2022, and it led to a messy legal battle and accusations between him and his former bandmates. The band claims he left due to health problems, but Mars insists he was unfairly pushed out. Here’s a breakdown of what happened.
Mick Mars’ Health Struggles and Retirement from Touring

Mick Mars has suffered from Ankylosing Spondylitis (AS) since he was 27. This is a painful disease that mainly affects the spine and pelvis and makes movement difficult. He continued performing despite the pain over the years, but by 2022, it became too much.
During Mötley Crüe’s 2022 stadium tour, Mars told the band that it would be his last. He couldn’t handle the physical toll of traveling and performing every night. But he made it clear that he still wanted to be part of the band, record new music, and possibly do smaller performances, like a residency in Las Vegas.
Mars officially announced he was retiring from touring on October 26, 2022. The next day, Mötley Crüe announced that John 5 would take his place.
Did Mötley Crüe Fire Mick Mars?

Mars believed he was stepping back only from live shows, but the band treated it as a full departure. He sued them in April 2023, claiming they tried to force him out of the band completely. He refused to sign a contract that would cut his earnings from 25% to 5% and eventually to nothing.
In response, Mötley Crüe stated that they didn’t fire him but had to move forward without him. Nikki Sixx later explained that they were ‘forced’ to replace Mars because he could no longer tour. He compared it to a football team replacing an injured player.
Mars, however, didn’t see it that way. He accused the band of trying to erase his contributions and legacy, saying:
“How can you fire Mr. Heinz from Heinz ketchup? He owns it.”
He also claimed that the band had been trying to replace him since 1987 but couldn’t because he was one of the original members and helped start the band.
Legal Battle and Court Ruling

Mars’ lawsuit accused Mötley Crüe of wrongfully removing him as a shareholder and refusing to let him see financial records. He also said that the band ignored him when he asked to check business documents related to their touring companies.
In January 2024, a judge ruled that the band delayed giving Mars the documents he requested and ordered them to pay his legal fees. The case was considered “moot” since the band eventually handed over the records, but the bigger issue —if they illegally removed him from the band’s business holdings— is still set to be decided in arbitration.
Mars’ lawyer stated:
“Finally, somebody, somewhere told these guys they can’t bully Mick anymore.”
The band’s legal team claimed the ruling was a victory for them, saying they provided all required documents and that the lawsuit was now over.
Disputes Over Mick Mars’ Contributions to Mötley Crüe

As tensions grew, Mars revealed that he barely played on Mötley Crüe’s last three albums:
- ‘Generation Swine’ (1997): Mars claimed his parts were erased and replaced by others.
- ‘New Tattoo’ (2000): He said he was not invited to the writing process and only played one guitar lick.
- ‘Saints of Los Angeles’ (2008): Some of the guitar work was done by DJ Ashba, though Nikki Sixx admitted Mars was struggling with his parts.
Mötley Crüe denied some of these claims and insisted Mars played on the albums.
Mick Mars’ Solo Career

Mars focused on his solo music while fighting his legal battle. In February 2023, he started recording an album called ‘The Other Side of Mars’ in Los Angeles.
- The first single, ‘Loyal to the Lie,’ was released on October 31, 2023.
- The full album came out on February 23, 2024.
Mars had been planning a solo record since 2014, but the events with Mötley Crüe pushed him to finally release it.
What’s Next for Mötley Crüe?

Mötley Crüe continues touring with John 5 on guitar. Nikki Sixx and Vince Neil said they are working on new music and have more tour plans for 2025.
So, Mick Mars left Mötley Crüe due to severe health problems but expected to remain part of the band in some way. The band replaced him instead, and this led to a legal battle over finances, ownership, and legacy.
Mötley Crüe argues they had no choice, but Mars insists he was pushed out unfairly.
