Six Flags Magic Mountain in California is facing three lawsuits from riders who allege they suffered brain injuries after riding the X2 roller coaster.
More than 100 additional people have told attorneys that they intend to pursue claims alleging brain injuries after riding X2 during the past two years, according to lawyers representing the riders.
The claims follow a CNN investigation published last month, which identified more than a dozen reports of serious injuries and hospitalisations involving X2 riders over nearly two decades, including two deaths.
Dordick Law Corporation has filed three lawsuits alleging severe brain injuries on behalf of riders including 40-year-old Pamela Guillen and 26-year-old Naomi Greer-Wilkinson.
Guillen and Greer-Wilkinson both fell unconscious after riding X2 in July and underwent emergency surgery for brain injuries.
The third lawsuit was filed on behalf of lawyer Michael Wilk, who alleges that he suffered brain bleeding after riding X2 in February.
More than 100 additional clients have retained Dordick Law Corporation in connection with alleged injuries from X2, according to the firm.
The firm said it is "investigating the circumstances surrounding the alleged injuries and the mechanism by which the X2 ride is alleged to cause traumatic brain injury".

"Medical and engineering experts have prepared supporting materials addressing the alleged mechanism of injury," the firm added.
Via CNN, Six flags said it does not comment on pending litigation. According to a spokesperson, the X2 coaster was closed on 12 July.

At a news conference last week, Bulone said Six Flags "has been willingly gambling with people's lives". He added: "No ride like that should be allowed to exist."
"Magic Mountain has known about the dangers of this ride for years," said Dordick.
