Six Flags Magic Mountain X2: what's happening
In July 2026, two riders — Pamela Guillen and Naomi Greer-Wilkinson — reportedly suffered severe subdural hematomas (bleeding on the brain) requiring emergency brain surgery on X2, within a six-day span, following an earlier incident on July 5, 2026 in which LA County Fire responded to an unconscious rider. The ride has been closed to the public since July 12, 2026. In August 2026, the family of Christopher Hawley — who died in 2022 from a brain injury sustained on the same ride — settled their wrongful death lawsuit against Six Flags Magic Mountain and ride manufacturer S&S Worldwide, days before a scheduled Los Angeles County jury trial.

California's personal injury statute of limitations
California gives most injury victims two years from the date of injury to file a personal injury lawsuit, under California Code of Civil Procedure § 335.1.
Important exceptions: claims against a government entity (for example, a city- or state-owned facility) generally require a formal claim to be filed within six months of the injury — far shorter than the standard two-year window. Deadlines may also be extended in limited situations, such as when the injured person was a minor at the time of the injury. Because these exceptions are fact-specific and missing a deadline can permanently bar a claim, anyone considering a claim should confirm their specific deadline with an attorney rather than relying on the general rule alone.
