In this published opinion, the Second Appellate District, Division Five, invalidates an arbitration agreement which, among other things, eliminated the right to recover punitive damages:

To the extent the damage limitation clause applies to statutorily imposed remedies, such as punitive damages, it is “contrary to public policy and unlawful.” (Amendariz [v. Foundation Health Pscyhcare Services, Inc. (2000) 24 Cal.4th 83,] 104.)

So California plaintiffs have a right to seek punitive damages through arbitration, but questions remain about the application of federal due process standards to any such awards.
