Court of Appeal, Second Appellate District, Division Eight
The Rule of Diaz v. Thor Motor Coach is that forum selection clauses in motorhome warranties are unenforceable as unconscionable when they are part of warranty agreements containing other illegal provisions that violate California's Song-Beverly Consumer Warranty Act, even when the manufacturer offers to stipulate not to enforce the illegal provisions in the out-of-state forum.
