EDWARD DIAZ et al., B339037

Plaintiffs and Appellants, (Los Angeles County Super. Ct. No. 23NWCV01867) v.

THOR MOTOR COACH, Inc., et al.,

Defendants and Respondents.

APPEAL from an order of the Superior Court of Los Angeles County. Olivia Rosales, Judge. Reversed. Law Firm of Lawrence Hutchens, Lawrence J. Hutchens; The Law Offices of Shay Dinata-Hanson, and Shay Dinata- Hanson for Plaintiffs and Appellants. Bravo Law Group, Dolores E. Gonzales, James R. Robertson; Horvitz & Levy, Shane H. McKenzie, and Lisa Perrochet for Defendants and Respondents. _________________________________ INTRODUCTION Plaintiffs Edward Diaz and Linda Diaz appeal from the trial court’s order staying their action under the Song-Beverly Consumer Warranty Act (Act) (Civ. Code, § 1790 et seq.), after the court enforced a forum selection clause contained in defendant Thor Motor Coach, Inc.’s (Thor) warranties that were issued when the Diazes bought one of the company’s motorhomes from a California dealer. The forum selection clause designated Indiana as the exclusive forum for any disputes relating to Thor’s express and implied warranties. In seeking to enforce the forum selection clause, Thor offered to stipulate that the Act would apply to the Diazes’ claims “as pled in their Complaint” and to not oppose an Indiana court applying the Act to the Diazes’ claims. Based on Thor’s offer, the trial court granted the motion to stay the Diazes’ action. We agree with two recent published decisions—Lathrop v. Thor Motor Coach, Inc. (2024) 105 Cal.App.5th 808, review granted January 15, 2025, S287893 (Lathrop) and Hardy v. Forest River, Inc. (2025) 108 Cal.App.5th 450, review granted April 30, 2025, S289309 (Hardy)—that held forum selection clauses like the one included in Thor’s warranties are unenforceable, even when they are accompanied by the type of stipulation Thor offered to make in this case, because such clauses are part of an illegal scheme of issuing warranties that violate the Act’s unwaivable statutory rights. We conclude the trial court erred when it enforced Thor’s forum selection clause. Accordingly, we reverse the trial court’s order granting Thor’s motion to stay.

2 BACKGROUND In 2021, the Diazes purchased a Thor motorhome from Giant RV for more than $400,000. The Diazes financed the purchase through U.S. Bank. When they purchased the motorhome, the Diazes signed a series of forms that were drafted by Thor, including a two-page document entitled, “Thor Motor Coach Product Warranty Registration Form” (Registration Form). By signing the Registration Form, the Diazes acknowledged that: (1) they “received, read and agreed to the terms and conditions of the Thor Motor Coach Limited Warranty and the Thor Motor Coach Structural Limited Warranty”; (2) they understood and agreed “to the forum selection clause and choice of law clause set forth in the Thor Motor Coach Limited Warranty and the Thor Motor Coach Structural Limited Warranty”; (3) that any actions related to their motorhome would be decided by a judge rather than a jury; and (4) that “exclusive jurisdiction for deciding legal disputes relating to alleged breach of warranty or representations of any nature rest[ed] in the courts within the state of manufacture, which is Indiana.” (Bolding and capitalization removed.) The limited warranties were included in a separate document entitled, “Warranty Guide,” which the Diazes were not required to sign. The Warranty Guide included a forum selection clause, designating Indiana—where Thor manufactured the motorhome—as the exclusive jurisdiction for litigation. The Warranty Guide also included a choice-of-law provision designating Indiana law as the law governing any disputes concerning the motorhome, and precluding application of any

3 conflict-of-law rule that would result in the application of another jurisdiction’s laws. In 2023, the Diazes sued Thor, Giant RV, and U.S. Bank (collectively, Thor), asserting a single cause of action under the Act. The Diazes alleged that Giant RV sold the motorhome with unspecified defects, and that Thor and its authorized repair facilities failed to repair those defects during the warranty period. The Diazes further alleged that Giant RV and Thor failed to refund their purchase of the motorhome or provide them a replacement motorhome. Thor moved to stay the Diazes’ action, arguing the forum selection clause included in the Registration Form and Warranty Guide required the Diazes to litigate their claims in Indiana. As part of its motion, Thor disclaimed the choice-of-law and jury- waiver clauses that were included in the Registration Form and Warranty Guide. Thor’s attorney submitted a declaration in support of the motion to stay, in which the attorney stated, “By this motion, Defendants THOR, GIANT RV and US BANK, stipulate (1) that the Song-Beverly Consumer Warranty Act will apply to Plaintiffs’ claims as [pleaded] in their Complaint; (2) that Defendants THOR, GIANT RV and US BANK will not oppose a request that the Indiana court utilize the Song-Beverly Consumer Warranty Act to adjudicate those allegations if permitted to go forward; and (3) that Plaintiffs’ right to a jury trial pursuant to California [Code of Civil Procedure] [section] 631[, subdivision] (a) will apply to Plaintiffs’ warranty claims pursued in an action against it in Indiana. Further, should Plaintiffs wish, Defendants THOR, GIANT RV and US BANK will enter into a written stipulation to that effect.” (Emphasis added.)

4 Thor also asserted in its motion to stay that, “[i]n the unlikely event the Indiana court refuses to honor the stipulation of THOR, GIANT RV and US BANK that plaintiffs’ claims against them are governed by Song-Beverly and/or plaintiffs’ right to a jury trial, plaintiffs can dismiss their complaint in Indiana and this court can dissolve the stay of this case and reassert jurisdiction over the dispute.” Thor stated that it “recognizes the California legislature made, with certain exceptions, a buyer’s rights under Song-Beverly essentially unwaivable. See, California [Civil Code] [sections] 1751 and 1790.1. Similarly, [Thor] does not dispute that pursuant to California [Code of Civil Procedure] [section] 631[, subdivision] (a), absent certain exceptions, that the ‘right to a trial by jury as declared by Section 16 of Article I of the California Constitution shall be preserved [to] the parties inviolate.’ ” The Diazes opposed Thor’s motion. They argued that the forum selection clause violated California’s public policy under the Act’s anti-waiver provision. The Diazes also argued that Thor could not waive application of the jury-waiver and choice-of- law clauses to make the forum selection clause enforceable because all the clauses must be read together. According to the Diazes, enforcement of the forum selection clause would be unreasonable because the choice-of-law clause violated the Act’s anti-waiver provision and California’s public policy. The Diazes further argued that Thor’s warranty provisions, including the forum selection clause, were unconscionable. The Diazes rejected Thor’s offer to stipulate not to oppose application of the Diazes’ California-specific rights in an Indiana forum. They claimed that “[b]y drafting and entering into warranty agreements that [Thor] know[s] contain illegal

5 provisions under California law, [Thor is] acting in bad faith and conducting an illegal scheme.” The trial court granted Thor’s motion to stay. The court ordered Thor to sign a stipulation “to not oppose” the application of California law in Indiana courts. The court further ordered that, should the Indiana courts decline to apply the Diazes’ rights under the Act, the Diazes could move to lift the trial court’s stay. The Diazes appealed.
