Opinion

SERGIO BETANCOURT, Case No. 22-cv-05898-RS Plaintiff, v. ORDER GRANTING DEFENDANT’S MERCEDES-BENZ USA, LLC, Defendant.

Sergio Betancourt is the owner of a 2015 Mercedes-Benz C300. In 2022, he presented the vehicle for repairs at a Mercedes-Benz service center in Ontario, California. The service center determined that the cylinder 1 engine piston was cracked, causing white smoke to billow out of the exhaust. Repair of the piston was not covered by the vehicle’s warranty. Betancourt filed this lawsuit, claiming that Mercedes-Benz was required to cover the cost of the repair under California’s Emission Control System Warranty Regulations (the “Warranty Regulations”). See Cal. Code Regs. tit. 13 § 2035–41. His lawsuit faces several fatal impediments. First, he seeks restitution, declaratory relief, and injunctive relief, but there are jurisdictional problems with all three remedies. As to restitution, Betancourt has not successfully averred that he lacks an adequate remedy at law, precluding equitable jurisdiction under principles of federal common law. See Sonner v. Premier Nutrition Corp., 971 F.3d 834, 844 (9th Cir. 2020). As to the two forms of prospective relief, Betancourt has not demonstrated that he faces the threat of an actual, imminent injury, so he lacks Article III standing. manufacturers to warrant “high-priced warranted parts” for seven years or 70,000 miles, whichever comes first. See id. § 2037(b)(3), (c). The piston falls outside the definition of a “warranted part” (and, a fortiori, outside the definition of a “high-priced warranted part”) because it is not “installed on a motor vehicle or motor vehicle engine.” Id. § 2035(c)(3)(B) (emphasis added). It is, instead, an integral part of the motor vehicle engine. Mercedes-Benz thus had no obligation to cover it under the warranty. For these reasons, and because the motion is granted on threshold jurisdictional issues, the grant of the motion is without prejudice. Sergio Betancourt owns a 2015 Mercedes-Benz C300. By January 28, 2022, Betancourt’s vehicle had amassed 51,672 miles, and it started experiencing problems. He brought it to the service center at Mercedes-Benz of Ontario in Ontario, California, where a crack in the engine’s piston was discovered. Repair of the piston was not covered by the vehicle’s warranty, so Betancourt paid several thousand dollars out-of-pocket for the repair. Betancourt sought reimbursement for the cost of the repair from Mercedes-Benz, but it maintained that the piston was not covered by the vehicle’s warranty and that the lack of coverage was consistent with California law. Betancourt then sued. On behalf of himself and a putative class of individuals who own vehicles subject to the same warranty, Betancourt averred that Mercedes-Benz’s warranty policy violated the Warranty Regulations, which require it to warrant certain high-priced parts for 7 years or 70,000 miles, whichever comes first. In Betancourt’s view, Mercedes-Benz’s failure to warrant its engine pistons violates the unlawful, unfair, and deceptive prongs of the California Unfair Competition Law, Cal. Bus. & Prof. Code §§ 17200, et seq. He seeks restitution of the costs paid for the repairs, an injunction requiring Mercedes-Benz to warrant engine pistons going forward, and a declaration stating that Mercedes-Benz’s ongoing failure to warrant the engine piston violates the Warranty Regulations. Mercedes-Benz has moved to dismiss. Its frontline position is that it was under no obligation to warrant the engine piston because it is not a “warranted part” within the meaning of the Warranty Regulations, much less “high-priced warranted part.” Should that argument fail, Mercedes-Benz offers plenty of backups. It contends that the complaint, despite sounding in fraud, fails to satisfy the heightened pleading requirements of Rule 9(b), that California’s consumer- protection laws should not be extended to out-of-state owners and lessees, and that its request for equitable relief is both too broad and disallowed by principles of federal equity jurisdiction. Mercedes-Benz moves to dismiss under Federal Rule of Civil Procedure 12(b)(6), which permits dismissal for “failure to state a claim upon which relief can be granted.” Fed. R. Civ. P. 12(b)(6). A Rule 12(b)(6) motion tests the legal sufficiency of the claims—that is, taking all the well-pleaded averments in the complaint as true and drawing all reasonable inferences in favor of the non-moving party, it “ask[s] whether the facts are sufficient to state a claim to relief that is plausible on its face.” Bodenburg v. Apple Inc., 146 F.4th 761, 767 (9th Cir. 2025). Though jurisdictional defects can be raised in a motion to dismiss, they may also be identified sua sponte by the district court. See Arbaugh v. Y&H Corp., 546 U.S. 500, 514 (2006) (“[C]ourts . . . have an independent obligation to determine whether subject-matter jurisdiction exists, even in the absence of a challenge from any party.”). A. Equitable Jurisdiction over Restitution Though Mercedes-Benz’s motion to dismiss focuses on the merits of Betancourt’s claim, it is necessary to begin with its argument that Betancourt has an adequate remedy at law. Betancourt has advanced only a claim under the UCL, which “provides only for equitable remedies.” Hodge v. Superior Ct., 145 Cal. App. 4th 278, 284, 51 Cal. Rptr. 3d 519, 523 (2006). Under principles of federal common law—which apply when, as here, a federal court is sitting in diversity—a plaintiff cannot obtain an equitable remedy if he has available an adequate remedy at law. See Sonner, 971 F.3d at 844. The availability of an adequate legal remedy—and thus the presence of federal equitable jurisdiction—is a threshold issue. See Guzman v. Polaris Industries Inc., 49 F.4th 1308, 1314 (9th Cir. 2022); Schlesinger v. Councilman, 420 U.S. 738, 753–54 (1975). As noted, Betancourt’s operative complaint seeks three forms of relief: restitution, injunctive relief, and declaratory relief. Betancourt is requesting restitution to cover the out-of- pocket expenses spent fixing the engine in his vehicle. Those expenses are perfectly recoverable through damages, which would put Betancourt back in the position he was in before Mercedes- Benz’s (alleged) violation—that is, with the money back in his wallet. Betancourt offers three reasons why damages are inadequate, but none work. First, he argues that damages and restitution are distinct remedies serving distinct purposes. The former seeks to compensate victims that are injured by a wrongdoer’s actions; the latter is intended to prevent the wrongdoer from profiting from his illegal acts. That is true, but it proves far too little. If the mere fact that two remedies have different objectives were enough to render the legal remedy inadequate, the inadequate remedy at law doctrine would be a nullity, for every remedy has a unique origin and objective. The dispositive question is whether in this case, damages suffice to remedy fully the harm for which the plaintiff seeks restitution. When the amount of money available under the two remedies is the same, the answer is yes. See Sonner, 971 F.3d at 844 (concluding that damages were adequate, and therefore that the plaintiff could not seek restitution under the UCL, where she sought the “same amount of money for the exact same harm”). The sum sought will both put the plaintiff in the position he would have been in absent the challenged conduct and prevent the defendant from profiting from that conduct, rendering resti
