The California Court of Appeal recently ruled in the case of Kostandian v. American Honda Motor Co., Inc. (B345489), compelling arbitration in a dispute involving a leased vehicle. The court's decision reverses a lower court's order that had denied American Honda and Standard Motor's motion to compel arbitration. This ruling affects consumers who enter into arbitration agreements when leasing vehicles and may set a precedent for future cases involving similar disputes.
The case began when David Kostandian filed a lawsuit against American Honda Motor Co. and Standard Motor, LLC, in November 2024. Kostandian claimed that his leased 2024 Acura Integra had several defects, leading him to assert nine causes of action, including tort and warranty claims. He alleged that despite bringing the vehicle to an authorized repair facility five times, it could not be repaired. Kostandian also stated that he revoked acceptance of the vehicle in writing due to these defects, but the companies did not respond adequately to his demands for remedies.
The dispute centers around arbitration agreements included in both the lease agreement and the warranty booklet for the vehicle. Kostandian's lease contained a provision stating that any disputes between him and the companies could be resolved through arbitration rather than in court. Additionally, the warranty booklet also included an arbitration agreement, which specified that disputes related to the vehicle would be handled through arbitration.
In February 2025, American Honda and Standard Motor filed a motion to compel Kostandian to submit his claims to arbitration, arguing that both the lease and warranty agreements contained valid arbitration provisions. They claimed that Standard Motor, as the lessor, was entitled to enforce the arbitration provision in the lease, and that American Honda could enforce the warranty booklet's arbitration agreement. However, Kostandian opposed the motion, arguing that the agreements were unconscionable and that his claims fell outside the scope of the arbitration clauses.
In May 2025, the trial court denied the motion to compel arbitration, concluding that the companies had not demonstrated the existence of a binding and enforceable arbitration agreement. The court found that there was insufficient evidence to prove that Standard Motor was doing business as Acura of Los Angeles Westside, the name under which the lease was signed. Additionally, the court ruled that American Honda could not enforce the lease's arbitration provision because its subsidiary was not a signatory to the agreement.
On appeal, the California Court of Appeal reversed the trial court's decision. The court ruled that American Honda and Standard Motor had met their burden of establishing the existence of the arbitration agreements. The court stated, "The burden therefore shifted to respondent to dispute the existence of an arbitration agreement as to Standard Motor." The court emphasized that Kostandian had not presented evidence disputing the existence of the agreements.
The court also addressed the warranty booklet's arbitration agreement, stating that Kostandian had not disputed the existence of this agreement either. The court found that the arbitration agreement was valid and enforceable, noting that Kostandian had signed a document confirming receipt of the warranty information. The court concluded that Kostandian was bound by the arbitration provisions in both the lease and the warranty booklet.
This ruling has significant implications for consumers and companies alike. It reinforces the enforceability of arbitration agreements in consumer contracts, particularly in cases involving vehicle leases and warranties. The court's decision may encourage companies to include arbitration clauses in their agreements, knowing that they are likely to be upheld in court.
Moving forward, the ruling sets a clear precedent regarding the enforcement of arbitration agreements in similar cases. It highlights the importance of consumers understanding the implications of signing such agreements and the potential limitations on their ability to pursue claims in court. As for Kostandian, the case will now proceed to arbitration as directed by the court.
Details were not available in the court filing regarding whether Kostandian plans to appeal the decision or if there are any related cases pending. However, the ruling emphasizes the need for consumers to be aware of the terms of their agreements when entering into contracts that include arbitration clauses.
