Maximilian Bowman purchased a used Tesla vehicle from a third-party dealership. The original owner of the car had previously sought and received repair services for a speaker defect under the manufacturer's warranty. Shortly after Bowman acquired the vehicle, the warranty expired before he raised any issues regarding the speaker. Bowman subsequently sued Tesla for breach of warranty under the Magnuson-Moss Warranty Act and the California Commercial Code. He argued that the original owner's right to sue for the breach was automatically assigned to him upon the sale of the car. The district court granted summary judgment in favor of Tesla, and Bowman appealed to the Ninth Circuit.
The Ninth Circuit reviewed the case de novo and affirmed the lower court's decision. The court addressed Bowman's central theory that the right to sue for the warranty breach was automatically assigned to him. Under California law, specifically California Civil Code section 954, a right of action may be assigned, but the assignor must manifest an intention to transfer the right. The court noted that Bowman conceded the original owner never expressly or intentionally assigned the claim to him. The court distinguished Bowman's reliance on Heritage Pacific Financial, LLC v. Monroy, explaining that case rejected the argument that the assignment of a promissory note automatically transferred fraud claims without evidence of intent to transfer. The court clarified that to the extent the original owner retains a claim against Tesla, that right may be asserted independently of continued ownership of the vehicle. Consequently, the right does not automatically flow to the new buyer by virtue of the purchase. The court concluded that Bowman's theory was merely an attempt to extend a warranty that had already expired.
This decision clarifies that used car buyers cannot rely on an automatic transfer of expired warranty claims from previous owners. Buyers must look to other legal mechanisms or specific contractual language to acquire such rights. The ruling reinforces that original owners retain the independent right to sue for warranty breaches even after selling the vehicle, but those rights do not pass to subsequent owners without a specific manifestation of intent to assign.
