Toyota Financial Services (TFS) has begun notifying customers of a data breach discovered in early February 2025 that exposed sensitive personal information, including names and Social Security numbers.
Affected individuals were informed via letters mailed on May 1, nearly three months after the incident was first identified.
The breach was detected on February 7, 2025, when Toyota Financial Services learned that a “limited amount” of personal information had been inadvertently exposed. While the company has not publicly disclosed the root cause of the incident, the breach notification letter confirms that the exposed data includes sensitive personally identifiable information (PII). The scope of the exposure has not been quantified, but reports submitted to the Massachusetts Attorney General indicate that Social Security numbers were among the compromised data types.
Toyota Financial Services, which operates under Toyota Motor Credit Corporation and Toyota Motor Insurance Services, is a major provider of vehicle financing and leasing services across the U.S. The organization manages over $115 billion in assets and serves Toyota and Lexus customers, dealerships, and affiliates through its network. This breach marks the third known data security lapse involving Toyota’s financial services operations in less than 18 months.
In response to the breach, Toyota Financial Services launched an internal investigation and claims to have implemented new safeguards to prevent recurrence. Impacted customers are being offered 24 months of complimentary credit monitoring and identity protection services through Experian, with individualized activation codes provided in the notification letters.
As part of its breach notification, TFS provided guidance to consumers on how to place a security freeze on their credit reports, a protective measure that blocks third parties from accessing a credit file without authorization.
While the company characterizes the data exposure as “inadvertent,” no technical details or explanations have been offered regarding how the breach occurred or how long the data was exposed. This lack of transparency echoes previous incidents involving TFS, notably a June 2024 disclosure that customer information had been exposed due to an account-linking error originating in 2021. In that case, users were able to view data from unrelated accounts through the TFS website and mobile services.
Even more concerning is the December 2023 incident in which the Medusa ransomware group claimed responsibility for an attack on Toyota’s financial services in Europe and Africa, demanding $8 million in ransom and leaking sensitive data after the company reportedly refused to pay.
The recurrence of data exposure incidents at Toyota Financial Services raises concerns about the organization’s security posture. While credit monitoring services provide a buffer against potential misuse of compromised data, the series of incidents suggests systemic weaknesses.
