Ally Financial data breach class action lawsuit overview:
- Who: Plaintiff Robert Hamilton filed a class action lawsuit against Ally Financial Inc., Ally Bank and Financial Business and Consumer Solutions Inc.
- Why: Hamilton claims Ally Financial failed to properly safeguard the personally identifiable information of 4.2 million of its customers during an April 2024 data breach.
- Where: The class action lawsuit was filed in a Pennsylvania federal court.
Ally Financial failed to properly secure and safeguard the personally identifiable information (PII) of more than 4.2 million customers during an April 2024 data breach, a new class action lawsuit alleges.
Plaintiff Robert Hamilton argues that mismanagement by Ally Financial and its debt collection agency, Financial Business and Consumer Solutions Inc. (FBCS), allowed the PII of Ally Financial customers to become exposed after FBCS experienced a data breach.
“Defendants failed to adequately protect Plaintiff’s and Class Members’ PII –– and failed to even encrypt or redact this highly sensitive information,” the Ally Financial class action states.
Hamilton wants to represent a nationwide class of consumers whose PII was compromised in the Ally Financial data breach.
Class action claims PII exposed in data breach was unencrypted
Hamilton argues Ally Financial and FBCS failed to adequately protect the PII of Ally customers by failing to vet its vendors to ensure they were submitting PII to an entity with adequate data security practices.
“Defendants disregarded the rights of Plaintiff and Class Members by intentionally, willfully, recklessly or negligently failing to ensure that FBCS had adequate and reasonable safeguards and measures in place to protect the PII of Plaintiff and Class Members after that information was transferred and entrusted to FBCS,” the Ally Financial class action lawsuit says.
Hamilton claims Ally Financial and FBCS are guilty of negligence, negligence per se, breach of express contract, breach of implied contract and unjust enrichment.
The plaintiff demands a jury trial and requests declaratory and injunctive relief and an award of actual, compensatory, statutory, nominal and punitive damages for himself and all class members.
A consumer filed a separate class action lawsuit against Ally Financial in 2024 over claims the company breached its duty with military servicemembers by failing to allow them to terminate their motor vehicle leases.

534 thoughts onAlly Financial class action claims data breach exposed 4.2M customers’ PII
Today (August 14, 2025), I received a couple of calls claiming to be from Ally’s Fraud Department, and I assume they have my info from the breach. One of the numbers showed “Ally Financial” as the caller ID. The caller numbers were 757-247-2559 and 757-917-2559 which are similar to the fraud department’s number, but NOT the same. They claimed there were 3 large transactions that they wanted to verify weren’t mine. When I called the first number back it sounded like Ally banking prompts, so it’s a sophisticated scam. The caller kept talking over me though, and when I said it sounded like a scam and that I would call the bank directly to verify, he said I could Google the number which a real representative would not have been so aggressive. I didn’t give out my info but just want to put this out there in case anyone else gets similar calls because it’s easy to get caught off guard and feel rushed when you hear “fraud”. You can always hang up and call your bank to verify.
