ITEM 1117 OF REGULATION AB. (LEGAL PROCEEDINGS)

ITEM 1119 OF REGULATION AB. (AFFILIATIONS AND CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS)

AmeriCredit Financial Services Inc., the Sponsor and the servicer, is a Delaware corporation and is the originator of 100% of the
automobile loan contracts. The Sponsor purchases automobile loan contracts that are originated and assigned to it by automobile dealers and, to a lesser extent, third-party lenders and also originates automobile loan contracts directly with
consumers, either directly or through a wholly owned subsidiary. The Sponsor services all automobile loan contracts that it purchases or originates on behalf of the Issuing Entity, AmeriCredit Automobile Receivables Trust 2012-4, a Delaware
statutory trust.

The Sponsor sold and assigned the pool of initial automobile loan contracts to AFS SenSub Corp., the Depositor, a Nevada
corporation. The Depositor then sold the pool of sub-prime automobile loan contracts to the Issuing Entity and is the sole-owner of the certificate of the Issuing Entity.

General Motors Financial of Canada, Ltd., or GMF of Canada, is a wholly owned subsidiary of the Sponsor. GMF of Canada services a portion of the automobile loan contracts in the United
States on behalf of the Issuing Entity through its service center in Peterborough, Ontario. GMF of Canada utilizes the Sponsors standardized servicing policies and procedures and operates on the same single, unified and interconnected software
platform that the Sponsors other servicing centers utilize. GMF of Canada is managed by the same executive officers of the Sponsor that oversee the rest of the Sponsors operations, including servicing through its other servicing centers.
GMF of Canada is operated as a separate legal entity from the Sponsor due solely to the location of its servicing center in a foreign jurisdiction, despite being operated identically to the Sponsors other servicing centers and not as a
stand-alone entity (other than as is required for regulatory and corporate governance purposes).

The Servicer has complied, in all material respects, with the Applicable Servicing Criteria.

The Servicer separately confirmed with Wells Fargo Bank, National Association that none of the material instances of noncompliance
discussed in Exhibit 33.2 or the Schedules thereto relate to the transaction covered by the Form 10-K and that such material instances of noncompliance instead relate to residential mortgage-backed securities transactions, a wholly separate asset
class from this automobile loan contract asset-backed securities transaction. The Servicer determined that these instances of noncompliance that relate to other transactions in a distinct asset class do not represent material instances of
noncompliance with the servicing criteria relating to the transaction covered by the Form 10-K.
