Not applicable.

Substitute information provided in accordance with General Instruction J to Form 10-K:

Item 1112(b) of Regulation AB. Significant Obligors of Pool Assets (Financial Information).

There are no significant obligors with respect to the pool assets held by Ally Auto Receivables Trust 2012-4 (the “Issuing Entity”).

Item 1114(b)(2) of Regulation AB. Credit Enhancement and Other Support, Except for Certain Derivatives Instruments (Financial Information).

No entity or group of affiliated entities provides any external credit enhancement or other support with respect to either payment of the pool assets held by the Issuing Entity or payments on the notes (the “Notes”) or certificates (the “Certificates”) issued by the Issuing Entity.

Item 1115(b) of Regulation AB. Certain Derivatives Instruments (Financial Information).

No entity or group of affiliated entities provides any derivative instruments that are used to alter the payment characteristics of the cashflows from the Issuing Entity.

Item 1117 of Regulation AB. Legal Proceedings.

There are no current legal proceedings pending, or to the best knowledge of management of such entity, threatened, against the Issuing Entity, the sponsor, the servicer or the depositor that, if determined adversely to such party, would be expected to have a material adverse effect on the performance of the notes.

BNY Mellon Trust of Delaware, as Owner Trustee, has provided the following information for inclusion in this report on Form 10-K regarding The Bank of New York Mellon, which is an affiliate of the Owner Trustee that provides support services on behalf of the Owner Trustee in this transaction:

In the ordinary course of business, The Bank of New York Mellon is named as a defendant in or made a party to pending and potential legal actions. In connection with its role as trustee of certain RMBS transactions, The Bank of New York Mellon has been named as a defendant in a number of legal actions brought by RMBS investors. These lawsuits allege that the trustee had expansive duties under the governing agreements, including the duty to investigate and pursue breach of representation and warranty claims against other parties to the RMBS transactions. While it is inherently difficult to predict the eventual outcomes of pending actions, The Bank of New York Mellon denies liability and intends to defend the litigations vigorously.

Deutsche Bank Trust Company Americas (“DBTCA”), as Indenture Trustee, has provided the following information for inclusion in this report on Form 10-K:

DBTCA, the Indenture Trustee, has been named as a defendant in civil litigation concerning its role as trustee of certain residential mortgage backed securities (“RMBS”) trusts. On June 18, 2014, a group of investors (“Plaintiff Investors”) filed a civil action against DBTCA and Deutsche Bank National Trust Company (“DBNTC”) in New York State Supreme Court purportedly on behalf of and for the benefit of 544 private-label RMBS trusts asserting claims for alleged violations of the Trust Indenture Act of 1939, breach of contract, breach of fiduciary duty and negligence based on DBTCA’s and DBNTC’s alleged failure to perform their obligations as trustees for the trusts (the “NY Derivative Action”). An amended complaint was filed on July 16, 2014, adding Plaintiff Investors and RMBS trusts to the NY Derivative Action. On November 24, 2014, the Plaintiff Investors moved to voluntarily dismiss the NY Derivative Action without prejudice. Also on November 24, 2014, substantially the same group of Plaintiff Investors filed a civil action against DBTCA and DBNTC in the United States District Court for the Southern District of New York (the “SDNY Action”), making substantially the same allegations as the New York Derivative Action with respect to 564 RMBS trusts (542 of which were at issue in the NY Derivative Action). The SDNY Action is styled both as a derivative action on behalf of the named RMBS trusts and, in the alternative, as a putative class action on behalf of holders of RMBS representing interests in those RMBS trusts. On January 19, 2016, the court overseeing the SDNY Action granted in part the defendants’ motion to dismiss on procedural grounds: as to the 500 trusts that are governed by pooling and servicing agreements, the court declined to exercise jurisdiction. The court did not rule on substantive defenses asserted in defendants’ motion to dismiss. The court further ordered plaintiffs to file an amended

complaint consistent with its ruling as to the remaining 64 trusts governed by indentures. The defendants will have an opportunity to file new defensive motions with respect to the amended complaint after it is filed. DBTCA will continue to vigorously defend the SDNY Action. On December 30, 2015, IKB International, S.A. and IKB Deutsche Industriebank A.G. filed a Summons With Notice in New York state court naming as defendants DBNTC and DBTCA, as trustees of 37 RMBS trusts (the “IKB Action”). The claims in the IKB Action appear to be substantively similar to the SDNY Action. The IKB Action is not styled as a putative class action, but may attempt to bring derivative claims on behalf of the named RMBS trusts. DBTCA intends to vigorously defend the IKB Action. DBTCA has no pending legal proceedings (including, based on DBTCA’s present evaluation, the litigation disclosed in this paragraph) that would materially affect its ability to perform its duties as Indenture Trustee on behalf of the Noteholders.

Part II

Item 9B. Other Information

None.

Part III

Substitute information provided in accordance with General Instruction J to Form 10-K:

Item 1119 of Regulation AB. Affiliations and Certain Relationships and Related Transactions.

Information required by Item 1119 of Regulation AB has been omitted from this report on Form 10-K in reliance on the Instruction to Item 1119. The information has been provided previously in a Prospectus, dated August 7, 2012, filed by the Issuing Entity, pursuant to Rule 424(b)(5) of the Securities Act of 1933 on August 9, 2012.

Item 1122 of Regulation AB. Compliance with Applicable Servicing Criteria.

Each of Ally Financial Inc. (“Ally Financial”) and Deutsche Bank Trust Company Americas (each, a “Servicing Participant”) has been identified by the registrant as a party participating in the servicing function with respect to the pool assets held by the Issuing Entity during the reporting period. Each of the Servicing Participants has completed a report on an assessment of compliance with the servicing criteria applicable to such Servicing Participant (each, a “Report on Assessment”) during the Issuing Entity’s year ended December 31, 2015, which Reports on Assessment are attached as exhibits to this Form 10-K. In addition, each of the Servicing Participants has provided an attestation report (each, an “Attestation Report”) by a registered independent public accounting firm regarding its related Report on Assessment. Each Attestation Report is attached as an exhibit to this Form 10-K.

None of the Reports on Assessment or the related Attestation Reports has identified any material instances of noncompliance with the servicing criteria described in the related Report on Assessment as being applicable to each such Servicing Participant.

Item 1123 of Regulation AB. Servicer Compliance Statement.

Ally Financial has been identified as the servicer during the reporting period with respect to the pool assets held by the Issuing Entity. Ally Financial has provided a statement of compliance with the applicable servicing activities (the “Compliance Statement”), signed by an authorized officer, and such Compliance Statement is attached as an exhibit to this Form 10-K.
