ITEM 1117 OF REGULATION AB. (LEGAL PROCEEDINGS)

As
a consumer finance company, the sponsor is subject to various consumer claims and litigation seeking damages and statutory penalties, based upon, among other things, usury, disclosure inaccuracies, wrongful repossession, violations of bankruptcy
stay provisions, certificate of title disputes, fraud, breach of contract and discriminatory treatment of credit applicants. Some litigation against the sponsor could take the form of class action complaints by consumers and certain legal actions
include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages.

In July 2014, in connection with an
investigation by the U.S. Department of Justice in contemplation of a civil proceeding for potential violations of the Financial Institutions Reform, Recovery, and Enforcement Act of 1989, General Motors Financial Company, Inc. (General Motors
Financial), immediate parent of the sponsor, was served with a subpoena by the U.S. Department of Justice directing it to produce certain documents relating to its and its subsidiaries and affiliates origination and securitization
of subprime automobile loans since 2007. Among other matters, the subpoena requests information relating to the underwriting criteria used to originate these automobile loans and the representations and warranties relating to those underwriting
criteria that were made in connection with the securitization of the automobile loans. General Motors Financial has subsequently been served with additional investigative subpoenas to produce documents from state attorneys general and other
governmental offices relating to its retail auto loan business and securitization of auto loans. In October 2014, General Motors Financial received a document request from the Securities and Exchange Commission in connection with its investigation
into certain practices in subprime auto loan securitization. These investigations are ongoing and could in the future result in the imposition of damages, fines or civil or criminal claims and/or penalties.

No assurance can be given that the ultimate outcome of the investigations or any resulting proceedings would not materially and adversely affect General
Motors Financial or any of its subsidiaries and affiliates, including the servicer, or the interests of the noteholders or the servicers ability to perform its duties under the transaction documents.

On June 18, 2014, a civil action was filed against Citibank in the Supreme Court of the State of New York by a group of investors in 48 private-label
RMBS trusts for which Citibank allegedly serves or did serve as trustee, asserting claims for purported violations of the Trust Indenture Act of 1939, breach of contract, breach of fiduciary duty and negligence based upon Citibanks alleged
failure to perform its duties as trustee for the 48 RMBS trusts. On November 24, 2014, plaintiffs sought leave to withdraw this action. On the same day, a smaller subset of similar plaintiff investors in 27 private-labeled RMBS trusts for which
Citibank allegedly serves or did serve as trustee, filed a new civil action against Citibank in the United States District Court for the Southern District of New York asserting similar claims as the prior action filed in state court. In January
2015, the court closed plaintiffs original state court action. Citibanks motion to dismiss the federal complaint was fully briefed as of May 13, 2015. On September 8, 2015, the federal court dismissed all claims as to 24 of the
27 trusts and allowed certain of the claims to proceed as to the other three trusts. That case, involving the three remaining trusts, is pending.



---

On November 24, 2015, the same investors that brought the federal case brought a new civil action in the
Supreme Court of the State of New York related to 25 private-label RMBS trusts for which Citibank allegedly serves or did serve as trustee. This case includes the 24 trusts previously dismissed in the federal action, and one additional trust. The
investors assert claims for breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts of interest and violation of New Yorks Streit Act. Citibank filed a motion to dismiss this case on February 26, 2016.

On August 19, 2015, the Federal Deposit Insurance Corporation (the FDIC) as Receiver for a financial institution filed a civil action against
Citibank in the Southern District of New York. This action relates to one private-label RMBS trust for which Citibank formerly served as trustee. FDIC asserts claims for breach of contract, violation of the Streit Act and violation of the Trust
Indenture Act. Citibank is jointly briefing a motion to dismiss with The Bank of New York Mellon and U.S. Bank, entities that have also been sued by FDIC in their capacity as trustee.

There can be no assurances as to the outcomes of litigation or the possible impact of litigation on Citibank related to its RMBS trusts. However, Citibank
denies liability and continues to vigorously defend against these litigations. Furthermore, neither the above-disclosed litigation nor any other pending legal proceeding involving Citibank will materially affect Citibanks ability to perform
its duties as Trustee under the Indenture for this ABS transaction.
