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.

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

Each of Santander Consumer USA Inc. (the Servicer) and Wells Fargo Bank, National Association (each, a Servicing
Participant) have been identified by the issuing entity as parties participating in the servicing function with respect to the pool assets held by the issuing entity. Each of the Servicing Participants has completed a report on an
assessment of compliance with the servicing criteria applicable to it (each, a Report on Assessment), 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 one or more registered public accounting firms, which reports are also attached as exhibits to this Form 10-K.

With respect to servicing criteria 1122(d)(3)(i)(B), certain reports to investors provided information that was not calculated in accordance
with the terms specified in the transaction agreements. Forms 10-D/A were filed on September 13, 2012 and on February 28, 2013 to accurately reflect information calculated in accordance the terms of the transaction agreements. Neither the
timing nor the amount of principal or interest payable to Noteholders was impacted by the adjustments.

The Report on Assessment of Wells
Fargo Bank, National Association (the Indenture Trustee) and the Attestation Report related to the Indenture Trustee disclosed the following material noncompliance with servicing criteria 1122(d)(3)(i)(B) and 1122(d)(3)(ii), as
applicable to the Indenture Trustee during the twelve months ended December 31, 2012: (a) with respect to servicing criterion 1122(d)(3)(i)(B), certain reports to investors did not provide information calculated in accordance with the
terms specified in the transaction agreements; and (b) with respect to servicing criterion 1122(d)(3)(ii), certain amounts due to investors were not allocated and remitted in accordance with timeframes, distribution priority and other terms set
forth in the transaction agreements. The Indenture Trustee has confirmed to Santander Drive Auto Receivables Trust 2010-1 (the Issuer) that these errors did not involve the Issuer or investors in the Issuer. We have not independently
verified the accuracy of the Indenture Trustees assertions, the adequacy of its remediation efforts or the accuracy of such confirmation.

The Report on Assessment of the Servicer and the Attestation Report related to the Servicer
disclosed the following material noncompliance with servicing criteria 1122(d)(3)(i)(C) applicable to the Servicer during the year ended December 31, 2012: the Servicer inappropriately excluded criterion 1122(d)(4)(ii) from Managements
Report on Assessment of Compliance with Servicing Criteria dated March 25, 2013. The failure of the Servicer to include criterion 1122(d)(4)(ii) as an applicable criterion caused certain material outsourced vendors, which are each
not considered a servicer as defined under Item 1101(j) of Regulation AB, to be excluded from testing of 1122(d)(1)(ii) within the Regulation AB Attestation Report dated March 25, 2013.

As described in Report on Assessment of the Servicer and the Attestation Report related to the Servicer, for servicing criteria 1122(d)(2)(i),
1122(d)(4)(i), 1122(d)(4)(ii), 1122(d)(4)(iv), and 1122(d)(4)(viii), the Servicer has engaged certain vendors to perform certain activities required by this servicing criteria. The Servicer has determined that these material outsourced vendors are
not considered a servicer as defined in Item 1101(j) of Regulation AB, and the Servicer has elected to take responsibility for assessing compliance with the servicing criteria applicable to these vendors as permitted by
Interpretation 17.06 of the SEC Division of Corporation Finance Manual of Publicly Available Telephone Interpretations (Interpretation 17.06). As permitted by Interpretation 17.06, the Servicer has asserted that it has policies and procedures in
place designed to provide reasonable assurance that the vendors activities comply in all material respects with the servicing criteria applicable to this vendor.

Item 1122(d)(4)(ii) was marked as not applicable in the Servicers managements assessment of compliance in error. The Servicer
confirms that Item 1122(d)(4)(ii) is applicable to the Servicer. The omission of testing for compliance by the Servicer with Item 1122(d)(4)(ii) has since been addressed and the Servicer confirms that the pool assets and related documents,
at all times during the fiscal year ended December 31, 2012, were held in accordance with the terms of the transaction agreements. Consequently, the failure of the Servicer to take responsibility for Item 1122(d)(4)(ii) in its
managements assessment of compliance as filed on March 29, 2013, had no impact on investors.

During the fiscal year ended
December 31, 2012, the Servicer had, and continues to have, in place practices and procedures to ensure the safekeeping of receivables files in accordance with Item 1122(d)(4)(ii). The Servicer maintains multiple levels of safekeeping and
tracking of its documents and records.

Every receivable is recorded as a data record into the Servicers loan origination, loan
servicing and imaging systems. At the time of origination, such systems indicate the status of the certificate of title as pending until the perfected security interest has been confirmed by the relevant state department of motor vehicles at which
time the system is updated to reflect the location of the certificate of title. Such systems identify for each receivable the locations of the applicable receivables file and certificate of title and, where applicable, the identity of any vendor
holding physical possession of those items on behalf of SCUSA. The Servicer records, stores and backs up all electronic data and images associated with each receivable. If a receivable file is recalled for any reason from a location, this change in
location is reflected in the system.

The Servicer maintains oversight policies and procedures for its vendors. As part of the
Servicers vendor oversight activities, the Servicer makes periodic site visits to vendor locations to confirm compliance by vendors with their obligations to the Servicer to maintain the safekeeping of documents. The effectiveness of these
policies and procedures is further confirmed by SCUSAs ability to regularly obtain receivables files and certificates of title from its vendors in the ordinary course of business. In addition, the Servicer monitors key performance indicators
at each vendor to track performance levels and implements corrective measures as appropriate. To mitigate the need for corrective action, the Servicer communicates such performance indicators to its vendors on a regular basis to help ensure
alignment between such indicators and the performance by the vendor.

In connection with the filing of this 10-K/A, the Servicer performed
a review of the foregoing policies and procedures and confirmed that such policies and procedures were in place for the fiscal year ended December 31, 2012. Further, in addition to the regular oversight and analysis of internal and vendor
operations as it relates to the safekeeping of documents, the Servicer engaged its auditors to test its policies and procedures for the safekeeping of receivable files in accordance with Item 1122(d)(4)(ii) and was found to be in compliance for
the fiscal year ended December 31, 2012.

Going forward, a qualified Servicer manager will confirm each year that all required items have
been addressed in the managements assessment of compliance.

Item 1123 of Regulation AB. Servicer Compliance Statements.

The Servicer has been identified by the issuing entity as the servicer with respect to the asset pool held by the issuing
entity. The Servicer has completed a statement of compliance with applicable servicing criteria (a Compliance Statement) signed by an authorized officer of the Servicer. The Compliance Statement is attached as an exhibit to
this Form 10-K.
