Exhibit 33.1

Managements Assessment of Compliance with SEC Regulation AB Servicing Criteria



|1. | Management of Santander Consumer USA Inc. (SC) is responsible for assessing compliance with the
servicing criteria applicable to it under paragraph (d) of Item 1122 of Regulation AB as of and for the year ended December 31, 2018. The transactions covered by this report are all publicly registered transactions backed by auto loans for
which Santander Consumer USA Inc. is the servicer (the Platform). See Appendix A.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | SCs management has assessed SCs compliance with the applicable servicing criteria as of and for the
year ended December 31, 2018. In making this assessment, management used the criteria set forth in paragraph (d) of Item 1122 of Regulation AB (See Appendix B), except for the following criteria which SC determined are not applicable to
the activities performed by SC or through its vendors with respect to the Platform: 1122(d)(1)(iv), 1122(d)(2)(iii), 1122(d)(2)(vi), 1122(d)(4)(ix), 1122(d)(4)(x), 1122(d)(4)(xi), 1122(d)(4)(xii), and 1122(d)(4)(xiii).
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | There were no external enhancements as of and for the year ended December 31, 2018, with respect to the
Platform taken as a whole.
|-- | ----------------------------------------------------------------------------------------------------------------------------------



|4. | With respect to servicing criterion, Item 1122(d)(1)(iii), some of the transactions included in the Platform
require the Company to utilize a backup servicer when certain events, which are specified within the transaction agreements, occur. As of and for the year ended December 31, 2018, the events that would require a backup servicer as listed in the
transaction documents did not occur, and therefore the requirement for a backup servicer does not apply.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5. | SC has engaged vendors that are not servicers as defined in Item 1101(j) of Regulation AB to perform limited or
scripted activities with respect to the servicing criteria applicable to each vendors activities as set forth in Appendix B of this report. SC elected to take responsibility for assessing compliance with the portion of the servicing criteria
applicable to each such vendor. SC has policies and procedures in place to provide reasonable assurance that the vendors activities comply in all material respects with the portion of the servicing criteria applicable to each vendor. SCs
management is solely responsible for determining that it meets the requirements to apply Interpretation 200.06 of the SEC Compliance and Disclosure Interpretations.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. | SC has complied, in all material respects, with the applicable servicing criteria for which it is responsible,
as of and for the year ended December 31, 2018, with respect to the Platform taken as a whole.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. | SCs management has not identified and is not aware of any material instance of noncompliance by the
vendors with regard to the applicable servicing criteria, as of and for the year ended December 31, 2018, with respect to the Platform taken as a whole.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. | SCs management has not identified any material deficiency in its policies and procedures to monitor the
compliance by the vendors with the applicable servicing criteria, as of and for the year ended December 31, 2018, with respect to the Platform taken as a whole.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | PricewaterhouseCoopers LLP, an independent registered public accounting firm, has issued an attestation report
on SCs compliance with the applicable servicing criteria as of and for the year ended December 31, 2018.
