X. CREDIT RISK RETENTION

On the Closing Date, Santander Consumer or another wholly-owned special purpose subsidiary of Santander Consumer retained a portion of the aggregate Percentage Interests of the Certificates in order to satisfy the obligations of Santander Consumer under the requirements of the SEC’s credit risk retention rules 17 C.F.R. Part 246 (“Regulation RR”), as in effect and applicable on the Closing Date. The portion of the Certificates being retained to satisfy the requirements of Regulation RR is referred to herein as the “Retained Interest.” As of the last day of the period covered by this report the depositor or another wholly-owned special purpose subsidiary of Santander Consumer continues to retain the Retained Interest in accordance with Regulation RR.

The depositor and its affiliates pledge retained securities as collateral for loans, repurchase agreements or other financing transactions from time to time. However, Santander Consumer has not transferred or hedged the Retained Interest except as permitted under Regulation RR.

Santander Consumer has not changed the manner in which it retains the Retained Interest, except in accordance with Regulation RR.

The arrangements described above in relation to Regulation RR have not been structured with the objective of enabling or facilitating compliance by any person with any requirement of Regulation (EU) 2017/2402 of December 12, 2017, as amended or of Regulation (EU) 2017/2402, as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended).

There was no material change in Santander Consumer’s, or an affiliate of Santander Consumer’s, interest in any securities issued by the issuer resulting from the purchase, sale or other acquisition or disposition of securities between the Closing Date and the last day of the period covered by this report.

No assets securitized by Santander Consumer USA Inc. (the “Securitizer”) and held by Santander Drive Auto Receivables Trust 2023-6 were the subject of a demand to repurchase or replace for breach of the representations and warranties during the current monthly distribution period.
