Ladies and Gentlemen:

In connection with the registration under the Securities Act of 1933 (the “Act”), of (a)(i) $1,250,000,000 aggregate principal amount of 6.750% Fixed Rate Notes due 2031, and (ii) $1,250,000,000 aggregate principal amount of 7.400% Fixed Rate Notes due 2036 (collectively, the “Securities”) of Stellantis Finance US Inc., a Delaware corporation (“Stellantis Finance”), and (b) the related guarantees (the “Guarantees”) of the Securities by Stellantis N.V., a public limited liability company incorporated under the laws of The Netherlands (“Stellantis”), issued pursuant to the Indenture, dated as of September 16, 2026, by and among Stellantis Finance, Stellantis and The Bank of New York Mellon, as Trustee (the “Indenture”), we, as your United States counsel, have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion.

Upon the basis of such examination, it is our opinion that (1) the Securities constitute valid and legally binding obligations of Stellantis Finance, and (2) assuming the Guarantees have been duly authorized, executed and delivered by Stellantis insofar as the laws of The Netherlands are concerned, the Guarantees constitute valid and legally binding obligations of Stellantis, subject, in each case, to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.
