Can dealer lie about credit approval?

I’ve been approved within the last year for the following -

  • Tier 1 BMW FS
  • Tier 1 Southeast Toyota FS
  • Tier 1 Honda FS

but now the dealer I am leasing a Hyundai from says I was not approved and need a co-signer. Can they be lying? Can I self submit the app on HMF website?

current Equifax is 774. Experian 708. Transunion 748.
I used the HMF website to check free credit and got 748.
