Did dealer lie about tax credit?

Bought a 2022 euv in august for $25.1, minus $4k for point of sale transferred credit. But, I just got a letter from the IRS requesting me to fill out a form relating to the transfer. The dealer assured me that because of how they were applying, our income didn't matter. But based upon what I'm reading, we're over the limit and will owe those $4000 back. Buyer beware, I understand. But did this guy just straight up lie to me?
