Car loan denied ??

I purchased a car 7 months ago but I got a letter like 2 months in. Stating the loan/ lender ? That the dealer works with denied my car loan. Then my insurance also told me they didn’t have info for my car lender so idk I just ignored it and continue paying the dealer and they’ve been accepting my car payments but never contacted me about that. I kinda want to call and ask who is my lender but I’m scared lol what should I expect? This is my first time purchasing a new car are they going to take my car or how does this even work?
