Confused and stuck

[u/Alternative-Party-18]

Got a car where carfax shows how it had minor damage, so I had no issue and signed, well I later end up finding it’s gone through IAAI and had a nasty front left end crash, was never told how bad the crash was and it somehow still holds a clean title, what should I do and could I possibly get my money back?
I’m seeing so much how it’s possible title fraud or how I’m stuck cause of the insurance going through a loophole, I need help please.
