My bank knowingly let me purchase a car with frame damage, how can i get out of the loan?

I purchased a vehicle in August, and the bank I went through apparently knowingly let me purchase the vehicle knowing that it had frame damage. I just recently got a car fax report done on it. When I was reading the report there were alot of other really shady things about it, like the fact that 1 owner had the vehicle for 3 years and put 58,968 miles on it, the 2nd owner got the car in 2005 and according to the carfax report they had it for 7 months and when it was auctioned off it had 59,076 which is what I purchased it with on the odometer, this sounds really fishy to me like the dealer may have played with the odometer, the report also states the vehicle was in an accident and suffered severe frame damage, that shouldve shown up and threw a red flag to the loan company, thus the reason I think they did some shady stuff to basically get my money for a damaged car.
