Bank trying to take repossession of vehicle for credit card debt

My nephew has a vehicle and a credit card through the same bank. He is 39 days late on his card. He said that they want the payment in full for him to keep his vehicle. They also said that if he doesn't allow them to take the vehicle they will continue to try to repossess it and he will be responsible for the repo fees. The credit card is less than $1,000. Can they take a car that is way more expensive? They are up to date on car payments. This is in Michigan.
