Santander Consumer USA

As the company boosts originations to subprime and other borrowers, it remains to be seen if the improvements in asset quality will continue. A similar question mark is hanging over many consumer lenders these days.

The largest U.S. labor federation is calling on Santander Consumer USA to end its practice of allowing car dealers to add interest to a vehicle loan unrelated to the borrower's creditworthiness.

The subprime lender could lose a big partner now that Fiat Chrysler has officially announced it will form its own auto finance unit, and the two are negotiating an end to their 6-year-old relationship.

The subprime auto lender paid $2.9 million to Connecticut consumers and a $100,000 fine for miscalculating balances owed on repossessed cars and for charging improper fees. It says the settlement is part of an effort to clean up "legacy issues."

The subprime auto lender late Friday provided the final details of its separation agreement with Thomas Dundon, who stepped down two years ago in a leadership shake-up.
