GM also owns nearly a 10 percent stake in Ally.
In the third quarter Ally made a $384 million net profit, reversing a loss from a year ago mainly because it didn't have losses from ResCap.
Ally said its global automotive services business continues to be strong, with the loans it financed increasing and improving during the third quarter, despite increased competition among lenders for automotive loans.
Meanwhile, retail deposits at its Ally Bank division increased by 22 percent, and customer accounts grew by 24 percent, the company said.
In October Ally repaid $2.9 billion of the debt it issued under a government program that backed hundreds of billions of dollars in U.S. bank debt during the financial crisis. The program is separate from the bailout. Ally said last month that it plans to repay in December the remaining $4.5 billion guaranteed under the Federal Deposit Insurance Corp. program.
