You might automatically assume if student loans — and difficulty in maintaining payments — are the hurdles to keeping the financing from being finalized for vehicle delivery, the customer surely is a recent college graduate.

A new report from the Consumer Financial Protection Bureau indicated that situation might not necessarily be the case.

The CFPB released a report that examined complaints from older student loan borrowers about servicing practices that can jeopardize their long-term financial security.

In the last decade, bureau officials found the number of older student loan borrowers has quadrupled and the amount of debt per older borrower has roughly doubled, as many take out loans for children or grandchildren.

According to the report, older borrowers struggling to make payments complain about obstacles to enrolling in income-driven payment plans and accessing their protections as cosigners. In 2015, nearly 40 percent of federal student loan borrowers age 65 and older were in default.

“It is alarming that older Americans are the fastest growing segment of student loan borrowers,” CFPB director Richard Cordray said. “Many of these older Americans are helping to finance their children’s or grandchildren’s education while living on a fixed income.

“We are concerned that student loans are contributing to financial insecurity for many older Americans and that student loan servicing problems can add to their distress,” Cordray continued.

The CFPB calculated student loans make up the nation’s second-largest consumer debt market, and seniors are the fastest growing segment of this market.

From 2005 to 2015, the number of Americans age 60 or older with one or more student loans quadrupled from about 700,000 to 2.8 million, and average debt load owed by an older borrower roughly doubled from $12,000 to $23,500.

The CFPB’s analysis of survey data showed that about three-in-four older borrowers with student loans used them to finance their children’s or grandchildren’s college education.
