As many as 2.5 million GM Financial customers were thrust into a state of uncertainty from January through May after the lender stopped reporting payment information to the credit bureaus.
Problems after a systemwide technology upgrade in late December prompted the captive to stop reporting the data, a move that saved some past-due customers from the repercussions of tardiness exceeding 30 days but put those applying for other loans in limbo.
GM Financial says by the end of this month, reporting for all affected customers will be up to speed.
The upgrade was necessary, Bob Beatty, executive vice president of customer experience, told Automotive News in January.
"Our systems couldn't support our future plans as far as various product offerings and service capability," he said. "Frankly, we didn't have the capacity to grow to the size we expect to grow to in the coming years."
The upgrade involved consolidating four systems that contained customer accounts. While servicing problems resulting from the upgrade were expected, the scope of those difficulties was not.
