Captive finance companies are recovering some of the business they lost to large banks during the credit squeeze last year.
Among the top 10 lenders, automakers' finance arms accounted for about 28 percent of new-and used-vehicle loans and leases in the second quarter, according to Experian's AutoCount. A year earlier, the figure was 18.5 percent.
Much of the increase came through aggressive leasing programs. Toyota Financial Services also was especially active writing used-vehicle loans.
Toyota Financial rose to the top of the rankings, which are based on market share data culled from vehicle registrations. It posted an 8.2 percent share, ahead of Chase Auto Finance, No. 1 in the second quarter of 2009.
American Honda Finance Corp. ranked No. 4, passing up Wells Fargo Dealer Services, formerly Wachovia Dealer Services, which ranked third a year earlier.
GMAC Financial Services, now Ally Financial Inc., is still counted as a captive finance company in the rankings even though it became a bank holding company in December 2008. Although GMAC's share nosedived early last year as General Motors veered towards bankruptcy, it slowly climbed to fifth place by the end of 2009 and took the No. 2 spot behind Toyota Financial in the second quarter of this year.
Ally Financial, which became Chrysler Group's preferred lender as part of Chrysler's U.S.-steered bankruptcy in 2009, also ranked No. 1 in new-vehicle loans during the quarter.
Hyundai Capital America was a notable up-and-comer. Although it didn't make the top 20 lenders in 2009, it ranked No. 11 in the second quarter of 2010. The captive had tripled its share of the lease business it did in 2009.
