April 9 (Bloomberg) -- Toyota Motor Corp., Japan's largest automaker, and General Motors Corp. are recalling 662,093 small cars in the U.S. to fix a flaw that could cause power windows to fail.

The recall covers 539,500 of Toyota's 2003 and 2004 model Corolla and Matrix cars, the Toyota City, Japan-based company said in a statement today. GM is recalling 122,593 Pontiac Vibes, a version of Matrix built at a California assembly plant jointly owned by the two automakers, GM spokeswoman Carolyn Markey said.

In some cases, bolts in the driver and front-passenger doors may fail and allow the window glass to come loose, Toyota said. Toyota will begin notifying owners by mail starting late this month.

The move follows an announcement earlier today in Tokyo that Toyota is recalling about 630,000 minivans in Japan. Toyota President Katsuaki Watanabe has said the company is increasing efforts to ensure product quality after a jump in global recalls led Japan's Ministry of Transport in July 2006 to order improved defect inspections.

Cars with manual windows aren't affected by the recall, which covers production in Ontario, California, and Japan, spokeswoman Denise Morrissey said. GM's Vibe is built in Fremont, California, at New United Motor Manufacturing Inc., 50 percent owned by each company.

Toyota's American depositary receipts fell $1.23 cents to $95.20 at 4:15 p.m. in New York Stock Exchange composite trading. They've declined 10 percent so far this year.
