Toyota Motor Corporation is in the news again, and for the second time in as many weeks, it is for all the wrong reasons. After last week’s massive recall of faulty accelerator pedals on eight different models, the U.S. Department of Transportation is now investigating the 2010 Toyota Prius for reports of defective brakes.

The National Highway and Safety Administration has reportedly received more than 120 complaints from consumers, including four reports of minor accidents, two of which resulted in injuries, according to Business Week.

On Thursday, officials from the Japanese automaker hinted that they may have to issue a recall on the world’s best selling hybrid car.

“We are considering some kind of measure to take,” said Toyota spokeswoman Ririko Takeuchi. “We would like to make an announcement as soon as an action has been decided upon.”

The news of the investigation came only a day after Toyota reported strong third quarter earnings that easily trumped Wall Street estimates, according to the Washington Post.

Most customer complaints involving the 2010 Prius are due to a split-second delay in switching between the traditional hydraulic brakes and the electronic braking system.
