Toyota and U.S. regulators are looking into a possible recall on Toyota’s best selling car the Corolla. The National Highway Traffic Safety Administration has received 163 complaints about the steering in its 2009-2010 Corollas. Toyota said Wednesday it is looking into complaints about steering issues with the Corolla in the U.S., though it said it had received fewer than 100 reports and it was too early to consider a recall.

Toyota has been a top seller for decades and has sold nearly 1.3 million Corolla cars worldwide just last year. The recent rash of recalls has hurt Toyotas reputation resulting in sales to be the lowest since January 2006. Fears of an extended sales slump pushed Toyota’s shares down 3.7 percent in a flat market in Tokyo, compounding a slide that has sent the stock down 17 percent since its recall was announced on January 21.
