Toyota has a new issue with their vehicles. This time problems has touched their word-popular hybrid Prius. The U.S. Transportation Department has started to investigate brake problems which start to occur in 2010 Toyota Prius models. For now more then a hundred of Prius owners reported about brake issues. Several of them stated that due to the brake system, they’ve appeared in an accident.

The U.S. investigation comes after the Japanese government ordered Toyota to probe brakes on the new Prius there. As a result, the company changed the anti-lock brake systems on those vehicles sold since last month. In a statement the company said Toyota will continue to evaluate the condition as it relates to owner complaints and will keep the National Highway Traffic Safety Administration informed of its progress. Critics attribute Toyota’s recent turmoil to a company growing too big too fast. Others like “Motor Trend’s” Todd Lassa think the auto company could also be a victim of rapidly changing technology.

Obviously, those issues won’t increase Toyota’s reputation, which is much hurt from their stuck pedal issue.
