Toyota woes mount as government examines Prius brakes

WASHINGTON (AP) — Toyota faced mounting pressure today as the government opened a probe of brake problems with the Prius, a crown jewel of its lineup. The beleaguered automaker said it was "too soon" to decide whether to add the hybrid to the millions of cars it has recalled.

Some owners of the 2010 Prius have reported their brakes do not always engage immediately when they press the brake pedal, or that the brakes have an inconsistent feel. The National Highway Traffic Safety Administration said it would assess the scope of the problem and the safety risk to about 37,000 cars that could be affected.
