Toyota has issued another recall. This time, the automaker is recalling more than 400,000 hybrid vehcles, including the 2010 Prius and the Lexus HS250h, because of problems with their brakes.

At a news conference to announce the hybrid recall, Toyota President Akio Toyoda said a fix for the brake problem would take about 40 minutes and be handled by dealers. Toyoda also apologized to consumers for the concern and inconvenience the Prius and other recent recalls have caused, and promised to “redouble our commitment to quality.”

The new recall involves 133,000 Prius cars and 14,500 Lexus HS250h vehicles sold in the U.S.; nearly 53,000 Priuses in Europe; and 223,000 hybrids sold in Japan. The recall followed complaints from some Prius owners that brakes on the cars would temporarily stop working on bumpy or slick roads.

Last week, Toyota acknowledged that the braking system on third-generation Priuses had a design flaw, and that it had already corrected the brake problem for Prius models sold since late January. At the time Toyota said it was working on a fix for Prius hybrids already on the road.

At the same time, the U.S. National Highway Traffic Safety Administration (NHTSA) announced it had opened a formal investigation of the Toyota Prius, model year 2010, relating to reports of momentary loss of braking capability while traveling over an uneven road surface, pothole or bump. The NHTSA said it had received 124 reports from consumers, including four reports alleging that crashes occurred.

The mechanical parts that make up the brake system in the Lexus HS250h are identical to those in Toyota’s 2010 Prius, but the two gas-electric hybrid cars use different software systems to control the way the brakes are used.
