Washington, D.C. – A new recall involving the 2010 Toyota Prius and Lexus HS 250h hybrids for brake system problems has started in the U.S., according to the National Highway Traffic Safety Administration (NHTSA). The agency said that some 2010 Camry models prone to brake fluid leaks have also been recalled.

Toyota Motor Europe has also announced that it is recalling 52,902 Prius units in Europe to modify the software used to manage the vehicle’s anti-lock braking system.

“Last Thursday, NHTSA opened a formal investigation of 2010 Toyota Prius hybrid vehicles in response to consumer complaints about braking difficulties, and today, Toyota has acknowledged a safety defect,” said U.S. Transportation Secretary Ray LaHood. “When I spoke with Toyota president Akio Toyoda last week, he assured me that his company takes U.S. safety concerns very seriously. The U.S. DOT will remain in constant communication with Toyota to hold them to that promise. In the meantime, if you are concerned about your car’s braking performance, contact your Toyota dealer.”

NHTSA announced last week that it was opening a formal investigation into the 2010 Prius to look into allegations of momentary loss of braking capability while travelling over an uneven road surface, pothole or bump. The Office of Defects Investigation had received 124 reports from consumers, including four reports alleging that crashes had occurred.

Toyota Motor Europe said that there have been no reports of crashes of potentially affected vehicles in Europe.

The U.S. publication Automotive News, quoting NHTSA spokeswoman Karen Aldana, said that the agency is also considering a formal investigation into customer complaints of electric power steering problems in 2009 and 2010 Toyota Corolla models. The publication said that it found the Corolla had been the subject of 83 power steering complaints since April 2008, with 76 people reporting that the vehicle unexpectedly veered to the left or right at speeds of 64 km/h and up.
