Toyota Recalls 270K Priuses Some 2010 models have a potential brake defect By John Johnson, Newser Staff Posted Feb 4, 2010 1:22 PM CST 12 comments Comments Workers give the final checkup on new Prius hybrid vehicles at Toyota Tsutsumi Plant in Toyota, central Japan. (AP Photo/Shizuo Kambayashi, File) (Newser) – Toyota's troubles deepened today as it plans to recall 270,000 Priuses in the US and Japan over a potential brake defect, says a report in the Nikkei news service. The development comes just hours after the Transportation Department announced its own investigation into the glitch affecting 2010 models. The recall would cover the third-generation Priuses that came out in May. Drivers reported a pause in braking, especially on bumpy or slippery roads, reports MSNBC. A company spokesman says the glitch apparently arises during the changeover from traditional hydraulic brakes to the electronic system. The recall is separate from those on other Toyota models involving out-of-control acceleration.
