Toyota to recall 1.9 million Prius cars for software defect in hybrid system

Wednesday, 12 Feb 2014 from CNBC

Toyota Motor on Wednesday issued a recall covering all 1.9 million of the third-generation Prius cars sold worldwide, due to a programming glitch in their hybrid system.

About half of the recalls are in Japan and 713,000 in North America, a Toyota spokeswoman said. No accidents have been reported related to the defect.

Toyota said the problem was in the software used to control the boost converter in a module that is part of the hybrid system.

“The setting of the software could cause higher thermal stress in certain transistors within the booster converter, and these transistors could deform or become damaged as a result,” Toyota said.
