Japanese car manufacturers are finding a problem in the Hybrid System Inverter on each car. Intelligent Power Module (IPM), which lies in it contains a control board with transistors.
"Some parts of transistors on the control board, in the subject vehicles are not subject memdapat enough solder. This is potentially damaged from the heat caused by a large current flow during high-load driving, "explained Toyota as reported autoevolution.
If this happens, the warning light will light in the range on the instrument panel. In most cases, the vehicle will enter a mode of fail-safe driving, resulting in reduced power but the vehicle can still be driven for short distances. In limited cases, the power supply circuit fuse may blow up when the transistor is damaged. If the fuse is broken, the hybrid system will stop and the vehicle will immediately cease.
However, Toyota had a little problem with the spare parts needed to fix the problem ini.Surat first notification will be issued in mid-July 2011, after the repair parts available and provided at no charge.
