Vehicle could suddenly stop
- Defect
- It is possible that due to variations in the build specification of the Intelligent Power Module (IPM) which includes the Insluted-Gate Bipolar Transistors (IGBT's) the lead-based solder could be affected by abnormally higher operating temperatures. This could result in a degrading of the solder and eventually heat damage to the IGBT's. If this occurs then warning lights on the instrument panel will illuminate. However if the driver fails to heed these warnings or the main power supply fuse blows then the vehicle could stop without warning.
- Remedy
- Recall all the affected vehicles and replace the IPM unit with a upgraded unit.
