RepairPal Expert Overview
Various warning lamps may illuminate, drivability concerns could be encountered, or the the hybrid drive system could shut down causing the vehicle to stall unexpectedly increasing the risk of a crash.
Toyota will notify owners of affected vehicles beginning late September 2013. If don't receive notification and you feel you should, please contact your dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call. Please note: Vehicles that had their Intelligent Power Module (IPM) replaced as part of recall 11V-342 are not affected by this recall.
Two of the main control modules for the hybrid drive system are the Inverter Module and the Intelligent Power Module (IPM), which is located inside the Invertor Module. The IPM can operate at temperatures high enough to damage its electrical solder connections. Damaged solder joints can result in illumination of warning lights, various drivability concerns, and possible stalling of the hybrid drive system. Dealers will replace the IPM on affected vehicles to correct this concern.
