Lexus RX400h Recall 11V342000

Warning Lights, Drivability Issues, and/or Stalling Due to Failed Hybrid Inverter Module

Drive Train, June 29, 2011

RepairPal Expert Overview

Our Quick Take:

Due to a failure inside the hybrid drive inverter module, various dash warning lights may illuminate, drivability may be impaired, or the vehicle may stall unexpectedly, increasing the risk of a crash.

What Should You Do?

This should be considered a high priority recall. Dash warning lights could display, drivability concerns could develop, or the engine could stall without warning. Please contact your Toyota or Lexus dealer. They will check to see if your specific vehicle is affected and advise you on what to do next. Always have your vehicle identification number (VIN) handy when you call.

Summary:

A module inside the hybrid drive inverter module may contain inadequately soldered transistors. These solder joints could fail under high electrical loads, resulting in illumination of various dashboard warning lights, drivability concerns, and/or engine stalling. If the vehicle were to stop unexpectedly, this would increase the risk of a crash. Owners will be notified in July 2011 if their vehicle is involved in this recall. They will received a second notice when parts become available. Dealers will inspect the hybrid inverter module production number to determine if the inverter contains the suspect transistors. They will replace any affected modules.
