Toyota Motor Engineering & Manufacturing has issued a recall for the Lexus RX400h.
Description of Recall
Toyota is recalling certain model year 2006-2010 Highlander Hybrid cars manufactured February 16, 2005, through July 29, 2010; and model year 2006-2008 Lexus RX400h cars manufactured February 23, 2005, through December 2, 2008. The intelligent power module (ipm) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be ilLuminated on the instrument panel.
Severity of the Defect
The car may enter a fail-safe/limp-home mode that limits the drivability of the car. It is possible that the hybrid system will shut down while the car is being driven, causing the car to stall unexpectedly, increasing the risk of a crash.
Lexus’s Recommended Action
Toyota will notify owners, and dealers will replace the ipm free of charge. Owners may contact Toyota at 1-800-331-4331. Vehicles that had their ipm replaced under recall 11v-342 are not affected by this campaign.
