“I was traveling 60 MPH on the highway and my display started reading check hybrid system and check vsc system simultaneously. I searched and saw there was a recall for this exact issue (intelligent power module inside the inverter module) for certain vehicles of my exact make/model/year but for some reason my vehicle is not on the recall list. …”
NHTSA complaint #10882529, filed 2016-07, 130,000 miles“2006 Lexus rx400h totally shutting down while I was driving on i4 today. No power steering, no power brakes, engine died and luckily I was able to coast to a safe place from 70mph! Right before it happened, the check engine light came on, the engine misfired, then all of the lights on the dashboard came on including the check vcs, check hybrid and check anti-lock. Had to have it towed to our mechanic because it wouldn't start and could not be driven onto the tow truck. Codes that it threw said it was a high voltage system regenerative malfunction and a bad engine coil. …”

The cost is about $10k I did contact Lexus and received a call that they won't pay for the repairs. …”
NHTSA complaint #10616220, filed 2014-07, 65,000 miles“Having enjoyed owning a Lexus rx300, I made a huge investment and purchased the 2006 rx400h. In april of 2014, the vehicle would not start due to a failure of the hybrid system. I attempted to jump start the vehicle as suggested by the Lexus dealer. Upon further investigation I discovered the carpet inside the cabin area was soaking wet! The car had been outside in the rain with the windows, sunroof and doors closed. Also, I take the car to an automatic car wash on a regular basis. While loading the car on to the jerr-dan tow truck, a large amount of water poured out of the rear trunk area. …”
NHTSA complaint #10586442, filed 2014-05, 90,000 miles“Lexus rx400h brake momentary loss of braking efficiency. In frequently, after long steady controlled braking down a hill, the brakes on my Lexus will release without input from me for a second in time. The loss of braking causes me to press on the peddle and the car's braking performance returns to normal. Have experienced as I have decelerated to a stop for a signal light/stop sign. Not related to any bump in the road surface or the like. Frequency is weekly/monthly, but random in timing can't identify brakes from the system failure list. Chose powertrain out of frustration.”
