   Brake system sets a high tone pitch indicating failure accompanied by all Brake, ABS, PS, Traction Control Lights. This is an know failure for Hybrid systems. It can occur completely random, while driving without notice. Complete brake pressure is lost with exception of a hard feel to the pedal that allows some incomplete breaking to occur and can also cause locking of the brakes at slower speeds. We replaced The brake actuator as recommended with factory new in March of 2024 Started much earlier. Problem has returned Summer of 2025.

   After adding gasoline to the tank, gasoline begins dripping from the left rear of the vehicle to the rear of the left rear wheel well. This happens even if the tank is only filled to 2/3 of a tank. I have stopped filling up since when the tank is filled up a LARGE amount of gasoline leaks out onto the ground. FIRE HAZARD while parked or driving. I have seen HUNDREDS of reports of this problem reported online.

   From what I have been reading on that year and model, there seems to be major issues with the invertors. Like many I was driving on the highway and the vehicle just quits. This put me and many others in a very dangerous situation and I could have been hit at high rates of speed. If as many people are having these issues, then Lexus needs to step up and recall this part before someone gets killed

   The power steering and hybrid system failed and vehicle completely stopped in middle of busy freeway with no prior warnings or issues before. The safety of my son and I, and others around me during the abrupt stop of the engine. I could not move out of way. The vehicle has been serviced for this exact issue during a recall campaign lasting from 2011 to 2014. Ten years later and it is still happening! There were NO warning lamps or messages or symptoms prior to this failure. It just passed vehicle inspections for the year

   Dear manager: I have this 2006 LEXUS RX400H which has CHECK VSC SYSTEM and CHECK HYBRID SYSTEM problems. When I was driving on the highway, the cruise control button is unable to turn on, when at speed of 65 MPH it will suddenly stall in the middle of the road and the READY light will be off and the vehicle has to be stopped by the emergency lane which is REALLY DANGEROUS. I have searched online and found out there were many complains about this issue and LEXUS issued a recall for this type of car and the dealer can change the inverter and ICM free of charge. This recall link is as follows: https://static.nhtsa.gov/odi/rcl/2011/RCONL-11V342-6633.pdf So tonight I am sending this message to see if you can help me to solve this problem.

    I am financing a 2006 Lexus rx400h hybrid and the other day I went out to start it up and the light and everything came on but would not display ready and would not start. Check hybrid system with red triangle was on dash display along with several other warning lights, also when I put the key in the ignition it will release in the ACC position. Where I am purchasing the vehicle will not fix it saying my Vin is not part of the recall list and the lexus dealership to me it was to late to have the recalled parts replaced for free. What do I do?

13. Filed Jan 28, 2023Failure Jan 6, 2023seattle, WAElectrical system, Power train

    This vehicle seems to have a well-documented problem with water intrusion that damages the ECU and hybrid battery. The 2006 and 2007 RX400h has the HV battery located under the seat, which is the low spot in the rear section of the car. If water is spilled or the body has a water leak, the water will pool at the center of the battery. Lexus considered this, and added a drain under the battery, but the drain has a filter, presumably to keep insects out, and the filter is easily clogged. This, coupled with a pattern problem of split body seams near the rear hatch strut mount causing a water leak in the rear of the car, has created isolation faults in many of the RX400h SUVs. The condition presents as warnings on the instrument cluster and a no-start condition where the vehicle is inoperable. A search for "lexus ECU water intrusion" brings up my vehicle's exact model and year so this is well-documented.
