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.
Brakes
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?
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.
