Tl* the contact owns a 2006 lexus rx400h. The contact was driving approximately 70 MPH when the vehicle suddenly stalled without warning. The contact was unable to restart the vehicle and it was towed to the dealer. The dealer advised the contact that the hybrid inverter had failed and would need to be replaced. The vehicle was not repaired. The failure mileage was approximately 123,300.
No failure, yet. But vehicle (lexus rx400h - 2006) is a hybrid. There is a separate cooling system for the hybrid components (inverter, and electric motors in transaxle). Coolant is leaking from the transaxle. If all coolant leaks out, the inverter will fail. Without the inverter, there is no power - no electric steering, no electric brakes, and no motive power to the wheels. Additionally, the coolant may leak somewhere or onto something that may short out or cause a fire. This is not a leak from a worn out coolant hose, but directly from the transaxle. Being a hybrid, the availability of electric power is absolutely essential. There have been reports of inverters failing (just check the lexus. Toyota and other hybrid forums) on the highway at speed, leading to a complete loss of power. To the best of my knowledge, there have been no injuries or accidents, but the potential is frightening.

Vehicle lost control on brakes and almost stalls while driving. It happened 1 year ago and no problem was found and now it happened 3 times. The dealer is unable to find what is causing it. It has been a hazard to drive. The computer was changed and still it occurred and is with service department.
