Had an issue while driving the 2018 rx450h on may 4th where the car lights came on....engine light, awd, ABS, etc and the car stalled completely. Had towed to dealership and they stated that it was 'fixed'. 4 weeks later while traveling at 70+ MPH on major interstate, car stalled again the same way....lights on, etc.. Was luckily in the right lane of 4 wide traffic as car went to a stop quickly. Was stranded in a heavy traffic lane, car would not shift into neutral to push out of traffic. Was 2 hours from home, had another lexus dealership tow the car and they came back within a few hours and said it was the fuel pump. I was not aware of the recall till then and this 18' 450h was not on the current list which only proves that this issue is systemic. Fortunately, no one was hurt in these 2 occurrences but we are not driving this car again under no circumstances.

Tl* the contact owns a 2006 lexus rx400 hybrid. When attempting to accelerate from a stop, driving on an incline, or making turns, the vehicle stalled intermittently. In addition, the check engine, hybrid check, and battery warning indicators illuminated. The contact coasted the vehicle to the side of the road and powered off the engine. Once restarted, the vehicle drove normally; however, the failures recurred. The vehicle was taken to treasure coast lexus (located at 5121 us-1, fort pierce, fl 34982, (772) 460-0000) where the technician cleaned the mass air flow sensor, cleared the failure codes, and test drove the vehicle in check mode. The dealer stated that the vehicle was operating as expected. The dealer swapped the circuit open relay with the ignition relay to eliminate the relay as the failure. The check engine warning indicator remained illuminated. The dealer informed the contact that the vehicle was previously repaired per the federal safety agency campaign number: 13v396000 (hybrid propulsion system). The vehicle was taken to the dealer approximately four times for the same failures, but there was no resolution. The manufacturer was notified of the failures and provided a case number.

My vehicle is displaying a hybrid system check message, and the hybrid system malfunctions. This is causing the vehicle to stall in drive while the vehicle is in motion. The vehicle loses all capabilities to properly function. I was on a city street when this happened, and had to coast the vehicle downhill in traffic to pull over. My engine check light also illuminated. This vehicle has not been driven regularly, as I just purchased it from a dealership that had been sitting on it for some time. The carfax check out for the vehicle, so it could be a faulty electrical system inverter.

While driving from florida to fairfax, ca the vehicle stalled ~10 time unexpectedly with loss of power brakes and power steering, making a very dangerous situation. The "check hybrid system and check vsc system" showed on the dash. Clearing the codes restarted the vehicle. I stopped in denver, co at kuni lexus of greenwood village, whom road tested the vehicle for 30 miles but were unable to duplicate the fault. Obdii dtc p3105 was read on my scanner before arrival. I have researched the failure more and found out on lexus tis system; on 01/15/2014, lexus of miami claimed to have completed safety recall 13v396000 (intelligent power module (ipm) solder failures) but they only diagnosed some other problems and did not have time to perform this recall, neither did the inform me of it! I stopped at lexus of tacoma at fife, wa and they denied diagnosis due to minor body damage on the rear quarter panel where they claim water came in. This is not the location of water intrusion! The location is due to body seam cracks above that plain of the quarter panel damage, near the rear gate struts and hinges (see l-sb-0019-09), but they wouldn't look at that either and told me to go to their sublet body shop where the manager agreed with me that the water leaks into the high voltage battery pack/controller area was from the l-sb-0019-09 and not the quarter panel area. I sealed up all possible water intrusion areas and disassembled the hv battery pack area to see how much and where the water was (many photos) and dry it out with several days of sunshine here in fairfax, ca. I informed lexus corp about the relative recall/sb and they denied to complete it! The vehicle is back together and I am waiting on your response. I can be reached by email (I don't carry a cell phone) thank you!

While driving 50 MPH on a busy road in ma the car abruptly stalled and lost power and ability to control it other than with a glide and manual steering to pull off the roadway and out of busy traffic, which could have been deadly for both our son and the people driving around him. Upon having it towed to the lexus dealership, they informed us that the dashboard sensors were indicating a faulty oil pump and possibly a failed inverter. "they had no way of determining if the inverter was faulty without first repairing the oil pump for $1200." upon repairing the oil pump, we learned the inverter ($8000 repair) was damaged and needed repair. The dealer could not explain this and had "never seen or heard of such a thing." further investigation on our part, showed that over 235,000 2006 and beyond toyota hybrid vehicles had been recalled for a faulty inverter in 2013. While our vehicle VIN does not show up on the recall list, we believe we are experiencing the exact same problem. Lexus corporate is denying any part in this and refused to stand behind the vehicle with only 109,000 miles and quickly closed the case. Our concern is there are more vehicles out there with this issue, and that it could be deadly for operators and drivers. If the inverter was identified as faulty already on over 235,000 vehicles, an expanded search on additional vins needs to take place. Lexus was very comfortable in confirming that they did not and would not stand behind their vehicles beyond 100,000 miles, and essentially, it was good that our son did not get injured, and sorry our car was essentially totalled (value of vehicle is approx $9000 based on kelly blue book) for the faulty inverter which was not identified on the recall.
