The oil cooler pipe broke on my 2011 lexus rx450h starving the engine of oil as I was driving home from work. The part is currently under warranty enhancement by lexus and is a known problem on my model year of vehicle. The malfunction is particularly insidious as oil only leaks when the engine is running, however with a hybrid when the vehicle stops the engine stops and so does the leak at least until you have reached a high enough speed for the engine to kick back on again. In my situation I received no check engine lights, oil lights or any other indication other then suddenly it felt like my engine was running a little rough. I immediately pulled over (I was just on a city street) and found the back of the vehicle was covered in oil. I had the vehicle towed to the local lexus dealership who identified the issue as the oil cooler pipe and lexus corporate paid for the repair under their warranty enhancement. When I picked the vehicle up from lexus of albuquerque I didn't even make it two miles away from the dealership before I started getting all kinds of lights flashing on my dash and the only power I had to move the vehicle was the electric hybrid drive. The vehicle was towed back to lexus which informed me a few days later that the engine had seized. I opened a new case with lexus corporate concerning the engine issues since my engine failure was a result of the warrantied part failing. Lexus's ultimate answer was sorry, but we are unwilling to help you as well as the answer from the dealership. Im the original owner of the vehicle and it has only ever been serviced at lexus dealerships, and not once did a service advisor/manager inform me that this part was a potential problem. For such an integral part that was poorly manufactured and can cause such expensive and catastrophic damage the oil cooler pipe needs to be recalled.

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.

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. It was a very dangerous situation with it shutting down on the interstate and I had no control what so ever! This was the second time this happened to me in this car and the computer was replaced the week after I purchased this car used in october 2017.

Braking system of the car failed. I could not stop the car and all the warning lights, engine warning lights, check hybrid system, and vehicle warning lights appeared on the dashboard of the car. The car was purchased new with 71 miles, the car was never in an accident, the car had nothing installed to it, the car was serviced by lexus for 10,000 mile oil change, and the car had 14693 miles when the braking system failed on august 7, 2017. The car was driven on a sunny day on dry flat asphalt road in chicago illinois. The braking system failure occurred at foster avenue and california avenue. Once all the warning lights appeared on the dashboard as listed above, the brakes in the car started to pump up and down every second by itself. The car was unable to stop as I forcefully stepped on the brakes. The brakes continue to pump up and down so I had to veer the car to the right side of the street while pressing on the parking brakes of the car to stop the car. The brakes continue to pump up and down for 10 minutes until I was able to forcefully step on the brakes again to shift the car into park to turn off the car. Once the car was turned on after 20 minutes the check hybrid system and a yellow triangle with an exclamation mark lights appeared on the dashboard of the car. I would have been in a serious or fatal accident if the braking system had failed since I was 2miles from entering the highway to go to work. The car was driven to lexus dealership where it was identified that a major internal braking system failure occurred between the skid control ecu and car's engine. If the car did not have manual parking brakes to slowly apply and stop the car, I would have been in a serious or fatal accident on foster avenue in chicago, illinois. If the braking failure happened on the highway at speeds of 55miles, I would have been killed or in a multicar fatal accident.

In october my wife was returning from a 9.5 hours trip with 1 fuel stop approx 4 hours from home. Exiting i95 the car had numerous warning lights with a complete loss of power (vsc, check hybrid system, awd system and others). She coasted the car to a parking lot, attempted to turn it off and back on, but there was still no engine or drive power. All dash lights working. We had the car towedto our home and I tested the battery and charging voltage, then had the battery load tested and found to be bad. Purchased an optima yellow top battery and all other dash warnings ceased. In november, again returning from a trip exiting i95 the car stalled and displayed only the check hybrid and awd lights. This time turned the car off for 30 seconds and then back on. The engine turned on and hybrid motor function resumed with the "check hybrid light" still illuminated. I disconnected the battery for a minute and all warning lights went off with normal engine and hybrid drive function. I was told to contact lexus if it occurred again. One month later again returning from a trip, exited i95 and once the car was slowed to about 35 MPH car lost power, warning lights "awd" and "check hybrid" illuminated and car had entered a "limp" type of mode with some power with the gas pedal and limited speed. Power distribution screen showed no power movement from the engine/battery/wheel charging. The check engine light was also illuminated. Pulled to a parking lot turned off momentarily and then back on, resuming normal function. "awd" warning went away, but "check hybrid" and check engine lights were both on. One day prior to the appt at lexus the car was used with the warning lights still illuminated, still functioning normally. The lights, at some point during the drive went out on their own. The service appointment was again cancelled on the wednesday before the schedule.

Vehicle appeared to enter "fail-safe" mode with reduced power while driving on highway resulting in reduced ability to control vehicle. Several minutes later, while driving on city street, the vehicle eventually lost all power while stopped at red light and could not be driven, and power-steering also failed. Warning lights included "check hybrid system," "check engine warning light," "slip indicator," and perhaps others. After turning off and turning back on at red light, there sufficient power to drive vehicle again, though "check hybrid system" and "check engine warning light" remained illuminated. A couple hours later, after restarting vehicle, warning lights were no longer on and vehicle could be driven normally. The condition appears similar to issue in toyota safety recall 13v‑396. However, our vehicle's VIN is not in the range of that recall. We have not yet contacted lexus dealership regarding this issue.

While driving with the vehicle on cruise control, the vehicle went from 75 MPH to 0 on the interstate. I was able to coast into a nearby rest area. At this point the car would start, but none of the systems would operate. The dash displayed several system failures to include the hybrid system, check engine, pre-collision system, braking system and all-wheel drive system. This is a brand new vehicle purchased from a lexus dealership. The milage at the time of breakdown was only 883 miles. The dealership labeled this event as a catastrophic failure, but I have received no valid explanation as to what happened to the vehicle.
