general problems of the 2006 Lexus Rx400h

The contact owns a 2006 Lexus Rx400h. The contact stated that while driving at 50 mph, the "all-wheel drive and hybrid system failure" warning messages were displayed. The vehicle was taken to an independent mechanic and diagnosed with inverter assembly failure. The vehicle was not repaired and remained with the independent mechanic. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The contact related the failure to NHTSA campaign number: 11v342000 (electrical system) however, the VIN was not included in the recall. The failure mileage was approximately 150,000.

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.

Engine shuts down with no warning with no power to control or navigate the vehicle. This happens while the vehicle is in motion.

I was traveling 60 mph on the highway and my display started reading "check hybrid system" and "check vsc system" simultaneously. I searched and saw there was a recall for this exact issue (intelligent power module inside the inverter module) for certain vehicles of my exact make/model/year but for some reason my vehicle is not on the recall list. I took it to the dealership and they said the regular 12 volt car battery was the issue so they replaced it and the light went off and the car tested normal for several days however when traveling on the highway about a week later the same lights came on again.

The contact owns a 2006 Lexus Rx400h. While driving approximately 45 mph, all of the lights on the instrument panel illuminated and the vehicle stalled. As a result, the brakes, power steering, and the windows became inoperable. The vehicle was towed to a dealer for diagnostic testing. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 140,000.

All service lights are on, abs vsc, and info display states some sort of vsc malfunction.

While backing out of my driveway, I bumped a tree with the passenger's side mirror. The impact was slight, estimated speed was 5mph as the driveway was icy. The wheels were not turned much as that portion of the driveway is straight. After the impact, I found that the wheel was very difficult to turn and the "p/s fail" light was lit on the instrument cluster. After examining the outside of the car, the only visible damage to the car was a paint chip on the mirror. There were no fluid leaks. There was a safety recall in Nov. 2011 (Lexus safety campaign 9lc) for this year make and model of vehicle due to others having similar sudden and unexplained loss of power steering. My insurance company denied my claim for repair because the experts they consulted said this type of impact could not have caused a loss of power steering. I have written Lexus describing the issue and am awaiting a response. Had the power steering failure occurred after hitting one of the numerous potholes on the highways, instead of in my driveway, the consequences to my wife and I could have been much more severe.

Leakage of coolant from the radiator discovered and in less than 50 miles an engine warning light lit, indicating failure of the hybrid synergy drive system , namely the hybrid inverter. Vehicle was brought into a Lexus dealership and the radiator and inverter were replaced.

The check engine light and p0aa6 warning illuminated and vehicle went completely dead, could not start up. There were cracked body seams above the rear door strut mounts allowing water intrusion to flood the entire bottom well under the floor boards which shorted out the entire hybrid battery system. There were no visible signs of water intrusion inside the cabin of the vehicle, nothing was wet. Apparently, Lexus has two TSB's on this issue, l-sb-0019-09 & l-sb-0045-09, on how to repair the seams since over time there appears to be a structural flaw allowing the seams to separate. The water intrusion happens silently and without warning and presents a severe safety hazard as you get water into an electrical system and parts begin shorting out without advanced warning. Imagine traveling at a high speed and the hybrid battery shorts and the vehicle abruptly stops! or an electrical short starts a fire! Lexus is aware of the potential problem and how costly the damage is and the safety risks associated as a result and has chosen not to issue a recall or limited campaign to allow for a simple repair of the seams to prevent major damage from occurring.

Abs system intermittent failure and master brake cylinder failure.

Tl- the contact owns a 2006 Lexus Rx400h. The contact was driving approximately 50 mph when the vehicle stalled without warning. All the electrical system failed. The contact was unable to restart the vehicle and it was towed to the dealer. The dealer diagnosed the failure as being the hybrid inverter battery which caused the vehicle to stall and shuts off all the electrical system. The vehicle was repaired. The manufacturer was not notified. The failure mileage was approximately 75,000 and the current mileage was 84,000.

1. None, lucklily I was accelerating from adead stop when the part seemed to pop out of gear. The car seemed to be running not quite as smooth 2 weeks prior so I had it checked @ the Lexus dealership. They found nothing wrong. If this part were to malfunction @ high speed I may not be able to issue this complaint. 2. Once, I will request old part if desired but expect Lexus to try to keep the part. Will NHTSA have it picked up from the dealership? 3. Car is in repair shop now. Nothing done yet. Hybrid inverter w/ converter quoted to be replaced with a different part #g92a0-48090, indicating to me that the manufacturer knows that the original part is defective.

The contact owns a 2006 Lexus rx400 hybrid (na). While driving approximately 70 mph, the power system shut down suddenly with no power brakes or power steering. The vehicle was towed to an authorized dealer who stated that a new hybrid system needed to be installed. The vehicle was repaired. The failure mileage was approximately 70,000.

While driving a 2006 Lexus 400h the engine, power steering, lights, everything! just quit and the car had to be maneuvered off the road with no power what so ever. It was very dangerous. The car's inverter had failed. This car has been maintained and serviced by the dealer for its entire life and has had no indication of a problem prior to the failure. The new inverter costs $8300! we will probably sell the car for salvage as its way too much money and who knows what will go out next! apparently this failure has occurred in other hybrids by Lexus and Toyota. Its a miracle that there was not an accident when the engine failed.

I read on the edmunds site for Lexus 400h, many owners are complaining about the failure of the electric inverter on the model year 2006. I own this car and I have not experienced any problem. I believe your agency should be looking into this situation as it appears that owners are reporting that Lexus is not admitting to this situation. One owner reports that Lexus knew about the problem in 2006 and changed to a different inverter starting with VIN #'s greater than 60036526. My car's vi # falls below that cutoff and I am very worried. When the inverter fails, all power to the vehicle fails and the driver is in serious trouble. Thank you for your concern for my safety while driving. Updated 06/02/11.

The contact owns a 2006 Lexus Rx400h. While driving 70 miles per hour the warning lights on the dashboard began to flash. The contact stated that the vehicle also lost power while driving. The contact was advised that the inverter was defective and that she would have to pay $700 to have the part installed. The failure and current miles were 140,000.

While driving on highway, car shut down totally.
