Electrical system
- What is wrong
- Toyota is recalling certain model year 2006-2007 highlander hybrid and lexus rx400h passenger cars manufactured from february 16, 2005, through august 30, 2006. A module inside the inverter module may contain inadequately soldered transistors that during high-load driving, may be damaged by heat caused by the large current. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.
- Risk
- The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.
- Remedy
- Toyota/lexus mailed an interim owner notification on july 19, 2011 to advise owners of this recall and the fact that they will receive a future notice when parts become available to complete repairs. Toyota dealers will inspect the hybrid inverter production number to determine whether the inverter contains suspect transistors and replace the module free of charge. Owners may contact toyota at 1‑800‑331‑4331.

Pedestrian alert sounds
the federal safety agency received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, the federal safety agency opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified the federal safety agency he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by the federal safety agency regarding the subject matter of the petition.

Unintended and Uncontrolled Acceleration
On February 16, 2010, the federal safety agency's Office of Defects Investigation (ODI) opened RQ10-003 to determine whether the scope of prior Toyota recalls relating to potential unintended acceleration were sufficiently broad, including, among others, Toyota recalls 07E-082, 09V‑388, 10V‑017, and 10V‑023.the federal safety agency also requested information regarding potential electronic causes of unintended acceleration in Toyota and Lexus vehicles.I. Pedal Interference from Floor mats, Carpet Covers and Plastic Pads in Carpets.During the RQ10-003 investigation, ODI reviewed a large volume of documents to assess whether additional vehicles should be recalled.Following the agency's analysis, the federal safety agency requested that Toyota recall additional vehicles.Toyota complied with the agency's request.The details of these recalls are set forth more fully in Toyota's reports to the federal safety agency pursuant to 49 CFR Part 573.These recalls are as follows:Recall 11V‑112: (1) model year (MY) 2004-2006 Toyota Highlander and Highlander Hybrid; and, (2) MY 2004-2007 Lexus RX330,RX350, and RX400h (hybrid model). The total estimated population under this recall is 769,379 vehicles.This recall remedies potential accelerator pedal entrapment caused by a loose floor carpet cover (trim panel). Recall 11V‑113: (1) MY 2003-2009 through 2009 Toyota 4Runner; (2) MY 2006-2010 Toyota RAV4; and, (3) MY 2008-2011 Lexus LX570.The total estimated population under this recall is 1,381,000 vehicles.This recall supplements recall 09V‑388 and remedies potential accelerator pedal entrapment by an unsecured floor mat.Recall 11V‑115: (1) MY 2006-2007 Lexus GS300 (all wheel drive vehicles); and, (2) MY 2006-2007 Lexus GS350 (all wheel drive vehicles). The total estimated population under this recall is 19,647 vehicles.This recall remedies potential accelerator pedal entrapment caused by inadequate clearance between the pedal linkage and a plastic pad embedded in the vehicle's carpet.II. Potential Electronic Causes of Unintended Acceleration.After the federal safety agency opened RQ10-003, the federal safety agency launched a ten-month study of potential electronic causes of unintended acceleration in Toyota vehicles.the federal safety agency launched the study in the spring of 2010 in light of concerns aired in Congressional hearings.the federal safety agency enlisted engineers at the National Aeronautics and Space Administration (NASA) with expertise in areas such as computer controlled electronic systems, electromagnetic interference and software integrity to assess whether electronic systems or electromagnetic interference played a role in incidents of unintended acceleration in Toyota vehicles.That study has concluded.Two reports are associated with the study and are available on the federal safety agency's website.NASA's report is entitled Technical Support to the federal safety agency on the Reported Toyota Motor Corporation (TMC) Unintended Acceleration (UA) Investigation, NESC Assessment No. TI-10-00618 (Jan. 18, 2011).the federal safety agency's report is entitled Technical Assessment of Toyota Electronic Throttle Control (ETC) Systems (Feb. 2011).Both reports should be read in conjunction with each other. As stated in its report, NASA did not find an electronic cause of large throttle openings that can result in unintended acceleration incidents. the federal safety agency did not find a vehicle-based cause of unintended acceleration incidents other than the physical pedal interference causes that are being addressed by Toyota's recalls. This RQ is closed.

What 2006 Lexus RX Hybrid owners say
Most recent owner complaints, unedited.
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.
Check hybrid system lights came on and the vehicle failed to start. This is the second occurrence. The inverter was replaced following the first occurrence in 2011. The vehicle was moving during the first occurrence.
The hybrid battery failed, power inverter, locking up power steering and my car was not able to operate on the road. I was quoted 7500$ cost. I have read of similar problems occurring. I would like help repairing from lexus
Engine shuts down with no warning with no power to control or navigate the vehicle. This happens while the vehicle is in motion.
Years ago, I began to have a series of battery failures while still under warranty. Each time, lexus just told me it was a dead battery, and replaced it (pro rata, not free to me). I gradually became aware that these failures were being accompanied by a message to "shift to p when turning off ignition," which I always do. I suspected that the vehicle was somehow sensing that the vehicle was not level and was wrongly engaging some sort of stability system, draining the battery. The current episode is accompanied by a "vsc" error message, which is indeed a stability system. Others have reported this online as having killed their vehicles while they are in motion. I am fortunate that this did not happen to me...yet. However, I am now out of warranty and am told this will cost over $8000 to fix. I therefore want to add my voice to the growing number of affected customers--lexus should be responsible for this clear flaw in their manufacturing!
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.
Tl* 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.
As we were approaching a stoplight, a warning sound went off, followed by the entire car shutting down and refusing to turn on again. The "hybrid battery failure" warning message came on, and we were unable to turn the car on again. We were able to move the car to a parking lot, where we waited for a tow truck. The dealership told us we must have left the windows open - not the case, since it was still towards the end of a cold winter. The windows and everything else had been closed for several months. However, through some research, it appears that this issue occurs in these vehicles after a cold and wet period; certain seams will come apart, the internal components will flood with water over time, and the hybrid system will short out to the tune of 5+ thousand dollars. Since this is a known issue, and not due to neglect or lack of maintenance by the consumer, it seems that this is the fault of the manufacturer.
