Hello, I had this issue on my Lexus RX400H recently, and it was diagnosed and repaired by a third party auto repair shop at my expense. I want to know if I have any recourse to recover my cost Approx $700. Thanks! VIN Recall Consequence: THE VEHICLE MAY ENTER A FAIL-SAFE/LIMP-HOME MODE THAT LIMITS THE DRIVABILITY OF THE VEHICLE.

I am financing a 2006 Lexus rx400h hybrid and the other day I went out to start it up and the light and everything came on but would not display ready and would not start. Check hybrid system with red triangle was on dash display along with several other warning lights, also when I put the key in the ignition it will release in the ACC position. Where I am purchasing the vehicle will not fix it saying my Vin is not part of the recall list and the lexus dealership to me it was to late to have the recalled parts replaced for free. What do I do?

This vehicle seems to have a well-documented problem with water intrusion that damages the ECU and hybrid battery. The 2006 and 2007 RX400h has the HV battery located under the seat, which is the low spot in the rear section of the car. If water is spilled or the body has a water leak, the water will pool at the center of the battery. Lexus considered this, and added a drain under the battery, but the drain has a filter, presumably to keep insects out, and the filter is easily clogged. This, coupled with a pattern problem of split body seams near the rear hatch strut mount causing a water leak in the rear of the car, has created isolation faults in many of the RX400h SUVs. The condition presents as warnings on the instrument cluster and a no-start condition where the vehicle is inoperable. A search for "lexus ECU water intrusion" brings up my vehicle's exact model and year so this is well-documented.

My car exploded- huge fire. I was not driving- it had been parked. The fire marshal indicated that it was an electrical problem located near the battery. There we no indicators of any issues. I only had liability on the car- so i am out of luck. but the NYFD inspected. It happened on Wednesday 9/29/21. Was inspected on 9/30.

NHTSA investigations

RQ10003 · Unintended And Uncontrolled Acceleration

Opened Feb 16, 2010 · Closed Mar 1, 2011

Status: closed (inferred from source dates) · Electrical System:software; Vehicle Speed Control:accelerator Pedal

On February 16, 2010, NHTSA'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.NHTSA 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, NHTSA 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 NHTSA 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 NHTSA opened RQ10-003, NHTSA launched a ten-month study of potential electronic causes of unintended acceleration in Toyota vehicles.NHTSA launched the study in the spring of 2010 in light of concerns aired in Congressional hearings.NHTSA 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 NHTSA's website.NASA's report is entitled Technical Support to the National Highway Traffic Safety Administration (NHTSA) on the Reported Toyota Motor Corporation (TMC) Unintended Acceleration (UA) Investigation, NESC Assessment No. TI-10-00618 (Jan. 18, 2011).NHTSA'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. NHTSA 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.
