I HAVE BEEN TRYING TO HAVE LEXUS WOODLAND HILLS FIX MY 2007 RX 400H REGARDING AN ISSUE WITH MY ALARM. MY ALARM GOES OFF RANDOMLY. I HAPPENED TO FIND OUT ABOUT IT WHEN A CLASS I WAS ATTENDING ANNOUNCED OVER THE LOUD SPEAKER THAT A GOLD LEXUS SUV HAD ITS ALARM GOING OFF. I WENT OUT, RESET IT, AND WENT BACK TO CLASS. WHEN THEY GOT ME OUT A SECOND TIME ABOUT A HALF AN HOUR LATER, I JUST LEFT THE CAR UNLOCKED SINCE I WAS IN A SAFE, SECURED LOT. SINCE I AM NOT USUALLY AROUND MY CAR AT THE STORE, MALL, ETC, I HAVE NO IDEA HOW MANY OTHER TIMES IT WENT OFF UNTIL I WAS AT A FUNERAL IN SIMI VALLEY. WHILE WE WERE LEAVING, SOMEONE NOTIFIED ME THAT THE ALARM WAS GOING ON & OFF FOR AN HOUR! I TOOK IT TO WOODLAND HILLS LEXUS WHERE THEY SUPPOSEDLY CORRECTED THE ISSUE. IN JUNE 2011, IT WENT OFF YET AGAINWHILE I WALKED WITH A FRIEND IN A GATED, SECURE COMMUNITY ON A CUL-DU-SAC WITH NO TRAFFIC. MY FRIEND TOLD ME LATER THAT HER NEIGHBOR CAME OVER TO COMPLAIN ABOUT THE CAR ALARM GOING OFF AGAIN AND AGAIN. TOOK IT TO WH LEXUS FOR SERVICE AGAIN. LAST TIME WAS WHEN I WAS AT A FRIENDS HOUSE AND PARKED IN HER DRIVEWAY. AFTER ABOUT 30 MINUTES OR SO, I HEAR THE ALARM GO OFF. I TURNED IT OFF BUT NOT BEFORE HER DISTRAUGHT NEIGHBOR CAME OVER AND SCREAMED AT ME ASKING ME TO MOVE MY CAR. WH LEXUS HAS HAD MY CAR SINCE JULY. CAN'T FIGURE OUT WHAT THE PROBLEM IS AND THEY ARE HAVING TROUBLE GETTING THE WARRANTY COVERAGE (SOLD BY LEXUS) TO KICK IN. IT IS A SAFETY ISSUE BECAUSE THEY WANT TO DISCONNECT MY ALARM - WHICH IS ABSOLUTELY NOT AN ACCEPTABLE ANSWER. *TR

PE11005 · Hybrid Inverter Failure - Vehicle Stall

Opened Feb 15, 2011 · Closed Jul 20, 2011

Status: closed (inferred from source dates) · Hybrid Propulsion System: Inverter

In a June 29, 2011 letter to NHTSA, Toyota submitted a Defect Information Report regarding a safety recall of certain Toyota Highlander Hybrid and Lexus RX400h vehicles to address a defect condition with the hybrid inverter assembly (NHTSA Recall No. 11V-342).Toyota's letter identified a defect related to inadequately soldered transistors on the Intelligent Power Module (IPM) of some of the subject vehicles that could result in sudden loss of power while driving.Toyota's remedy procedure instructs dealers to inspect the hybrid inverter production number to determine if the inverter contains suspect transistors.If so, the dealer will replace the IPM.The recall covers approximately 45,528 model year (MY) 2006 and 2007 Toyota Highlander Hybrid vehicles manufactured from February 16, 2005 through August 29, 2006 and approximately 36,745 MY 2006 and 2007 Lexus RX400h vehicles manufactured from February 23, 2005 through August 30, 2006.This Preliminary Evaluation is closed.

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.
