WHILE DRIVING HOME FROM WORK IN NORMAL FREE-FLOWING TRAFFIC CONDITIONS ON THE FREEWAY, SEVERAL LIGHTS CAME ON THE DASH INDICATING BRAKE ISSUES INCLUDING VSC, ABS, SKID, PARKING BRAKE LIGHT. CONTINUED TO CAUTIOUSLY DRIVE HOME, BRAKES SEEMED OK. HAD OUR NON-DEALER MECHANIC LOOK AT THE BRAKES ALL WERE FINE AND HAD RECENTLY BEEN REPLACED. HE COULD NOT FIND A BRAKE ISSUE. TOOK TO THE LOCAL TOYOTA DEALER AND ONE CODE CAME UP C1391 "ABNORMAL LEAK IN ACCUMULATOR" AND WAS TOLD I NEEDED A NEW BRAKE ACTUATOR AT THE COST OF $3273.00. DIAGNOSTIC COST $138.00. ADDITIONAL INFORMATION ON DIAGNOSTIC PAPERWORK FROM DEALER SAYS, "CHECK FOR DTC'S FOUND C1391, CHECK FOR FLUID LEAKS, COULD NOT FIND LEAKS, CHECK ACCUMULATOR PRESSURE VOLTAGE (3.5 V), DEPRESSED PEDAL 4-5 TIMES ACCUMULATOR PRESSURE DROPS BELOW 3.0 V, RECOMMEND REPLACE BRAKE/ABS ACTUATOR". OTHER NOTES, SOME PART OF HYBRID SYSTEM SEEMS TO BE CYCLING EVERY FEW MINUTES. OVER THE YEARS, WHEN BRAKING, THERE HAVE BEEN TIMES WHERE THEY "JUMP" OR DON'T GRAB DURING BRAKE PRESSURE AND AFTER READING HAVE FOUND THIS COMPLAINT WITH OTHER OWNERS. I SEE THAT THE CAMRY AND THE LEXUS HAVE BOTH HAD THIS PART RECALLED/REPLACED BY TOYOTA AND WONDERING WHY, WHEN THIS IS LIKELY THE SAME HYBRID SYSTEM AND COMPONENT, THAT TOYOTA WILL NOT STEP UP TO THE PLATE AND OFFER THIS REPLACEMENT PART FOR OWNERS FOR FREE OR AT A DISCOUNT? THE OTHER VEHICLES HAVE HAD ACCIDENTS AS A RESULT OF THIS PART AND TOYOTA SHOULD STEP UP TO THE PLATE ON THE HIGHLANDER HYBRID.

MY WIFE AND I WERE TRAVELLING ON I-95 (SOUTHBOUND) TOWARDS RICHMOND, VA. MY WIFE WAS THE DRIVER. WE WERE STEADILY TRAVELLING AT A SPEED... BETWEEN 65 AND 70 IN THE LEFT LANE (REQUIRED SPEED LIMIT). ALL OF A SUDDEN, WITH NO WARNING, THE PANEL LIGHTS STARTED BLINKING AND THE POWER TO THE CAR WAS SHUT OFF. MY WIFE WAS SCREAMING BECAUSE SHE WAS NOT ABLE TO CONTROL OR EFFECTIVELY APPLY BRAKES. SHE TRIED AND PULLED CAR OFF THE ROAD BARELY AND WE PUSHED IT OFF TO A SAFE SIDE. THIS COULD HAVE RESULTED IN A SERIOUS ACCIDENT IF WE WERE TRAVELLING IN THE MIDDLE LANE. THE CAR WAS LEFT OVERNIGHT AND TOWED TO TOYOTA DEALER. THE DEALER CALLED BACK AND GAVE A QUOTE OF $10000 BECAUSE THE HYBRID INVERTER HAVE TO REPLACED. I MENTIONED THE RECALL ON THE INVERTER. THE DEALER SAID THE RECALL DOES NOT COVER MY ISSUE. THERE IS A RECALL ON YOUR WEBSITE -WHAT ACTION OR RECOURSE DO I HAVE. THE ORIGINAL OWNER OF THE CAR REPLACED THE INVERTER AT 16200 MILES. EVIDENTLY ALL THE 2006 INVERTERS ARE DEFECTIVE. MY QUESTION IS THIS ---WHY YOUR DEPARTMENT IS TOYOTA TO GET AWAY WITH SUCH A SERIOUS DEFECT?

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.
