MY RIGHT FOOT WAS ON THE BRAKE PEDAL, WHEN THE VEHICLE BEGAN TO ACCELERATE UNEXPECTEDLY AND HIT THE REAR OF VEHICLE STOPPED IN FRONT OF ME. AS I REALIZED THE COLLISION, I PRESSED THE BRAKE HARDER DELIBERATELY (WHILE THE CAR IN FRONT OF ME HAD STARTED TO MOVE FURTHER), AND TO MY HORROR MY CAR CONTINUED TO ACCELERATE DESPITE MY DEPRESSING THE BRAKE PEDAL. I CONSCIOUSLY CHECKED MY FEET TO ENSURE I WAS PRESSING THE BRAKES AND NOT THE ACCELERATOR. MY CAR CONTINUED TO STRANGELY & UNEXPECTEDLY ACCELERATE UNTIL IT HIT THE SAME CAR IN FRONT OF ME AGAIN THE 2ND TIME AT THE TRAFFIC INTERSECTION. AFTER THE 2ND COLLISION, MY CAR STOPPED AND I PULLED OVER TO THE SIDE OF THE MCQUEEN ROAD.

I WAS DRIVING ON A STRAIGHT HIGHWAY BETWEEN 45 -50 MPH. SUDDEN A BUNCH OF LIGHTS AND WARNINGS CAME UP IN THE DASHBOARD. I LOST POWER STEERING AND MOTOR PROPULSION TOO. I PRESSED THE ACCELERATOR AND NOTHING HAPPENED. ALTHOUGH I HAD THE ABILITY TO BRAKE, IT SEEMED THAT THE BRAKING WAS ALSO IMPAIRED. HOWEVER BECAUSE I WAS GOING UP AN INCLINE I DID NOT NEED STRONG BRAKING. I MANAGED TO COAST OVER TO THE BREAKDOWN LANE. LUCKILY THERE WERE ONLY A COUPLE OTHER CARS NEAR ME SO IT WASN'T TOO DIFFICULT TO MANEUVER BY THEM AND COAST TO THE OTHER SIDE OF THE ROAD WHERE THE BREAKDOWN LANE WAS. ONCE I WAS COMPLETELY STOPPED I SHUT THE CAR DOWN COMPLETELY AND RESTARTED IN THE NORMAL HYBRID STARTUP MANNER. THE CAR PROPULSION AND STEERING CAME BACK BUT NOW THE MESSAGE WAS ALTERNATING BETWEEN "MAINTENANCE NEEDED" AND "CHECK VSC SYSTEM", AND THE CHECK ENGINE LIGHT AND SYMBOL WAS ON. I SHUT OFF EVERYTHING ELECTRICAL TO MINIMIZE ELECTRICAL DRAIN. I WAS ABLE TO DRIVE THE CAR ANOTHER 8-10 MILES TO GET HOME BUT I WAS CONSTANTLY LOOKING TO SEE WHERE I COULD PULL OVER IF THE CAR STOPPED AGAIN. I MADE IT HOME. TOMORROW BRING IT TO THE TOYOTA DEALER. SIGNIFICANTLY, I RECENTLY HAD THE BRAKE ACTUATOR REPLACED AT A COST OF AROUND $2700, SPECIFICALLY BECAUSE THEY WARNED ME THAT I COULD LOSE BRAKING AND OTHER ELECTRONIC FACILITIES UNPREDICTABLY. I THOUGHT THAT EXPENSIVE REPAIR WOULD AVOID THIS. UNFORTUNATELY IT APPEARS THAT WHAT THEY WERE PREDICTING COULD HAPPEN DID HAPPEN, BUT AFTER THE REPAIR! I WAS ON A HIGHWAY WHEN THE CAR DIED BUT WITH NOT MUCH TRAFFIC AND AN EASY ACCESS BREAKDOWN LANE. HAD IT BEEN 10 MINUTES LATER I MIGHT HAVE BEEN ON A MUCH BUSIER HIGHWAY IN A PLACE WHERE A BREAKDOWN LANE IS MUCH HARDER TO REACH. THAT WOULD HAVE BEEN A DANGEROUS SITUATION. HAD IT BEEN DAYTIME AND IN A SAFER AREA I WOULD HAVE STOPPED AND CALLED FOR A TOW TRUCK. *TR

13V396000 · Hybrid Propulsion System: Inverter

Sep 4, 2013

Toyota is recalling certain model year 2006-2010 Highlander hybrid vehicles manufactured February 16, 2005, through July 29, 2010; and model year 2006-2008 Lexus RX400h vehicles manufactured February 23, 2005, through December 2, 2008. The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. 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.

Consequence & remedy

Consequence: 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 will notify owners, and dealers will replace the IPM free of charge. Owners may contact Toyota at 1-800-331-4331. Vehicles that had their IPM replaced under recall 11V-342 are not affected by this campaign.

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.

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.

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.
