On or about 8/21/23, we were driving from Vermont back to our home in New Jersey when the sound system started malfunctioning. First, we lost all sound (safety warnings, as well as radio). The sound returned and then cut out again repeatedly. Then, the speakers emitted loud (full volume) static and popping sounds despite the audio system being "off." At the time, we were driving at approximately 65 mph on a highway with our two young children. The noise was so loud that it was difficult to focus on driving. The static and popping sounds continued until we pulled over and shut the car off. These failures have continued and increased in frequency since that time. Our safety was put at risk in two ways: 1) all of the safety warnings were and are muted and ineffective and 2) a full-volume static/popping sound while driving at highway speeds could have caused an accident. Subsequently, we did the following: -Googled the issue and found a relevant Technical Service Bulletin published by Toyota in September 2020 that applies to our make/model and VIN. It is labeled T-SB-0086-20 and can be found here: [XXX] . This suggests the issue applies to multiple Toyotas. The Bulletin indicates the VIN number where the issued stopped -- suggesting Toyota took steps to fix it. There has been no recall related to this issue and we were never notified of this issue. The issue is apparently related to a defective amplifier. -Brought our vehicle to our local Toyota service center (Paul Miller Toyota of West Caldwell NJ). An employee there was able to reproduce and confirm the issue and recommended replacing the amplifier. -Called Toyota to report the problem and register a complaint given the safety issues, failure to notify us of the problem even though it was known to Toyota, and the cost of repair ($2640). There were no warnings, messages, or other symptoms of the problem prior to the failure on or about 8/21/23. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Hybrid Harness Malfunction. As reported on FaceBook by my wife to [XXX] of LIA Toyota: "Well my husband's RAV 4 wasn't safe and you knew it. And corporate knew it. You are in the business of saving lives by informing your customers when you find a defect in your cars. This faulty harness is dangerous. And the repair is costly and there aren't many of these parts available to make the repair. You put my husband and countless others in danger. Shame on you." Not only has the problem been confirmed: On May 11th, I received a letter from TOYOTA Motor Sales, USA, Inc. entitled, Certain 2019-2022 Model Year Rav4 Hybrid Vehicle (AWD Only) Coverage for High Voltage Floor Under Wire Harness and Rear Traction Motor Cable Corrosion CUSTOMER SUPPORT PROGRAM 22TE09 NOTIFICATION... There was a YouTube Video made by [XXX] about this problem A YEAR AGO entitled, "CableGate," AND an article at TorqueNews. (I have links if needed) The vehicle has been inspected and repaired by LIA Toyota in Rockland County. OVER $5,500 that I'm looking to get a FULL refund. LIA gave me back $1,000 for over-charging me. I want the FULL refund from Toyota Motor Sales, USA, Inc. A warning lamp/message appeared on May 6. I have emails, reports to corporate & screenshots of conversations with LIA service...all lasting almost 2 months. Toyota Motor Sales, USA, Inc. and LIA Toyota BOTH new of this problem a year ago BEFORE they sent out the letter. The letter states they would repair it for free if under 100,000 miles. I had 114,000, BUT...if I knew a year ago, I would have brought it in...UNDER the 100,000 miles, and got a FREE repair. Thank you for helping me get a full refund and for helping others with this same problem. USA Toyota owners NEED TO KNOW THIS!

There is a recall for the roof rails leaking water which can damage the air bags and electrical components. They will not fix the roof with new gaskets unless you actually see the water coming in. My concern is that it is leaking and I'm just not seeing it because the 110 degree weather. I do not want to be in an accident with my wife and kids in the car and have the air bags not work. They should fix the gaskets before it leaks and leads to further potential damage or even life threatening results(air bags being wet and not deploying). They will not fix my roof until it actually starts leaking even tho there is a recall in place. This is ridiculous.

PE21005 · Battery Hold Down Bracket Thermal Events
Opened Feb 25, 2021 · Closed Aug 12, 2024
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery
The Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE) to understand the contributing factors and frequency of vehicle fires originating from the battery region of the engine compartment in Model Year (MY) 2013-2018 Toyota RAV4 vehicles on 25 February 2021. At the time of opening, ODI attributed eleven allegations and additional EWR events to this PE. PE21005 focused on replacement batteries installed in the subject vehicles. No reported fire event identified in PE21005 involved the originally supplied 12V battery. The reported fires took place in vehicles known to contain aftermarket batteries or whose age exceeded the expected life of the original equipment battery. ODI identified battery dimensioning as it relates to the battery retention system (hold down bracket, radiator support bolt, J-hook, and battery tray) as the main factor set in the contact between the battery hold down bracket contacting the positive terminal of the 12V battery. The subject vehicles carried over the same battery tray and retention system from the prior generation (MY2006 – MY2012) of RAV4 vehicles. However, the subject vehicles were equipped with a dimensionally smaller battery (Group 35) than the prior generation (Group 24F). The smaller- length measurement in the Group 35 battery size in a battery tray originally designed to fit a Group 24F battery contributed to increased potential for battery movement which was exacerbated by the diversity in aftermarket battery configuration and irregularities intrinsic to battery replacement procedures. Battery movement coupled with the proximity of the B+ terminal on the battery and the grounded electrically conductive hold down bracket set the stage for a short to ground leading to an engine stall (if in operation) followed by a vehicle fire. This investigation was not able to classify the installation status, battery size, or cause of every allegation due to the fire event causing damage to the area, inaccessible vehicle, modification to the battery retention system after the event, and/or inconclusive photographic evidence. Toyota's investigation of the issue identified aftermarket battery catalogs that listed an improper battery replacement size (Group 26R) that would nevertheless fit into the subject vehicles whose battery retention system is incapable of reliably restraining a Group 26R battery. On 18 November 2021, Toyota initiated a consumer advisory campaign (21TG01) to the subject vehicle owners, notifying them of the correct size battery and offering a free inspection of the battery and retention hardware, a caution label to affix to the hold down bracket, and a discounted replacement 12V battery. This investigation with Toyota established three broad categories to characterize the battery retention system state of a given vehicle: "correct", "minor mis-installation", and "major mis-installation". - The "correct" terminology references the front bolt, bracket, and J-hook installed in a position not in contact with the positive battery terminal and the front bolt torqued to 17 Nm and the J-hook engaged with the tray hole and torqued to 4.9 Nm. - A "minor mis-installation" would describe the three retention components installed in the prescribed location, however not to the correct torque values. - The "major mis-installation" condition would constitute a retention component missing or disconnected from the system. Toyota's own testing used five exemplar batteries installed on a subject vehicle in each battery categorization resulted in: - Contact between the B+ terminal and hold down bracket in "major mis-installations" - Movement of the battery in "minor mis-installations" - No observable motion in "correct" installations. ODI conducted its own evaluation of the Toyota- specified replacement battery and 5 aftermarket Group 35 batteries. The six batteries tested conformed to the Group 35 Battery Council International (BCI) standard on overall dimensional tolerance and terminal location. That standard does not define the edge shape or material of battery casing. Physical interaction between the hold down bracket and the battery case and the friction between the casing material and the battery tray resulted in a large variability in movement forces required to incite movement when the battery was installed in the "correct" condition. Resulting in movement at an induced lateral load between 0.6 G and 1.91 G equivalent force across each battery. This force is higher than a typical vehicle could exert in a steady state turn and would only experience loads through brief shock or impulses. Multiple shock or impulse loads across time would contribute to a delay between the replacement battery installation and the fire event. Likelihood of a fire event increases as the installation method degraded from the "correct", to "minor mis-installation", and then to "major mis-installation". Protruding vent caps atop some of the batteries tested aided in restricting battery movement relative to the hold down. An absence of vent caps permitted additional movement. Following several discussions and vehicle inspections with ODI during this investigation, on 01 November 2023, Toyota filed a safety recall (NHTSA 23V-734) of 1,853,568 MY 2013 through MY 2018 Toyota RAV4 vehicles to reduce the risk of a vehicle fire with redesigned battery retention components.

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.

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.

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).
