TAKATA RECALL. ALL OF THE DOORS ON MY 2014 RAV4 LOCK AND UNLOCK WHEN THEY CHOSE TO. NORMALLY WHEN THE CAR IS IN DRIVE THE DOORS ALL LOCK HOWEVER AS OF JANUARY 2019 THEY HAVE BEEN LOCKING AND UNLOCKING WHEN THEY DECIDED TO WORK. USING THE EXTERNAL KEY BUTTON TO LOCK AND UNLOCK THE DOORS WORKING MAYBE 50% OF THE TIME ON ABOUT 2 TO 3 OF THE DOORS. THE SAME GOES FOR THE INTERNATIONAL LOCK BUTTONS AND WHEN THE CAR IS SHIFTED INTO DRIVE. THIS IS EXTREMELY DANGEROUS FOR ME AND MY CHILDREN WHO I AM NOT TERRIFIED TO HAVE IN MY CAR. SHOULD THE DOORS CHOSE TO NOT LOCK AND THEY ACCIDENTALLY PULL THE DOOR OPEN IT WOULD BE A HORRIFIC ACCIDENT. AND MY YOUNGEST HAS A PANIC ATTACK WHEN I GO TO GET HIM FROM THE CAR BUT CANT BECAUSE THE DOORS NEVER UNLOCKED WHEN WE PARKED. PLEASE FIGURE THIS PROBLEM OUT I LOVE MY RAV BUT IT IS NOT SAFE RIGHT NOW.

THE RADIO/INFOTAINMENT SYSTEM ON THESE VEHICLES ARE FAILING (OURS FAILED LAST WEEK), WITH NUMEROUS EXAMPLES POSTED BY OWNERS ONLINE. A DEALERSHIP EVENTUALLY DETERMINED THAT THE ENTIRE RADIO UNIT NEEDED REPLACEMENT AT QUOTED COST OF $1160 TOYOTA CUSTOMER SUPPORT IS COURTEOUS BUT UNWILLING TO ASSIST WITH REPAIRS. THE RADIO SYSTEM APPEARS TO ENTER A BOOT LOOP WHERE A LOADING TYPE SCREEN APPEARS FOR SEVERAL SECONDS FOLLOWED BY THE SCREEN TURNING OFF FOR A TIME BEFORE RESTARTING THE LOOP. WHILE I WOULDN'T CONSIDER THE RADIO/INFOTAINMENT TO BE A CRITICAL SAFETY COMPONENT, THIS CONSTANT ON/OFF OF THE RADIO SCREEN IS A DISTRACTION FOR THE DRIVER. AT NIGHT ESPECIALLY, THE CHANGE IN BRIGHTNESS FROM SCREEN OFF TO SCREEN ON LIGHTS UP THE ENTIRE CABIN. FURTHERMORE, THE BOOT LOOP CANNOT BE STOPPED- NO BUTTONS WORK AND THE SEQUENCE REPEATS ITSELF FOREVER AS LONG AS THE KEY IS ON.

WHEN I HAD MY CAR IN PARK MY STEREO STOPPED WORKING. NO RADIO, NO SATELLITE, NO NOTHING OTHER THAN BACK UP CAMERA. WHEN I START THE CAR I GET A BLUE PICTURE OF THE STEREO AND A STATUS BAR LOADING LIKE ON COMPUTERS WHEN A PROGRAM IS LOADING. I TOOK THE CAR TO THE TOYOTA DEALER AND HE EXPLAINED THAT THE REPLACEMENT WOULD COST 2,500 DOLLARS TO REPLACE AND HE EXPLAINED THERE WAS NO MEANS TO FIX IT. I WENT TO ANOTHER MECHANIC AND HE TOLD ME THE SAME THING. I HAVE HAD THE CAR FOR ONLY 1 YEAR AND 6 MONTHS WITH 45000 MILES AND IT JUST SUDDENLY STOPPED WORKING. I BELIEVE THERE IS A DEFECT IN THESE RADIOS THAT CAUSE THIS ENDLESS LOOP TO OCCUR. MANY OTHERS HAVE EXPERIENCED SIMILAR PROBLEMS WITH THE SAME MODEL OF CAR AS WELL.

WHILE TRAVELING WESTBOUND ON INTERSTATE 295 IN JACKSONVILLE FLORIDA, WE HAD JUST GOT ON TO THE BUCKMAN BRIDGE WHEN THE CAR SLOWED, UNCOMMANDED TO 20MPH. I LOOKED AT THE INSTRUMENT CLUSTER AND THE ALTERNATOR AND THE AUTO LSD OR TRACK LIGHTS WERE ILLUMINATED. THE ENGINE OPERATING TEMPERATURE WAS NORMAL. SINCE THE ENGINE TEMPERATURE WAS NORMAL I TOLD MY DAUGHTER TO KEEP DRIVING TO GET OFF THE BRIDGE, I FELT AS THOUGH THE BRIDGE WAS A BAD PLACE TO PULL OVER. AFTER ABOUT A MINUTE WE STARTED TO SMELL SOMETHING BURNING AND AT THIS POINT WE DECIDED TO PULL OVER. WHEN WE CAME TO A COMPLETE STOP WE SAW SMOKE COMING FROM THE DRIVERS SIDE OF THE ENGINE COMPARTMENT. THREE OF US THEN EVACUATED THE VEHICLE AND STARTED WALKING AGAINST TRAFFIC ON THE BRIDGE. AS WE WERE WALKING AWAY THE SMOKE INTENSIFIED AND THEN ERUPTED INTO FLAMES THAT EMANATED FROM THE DRIVERS SIDE JUST BELOW THE WINDSHIELD. I CALLED 911 AND THE FIRE DEPARTMENT CAME AND EXTINGUISHED THE FIRE. I HAVE ATTACHED PICTURES OF THE DAMAGE. I BELIEVE IT WAS AN ELECTRICAL FIRE.

ISSUE FIRST STARTED WHEN BATTERY HAD TO BE JUMPED. THEN A FEW DAYS LATER WHEN IN MOTION DRIVING TO THE BANK, THE RADIO STARTED ACTING UP AND GOT STUCK ON STATION AND SONG AND THEN JUST WENT BLACK THEN A PICTURE OF THE RADIO APPEARED THE ON THE SCREEN AND WAS ATTEMPTING TO UPDATE BUT WOULD GO BLACK AGAIN AND THEN START OVER SO WAS STUCK IN SOME KIND OF REBOOT. NOT SURE IF ELECTRICAL PROBLEM OR WHAT SO TOOK IT IN TO DEALERSHIP AND THEY TOLD ME I SHOULD ONLY HAVE TO PAY $50-60 TO REBOOT IT. THEY CHECKED THE BATTERY AND SAID THE BATTERY WAS LOW CHARGE AND REPLACED IT AT NO CHARGE BUT SAID THEY WERE UNABLE TO REBOOT THE SYSTEM BECAUSE IT WOULD NOT STAY UP LONG ENOUGH BEFORE IT WOULD BLACK OUT AGAIN. SINCE IT WAS BARELY PAST THE WARRANTY PERIOD TOYOTA WOULD NOT COVER THE SYSTEM AND I WOULD HAVE TO PAY $1000 TO HAVE REFURBISHED SYSTEM INSTALLED. AFTER RESEARCHING ONLINE I FOUND THIS WAS A COMMON COMPLAINT AND FOUND ONE HERE AT THIS SITE AS WELL SO ADDING MINE. I SENT LETTERS AND EMAILS TO TOYOTA TO STAND BEHIND THEIR LONG TIME CUSTOMERS AND PRODUCTS BUT THEY WOULD NOT BUDGE. MULTIMEDIA SYSTEMS SHOULD NOT FAIL AFTER 3 YEARS. I CALL THAT A DEFECT BUT I GUESS BECAUSE IT IS NOT CONSIDERED A SAFETY ISSUE IT IS NOT IMPORTANT TO TOYOTA. WE ARE A TOYOTA FAMILY AND HAVE BEEN DRIVING TOYOTA'S SINCE MY FIRST CAR BACK IN THE 70'S. I WILL PROBABLY GO AHEAD AND REPLACE WITH REFURBISHED SYSTEM HOPING THIS IS NOT AN ELECTRICAL ISSUE AND REPEAT BUT I WILL CERTAINLY RECONSIDER BEFORE PURCHASING ANOTHER TOYOTA IN THE FUTURE.

1PE21005 · 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.
