The defect

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2012 Toyota Avalon vehicles. During a vehicle repair, the seat belt inner buckles may have been replaced with parts that may incorrectly tell the air bag management system that the seat belt is always buckled.

The risk

If the seat belt is falsely interpreted as being buckled, in the event of a crash, the air bags may not deploy appropriately, increasing the risk of injury.

The remedy

Toyota will notify owners, and dealers will test the seat belt assembly to verify that it is properly detecting being unbuckled, replacing the inner seat belt assembly as necessary, free of charge. The recall began September 19, 2018. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is J0S.

The defect

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2011-2012 Toyota Avalon vehicles manufactured February 9, 2010, to October 22, 2012. In the affected vehicles, the sub-woofer speaker located in the trunk may experience an intermittent electrical short which may cause damage to the integrated circuit (IC) in the audio amplifier. In some cases, the damaged IC may allow a constant electrical current flow to the sub-woofer.

The risk

A constant electrical current flow may cause the sub-woofer to overheat, increasing the risk of fire.

The remedy

Toyota will notify owners, and dealers will replace the audio system amplifier and install a protective cover around the sub-woofer, free of charge. The recall began on July 1,2015. Owners may contact Toyota customer service at 1-888-270-9371.

The defect

Toyota is recalling certain model year 2012-2013 Avalon, Avalon HV, Venza, Camry, and Camry HV vehicles. In the affected vehicles, the drain hose for the air conditioning condenser may become clogged causing water to accumulate at the bottom of the air conditioning condenser unit housing. The accumulated water may then leak through a seam in the housing onto the air bag control module potentially resulting in a short circuit of the module.

The risk

A short circuit may cause the air bags to become disabled or inadvertently deploy. An inadvertent airbag deployment can increase the risk of injury or the possibility of a crash. An inoperative airbag can increase the risk of injury in a severe crash. The power steering assist could also become inoperable resulting in increased steering effort and can increase the risk of a crash at low speeds.

The remedy

Toyota will notify owners, and dealers will seal the air conditioning condenser unit housing and install a protective cover on the airbag control module, free of charge. The recall began on February 5, 2014. Owners may contact Toyota at 1-800-331-4331.

the air bags

The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect.  During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW.  The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications.  The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU.  In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment.  FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle.  Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW.  These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes.  An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time.   In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU.  This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners.  Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW.  The risk associated with the ASIC is equally shared among all OEMS involved in the investigation.  The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage.  There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation.  The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU.  If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC.  Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC.  All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled.  In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024.  With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.

While entering the highway on ramp, as I accelerated and turned on the left turn signal, the engine stopped. The steering became very hard. I stopped, put the transmission in park and started the engine, with no problems. This is the second time in3 months this has happened when turning to the left, and activating the turn signal. In both cases, the auto headlight dimming warning lite came on. The car is well maintained, and has never been damaged in any way. The weather was clear.

There is a rear windshield shade that comes up automatically during a bright or hot day. It has a button to manually bring it up or down also. Just last month the gear inside the shade is broken and it does not come down. If I manually put it down it will come up automatically when driving, causing a loud noise distracting the driver even though, the driver has not pressed the button to pull it up. Now it is stuck in up position causing loud noise when reversing. And the biggest safety issue that I see is the night driving. Since the shade is up and I cannot make it go down, the visibility in the rear view mirror is very poor or nothing. There is no way for the driver to let it stay in the …

ANOTHER DRIVER RAND A RED LIGHT AND I (T-BONED HIS PASSENGER SIDE) WAS IN A HEAD ON COLLISION. I WAS BREAKING AT THE TIME, BUT STILL IMAGINE I HIT HIM AT BETWEEN 30-40 MPH. THE FRONT END CRUMPLED AS EXPECTED BUT THE AIRBAGS DID NOT DEPLOY. FIREFIGHTERS CUT POWER TO PREVENT THE AIRBAGS FROM DEPLOYING UNEXPECTEDLY AFTERWARDS. A CHECK PASSENGER AIRBAG LIGHT HAD COME ON IN RECENT DAYS THAT I DID NOT GET FIXED BEFORE THE ACCIDENT, BUT IT SHOULD NOT HAVE AFFECTED THE DRIVER SIDE AIRBAG I EXPECT. LIBERTY MUTUAL IS CURRENTLY IN POSSESSION OF THE CAR (THEY DEEMED IT A TOTAL LOSS).
