2018 Toyota Avalon

The defect

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2011-2019 Corolla, 2011-2013 Matrix, 2012-2018 Avalon, and 2013-2018 Avalon Hybrid vehicles. During certain crashes, the air bag electronic control unit (ECU) may malfunction, possibly disabling the deployment of the air bags and/or seat belt pretensioners.

The risk

In the event of a crash, air bags and/or seat belt pretensioners that do not deploy as intended may increase the risk of injury.

The remedy

Toyota will notify owners, and dealers will inspect the ECU and install a noise filter between the air bag control module and its wire harness, as necessary, free of charge. Owners were notified of the safety risk beginning March 2, 2020. A second letter notifying owners of the remedy repair will be mailed between March 16, 2020 and June 27, 2020. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's numbers for this recall are 20TB03, 20TA03 and 20TA05.

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.

Date of safety issue: July 12, 2023 Location: Piper Glen Shopping Center, Rea Road, Charlotte NC (destination was Run For Your Life at 6416 Rea Road - within the shopping center). Time: Approximately sometime between 1:30 and 2:00 ET Police Report Complaint # - [XXX] On July 12, 2023 I entered a parking lot at a busy retail establishment. I chose a parking space that has a curb and bushes between the space and Rea Road. Due to the busyness of the parking lot it is imperative to drive slowly and cautiously. As I turned into the parking space the car suddenly accelerated, jumped the curb and crashed into the bushes. The brake did not stop the car until it jumped the curb. I then put the car …

Intermittently, unpredictably, for several seconds at a time, the engine almost quits, especially when accelerating So far, it has not happened in heavy traffic, but if it did, it would create a possibly major safety hazard. I have not taken it to a dealer yet. Just learned about the fuel pump problem that is associated with my 2018 Toyota Avalon. Plan to contact the dealer tomorrow. I have not seen any instrumental warning or notification. There is no warning that the engine is about to lose power and so far the engine has not stopped, but recovers to normal operation.. This has been occurring over the last couple of months. I fear for my wife's safety so that she will be unable to drive …

At approximately 42000 miles with no significant issues and no front end damages, the steering failed as I was driving at highway speed (70 mph) on a 2 lane road approaching a 90 degree curve. The power steering warning light and a separate triangle warning light appeared at the same time as I felt a pop and lost power and response in the steering wheel. Thankfully, I have driven heavy power equipment in the past and was able to control the vehicle to the shoulder and there was no surrounding traffic. I was able to proceed to my residence at a slow speed on the road shoulder with no power steering and an almost unresponsive steering wheel. After being towed to the local dealer, it was …
