We are a surveying company with a fleet of 35 Toyota Tundra trucks. Two of the trucks in our Denver location have had the engine wiring harness chewed and destroyed by rodents in the parking lot. Each is costing $6,500 to repair. The second truck shorted out and the check engine lights came on, would not start. I am glad this did not fail while someone was driving it. Toyota uses a flexible pipe wrap over some of this wiring that is soy based; the plastic wrapped wiring is unaffected. This problem is well documented on the internet, and very common. Toyota is profiting in a big way from this design defect, and they are compromising safety by risking engine failures due to shorts. They should be forced to install hard plastic wire covers over these harness wires to prevent this damage.

ON TWO DIFFERENT OCCASIONS I WAS DRIVING MY TUNDRA ON THE FREEWAY AT APPROX. 70 MPH. MY TRUCK LOST POWER AND I ALMOST CAUSED ACCIDENTS ON BOTH INSTANCES SINCE I COULD NOT ACCELERATE PAST 40 MPH. I HAD TO MANAGE MY WAY OUT OF THE FREEWAY TO A SAFE PLACE. 2TWO DIAGNOSTICS WERE PERFORMED AND I RECEIVED CODES P0418, P1604, C1241, P2445, P2441. I WAS TOLD BY THE TOYOTA DEALERSHIP THAT THERE WAS A PROBLEM WITH A FAULTY SECONDARY AIR INJECTION SYSTEM PUMP AND OTHER COMPONENTS RELATED TO THE SYSTEM AND I WAS PROVIDED A REPAIR COST OF OVER $3,000 DOLLARS. I WAS LATER INFORMED, AND I DISCOVERED THROUGH RESEARCH, THAT TOYOTA HAD INSTALLED FAULTY/DEFECTIVE AIR PUMPS IN THOUSANDS OF TUNDRAS 2013'S LIKE THE ONE THAT I OWN. I REACHED OUT TO CORPORATE OFFICE BUT THEY STATED THAT MY VIN NUMBER SOMEHOW DID NOT "QUALIFY" AS ONE OF THE AFFECTED PICKUPS. MY TUNDRA ONLY HAS 60K MILES AND I USE IT TO COMMUTE FROM AND TO WORK BASICALLY. I PERFORM ROUTINE MAINTENANCE. THERE IS OBVIOUSLY A PROBLEM WITH A DEFECTIVE SECONDARY AIR PUMP SYSTEM THAT TOYOTA REFUSES TO FIX. MY TRUCK IS A LIABILITY ON THE ROAD AND THIS IS MY ONLY MEANS OF TRANSPORTATION. IT LOOSES POWER AND THE CHECK ENGINE LIGHT ACTIVATES. TOYOTA RECALLED THOUSANDS OF VEHICLES LIKE MINE AND FIXED THEM AFTER THEY ACKNOWLEDGED THAT THEY HAD PLACED FAULTY AIR PUMP SYSTEMS. MY TRUCK IS A POTENTIAL POSSIBLE CAUSE FOR AN ACCIDENT SINCE IT UNPREDICTABLY LOOSES POWER ON THE FREEWAY. I HAVE NOT RECEIVED A SOLUTION FROM HEADQUARTERS/CORPORATE OFFICE TO REPAIR MY TRUCK AT NO PRICE SINCE IT IS AFFECTED BY THEIR FAULTY PUMPS. THEY DID OFFER $750 DOLLARS TOWARDS THE COST OF PARTS, MEANING THAT I HAVE TO COME OUT WITH OVER $2000K OUT OF POCKET. I NEED TOYOTA TO TAKE RESPONSIBILITY AND FIX MY TRUCK.

INITIALLY DRIVER SIDE LOCK ACTUATOR WOULD NOT UNLOCK DOOR VIA REMOTE. THIS LAST APPROXIMATELY 10-DAYS. THE PROBLEM RESOLVED IT SELF. APPROXIMATELY 2-WEEKS LATER THE FRONT PASSENGER DOOR EXHIBITED THE SAME PROBLEM. THE PASSENGER DOOR LOCK ACTUATOR PROBLEM LASTED APPROXIMATELY 7-DAYS. THIS HAS BEEN RANDOMLY HAPPENING OVER THE PAST 6-8 MONTHS. WITHIN THE PAST 5-DAYS THE DRIVERS DOOR BEGAN ACTING UP. THIS TIME THE LOCK WOULD UNLOCK USING THE REMOTE BUT THEN WOULD NOT LOCK USING THE REMOTE. I WOULD HAVE TO CYCLE THE LOCK SYSTEM 4 TO 5 TIMES BEFORE ALL FOUR DOORS WOULD LOCK USING REMOTE. AT SOME TIMES THREE OF THE FOUR DOORS WOULD LOCK EXCEPT THE DRIVERS DOOR. I THEN TRIED TO RECYCLE THE LOCK SYSTEM. AT TIMES AFTER RECYCLING THE LOCK SYSTEM I WOULD STILL HAVE TO LOCK DRIVERS DOOR MANUALLY. I TOOK VEHICLE TO TOYOTA DEALER IN MY HOMETOWN, THE DIAGNOSIS WAS THAT BOTH FRONT DOOR LOCK ACTUATORS ARE BAD AND I WOULD NEED TO SPEND $1,200 TO FIX. I WAS TOLD THE LOCK ACTUATORS ARE NOT COVERED UNDER ANY MANUFACTURES RECALL. THE LOCK ACTUATOR ISSUE HAS ALWAYS HAPPENED WHEN VEHICLE IS IN A PARKED CONDITION, ENGINE OFF. IT HAS HAPPENED IN ALL KINDS OF WEATHER.

Opened Apr 19, 2019 · Closed Sep 19, 2024

Status: closed (inferred from source dates) · Air Bags: Air Bag/restraint Control Module

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.
