AT LESS THEN 50K MILES ON THE ODOMETER AND 900 MILES FROM HOME MY TRUCK DECIDED TO GET A CHECK ENGINE LIGHT AND TRAC OFF LIGHT CAUSED BY CODES P2440 AND P2442 AND P2445. MERRY CHRISTMAS TO ME. THESE CODES PUT ME INTO LIMP MODE WHILE ON THE FREEWAY IN SNOWY AND ICY CONDITIONS. I COULD NOT MAINTAIN SPEED WITH THE FLOW OF TRAFFIC AS I WAS TRYING TO GET TO THE SHOULDER WITH TRAFFIC ZOOMING ALL AROUND ME, DANGEROUS AND SCARY! TOYOTA WANTS $2000 TO REPAIR IT. INTERNET RESEARCH HAS SHOWN ME THAT IT IS A COMMON PROBLEM THAT TOYOTA FAILS TO RECOGNIZE FOR TACOMAS BUT HAS ISSUED A TSB AND EXTENDED WARRANTIES FOR TUNDRAS. SHAME ON TOYOTA. NOW I GET TO ENDURE THE COST OF REPAIR AFTER THE HOLIDAY SEASONS AND I'M SURE MY BOSS WILL LOVE TO HEAR I WONT BE RETURNING TO WORK ON TIME.

ALMOST LOST CONTROL OF VEHICLE WHEN THE TRUCKS PERFORMANCE JUMPED INTO LIMP MODE "TRAC OFF" AS I WAS DRIVING. LOSS OF SPEED AND PERFORMANCE CAUSED ME TO BE A DRIVING HAZARD. 2 VENDORS TODAY FOUND THE CODES P2440 AND P2442, WHICH APPEAR TO HAVE TRIGGERED MY TRUCK INTO "TRAC OFF" AND "CHECK ENGINE" LIGHT ON. MODE CAUSES MY TRUCK TO ONLY DRIVE ABOUT 45 SIGNIFICANTLY IMPACTS PERFORMANCE AND DANGEROUS TO DRIVE. THIS IS A SAFETY HAZARD,I HAD NO WARNING THAT THE LOSS OF PERFORMANCE WAS GOING TO HAPPEN INITIALLY WHEN I WAS TRAVELING.THERE IS ANOTHER PROBLEM THAT APPEARS TO BE ON A LARGER SCALE.I HAVE BRIEFLY SCANNED THE INTERNET IN THE LAST HOUR AND SPOKE WITH VARIOUS VENDORS ABOUT THE PROBLEM & I HAVE CALLED MY DEALERSHIP & EVEN THE MAIN TOYOTA LINE AND EVERYONE IS AWARE OF THE ISSUE. THE CODES ARE P2440 & P2442. AFTER FINDING OUT THE CODES I LOOKED AT THE AIR INJECTION PUMP & I WAS ASTONISHED TO SEE THAT THE PUMP WAS COMPLETELY FULL OF WHAT, LIKE SOMEONE LITERALLY TOOK A WATERHOSE & FILLED IT UP. LOGICALLY, THIS IS WHY THE AIR INJECTION SWITCHING VALVES 1 AND 2 ARE BOTH STUCK OPEN ONE CODE FOR EACH OF THE VALVES. THE NEXT THING THAT IS UNUSUAL IS THAT THERE ARE AN INCREDIBLE AMOUNT OF PEOPLE HAVING THIS SAME PROBLEM BUT NO RECALL..THEN I FOUND THE TUNDRA RECALL FOR THE EXACT SAME PUMP ISSUE! IT IS PECULIAR, THAT A DIFFERENT MODEL TRUCK WITH THE SAME PUMP HAS THIS PROBLEM & NO RECALL OR REMEDY. FACT-TUNDRA IS A MORE EXPENSIVE TRUCK THAN TACOMA, IS TOYOTA FIXING PUBLIC RELATION ISSUES FOR THOSE MORE WELL OFF BECAUSE THEY KNOW HOW TO COMPLAIN TO THE RIGHT FOLKS OR CAUSE A BIG STIR AND THEY WILL HOLD OFF ON PULLING THE TRIGGER ON A "WARRANTY FIX OR RECALL" ON THE WORKING MANS TACOMA? THIS IS JUST AN OPINION BUT MY INTUITION TELLS ME THIS IS INTENTIONAL. THE FIX IS APPROX $2000 I AM STUCK DRIVING 45 MPH TILL THEN WITH SHADY STEERING & PERFORMANCE. #ACCOUNTABILITY #ME TOO

SECONDARY AIR INJECTION SYSTEM FAILURE CAUSED MY VEHICLE TO ENTER LIMP MODE IN A HIGH SPEED/HIGH TRAFFIC AREA. "LIMP MODE" RENDERS THE VEHICLE INCAPABLE OF SPEEDS HIGHER THAN 30 MPH. CAUSING A HAZARD TO OTHER MOTORISTS, I EXITED THE HIGHWAY AS QUICKLY AS POSSIBLE. UPON RESEARCHING THE TOPIC I CAN PLAINLY SEE THIS IS SOMETHING THAT IS QUITE COMMON WITH MY PARTICULAR VEHICLE. HOWEVER, OTHER MODELS MADE BY THE SAME MANUFACTURER ARE BEING RECALLED AND REPAIRED WHILE THE MODEL I OWN IS NOT. IN ADDITION TO MODEL, THE YEAR OF MY VEHICLE SEEMS TO BE EXPERIENCING AN UNUSUALLY HIGH VOLUME OF FAILURES. FILING A COMPLAINT HERE IS ONLY APPROPRIATE AND APPROPRIATELY, THE AUTOMOTIVE MAKER SHOULD BE HELD RESPONSIBLE.

I WAS PULLING OUT ON TO THE HIGHWAY AND MY TRUCK FAILED TO EXCEED 30 MPH WITH ONCOMING TRAFFIC WHICH NEARLY CAUSED AN ACCIDENT. UPON INSPECTION BY MY TOYOTA DEALERSHIP, THEY EXPLAINED THAT MY SECONDARY AIR INJECTION VALVES WERE STUCK OPEN (P2440, P2442) WHICH CAUSED THE TRUCK TO LOSE ALL POWER. I WAS THEN TOLD THAT SINCE I AM NO LONGER UNDER WARRANTY (MY TRUCK IS ONLY 5 YEARS OLD WITH 48,000 MILES ON IT) THAT TOYOTA WOULD NOT COVER THE 2,000 DOLLAR COST TO HAVE THE PART REPLACED. UPON FURTHER RESEARCH, COUNTLESS OTHERS WERE HAVING THE SAME ISSUE. THE TOYOTA TUNDRA ALSO HAD THIS ISSUE AND AN EXTENDED WARRANTY WAS OFFERED FOR THOSE VEHICLES. SINCE TOYOTA KNOWS THIS IS AN ISSUE IT IS MY BELIEF THAT THEY SHOULD STAND BY THEIR PRODUCT AND FIX THE DEFECTIVE PART WHICH IS A HUGE SAFETY ISSUE AS I FOUND OUT. FURTHERMORE, THERE IS NO REASON THIS EMISSIONS PART SHOULD EVER SHUT DOWN THE POWER TO THE TRUCK WHILE DRIVING. THANK YOU FOR YOUR TIME.

1EA19001 · Electrical Overstress
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.
