2012 TUNDRA 4.6 V8 MY TRUCK WILL GO INTO LIMP MODE AND THE 4LO LIGHT FLASHES, CHECK ENGINE, AND TRAC OFF LIGHTS WERE ALL ON. ALMOST COMPLETE LOSE OF POWER WILL HAPPEN. IN TRAFFIC I END UP BLOCKING EVER VEHICLE BEHIND ME, BECAUSE THE TRUCK WILL NOT REACH THE SPEED LIMIT. IF THERE IS A HILL THEN THE TRUCK BARELY MOVES GOING UP THE HILL. AFTER LOOKING ONLINE I SAW IT'S A PRETTY COMMON PROBLEM ON TOYOTA WITH THE SECONDARY AIR INJECTION PUMP SEIZING. I CHECKED IT WITH THE CODE READER AT A LOCAL SHOP AND THE GUY CONFIRMED IT, CODE P2240 "AIR INJECTION SWITCHING VALVE STUCK OPEN BANK 1." HE TOLD ME HE USED TO WORK FOR TOYOTA AND KNEW THERE WAS THE EXTENDED REPAIR ON THIS ISSUE BUT COULDN'T RECALL THE SPECIFICS. I WENT INTO TOYOTA AND UNFORTUNATELY THEY WILL NOT COVER IT FOR MY TRUCK AFTER THEY RAN MY VIN NUMBER. IT SEEMS LIKE A LOT OF TUNDRAS WITH THE 5.7L MOTOR ARE COVERED BUT THE 4.6L MOTORS ARE NOT. I WAS INFORMED BY TOYOTA THAT IN THE FUTURE IT MIGHT BE COVERED.

CHECK ENGINE AND TRACTION LIGHT CAME ON. 4LO SIGN FLASHED. VEHICLE GOES INTO LIMP MODE, SLOWING DOWN, AND AT TIMES CREEPING ALONG WHILE THE VEHICLE WAS IN MOTION ON THE HIGHWAY. THERE IS A LARGE DECREASE IN PERFORMANCE ESPECIALLY GOING UP ANY SORT OF INCLINE. TOOK IT TO THE TOYOTA DEALERSHIP FOR EVALUATION. THEY RECOMMENDED REPLACEMENT OF THE FUEL PUMP AND WAS TOLD TOYOTA IS AWARE OF THIS PROBLEM AND THIS MAKE/MODEL IS NOT PART OF THE RECALL AT THIS TIME. I CALLED THE TOYOTA HOTLINE, AND THE WORKER VERIFIED SHE COULD SEE INFO ON THE RECALL TALKING ABOUT WARNING SIGNS -BUT THEY WERE NOT SPECIFIC. SHE FORWARDED ON MY INFORMATION TO ANOTHER INDIVIDUAL. THAT INDIVIDUAL CALLED TODAY, AND SHE ADVISED MY WARRANTY WAS OVER AND MY VEHICLE WAS NOT INCLUDED IN THE RECALL.

WITH ONLY 81,719 MILES ON MY TRUCK I HAD TO HAVE THE AIR INJECTION PUMP & VALVES REPLACED ON 3/29/2019. I WAS INFORMED THAT THIS WAS A COMMON PROBLEM WHICH HAD BEEN RECALLED IN THE 2011 & 2010 MODELS. IF A RECALL IS MADE WITHIN A YEAR OF THE PART BEING REPLACED I WILL BE REIMBURSED. I WORK FROM HOME AND THE TRUCK HAS ONLY BEEN DRIVEN FOR LEISURE OR CHORES FOR THE PAST 3 YEARS. IT WAS DRIVEN DAILY IN LAS VEGAS FROM 2015-2017 AND IN ORLANDO FROM 2012-2015. THERE HAVE BEEN NO OTHER ENGINE PROBLEMS. IN JANUARY OF 2019 THE CHECK ENGINE LIGHT CAME ON AND THE CAR WAS PERFORMING WITH LESS POWER BUT EVERYTHING WORKED OKAY. INSTEAD OF DRIVING AN 8 CYLINDER TRUCK IT FELT LIKE DRIVING A FULL SIZE TRUCK WITH ONLY 4 CYLINDERS. THE ISSUE HAPPENED OVERNIGHT. EVERYTHING WAS FINE AND THEN THE PERFORMANCE JUST WENT SOUTH. I WAITED 2 MONTHS TO HAVE IT LOOKED AT BECAUSE I RARELY DRIVE AND BECAUSE IT STILL RAN BUT WITH LESS POWER. I WAS TOLD BY TOYOTA THAT IF ANOTHER MECHANIC FIXED THE PROBLEM AND A RECALL CAME LATER THEN I WOULD NOT BE REIMBURSED. AFTER I WAS INFORMED THAT THIS WOULD MORE THAN LIKELY BECOME A RECALL I MOVED FORWARD WITH USING TOYOTA'S SERVICE DEPARTMENT. MY GOAL IS TO FIND OUT IF THERE IS A RECALL PENDING FOR THE 2012 TUNDRA AIR INJECTION SYSTEM OR AT LEAST FIND OUT IF THE PROBLEM IS WIDESPREAD. IF I WAS TAKEN ADVANTAGE OF BY A DEALERSHIP USING THE RECALL AS A TACTIC TO GET MY BUSINESS I WANT TO MAKE SURE TO LET OTHERS KNOW SO I HOPE SOMEONE FROM THE NHTSA WILL FOLLOW UP.

A LIGHT CAME ON AND IT STARTED LOSING POWER. TOOK IT TO THE SHOP AND WAS TOLD IT WAS BAD GAS. I PUT THE CLEANER IN IT AND IT DIDN'T FIX IT. I HAD SOME BUDDIES TELL ME TO UNPLUG MY BATTERY BECAUSE IT SOUNDED LIKE A SAFETY FEATURE. SO I DID. THE LIGHT WENT OFF AND THE TRUCK ACTED RIGHT FOR A FEW MILES THEN STARTED DOING THE SAME THING. VEHICLE WAS IN MOTION ON THE HIGHWAY. MY BUDDIES REFERRED TO IT AS A "LIMP MODE" OR SOMETHING LIKE THAT. I WAS AFRAID TO HAVE IT WORKED ON BECAUSE I WAS TOLD IF THERE WAS A RECALL THE MANUFACTURER WOULDN'T BE LIABLE.

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.
