Fuel/Propulsion SystemFeb 2024 · ODI 11571836Details +

The fuel pump failed on my Tundra. Several dashboard check engine lights suddenly lit up to warn me of the issue. While I was able to safely get it to a mechanic to repair the independent Toyota certified mechanic I use shared they have seen a volume of these where the car stops immediately with the Fuel pump failing completely. I was lucky as the day prior to this I was driving through mountain passes on the highway in Colorado. I have since found out from the feedback from my mechanic that they have repaired a volume of these, and it is a known issue by Toyota who issued a technical service bulletin. The fuel pump needs to be replaced with a different specification - the original pump is not sufficient. My concern is putting driver/passenger safety at risk with a complete fuel pump failure while driving. I consider this a near-miss for me, and would worry about others that are about to have this issue.

My power steering gear blew its seal on the passenger side losing all power steering fluid and almost making me crash into a car next to me, and Toyota refuses to cover it stating that I hadn't had the steering gear replaced prior to whenever their dates were this is clearly faulty equipment and faulty machine work on the steering gear itself. why won't Toyota cover it? I tried contacting One Toyota and Downtown Toyota here in Oakland California and they told me that they wanted $250 to inspect my vehicle and that I would definitely have to pay for it because my vehicle was not under recall it states it is a recall if you look it up.It is worded recall if they're not going to cover it sounds like they're trying to back out of covering it until someone gets seriously hurt or killed like I almost did, I will never buy another Toyota again as long as I live because clearly they don't care about the faulty equipment on their vehicles that's going to hurt or kill someone. All they care about is the mighty dollar and that's just wrong. Safety has gone rite the window and if anyone reading this is thinking about buying a Toyota, I would seriously think twice.

Secondary air injection system failed May 2019. ALL dash warning lights came on. Researched on-line and found truck would not have accelerated past “limp mode” (25-30 mph). Had to have vehicle towed to local Toyota dealer as I was over 40 miles from home (all highway). Toyota dealer diagnosed secondary air injection system failure. Cost to repair OVER $3000. Toyota has acknowledged this is a KNOWN design problem on the Tundra “big” V8s but refuses to recognize this is a design problem on the 2012 4.6L V8 models. Local dealer stated “we have lots of these lying around the shop so no problem getting the part.” Indicating this is a common problem/repair. Spoke directly with Toyota Corporate office who refused to acknowledge design fault or reimburse for repair. This is a HUGE safety issue caused by a known Toyota design problem that needs to be investigated by NHTSA. Toyota MUST be help accountable for this problem and made to correct the problem with a "recall".

The horn can not be operated by the steering wheel. The horn still works when the panic alarm is pressed. According to several forums that I have visited, it’s a common issue with the steering column rubbing the insulation off of the wire. I believe that if this is that common of an issue, it should be reported, and hope that it will be addressed by a recall.

Secondary air injection system failed June 2018. Vehicle went into limp mode on highway, a dangerous situation as you go from 70 to 30 MPH rather suddenly. Alamo Toyota dealership in San Antonio stated code PO418 and needs to have air pumps and valves replaced. Cost estimate of $3362.57. Toyota has acknowledged this is a design problem on certain Toyota Tundras but fails to recognize this is an issue on the 2012 4.6L V8 models. Toyota needs to take responsibility that this is still an issue with the 2012 4.6L V8 models.

Check engine light which when checked revealed Air pump and air control valve failures. This is a known problem with 2006-2011 Tundras that Toyota issued an extended warranty for 10 years or 150,000 to replace these parts. There was additional extended warranty for 2012 with 5.7 Liter engine but not the 4.6 liter engine. Safety issue is when total failure occurs vehicle goes into limp mode with max speed of 25MPH which would be bad at highway speeds. Code was run by repair facility and copy is enclosed.

TOYOTA MOTOR CO KNOWS ABOUT THIS ISSUE IN ALL THEIR 5.7L ENGINES AND THAT ITS A FACTORY ROBOT ERROR BY NOT APPLYING ENOUGH SEALANT IN THE GASKET. AND THIS IS JUST BEING FIXED IF YOU ARE EITHER UNDER FACTORY WARRANTY OR EXTENDED WARRANTY. THE VEHICLES LOOSE POWER AND IF DRIVING ON A HIGHWAY CAN CAUSE A MAJOR ACCIDENT. THE LEAST THIS COMPANY CAN DO IS OFFER A VOLUNTARY RECALL BUT THEY ARE REFUSING TO DO SO BECAUSE THE FIX WILL COST THEM $3500-$4000 FROM ALL THEIR 5.7L ENGINES ASSEMBLED IN THE U.S. SO FOR MY SAFETY AND THE SAFETY OF MANY TOYOTA DRIVERS AND GENERAL HIGHWAY DRIVERS SAFETY, I HOPE THIS WOULD BE TAKEN INTO CONSIDERATION.

THE TRAC OFF LIGHT AND CHECK ENGINE LIGHT CANS ON AT THE SAME TIME. I TOOK IT TO TOYOTA AND THEY SAID THERE WAS AN EXTENDED WARRANTY OF 10 YEARS OF 150,000 MILES. IF IT WAS THE SECONDARY VALVES AND AIR PUMPS. I GOT A CALL BACK AND THEY SAID IT WAS, BIG MY VIN WAS NOT PART OF THE EXTENDED WARRANTY. THIS IS AN ISSUES WITH 100S OF TUNDRAS. THIS IS A SAFETY ISSUE. BECAUSE YOU CAN'T GO OVER 60 OR GET TO 60 SAFELY. THE TOYOTA BLOGS ARE FULL OF TUNDRA OWNERS COMPLAINING. THIS NEEDS TO BE FIXED.

MY 2012 TUNDRA HAD A TRAC OFF AND ENGINE LIGHT COME ON. THIS IS THE SAME PROBLEM FOR NUMEROUS TOYOTA TUNDRA IN REGARDS TO FAILURE OF THE SECONDARY AIR VALVES AND PUMPS. I WAS TOLD MY VIN NUMBER WAS NOT ON THE 10 YEAR , 150,000 MILE WARRANTY FOR THIS SAME PROBLEM. I URGE YOU TO FORCE TOYOTA TO ADD MY VIN NUMBER TO THE EXTENDED WARRANTY. MY VEHICLE CANNOT GO OVER 60 AND BE SAFE. IT WAS RAINING AND RAIN GOT INTO THE PUMP SYSTEM. TOYOTA HAS REPLACED THOUSANDS OF THESE BADLY DESIGNED SYSTEM AND MORE NEEDS TO BE DONE. IT COST OVER $2,000 TO REPLACE BADLY DESIGNED SYSTEM.

2012 TOYOTA TUNDRA 4.6 L AT 101,000 MILES WENT INTO LIMP MODE CAUSING A LACK OF POWER AND ACCELERATION DURING CITY DRIVING WHICH COULD HAVE RESULTED IN A REAR END COLLISION. WAS ABLE TO LIMP VEHICLE TO NEARBY TOYOTA DEALER WHO DIAGNOSED THAT THE SECONDARY AIR INJECTION SYSTEM WAS FAULTY. COST TO REPAIR WAS MORE THAN I WANTED TO PAY BEINGTHAT I HAD JUST PURCHASED THE TRUCK WITHIN THE PAST MONTH OR SO. TOYOTA DID NOT COVER THE REPAIR SO A BYPASS KIT WAS INSTALLED AT MY EXPENSE TO GET THE TRUCK BACK UNDER POWER. CONTACTED TOYOTA AND THEY ADVISED THAT THE SYSTEM WAS NOT COVERED HOWEVER IT SHOULD BE NOTED THAT ON 2010 MODELS AND OTHERS THE WARRANTY ON THE SYSTEM WAS EXTENDED TO 150,000 BUT NOT ON THE 2012 4.6L ENGINES THAT HAVE THE SAME PROBLEMS AS THE OTHERS.

WHEN IN MOTION THE VEHICLE ENTERS LIMP MODE AND LOSES POWER. ACCELERATION BY PEDAL DOES NOT FUNCTION, THE ENGINE ONLY REVS AND DOES NOT SPEED UP. THE VEHICLE SLOWS DOWN TO ANYWHERE FROM 25 TO 5 MILES PER HOUR ON ITS OWN WITHOUT STEPPING ON THE BRAKE AND THE TRANSMISSION DOESN'T SHIFT. THIS HAPPENS ANYWHERE, HIGHWAY, STREET, DRIVING STRAIGHT, TURNING, ETC. NO WARNING. I ALMOST GOT REAR ENDED BECAUSE THIS PROBLEM EQUATES TO SOMEONE DRIVING ON THE HIGHWAY AND SLAMMING ON THEIR BRAKES WITH NO BRAKE LIGHTS!! I COULD HAVE LOST MY LIFE TODAY!

MY 2012 TUNDRA WITH 107K DISPLAYED THE CHECK ENGINE, 4LO, AND TRACTION CONTROL WARNING LIGHTS AND WOULD ONLY DRIVE IN 'LIMP MODE'. LUCKILY THIS HAPPENED AT STARTUP WHEN I WAS LEAVING WORK ONE AFTERNOON, AND NOT AS I WAS DRIVING AT HIGHWAY SPEED. I 'LIMPED' TO THE LOCAL DEALER USING BACK ROADS AND LEFT THE TRUCK FOR DIAGNOSIS. I WAS NOTIFIED THAT THE TRUCK WAS EXHIBITING CODE 'P2440' FOR A FAULTY SECONDARY AIR INJECTION SYSTEM VALVE, AND THAT BOTH SECONDARY AIR PUMPS AND VALVES WOULD NEED TO BE REPLACED TO CORRECT THE ISSUE. THE REPAIR WOULD COST $2500, BUT "LUCKILY" THE DEALER HAD THE PARTS IN STOCK BECAUSE THIS WAS A COMMON PROBLEM. SINCE I NEEDED THE TRUCK TO GET BACK AND FORTH TO WORK EACH DAY, AND I AM NOT READY TO REPLACE IT, I AUTHORIZED THE REPAIR AND PICKED IT UP THE NEXT DAY. SUBSEQUENT RESEARCH ON-LINE SHOWED THAT THIS HAS BEEN A KNOWN ISSUE FOR YEARS. TOYOTA EXTENDED THE WARRANTY ON THESE PARTS FOR MY 2007-2011, AND LATER FOR CERTAIN 2012 VEHICLES AS WELL. UNFORTUNATELY, IT APPEARS THAT ONLY THE 2012S WITH THE 5.7L ENGINE ARE COVERED (MINE IS A 4.6L). FROM MY RESEARCH, IT SEEMS THAT THE PUMPS/VALVES IN MY TRUCK ARE THE EXACT SAME PARTS THAT ARE KNOWN TO FAIL (AND ARE COVERED) IN OTHER MODEL YEARS. I CALLED TOYOTA CUSTOMER SERVICE, AND OF COURSE THEY ADVISED THAT THEY WOULD 'LOG' THE ISSUE AND CONTACT ME SHOULD THE WARRANTY BE EXTENDED TO COVER MY TRUCK. JUDGING BY THE NUMBER OF COMPLAINTS HERE, I FEEL THAT IT WARRANTS AN INVESTIGATION AND PERHAPS APPLYING SOME 'EXTERNAL' PRESSURE TO PERSUADE TOYOTA TO DO THE RIGHT THING AND COVER ALL OF THE AFFECTED VEHICLES. NOT ONLY IS THIS AN EMISSIONS ISSUE, BUT COULD BE A SERIOUS SAFETY ISSUE IF THE TRUCK WERE TO GO INTO LIMP MODE WHILE DRIVING. *TR

ON NUMEROUS OCCASIONS WHILE DRIVING, MY 2012 TOYOTA TUNDRA SUDDENLY LOST ACCELERATION POWER AND EXPERIENCED THE ENGINE FAILURE KNOWN AS "FAIL-SAFE" OR "LIMP-HOME" MODE. AS EVIDENCED BY TOYOTA T-SB-0160-11, WARRANTY POLICY BULLETINS, AND WARRANTY ENHANCEMENT PROGRAMS, TOYOTA IS WELL AWARE OF THIS SERIOUS DESIGN FLAW AND SAFETY ISSUE, YET HAS CHOSEN TO REPAIR OR COMPENSATE ONLY A SELECT FEW. THE PARTS THAT HAD TO BE REPLACED AFTER MY VEHICLE REPEATEDLY WENT INTO 'FAIL-SAFE / LIMP-HOME' MODE CORRESPOND DIRECTLY WITH THE PART NUMBERS REFERENCED IN TOYOTA WARRANTY POLICY BULLETIN POL17-02 WHICH COVERS THIS DEFECT IN OTHER MODELS, BUT NOT IN MY 2012 MODEL. MY OUT-OF-POCKET COST TO REPAIR THIS MANUFACTURER'S DEFECT WAS $3034.87. THIS A KNOWN AIR INJECTION SYSTEM WATER INTRUSION DEFECT AND COMMON SAFETY COMPLAINT AT THE NHTSA AND ON MULTIPLE TOYOTA FORUMS, AFFECTING NUMEROUS 2012 TUNDRA'S WHICH TOYOTA IS REFUSING TO ACKNOWLEDGE AND COMPENSATE FOR. I HAVE WRITTEN SEVERAL LETTERS TO BOTH THE CEO OF TOYOTA AND THE TOYOTA CUSTOMER EXPERIENCE CENTER REQUESTING REIMBURSEMENT OF MY REPAIR COSTS AND HAVE BEEN DENIED TWICE; THE FIRST DENIAL IN WRITING, THE SECOND DENIAL VIA TELEPHONE. I REQUEST THE NHTSA INVESTIGATE THIS SERIOUS SAFETY ISSUE TO PROTECT THE LIVES OF OTHERS DRIVING THESE DANGEROUS VEHICLES. TOYOTA HAS AN ETHICAL AND SAFETY OBLIGATION TO THE CONSUMER TO REMEDY THIS DEFECT AND TO COMPENSATE THOSE OF US WHO HAVE HAD TO BEAR THE FINANCIAL BURDEN OF THEIR FAILURE TO CORRECT THIS WELL-KNOWN ISSUE. *BF

Southeast Toyota is recalling certain model year 2008 and 2010-2013 Toyota Tundra, 2010-2012 Rav4, 2012 Toyota Sequoia, 2010-2011 Toyota Corolla, 2010-2011 Toyota Camry and Camry Hybrid, 2010-2013 Toyota Highlander and Highlander Hybrid, 2010-2013 Toyota FJ Cruiser, 2011 Toyota Land Cruiser, 2010-2013 Toyota Venza, 2010-2011 Toyota 4Runner, 2010-2013 Toyota Tacoma, 2011-2012 Toyota Sienna, 2012 Toyota Prius, 2013 Scion FR-S, 2011 Scion XD, 2011 Scion XB, and 2012 Scion TC vehicles. These vehicles were sold with labels that were outside the allowable one percent of accuracy of actual weight added. Thus, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) Number 110, "Tire Selection and Rims."

Risk: An inaccurate label could lead to owners overloading their vehicles and tires. An overloaded vehicle can result in a tire failure which may result in a vehicle crash, personal injury, or property damage.

Remedy: Southeast Toyota will notify owners and provide a corrected label with instructions concerning its installation. A small group of the affected vehicles will need additonal remedies which are still being developed. The recall began on May 28, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

Air Bags · 13V014000Details +

Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.

Risk: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

Investigations

1 NHTSA investigation on record

Investigations are agency reviews, not findings that a vehicle is defective.

Electrical overstress

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.
