Water leaked through the third brake light assembly into the cab roof, soaking the ceiling, seats, and carpet. This caused extensive mold growth and electrical corrosion near the control modules. The affected systems include the third brake light seal, cab roof, interior materials, and ECM (documentation attached). The truck remains at the dealer and is available for inspection upon request. The entire interior is contaminated with mold, creating a serious health hazard, and the vehicle cannot be safely driven or occupied. The leak also damaged electrical components, posing a risk of malfunction or short-circuit while operating the vehicle, and it is currently undrivable due to this damage. The problem was confirmed by Toyota of Clermont, which inspected the truck, documented the damage, and provided a written estimate exceeding $8,000 for repairs (copy attached). The vehicle was at the dealership while the manufacturer’s Limited Service Campaign 21TD03—issued to address this same defect—was still active, but the required inspection and seal repair were not performed. The failure of Toyota of Clermont to perform the mandated remedy under Campaign 21TD03 while the vehicle was in its possession resulted in a serious safety hazard. The entire interior of the cab—including the seats, ceiling, and carpet—is covered in mold, and the vehicle is undrivable due to water intrusion and electrical damage. There were no warning lamps or error messages before the failure, only a strong musty smell inside the cab shortly before the leak became visible. Toyota Motor North America was notified but declined responsibility. This case represents a potential noncompliance with federal defect-remedy obligations under the National Traffic and Motor Vehicle Safety Act (49 U.S.C. § 30120) and should be investigated as such.

My check engine light came on when I was traveling in Oregon. I didn't notice any major changes in my vehicle's performance. Drove it all the way back to Colorado without issues. It went off and came back on several times. I replaced the cabin air filter, engine air filter and put fuel injector cleaner in the vehicle. Finally I took it in to the Toyota dealership to get an oil change and then the check engine light came back on. I paid for them to do a diagnostic test and they stated they were almost certain it was the 2nd fuel injector running rich. Brought it back a week later for the repair. Fyi...I was still getting 20 mpg in fuel and I wasn't noticing anything major in performance. They replaced the fuel injector and then the check engine light came back on with a different code. They are now running "another" more expensive diagnostic test and I still don't have my truck. They are saying it could be the 2nd cylinder or the engine and claiming it has 150,000 miles so I should expect these issues (and conveniently my warranty has run out).

I currently own a 2019 Tacoma with around 70,000 miles on it. I keep up with all the Toyota recommended maintenance services to make sure my vehicle is well taken care of. So, while driving the vehicle on the interstate it drastically slowed down on its own and I could not get the gas pedal to engage almost causing a rear end collision. This also happened on two other occasions at lower speeds. My display stated I was having issues with ABS, Collision, and that I was pressing the gas pedal and break at the same time. My vehicle has been at the dealership for 4 days now with no resolve or any answers to why the vehicle is slowing down on its own. I feel the vehicle is a health/safety issue and I will not drive it until the issue is resolved. The computer was also flashed by Toyota a year earlier as I was experiencing a lag in engine engagement and high rpm's when the vehicle shifted from first to second gear. Something the tech noted he experienced driving it. It's also an issue I've had since purchasing the vehicle. I had to bring the vehicle back a month later as it started doing the same thing but was told they could not find any issues. I have found many other forums and spoke with other Tacoma owners who have had similar issues. I feel Toyota is definitely aware of the issues but not addressing them! I hope to get some answers soon!

I was driving my truck a 2019 TRD off road Tacoma from San Diego to LA I was on the 605 freeway in the fast lane when I noticed smoke smell and then I noticed fire flames by the air conditioner and the phone charging plate I proceed to Exit the freeway thankfully I did not get in a car accident with any other vehicles however I was unable to stop and put out the fire. It's very upsetting because at no fault of my own I am now lob obligated to find another vehicle and I am not in the financial or credit position that I was when I bought my truck that is now a total loss by my insurance it covers my loan but not much after that so the fact that I've heard that this has been an issue for a few other Tacoma's And it's not even listed yet there's a problem the fact that this is not within my control as to what happened and there's nothing but oh well good luck getting another car Something needs to change.

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.
