SO THEY REPLACE THE ROTORS & DRUMS, AND THE PROBLEM IS RELIEVED FOR A TIME, BUT THE PULSING COMES BACK WITHIN A FEW THOUSAND MILES. I KEEP TELLING THE SERVICE PEOPLE THAT THERE MUST BE A DIFFERENT PROBLEM CAUSING THE BRAKES TO WARP BUT THEY JUST SHRUG IT OFF.

WHEN APPLYING THE POWER BRAKES AT A STOP THE PEDAL AFTER A FEW SECONDS STARTS TO FADE TO THE FLOOR IF RELEASED AND REAPPLIED THEY COME BACK UP TO STOP POSITION AND WILL FADE AGAIN. WHEN BACKING UP AND BRAKES ARE APPLIED AND BACKING SLOWLY TO HOUSE GARAGE THE BRAKE STARTS TO FADE TO THE FLOOR AND HAS TO BE REAPPLIED TO STOP THE TRUCK. YESTERDAY IN A SHOPPING MALL I HAD TO GO AROUND A PARKED CAR WITH ANOTHER CAR HEADED IN MY DIRECTION HAD TO APPLY BRAKES AND SLOWLY MOVE PAST THE PARKED CAR THE PEDAL WENT SO FAR DOWN MY FOOT HIT THE ACCELERATOR AND HAD TO TAKE MY FOOT OFF THE BRAKE PEDAL AND REAPPLY THE BRAKES. HAD TRUCK BACK TO TOYOTA DEALER TWICE AND THEY INSIST THERE IS NO PROBLEM WITH THE TRUCK. IF YOU HAVE EVER DRIVEN AN OLDER CAR WHERE THE MASTER CYLINDER FAILS THAT IS EXACTLY WHAT IT FEELS LIKE, HAVING THAT EXPERIENCE ONCE IN MY DRIVING CAREER OF OVER 60 YEARS/ THE TRUCK TO ME IS NOT A SAFE VEHICLE TO DRIVE AND AM CONCERNED FOR MYSELF AND MY WIFES SAFETY.CALLED CUSTOMER SERVICE 1-800 NUMBER AND WAS TOLD NOTHING THEY CAN DO IF SERVICE DEPT SAID NO PROBLEM WITH THE TRUCK, LOOKING FOR SOME SOLUTION I SEE OTHERS HAVE POSTED THE SAME PROBLEM ON YOUR WEB SITE.

UNPROMPTED ACCELERATION - WHILE DRIVING AT ABOUT 15 MPH IN MODERATE TRAFFIC, I ACCELERATED BRIEFLY AND THEN LET OFF THE GAS PEDAL. AFTER RELEASING THE GAS PEDAL, THE TRUCK CONTINUED TO ACCELERATE AND EVEN DOWNSHIFTED, CAUSING THE TRUCK TO LURCH FORWARD. CONDITIONS - I WAS IN LIGHT TO MODERATE TRAFFIC ON MY COMMUTE TO WORK. THE TRAFFIC WAS STOP-AND-GO. THE CARS AHEAD OF ME ACCELERATED, SO I DID AS WELL. THE CARS AHEAD OF ME QUICKLY DECELERATED, SO I LET OFF THE GAS BUT DID NOT NEED TO BRAKE AS I WAS A SAFE DISTANCE. THE TRUCK CONTINUED TO ACCELERATE WELL AFTER I LET OFF THE GAS AND IT LURCHED FORWARD AND DOWNSHIFTED IN THE PROCESS. THE ENGINE RPM WENT TO ABOUT 3,500. I WAS ABLE TO APPLY THE BRAKE, AND THE ACCELERATION STOPPED AND THE ENGINE WENT BACK TO IDLE. I HAVE EXPERIENCED DECELERATION LAG IN MANY VEHICLES, BUT IN THIS CASE, IT WAS A SURGE, NOT A LAG. IT WAS LONG ENOUGH FOR ME TO THINK OF SHIFTING TO NEUTRAL AND APPLYING THE EMERGENCY BRAKE.

EA19001 · 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.
