DRIVING ON INTERSTATE FOR 8 MIN AT 70 MPH ON A 70 DEGREE MORNING WHEN I LOST POWER TO THE ENGINE. LUCKILY, I WAS ABLE TO PULL OVER TO THE SHOULDER. MY CERTIFIED MECHANIC DIAGNOSED THE ENGINE LOST ALL COMPRESSION. THE CAR HAS 98,000 MI. I CALLED ACURA CLIENT SERVICES AND THEY STATED IT HAD TO BE DIAGNOSED BY ACURA DEALER. THE DEALER STATED IT WAS A BLOWN ENGINE AND THEY HAVE NO IDEA HOW IT HAPPENED. I CALLED ACURA AGAIN AND THEY STATED THERE WAS NOTHING THEY COULD DO. I STATED SOMETHING UNUSUAL HAS HAPPENED AND IT SHOULD BE RESEARCHED TO UNDERSTAND WHY. ENGINES SHOULDN'T JUST FAIL. ACURA STATED THE VEHICLE IS OUT OF WARRANTY AND THE CUSTOMER WOULD HAVE TO PAY FOR THE DIAGNOSIS BEFORE THEY WOULD REVIEW THE CLAIM. I PAID THE DEALER TO TEST. THE DEALER FILLED THE SYSTEM WITH FLUIDS AND SET THE VEHICLE OUTSIDE. HE CHECKED FOR LEAKS EVERY FEW HOURS. I TOLD HIM IT WAS A SLOW LEAK AND HE HAD TO MONITOR IT CLOSELY. THE DEALER STATED HE COULDN'T FIND ANY ISSUE. I CALLED ACURA AND TOLD THEM THE TEST WAS NOT CONDUCTED PROPERLY. ACURA STATED THE DEALER CAN'T FIND THE ISSUE AND NO MORE INVESTIGATION CAN BE DONE. I ASKED ACURA WHY THEY ARE NOT HAVING THEIR FIELD TEAM REVIEW THIS INCIDENT. ACURA STATES IT'S A CUSTOMER ISSUE NOT AN ACURA ISSUE. WITHOUT CONDUCTING THE PROPER TESTING & DIAGNOSIS THAT CONCLUSION CANNOT BE MADE. ACURA REFUSES TO AUTHORIZE THE DEALER TO INVESTIGATE THE DEFECT PROPERLY. ACURA REFUSES TO HAVE THEIR FIELD TECHNICIANS, WARRANTY GROUP, AND SUPPLIER REVIEW THE DEFECT, ASKS THE CUSTOMER TO PAY TO DIAGNOSE THE PROBLEM. ACURA'S POLICY TO NOT REVIEW MAJOR FIELD ISSUES WITH THEIR VEHICLES OUTSIDE OF WARRANTY IS A DANGEROUS POSITION ESPECIALLY WHEN IT IS A MAJOR SAFETY ISSUE WITH A BLOWN ENGINE. ACURA'S CORPORATE STRATEGY TO SUPPRESS AN INVESTIGATION UNTIL A MAJOR INCIDENT HAPPENS CREATES A POTENTIAL RISKY PRODUCT LIABILITY WITH ALL THEIR CUSTOMERS.

ON 7/20/2017, I WAS DRIVING ON I-680 S TOWARDS FREMONT CA. I WAS DRIVING ROUGHLY 70 MPH. WHEN I WAS ABOUT TO PASS A CAR, ALL OF A SUDDEN, THE ENGINE LOST POWER. I HIT THE GAS PADDLE ALL THE WAY DOWN, AND IT DIDN'T WORK. AS I FELT A SIGNIFICANT LOSS OF POWER, I PULL OVER TO THE SIDE AND STOPPED THE VEHICLE. THE ENGINE SHUT DOWN IMMEDIATELY WHEN I CAME TO A COMPLETE STOP. I TRIED TO RESTART MY CAR, BUT IT DOES NOT WORK, AND THE ENGINE CHECK LIGHT POPPED UP. I HAD MY INSURANCE TOWED MY CAR TO OAKLAND ACURA, AS I DID AN OIL CHANGE THERE ON 7/19/2017. AFTER AN INSPECTION, OAKLAND ACURA INDICATED THAT THE INTAKE AND EXHAUST VALVE DOES NOT OPEN AND CLOSE NORMALLY. A VALUE ADJUSTMENT WILL SOLVE THE PROBLEM. I FELT THAT IT'S PRETTY IMPOSSIBLE FOR ALL THE VALVES TO BE MALFUNCTION ALL AT ONCE. THUS, I ASKED THE TECHNICIAN ARE ALL THE VALVES MALFUNCTIONING, THE TECHNICIAN SAID SHOULD BE. I THEN ASKED WHETHER SUCH A PROBLEM IS CAUSED BY AN IMPROPER OIL CHANGE SINCE THEY DID MY OIL CHANGE THE DAY BEFORE, AND I ONLY DROVE 25 MILES AFTER THE OLI CHANGE. THE TECHNICIAN SAID, "I DON'T THINK SO". I FURTHER ASKED WHETHER IT'S AN ENGINE DESIGN PROBLEM THAT IS SUBJECT TO A RECALL, THE TECHNICIAN COMMENTED THAT THESE ENGINES LAST FOREVER. THUS, THEY DID A VALVE ADJUSTMENT FOR ME, EVEN THOUGH I DON'T KNOW WHAT THEY REALLY DID. I GOT CHARGED FOR $499 FOR THIS VALVE ADJUSTMENT. I ALSO NOTICED THAT WHEN I STARTED MY ENGINE (ESPECIALLY IN COLD WEATHER), MY CAR HAS A BUBBLING NOISE. I NOTICED THAT ON MANY ACURA FORUM, MANY ACURA TL OWNERS HAVE THE SAME PROBLEM. I ASKED OAKLAND ACURA TO LOOK INTO THIS. THE CONCLUSION THEY GAVE ME WAS INCONCLUSIVE. I WANT TO REPORT THIS ISSUE BECAUSE IT WAS REALLY DANGEROUS THAT AN ENGINE LOST POWER COMPLETELY ON A HIGH WAY. I AM NOT SURE IF IT'S AN ENGINE DESIGN PROBLEM OR NOT, SO I THOUGHT I SHOULD REPORT THIS.

I PAID TO HAVE CAMSHAFT REPLACED BUT HAVE BEEN IN AUTOMOTIVE FIELD 50 YEARS SO I KNOW UNLESS THERE IS A PROBLEM THIS IS NOT A NORMAL WEAR ITEM.. I ASKED FOR THE OLD PARTS AFTER THE REPAIR. INSPECTION OF THE OLD CAMSHAFT SHOWED ONLY ONE LOB HAD UNUSUAL WEAR WHICH AGAIN IS UNUSUAL. I DID A ROCKWELL HARDNESS TEST ON THE SUSPECT LOBE AND THE VERY NEXT LOBE AND FOUND A SIGNIFICANT DIFFERENCE IN HARDNESS. THE NON WORN LOB WAS 47.9C AND THE FAILED LOB MEASURED 42C. I LOOKED ON LINE AND NOTICED MANY OTHER ACURA/HONDA OWNERS HAD POSTED MESSAGES ABOUT THE SAME FAILURES. I CONTACTED HONDA CUSTOMER SERVICE AND GAVE THEM THIS SAME INFORMATION. ABOUT THREE WEEKS LATER I RECEIVED A CALL LETTING ME KNOW THEY DIDN'T,T FEEL RESPONSIBLE BECAUSE THE CAR IS OUT OF WARRANTY AND I USED A HONDA DEALER FOR THE REPAIR RATHER THAN AN ACURA DEALER.

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.
