I HAVE HAD MANY EPISODES WITH THIS CAR. THE FIRST ONE, I WAS STOPPED AT A STOP SIGN WITH A CAR AHEAD OF, AND BEHIND ME, WHEN I RELEASED THE BRAKE, I TRIED TO MOVE FORWARD, AND IT FELT LIKE I GOT HIT FROM BEHIND, THE CAR LURCHED FORWARD. ANOTHER TIME, MY HUSBAND WAS BACKING OUT OF A PARKING SPOT, AND HE HIT A TELEPHONE IN FRONT OF HIM. HE IS UNCLEAR WHAT HAPPENED. WE HAD DAMAGE TO THE FRONT OF THE CAR WHICH WE HAD TO REPAIR. ANOTHER TIME, I WAS DRIVING IN ECONOMY MODE IN TRAFFIC, WHEN I RELEASED THE BRAKE, AND STARTED TO ACCELERATE, THE CAR DIDN'T MOVE INITIALLY, THEN AFTER A SECOND OR TWO, IT RACED FORWARD WITH MY FOOT OFF THE ACCELERATOR, AND I HIT THE VEHICLE IN FRONT OF ME. ONLY MY CAR WAS DAMAGED. THE DEALER AND ACURA CORPORATE THEN INSPECTED IT AND I WAS TOLD "NOTHING WAS WRONG". MANY TIMES NOW, WHILE DRIVING THE CAR, IT SEEMS THAT THE ENGINE SHIFTS INTO NEUTRAL WHILE I'M DRIVING IT. IF I CONTINUE TO ACCELERATE, IT WILL BE STUCK FOR A FEW SECONDS, THEN PROPELS ME FORWARD WITH A JERK. I WAS TRYING TO DO A LANE CHANGE LAST WEEK, AND THE CAR DIDN'T RESPOND TO MY FOOT ON THE ACCELERATOR, LIKE THE ENGINE WAS "STUCK". I WAS LUCKY THERE WASN'T A CAR BEHIND ME, BECAUSE I CHANGED LANES, THEN ABRUPTLY SLOWED DOWN.I TREATED IT LIKE A HYDROPLANE, I DIDN'T ACCELERATE, AND THE ENGINE RETURNED TO NORMAL FUNCTIONING. LATER THAT DAY, I WAS DRIVING TOWARD A TOLL BOOTH, AND AGAIN, I FELT THE ENGINE SHIFT AND IT WOULDN'T RESPOND TO MY FOOT ON THE ACCELERATOR. THIS CAR IS UNSAFE. I DO NOT FEEL AS IF I CAN DRIVE IT SAFELY. I AM STUCK IN A LEASE FOR TWO MORE YEARS. I WOULD REALLY LIKE THEM TO ACKNOWLEDGE TRANSMISSION PROBLEMS AND GET IT REPAIRED.

AFTER PURCHASING THE VEHICLE NEW, IMMEDIATELY NOTICED HARD AND DELAYED SHIFTING. SHIFTING BETWEEN 1-4 GEARS WAS VERY HARD. AT TIMES TRANSMISSION SEEMED TO BE CONFUSED AND WOULD EITHER PICK THE WRONG GEAR OR WOULD TAKE 2-3 SECONDS TO FINALLY ENGAGE INTO GEAR. ON ONE PARTICULAR OCCURRENCE WHILE DRIVING IN A PARKING LOT AT ABOUT 15 MPH I APPROACHED A STOP SIGN AND LET OFF THE ACCELERATOR. AS SOON AS I LET OFF THE PEDAL THE CAR DROPPED INTO GEAR SO ABRUPTLY THAT IT MADE THE CAR LUNGE FORWARD ABOUT A FOOT OR TWO. ON ANOTHER OCCURRENCE I WAS DRIVING ON A RESIDENTIAL STREET GOING AROUND A TRAFFIC CIRCLE ONCE AGAIN AT APPROX 15MPH I LET OFF THE ACCELERATOR FOR A MOMENT AS I WENT AROUND THE CIRCLE. JUST AS I WAS EXITING THE CIRCLE I DEPRESSED THE ACCELERATOR TO MOVE QUICKLY AWAY SINCE I SAW ANOTHER VEHICLE ENTERING THE CIRCLE. AT THIS POINT THE RPM'S WENT ABOVE 3500 AND THE CAR DID NOT SHIFT AND DID NOT MOVE. IT APPEARED THAT THE CAR WAS IN NEUTRAL. IT TOOK ABOUT 1-2 SECONDS BEFORE THE TRANSMISSION WAS ABLE TO "FIND" A GEAR AT WHICH POINT IT LUNGED FORWARD ABRUPTLY. BOTH SITUATION I DID NOT HAVE CONTROL OF THE VEHICLE BECAUSE OF THE TRANSMISSION. BOTH SITUATIONS I WAS UNABLE TO CONTROL THE VEHICLE IN A SAFE MANOR. I HAVE ALSO AT TIMES NEEDED TO ACCELERATE QUICKLY INTO A MERGE LANE AND WHEN "STOMPING" ON THE GAS NOTHING WOULD HAPPEN FOR 2-3 SECONDS.

WHILE THE VEHICLE WAS UNATTENDED (NO DRIVER PRESENT) AND TRANSMISSION WAS ENGAGED IN PARK; I WAS PRESENT WHEN USING THE REMOTE STARTED. UPON STARTING (VEHICLE WAS STARTED), IT ROLLED UP A SLIGHT INCLINED DRIVEWAY ROUGHLY 3-6 INCHES , UNDER POWER; THEN ROLLED BACK SHE SAME DISTANCE. THEN A DISTINCT CLICK WAS HEARD. THE CAR CONTINUED RUNNING IN IDLE AS NORMAL WITH THE REMOTE START. ACURA HAS REPORTED TRANSMISSION ISSUES WITH THE POTENTIAL FOR THE CAR TO DISENGAGE FROM PARK (MODEL SH-AWD) AND ROLL AWAY. THIS CAR WAS RECALLED FOR "ROLL" WHILE PARKED AND NOT RUNNING, , BUT PASSED AND INSPECTION BY THE DEALER. UNLIKE THE PREVIOUS RECALL THIS ISSUE ENTAILED A "SHIFT INTO FORWARD", FROM PARK, UNDER POWER WHILE UNATTENDED. I NOTIFIED ACURA CUSTOMER SERVICE TO REPORT IT, WAS TOLD TO BRING IT IN, BUT IF THE ISSUE CANNOT BE RECREATED THEN IT CANNOT BE REPAIRED. THIS EVENT COUPLED WITH THE PREVIOUS RECALL, HAS ME CONCERNED THAT ACURA IS NOT ADDRESSING SERIOUS SAFETY CONCERNS OF ITS CONSUMERS.

I NOTICED THE FIRST TIME I ACCELERATED QUICKLY TO MERGE ONTO THE INTERSTATE THAT THE ENGINE HESITATED AT LEAST A SECOND TO SECOND AND HALF BEFORE ACCELERATING. AFTER THAT, I STARTED NOTICING THE SAME HESITATION WHENEVER I PUNCHED THE GAS PEDAL TO EITHER MERGE INTO TRAFFIC OR PASS SOMEONE. I HAVE READ ON THE INTERNET WHERE OTHER OWNERS OF THIS VEHICLE HAVE THE SAME PROBLEM. I JUST TOOK THE CAR IN FOR IT'S FIRST OIL CHANGE AND I COMPLAINED ABOUT THIS ISSUE. THE DEALER RAN SEVERAL COMPUTER SOFTWARE UPDATES ON MY CAR AND SAID THAT IT WAS UP TO DATE AND THAT BASICALLY THAT IS THE WAY THE CAR IS. I FEEL THIS IS A BIG SAFETY ISSUE. I HAVE ADAPTED TO DRIVING THE CAR WITH THIS HESITATION, BUT I'M NOT HAPPY WITH IT. I THINK ACURA NEEDS TO ADDRESS THIS PROBLEM BEFORE SOMEONE GETS HURT.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy.

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.
