While driving downhill and using regenerative braking, my 2013 Acura ILX Hybrid suddenly experienced a hybrid system malfunction. Immediately after the event, the vehicle displayed "Check IMA System" and "Check Charging System" warnings and began exhibiting drivability and electrical-system problems. Following the failure, the vehicle experienced reduced acceleration from a stop, rough engine restarts, loss of auto-stop functionality, charging-system issues, intermittent low-voltage behavior, and eventual no-start/jump-start conditions. The vehicle was inspected and diagnosed by an authorized Acura dealership. Diagnostic testing identified fault codes P0A78 (Motor Power Inverter Internal Circuit Malfunction), P1440 (Motor Power Inverter Module Output Circuit Malfunction), and P1437 (Motor Power Inverter Module Short Circuit). The dealership determined that the Motor Power Inverter had failed and required replacement. The failure affected vehicle propulsion, charging-system operation, and regenerative braking operation. Reduced acceleration and unexpected hybrid-system malfunction while driving created concerns regarding vehicle safety and reliability during normal operation. The Motor Power Inverter was replaced by an Acura dealership and the warning messages, drivability concerns, and related symptoms were resolved. I am submitting this complaint to document a confirmed Motor Power Inverter failure involving a 2013 Acura ILX Hybrid.

MY CAR WAS IN MOTION I WAS DRIVING ON A MAIN STREET AND THEN MY CAR SUDDENLY BROKE DOWN. I HAD NO PRIOR LIGHTS ON. THE VEHICLE BEGAN SHAKING, MY CHECK ENGINE LIGHT BEGAN FLASHING AND THE REST OF THE LIGHTS ON THE DASHBOARD BEGAN FLASHING WITH THE CODE P0202, AND COULD NOT ACCELERATE PAST 3 MPH. I WAS IN THE MIDDLE OF THE STREET AND IT TOOK ME OVER 20 MINUTES TO PULL INTO A GAS STATION THAT WOULD NORMALLY TAKE 5 MINUTES, I DON'T KNOW HOW I EVEN MADE IT TO THE STATION WITHOUT PUSHING THE CAR MYSELF. I HAD TO TOW IT DIRECTLY TO THE ACURA DEALERSHIP. I HAVE OWNED THE CAR LESS THAN 2 YEARS AND HAVE HAD NO PRIOR ISSUES. ACURA NOTIFIED ME IT WAS MY FUEL INJECTOR AND COILS AFTER RUNNING THE DIAGNOSTIC. I HAD TO PAY $1,200 OUT OF POCKET BECAUSE MY WARRANTY EXPIRED. I WAS NOTIFIED THAT THIS WAS A COMPLETE PARTS ISSUE, A RARE OCCURRENCE, THERE WAS NOTHING I COULD HAVE DONE, THIS WAS A MANUFACTURING ISSUE. THEN I RECEIVED A CALL FROM ACURA AFTER THE PARTS WERE REPLACED THAT THEY FRIED OUT THE PCM-THE COMPUTER OF THE CAR. THEY STATED MY CAR WAS NOT DRIVEABLE UNTIL THE PCM WAS REPLACED AND THAT IT DID NOT SHOW IN THE DIAGNOSTIC UNTIL THEY REPLACED THE PARTS. SO NOW, A PARTS FAILURE LED TO AN ELECTRICAL FAILURE. THEY TOLD ME THERE WAS NOTHING LISTED IN THE SERVICE BULLETIN BECAUSE THIS WAS NOT A COMMON ISSUE. I HAD TO PAY AN ADDITIONAL $1,100 NOW TOTALING TO A $2,200 UNPRECEDENTED OUT-OF-POCKET EXPENSE FOR A MANUFACTURER FAILURE. THIS IS TERRIFYING BECAUSE MY CAR WAS WORKING COMPLETELY FINE, DRIVING SMOOTHLY, AND OUT OF NOWHERE WITHOUT ANY INDICATION GAVE OUT ON ME, PLACING MY LIFE IN DANGER. SUSPICIOUSLY ENOUGH, DURING THIS TIMEFRAME, I GET A NOTIFICATION OF A RECALL ON MY VEHICLE FOR A STOP SALE RELATED TO DRIVESHAFT CORROSION WHICH COULD CAUSE MY CAR TO STOP. WHAT IF THIS IS THE ISSUE THAT CAUSED THE OTHER PROBLEMS?

UPON FILLING MY 2013 ACURA ILX, I WOULD GET BACK INTO THE CAR AND THE CABIN SMELLED LIKE I SPILLED GAS IN THE BACK SEAT. THIS HAPPENED ON MULTIPLE OCCASIONS AND THERE WAS A GRAY STREAK FROM THE FENDER ABOUT 3 INCHES WIDE TO IT TAPERING TO ABOUT AN INCH WHEN IT ENDED AT THE BOTTOM OF THE FENDER/BUMPER AREA. I TOOK MY CAR TO THE DEALERSHIP THREE TIMES AND THE CAR WAS NEVER TESTED UNDER THE CONDITIONS OF WHEN I HAD THE ISSUES. THEY DID ALL THE OTHER TESTS EXCEPT THE ONE THAT CAUSED THE PROBLEM, THE VERY BAD GAS FUME SMELLS IN THE CABIN OF THE CAR. IF I LIT A MATCH, THAT CAR WOULD HAVE BLOWN UP, EASILY, THAT'S HOW BAD THE PROBLEM IS WITH THIS CAR. THE 2013 ACURA ILX IS THE SISTER VEHICLE OF HONDA CIVIC. THE HONDA CIVIC WAS RECALLED FOR THE MODEL YEARS 2011 AND 2012 FOR FUEL SYSTEM ISSUES WHICH MIMICKED WHAT I WENT THROUGH WITH THIS 2013 ACURA ILX. I TURNED THAT ACURA IN EARLY AND DID NOT FULFILL THE TERMS OF MY LEASE DUE TO THIS DANGEROUS CAR. I FINALLY GOT FED UP WITH THE DEALERSHIP NOT TESTING MY CAR WHEN THE ISSUE AROSE WITH ME AND THEM TELLING ME THAT THE CAR WAS SAFE. THAT WAS TOTALLY INCORRECT. THIS 2013 ACURA ILX HAD AN INCREDIBLY BAD PROBLEM WITH THE FUEL SYSTEM. I TURNED THE CAR IN EARLY BY HAVING IT TOWED TO THE DEALERSHIP AFTER THE LAST FUEL SMELL IN THE CABIN. I REFUSED TO DRIVE THAT CAR AGAIN. I HAD MY DISABLED WIFE DROP ME OFF TO TRADE THE CAR IN TO THE DEALERSHIP. THE DEALERSHIP WOULD NOT WORK WITH ME NOR WOULD HONDA AMERICA/ACURA. I TRADED IN THE 2013 ACURA ILX TO REPLACE IT WITH A HYUNDAI SONATA, WHICH THE SAME DEALERSHIP GROUP HAD A DEALERSHIP. THE CAR WAS DRIVEN OVER TO THE HYUNDAI DEALERSHIP AND I WAS TOLD THAT I HAD TO WALK 2 BLOCKS DOWN THE 6 LANE ROAD. I AM VERY DISAPPOINTED IN BOTH AMERICAN HONDA AND ACURA AS THEY WILL NOT WORK WITH ME WHATSOEVER. I AM AN UNHAPPY FORMER ACURA ILX OWNER AND WISH THIS PROBLEM BE INVESTIGATED.

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
