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 has faulty code P0AE1 (Bypass Contractor Malfunction) that causes the 12v battery and hybrid battery failure. It also causes the brake less effective without hybrid assisting, and loss acceleration that are extremely dangerous while driving on road. This is well known issue for 2013 Acura ILX hybrid that triggers recall in Service Bulletin 20-021. My car has been inspected by Honda/Acura dealer, but the VIN is not in the recall campaign, so Acura denied the service warranty for this. I believe there are more vehicles that are effected that is not in the recall campaign VIN.

Contacted manufacturer and been informed that no recall for my car vin is bot associated to recall above (20-021). Did check report from carfax and only repair on my car was some on battery in 2019 (attaching too). My car has exact same codes and diagnose from Nalley Acura service points to IMA inverter (p1440 & p1505) and needs to be replaced. As can be seen from my statements, entire diagnose points to exact same symptoms and car is also under same model and year but manufacturer didn’t include vin into recall to fix the issue. Please help me with resolving this issue and to get my car repaired under service bulletin as supposed to be from beginning. Attaching all conversations with manufacturer and also diagnose and dealer service advisor details.

Over the past few weeks the vehicle warning lamp states "Check Power Steering System." A customer service representative from Acura Dealer witnessed the problem. Then somehow it corrects itself for a while and steering is back to normal. My most recent diagnostic by an independent service center did not indicate a problem. However, 2 days later the problem reoccurred which caused the wheel to shake and stiffen while driving. The most difficulty experience is turning the wheel to park.

Issue had not been persistent, on Sunday, May the 12th, 2024, while driving home, I was on a slight downward slope coming to a halt at a red light, when the car jolted slightly and the warning lights came. The auto-shutoff feature on the vehicle stopped working immediately. I was able to drive the car home, but after parking - the vehicle wouldn’t start again. Electronic screen on the radio came on and I could see error codes P1437 & P15A5. Also warnings on the dash to check IMA system, check charging system, check battery, check breaking system. Power steering locked up due to the voltage shortage. What is the reason/explanation provided by the dealer, as to what caused this issue? DTC'S P0A78 - MPI INTERNAL CIRCUIT MALFUNCTION, P1440 - MPI OUT CIRCUIT MALFUNCTION. MPI FAILING INTERNALLY, CAUSING 12V BATTERY TO LOSE CHARGE. Previously parts involved were recalled in Dec 2020, since American Honda didn’t not include my VIN they have refused to be of any assistance - monopolizing on being the only available source to change the parts. Had I received the recall, I would have had it addressed prior to the part going out. I’m 6330 miles over what they would have covered because I had no idea this was an issue until I found the safety bulletin which exactly described the recall and what happened to be my experience. Same issues, but I’m being told I couldn’t be included. They are charging me over $1400 for the part alone and then service which includes a complete removal of my back seats. I JUST spent nearly $4000 in Feb 2023 on the AC because the car wouldn’t start, who is to say this wasn’t undetected issue at the time?!

Hi - My driver's side door keeps unlocking and registering as if I am opening it as I am driving. I've attempted to have this fixed (stopped unlocking for about a year) but it has started back up within the last month. It's now come to my attention that upon searching for safety recalls on my car, that there was a recall back in 2012 (12V338000) on my car for what sounds exactly like the issue I've been having. I have an appointment to get Driveshaft Corrosion (20V-770) recall fixed on 11/6, but they do not have the other safety recall associated with my VIN number. Therefore, they are refusing to look at it without payment. I would hate to have to pay for a temporary fix again and I am extremely concerned that I cannot drive my vehicle without it unlocking and am really hoping this reaches the right audience. I am looking for assistance in having this resolved. Thank you!

On July 20th, 2023, while driving home from work, my vehicle without warning made a sudden jerk and all the warning light s came on the dash board. The car had reduced power and acceleration and an automated voice from the dash board warned to pull over the car. I pulled over into a garage who performed a diagnostic. They stated the error codes indicated MPI failure (IMA power moter invertor). They also stated there was a Service Bulletin 20-021 for tis issue with this car (same year /model). When a VIN check was performed, the vehicle did not come up on this TSB. I had the car towed to an acura dealer and they ran a diagnostic. They confirmed error codes P1440,P15A5,P0AE1,P0DA8 - all codes listed in the service builletin 20-021 for this vehicle year, make and model. I have no doubt, as the data indicates, this failure/incident was caused by the same issues which are covered under TSB 20-021 and this VIN should be included.

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?

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.

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.
