All the safety error lights come up on dash (ABS, steering control, tire pressure, stability control) all aluminate. Initially they would only come on when vehicle sat while running for more than a few min and once parked overnight they would not come back on. Now they are on 100% of the time and never go off. There a a ton of videos out there with a faulty ANS module. Honda is selling them for like $1400 part + labor. An entire industry has started to repair them and video showing the fault in wiring showing bad soldering joints where very thin wire is attached. My car has 95,500 miles on it.

the fuel pump on my 2013 honda accord went out. Ive taken the vehicle to the honda dealer multiple times to get it diagnosed and they keep telling me its the high pressure fuel pump and once replaced my car will run smoothly.NOT the case ive replaced it more than 6 times, my car still stalls and turns off at random so im unable to drive the vehicle. it starts and drives but you have to look at the rpms while driving, if i go over 2000 rpms itll stall. when the issue first started i was at a redlight when the vehicle stalled, thankfully no one was around me since it was late but had there been traffic my car would have been hit. i have 2 children and I cant and will not put them in that car knowing it has a problem no one is willing to take a deep dive into. Due to this issue multiple lights on the dash are on and wont go off until the problem is fixed.

There is something wrong with the electric power steering. Every time I drive my steering wheel pulls to the left so if I let go of the steering wheel the steering wheel will pull to the left and could potentially cause a car crash and while driving and difficulty steering (either steering feeling too firm or too loose). This is happening without the electric power steering warning light being illuminated. I do not feel safe.

5EA21002 · 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.

EA21001 · Loss Of Direction Control
Opened May 6, 2021 · Closed Aug 25, 2023
Status: closed (inferred from source dates) · Steering
On May 6, 2021, the Office of Defects Investigation (ODI) opened Engineering Analysis (EA21-001) to assess a sudden loss of steering control, in Model Year (MY) 2013-2015 Honda Accord vehicles. Consumers alleged while driving the steering wheel would pull to the left or the right independently. Steering pull may pose a risk of loss of directional control. Honda stated that they believed the inadvertent steering input was caused by a loose magnet located within the electronic power steering (EPS) system. Due to poor formulation of the adhesive, this magnet can become loose and move up to 2 degrees around the steering column. When the magnet moves, the torque sensor generates a signal that results in unwanted steering in either direction. Honda stated the steering force required to maintain directional control with a loose magnet is a maximum of 3-pound feet. The maximum force of the unwanted steering input can be overcome by the driver and is similar to driving on grooved pavement.The Vehicle Research Test Center (VRTC) sent over 4,000 questionnaires to 2013-2015 Honda Accord vehicle owners. Of the 637 responses, 58 consumers experienced unwanted steering. Consumers experiencing unwanted steering did not report difficulties maintaining directional control. There were no crashes or injuries reported to VRTC. Testing done by VRTC was not able to reproduce the allegations. Analysis of all relevant data indicates that the subject condition has a relatively low failure rate. The poor adhesive formulation was addressed by the supplier with three (3) counter measures in the manufacturing process.There has been a declining trend in consumer complaints to NHTSA which indicates possible exhaustion of parts prone to failure. In view of the low rate, declining complaint trend, the nature of failure, and resolution of the adhesive formulation, this Engineering Analysis is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI complaints cited above can be viewed at www.NHTSA.gov under the following ODI identification numbers: 11538714, 11528538, 11528008, 11522953, 11496557, 11495837, 11494328, 11478680, 11477167, 11476758, 11476263, 11471198, 11470001, 11467026, 11466561, 11466016, 11465626, 11464143, 11463558, 11462759, 11461500, 11460777, 11460191, 11455540, 11454334, 11452198, 11448114, 11447666, 11444888, 11444823, 11444172, 11443324, 11443243, 11443105, 11441374, 11439520, 11438345, 11437261, 11436824, 11436350, 11435994, 11435079, 11434969, 11434545, 11434442, 11434381, 11433824, 11433745, 11433555, 11433368, 11433176, 11431206, 11430465, 11430253, 11430009, 11429253, 11428301, 11427449, 11426841, 11426340, 11425928, 11425261, 11425230, 11423611, 11423245, 11422445, 11422395, 11422351, 11422220, 11422138, 11422069, 11421683, 11421589, 11421540, 11420573, 11419338, 11419270, 11418147, 11418143, 11417768, 11417742, 11417570, 11417437, 11416804, 11416699, 11416401, 11416378, 11416375, 11416155, 11416117, 11416084, 11416051, 11416032, 11416028, 11416024, 11416000, 11415933, 11415915, 11414105, 11406220, 11398736 ,11387075, 11387049, 11375580, 11364698, 11361125, 11351660, 11349961, 11327909, 11327170, 11301957, 11289067, 11282525, 11277659, 11258017, 11256914, 11218752, 11208077, 11196050, 11194358, 11189901, 11165075, 11163481, 11154891

Status: closed (inferred from source dates) · Steering
The Office of Defects Investigation (ODI) received a petition dated October 19, 2020 requesting an investigation of an alleged defect in the steering system in Model Year (MY) 2013 Honda Accord vehicles. The petitioner alleges that MY2013 Honda accord vehicles are experiencing a sudden loss of steering control as the vehicle veers from its intended path of travel. The petitioner further alleges that this deviation from the intended path of travel occurs without warning or driver input while operating the vehicle under normal driving conditions. The petition itself can be reviewed at NHTSA.gov under ODI Number 11349961.On November 23, 2020, ODI opened a Defect Petition (DP20-005) to evaluate whether to grant or deny the petition. ODI sent two Information Request (IR) letters to Honda requesting information on steering anomalies in MY2013 Honda Accord vehicles and later MY2014-2015 Honda Accord vehicles.ODI performed extensive analysis on the information obtained from Honda as well as information in NHTSA's database.Based on ODI's review of the applicable materials, including responses to the IR letters sent to Honda, Vehicle Owner Questionnaires (VOQ) and Early Warning Reporting data, NHTSA has decided to grant the petition. ODI has opened an Engineering Analysis (EA21-001) to assess the scope, frequency and potential safety related consequences of the alleged defect, a sudden loss of steering control.The ODI complaints cited above can be viewed at www.NHTSA.gov under the following ODI identification numbers:11414105, 11406220, 11398736, 11387462 ,11387075, 11387049, 11375580, 11364698 ,11361125, 11351660, 11349961, 11327909, 11327170, 11324181, 11306112, 11301957, 11289067, 11282525, 11278511, 11277659, 11258017, 11256914, 11218752, 11208077, 11196050, 11194358, 11189901, 11165075, 11163481, 11156378, 11154891, 11131050
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.
PE14033 · Electric Power Steering Failure
Opened Nov 4, 2014 · Closed Oct 6, 2015
Status: closed (inferred from source dates) · Steering:electric Power Assist System
The Office of Defects Investigation (ODI) opened PE14-033 to investigate 24 complaints alleging loss of power steering while driving in model year (MY) 2013 Honda Accord vehicles equipped with electric power steering (EPS).Analysis of service data for the original 24 complaints and 33 additional complaints received after PE14-033 was opened found that 85 percent of the vehicles with diagnostic trouble codes available to identify the faulty component had a code indicating torque sensor failure (DTC 53).In its response to ODI's information request letter for PE14-033, Honda identified two manufacturing process conditions that may have affected the quality of some early production torque sensors.Analysis of warranty returns and manufacturing processes determined that a relatively small number of torque sensors were potentially affected by the conditions, which were corrected by the supplier (Bourns) relatively early in production.Analysis of warranty data indicates that both conditions were early-life failure concerns and most of the affected sensors have already failed, resulting in a cumulative failure rate of less than 0.2 percent.Of the 20 VOQ's that appear to be related to torque sensor failure, 6 reported failure dates in 2013, 12 in 2014, and just 2 to date in 2015.ODI's analysis identified 2 minor crashes with no injuries that may have been related to torque sensor failure in the subject vehicles.This investigation is closed because the low failure rate and a declining trend indicate that failures are rare.The closing of this preliminary evaluation does not constitute a determination that no defect exists or that power steering failures do not present an unreasonable risk to safety. The VOQ's referenced in this resume are:10515618, 10515696, 10537336, 10542360, 10545177, 10563724, 10588425, 10595068, 10605909, 10627926, 10629629, 10630852, 10644762, 10654768, 10661240, 10664234, 10667364, 10672452, 10676256, and 10695191
