I became the owner of a 2012 Lincoln MKZ Hybrid in 2016. At first there was no issues. Roughly a couple of months later, there was a power steering issue- so the car was driven to Ford with great difficulty where they reset the sensor or something and the power steering was working again. Now a couple of years later, the problem occurred again. The power steering chime came on, the car read “service advancetrac” in yellow and “power steering assist fault” in read, accompanied by the wheel stiffening. I pulled over turned the car off and back on, and the problem went away. It occurred several more times and turning the car off and back on remedied the problem. It would only occur every couple of months, but more recently it started happening every couple of weeks and now- the last ten days it has happened every time I drive. Each of those times, with the exception of the most recent occurrence, turning the car off and letting it sit for a couple of minutes, followed by turning it back on, solved the problem. The most recent time, I was traveling on the highway going 60 mph when the messages appeared and my wheel stiffened. It terrified me as I was moving fast on a Southern California highway where there are hundreds of cars. I was on my way to take a final exam, that I could not miss, so I kept driving. Steering was near impossible at low speeds. I went in to take my final and three hours later, when I turned the car back on, the power steering still was not working. After hours of research and years of dealing with this problem, I have found that there was a recall regarding the PSCM in the 2012 Lincoln MKZ. I am unsure if this problem extends to the hybrid model, and if so whether it was remedied by a past owner, but a detailed vehicle history report indicates that it was not. I have never received any notice as to this recall. I do know that my car was manufactured in the applicable time period (2011), and that it is experiencing exactly what the recall describes.

While driving I noticed that at times my steering wheel would be difficult to turn. At first, the problem seemed small until I was trying to make a left turn on a very busy 4-lane road, and without warning the steering wheel became very difficult to turn. I narrowly avoided being hit and ever since then, the steering has not been the same. I sought help at my nearest Ford dealership and after they inspected the car they determined that there was a problem with the steering assist and possibly the rack and pinion. We then discovered that the very same parts were recalled in 2011 for the same make and model car. I was never notified of any recalls and I asked why I was never contacted. The Ford dealership did not know why. According to them the vehicles that were recalled were vehicles that were made at the same facility as mine. They pointed out that normally my car would have been included in the recall and they did not know why I was excluded. I have attached the documentation they provided me proving that my car was built in a factory that had other cars recalled for the same reason. Currently, they are telling me that they cannot honor this recall because my car is not in the system as one that should be included in this recall. Due to the near misses that I have had I believe that this is a serious safety issue and should not be something that I pay over 2000 dollars to repair. Especially since all the other vehicles that had the same problem were recalled and repaired for free. Please help me figure out how to hold them accountable for not notifying me and refusing to honor the safety recall. NHTSA Campaign Number 15V340000

2EA21002 · 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.

PE14030 · Electric Power Steering Failure
Opened Oct 2, 2014 · Closed Sep 10, 2015
Status: closed (inferred from source dates) · Steering:electric Power Assist System
The Office of Defects Investigation (ODI) opened a preliminary evaluation to investigate complaints of the loss of power steering while driving. The subject vehicles are equipped with a rack mounted Electric Power Assisted Steering (EPAS) unit.Some of the complaints alleged that the steering assist failed and resulted in increased steering efforts that contributed to a loss of control and in some cases a crash.The EPAS system was manufactured by TRW Automotive for Ford and was designated as Generation I.These units were first produced and put into vehicle production in July 2008 beginning with the model year (MY) 2010 Ford Fusion and Mercury Milan.The system is comprised of a mechanical steering rack-and-pinion gear with torque sensor, electric assist motor, motor position sensor and a power steering control module (PSCM). The PSCM is self-monitoring and designed to detect faults within the system and can store diagnostic trouble codes (DTCs) if a problem is detected.There are 29 potential DTCs the system can detect.Many of these allow the system to go into reduced-assist steering mode by using the default vehicle speed signal should the live speed signal be lost, if voltage to EPAS system falls below 10.7 or goes above 17 volts, the temperature at the PSCM goes above 105C (221F), or if high friction is detected.Some DTCs will cause the system to go into manual steering mode (no assist). On July 1, 2015, Ford filed a Defect Information Report (DIR) identifying a safety related defect in TRW GEN I EPAS systems installed in some of the subject vehicles (NHTSA Recall 15V-340, Ford No. 15S18).The DIR indicated that intermittent electrical connections caused by quality issues associated with conformal coat contamination and ribbon cable pin misalignment within the steering gear motor may lead to a loss of the motor position sensor signal, resulting in a sudden loss of power assist while driving.The recall covers approximately 393,623 vehicles built from September 2010 through February 2012:2011-12 Fusion built SEP 2010 - FEB 2012; 2011-12 Lincoln MKZ built SEP 2010 - FEB 2012; 2011 Milan built SEP 2010 - DEC 2010; 2011-13 Taurus built SEP 2010 - FEB 2012; 2011-13 Flex with 3.5L GTDI engine built SEP 2010 - FEB 2012; and 2011-13 MKS, MKT with 3.5L GTDI engine built SEP 2010 - FEB 2012.The repair consists of updating the PSCM software to prevent a loss of steering assist while driving. The revised software will provide audible and visual warnings to the driver. If one or more of the following DTCs are stored, C1B00-62, C200B-2F, C200B-61, C200B-62, C200C-2F, C200D-49, U0300-00, U2011-49, U2011-61, U3000-46, U3000-49, U3000-61, U3000-72, U3000-96, P07AE-09, the dealer will replace the EPAS system at no charge to the owner.ODI's analysis of failure data for this PE identified a total of 2,584 complaints to ODI and Ford and 9,967 Ford warranty claims related to the alleged defect.The recalled vehicles account for 1,634 of the complaints and 7,311 of the warranty claims.ODI's analysis identified 40 complaints alleging crashes that may be related to loss of steering assist while driving, 20 of which involved vehicles included in Ford's recall.The information available for the alleged crashes were not sufficient to assess specific causes of the incidents or to verify EPAS malfunctions in each case.Most of the crashes were low-speed impacts with curbs or roadside objects resulting in wheel or minor body damage.None of the injury claims indicated medical attention was required.In addition, statistical modeling of the failure data by NHTSA's National Center for Statistics and Analysis projected 10-year failur
