FOR THESE LAST SEVERAL MONTHS, NEAR OR AROUND DECEMBER OF 2025 MY 2016 LINCOLN MKX HAS BEEN SHORTING OUT OR HAVING GLITCHES IN THE CENTER CABIN. THE CROSS TRAFFIC SYSTEM AND BLINDSPOT SYTEM FAULT HAVE TURNED ON AND OFF SIMULTANEOUSLY CREATING A SHORT IN THE CABIN RESULTING IN THE ac OR hEAT TURNING OFF AND ON. THIS ALSO CREATES A SHORT WHERE THE THE WINDOWS WILL NOT ROLL DOWN, THE GLOVE BOX WILL NOT OPEN OR THE TRUNK, THE DOORS CANT OPEN FROM THE OUTSIDE. AND MOST SERIOUS, MY KEY FOB WILL NOT OPEN THE VEHICLE. THE lINCOLN DEALERSHIP IS AWARE OF THE PROBLEM BUT HAS REFUSED TO ADDRESS THE PROBLEM BECAUSE THEY CLAIM THEY CANNOT REPLICATE THE ISSUE. THE DEALERSHIP HAS WITNESSED THE PROBLEM, YET THEIR TECH IS NEVER AVAILABLE. THE DEALERSHIP IS AWARE OF THE ISSUE, AND HAS SEEN VIDEOS OF THE PROBLEM BUT REFUSES TO ADDRESS. ORIGINALLY CAR MAX REFERRED THE CAR TO LINCOLN BECAUSE CARMAX CLAIMED THEY DO NOT HAVE THE TECHNOLOGY TO ADDRESS THE LINCOLN'S ISSUES. LINCOLN CLAIMS THEY CANNOT REPLICATE AND THAT I SHOULD WAIT FOR THE CAR TO BREAK DOWN.

My car is currently under two recall notices however only one of the issues has been communicated to me of resolution. One being emissions control 25E02 and second being Recall 25S87 REAR BRAKE FLEXIBLE HOSE LEAK. Recall 1- emissions has been a problem for about 2 years now. Emissions are connected to my engine thus having my check engine light come on. My car failed an emissions test but was only 4 years old and the catalytic converters are not broken, have hole, anything leading to failed test, car repair fees and non-registered vehicle. The second recall is not being fixed, and I have had to replace my brake house, line and rear right brake twice this year. Lastly, I have collision warning however it does not work properly if at all. I was in a minor fender bender when I went to push on brakes the sound to warn me of a collision did not go off until after the crash! I am unsure of the process but if connected to my braking system it failed and if it is a preventative measure it sucks.

I have spent numerous (more than 3 major problems) For example, a lot of dollars fixing water pump. The design is messed up where they place the water pump. Thousands in labor. The electric driver control malfunction and tire pressure is always lit. This occurred on drive home from brake recall fix. The engine stalls and also leaks. The seat moves sometimes without me wanting it to. The emergency brake slams on and stops and locks the car when in drive or reverse. Lincoln has been zero help and gave false promises.

The major problem occurred right after purchase as check engine light came on. The dealership was no help and refused to take vehicle back. The vehicle is nice looking but the mechanical is a lemon. I purchased this in 2020 and paid $24000. It’s a 2016 Lincoln mkx. I repaired problems and due to covid and my lifestyle I rarely traveled. I have more medical issues and require more frequent doctor visits. I never went back to Brennegen after not standing by this vehicle shortly after purchase. I just tried to focus on the positive and started doing business elsewhere. I maintained proper service. Brennegen did not disclose active recall before purchase. Since purchase I have repaired two problems brakes, and fire risk to engine. At this months regular oils change my current mechanic Dahl ford said the water pump was leaking. The estimated repair is $5000. I paid just to have it diagnosed yesterday as I have not $5000. I followed their advice and parked this. My vehicle is currently not drivable. I investigated and discovered Lincoln Ford has several class action lawsuits filed against them. Many consumers have the water pump problem and unfortunately Lincoln was well informed of this since 2007 and purposely have not fixed the issue. Yet currently many consumers like me are in danger of eminent engine failure and catastrophic failure of Lincoln vehicles. The cost is far more expensive for many and consumers should not be victims of lemons and fraud. Lincoln knew and currently knows of problem. They denied to buy back my vehicle or repair it. The case was just filed yesterday and Lincoln denied it in less than 12 hours. Without any Investigation Or explanation they just told the other department rep to call me back and deny my complaint. I am not the only o e and lawyers are now involved in class action . Please help me start o e I. My area or get Lincoln to stand behind their advertisement as this is a blatant lie. The water pump is too expensive to fix. Please help!

The power steering went completely out while I was driving down the highway. I believe the problem is related to the power steering control module and the electric assist rack and pinion steering. It was the most dangerous situation I ever encountered. I narrowly missed causing an accident. There are several makes of Ford/Lincoln vehicles that have this problem dating back to 2011. The service advance trac displayed, steering assist fault service required displayed, pre collision assist not available displayed, hill assist not available displayed and a few others. They first appeared on Dec. 4th and next appeared around the 28th. The MKX is currently at Joe Machens Lincoln in Columbia, MO being inspected by the dealership and endurance, my warranty company.

In early September the vehicle was completely without electrical power. My husband was able to jump start the car. We bought a new battery from AutoZone and it was installed by their technician. September 22, 2022 the same issue occurred and the car had to be jump started. I took the vehicle to the dealership who was able to find no cause of the failure. There were no warning lamps, messages or other symptoms (no difficulty starting etc.) Based on other accounts this appears to be associated with NHTSA Campaign # 19V809000 - Electrical System. The dealership did not charge me for anything related to this failure as they could not recreate it.

While driving, there is an electrical issue that is causing warning alarms to go off for hill-descend control, advance-trac traction control, etc. During this time, there is also a complete loss of power steering and making the vehicle almost impossible to turn. The first incident happened on November 26, 2021 around 7pm were I was able to stop prior to hitting a building. I shut the vehicle off and back on again and the power steering was now working. I was unable to get Lincoln to tow the vehicle because it was "too far" from the roadside tow drivers service area. On the same day, I drove it the rest of the way home but upon exciting the highway around 7:30pm, the power steering again went out and I was able to stop the vehicle prior to going into the ditch next to the road. I had it towed to a Lincoln dealer in Wixom, Michigan but over the weekend could not locate the vehicle and at that point I was talking to an Advisor with Lincoln. They told her it would be at least 5 weeks before they could even look at the vehicle so per her recommendation, it was towed to Lafontaine Lincoln in Flushing, Michigan. It was in the shop until Wednesday, December 15th. I was informed they changed out the steering rack and pinion but was given no paperwork because they told me it was all covered under warranty. On December 21, 2021 while driving on Linden Road in Fenton, Michigan, it did the same thing with my wife driving and resulted in a compete loss of power steering and she went into the oncoming lane around a bend before she was able to get the vehicle stopped. Luckily there was no oncoming traffic. I will be having it towed again to the dealership. Luckily for me, these incidents have only resulted in near-miss situations but this is a major issue and will result in serious accidents if it hasn't already.

1EA21002 · 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.

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.
