The internal water pump failed, dumping a half gallon of antifreeze into the engine oil. This caused the engine to suddenly stall and lose all power while driving in the middle of active traffic, creating a severe crash hazard .

Engine complaints
32 reportsI have an oil consumption issue. There is a technical service Bulletin# 19-2243 indicating this is a known problem with my SUV. My Lincoln Protection Plan and Lincoln Corporate refuse to assist in replacing the engine.
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.

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.
Engine shutoff suddenly while driving, mainly on freeways & roads that have long downhills, while foot is off the gas pedal. But it happens on flat roads also.

Engine shutoff suddenly while driving, mainly on freeways & roads that have long downhills, while foot is off the gas pedal. But it happens on flat roads also. The stability control lights comes on, & I have to pull over with residual speed put suv in park, turn engine button off & wait for seat to return to neutral position then restart. This had happened at least 12 times & mostly in dry conditions while driving straight with no lane changes. Dealer could not duplicate & find the problem, visited them 4 times so far. Otherwise it will not start the engine.
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 t…

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!

I HAVE NOTICED EXHAUST FUMES IN THE CABIN WHEN DRIVING. I DRIVE BOTH HIGHWAY AND CITY, BUT IT IS WORSE ON THE HIGHWAY. I STARTED FEELING TIRES AND FOGGY HEADED EVERY TIME I DROVE. I TRIED RECYCLING AIR AND OPEN AIR BOTH BUT DIDN'T SEEM TO HELP. I WENT TO THE DEALERSHIP FOR OIL CHANGE AND TOLD THEM ABOUT THE PROBLEM. SERVICE CONCIERGE SAID THEY HAD ANOTHER 2016 MKX IN AT THAT TIME WITH THE SAME PROBLEM. I WAS TOLD THEY COULDN'T LOOK AT MY VEHICLE FOR OVER TWO WEEKS AND WOULDN'T HAVE A LOANER CAR UNTIL THEN. I TOLD THEM I WAS CONCERNED ABOUT DRIVING WITH THE PROBLEM AND WAS OFFERED TWO OPTIONS... LEAVE IT THERE UNTIL THEY COULD LOOK AT IT, WITH NO LOANER CAR, OR FOR TIMES SAKE TAKE IT TO ANOTHER DEALERSHIP. THIS IS UNACCEPTABLE AND A LIABILITY IN MY OPINION.
WHILE DRIVING ON CITY STREETS, THE ENGINE UNEXPECTEDLY QUIT AND THE GEARS SWITCHED FROM DRIVE TO NEUTRAL ON ITS OWN. THIS HAS HAPPENED 5 TIMES SO FAR. IT IS DANGEROUS AND COULD BE LIFE THREATENING.

IN MAY AND JUNE OF 2019 ON 2 DIFFERENT OCCASIONS, OUR 2016 LINCOLN MKX IGNITION 'TURNED OFF' ON ITS OWN WITHOUT ANY INPUT BY THE DRIVER WHILE USING CRUISE-CONTROL ON A CROWDED HIGHWAY GOING 75 MPH! WHEN IT OCCURRED, A TEXT MESSAGE WAS DISPLAYED SUPERIMPOSED OVER THE TACHOMETER THAT READ: 'CAUTION: IGNITION TURNED OFF'. FORTUNATELY, WHEN IT TURNED OFF, THE CAR AUTOMATICALLY SHIFTED INTO 'NEUTRAL' INSTEAD OF 'PARK', WHICH IT DOES AUTOMATICALLY WHEN THE IGNITION SWITCH IS USED TO TURN THE CAR 'OFF'! AFTER IT SHUT OFF, WE COASTED IN 'NEUTRAL' WITHOUT POWER BRAKES OR POWER STEERING WHILE SURROUNDED BY MACK TRUCKS AND OTHER CARS. THANK GOD THERE WAS A SHOULDER ON THE ROADWAY WHERE WE COULD SAFELY PULL OVER. BEFORE WE COULD ATTEMPT TO RESTART THE CAR, WE HAD TO COAST TO A COMPLETE STOP, PUT THE CAR IN 'PARK', DEPRESS THE BRAKE PEDAL, AND PRESS THE IGNITION BUTTON. HAD WE BEEN IN A WORK-ZONE W/CONCRETE BARRICADES AND NO SHOULDER, WE COULD HAVE BEEN RUN OVER/KILLED BY A MACK TRUCK AND/OR OTHER CAR(S) APPROACHING FROM BEHIND AT HIGH SPEEDS. THE SERVICE MANAGER AT OUR LINCOLN DEALERSHIP SAID THEY HAVE NEVER HEARD OF THIS OCCURRENCE, BUT WE EASILY FOUND TWO (2) WEBSITES DISCUSSING THIS ISSUE REGARDING THE MKX. WE CAN ONLY WONDER HOW MANY PEOPLE MAY HAVE ALREADY DIED WITH NO EXPLANATION ABOUT WHY THEY WERE AT A FULL STOP ON A BUSY HIGHWAY. BECAUSE WE RESTARTED THE CAR, THE SERVICE MANAGER SAID THE "ERROR" HISTORY IN THE COMPUTER WAS ERASED - BAD PROGRAMING! BOTH TIMES OUR INCIDENTS HAPPENED, WE HAD BEEN DRIVING ABOUT AN HOUR ON THE HIGHWAY. THE CAR HAS BEEN 'IN THE SHOP' AT THE DEALERSHIP FOR 2 WEEKS, AND WE ARE STILL AWAITING AN EXPLANATION AND FIX. I'M NOT SURE I'LL EVER FEEL CONFIDENT/SAFE ENOUGH TO DRIVE IT AGAIN!

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.

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.
