2018 Lincoln MKX problems

SERVICE BRAKES

I have experienced this issue and it's been 9 months since the first issuance from Ford on this recall. I paid $523 to repair and this is insane since mechanic told me its an OME part so still going to possibly have same issue till recall is handled.

ENGINE

Faulty catalytic converters. Ford has a CSP for the 2018 Lincoln mkx 3.7L engine and only included police driven Mkx's which is totally unfair when they're well aware that Faulty/failing emissions catalytic converters were installed on all of them and they fail and produce p0430 codes regardless of driving habits, I've never driven any of my vehicles harshly and maintain my vehicles, yet since I've owned this 2018 mkx since September of 2024, the rear catalytic converter had to be replaced and now the front catalytic converter is giving the same p0430 permanent code. Its bias of Ford to only extend police vehicles coverage and not regular consumers knowing that this emissions part is faulty because catalytic converters don't normally fail prematurely unless the parts are faulty. The original owner maintained this vehicle before me and I've maintained it since I've owned it, yet the catalytic converter has been replaced 3 times (carfax) which proves its Faulty. My 2005 Lincoln aviator had 303,000 miles before the engine blew, yet the catalytic converter had never been changed and I owned it for 15 years. I'd like an explanation from Ford as to why my 2018 Lincoln mkx 3.7L engine vehicle wasn't included in the CSP19M01. Ive owned a ford Explorer, Lincoln navigator and aviator that were built ford tough but this Lincoln mkx seems to be worse than a BMW. Thanking you in advance for your timely response.

ENGINE

My vehicle has had emissions vehicle since before I owned it up to now. The catalytic converter has been replaced 4 times which is unheard of. Its presently giving the same codes/issues. The last catalytic converter replacement was November of 2024. It has to be a computer programming issue as my mechanic express. Im asking that this be looked into by Ford. I've owned 1973 Ford Pinto as a teenager, a 1998 Ford Explorer, 2000 Lincoln navigator, 2005 Lincoln aviator and now this 2018 Lincoln mkx has been the only vehicle with this type of issue. Maintenance records can prove this vehicle has properly been maintained before and during my ownership. I only use Shell, sunoco and other top tier 87 octane gasoline in this vehicle and have records of that too. P0430 code has come back on even after replacing the purge valve twice, 2025 and last month 2026, then code p0430 came back stating catalytic converter smh.

The rear view camera is intermittent. The camera listed for replacement is F2GZ19G490C. That was a recall item listed for the problem that we are having . It is intermittent and is a safety hazard as indicated in the LINCOLN MKX 2015 THRU 2019. WHY IS IT INDICATED AS NOT HAVING A RECALL TO MY 2018 LINCOLN MKX VIN [XXX] . IT IS THE SAME PROBLEM. THE CAMERA F2GZ19G490C IS THE CAMERA LISTED AS THE REPLACEMENT AND THEY LIST IT AT FORD FOR $560.68. THE REPAIR DEPARTMENT TOLD ME IT WAS OVER $600 AND IT WOULD COST $1300 TO FIX IT. SOMETHING IT IS WRONG HERE BECAUSE i CAN GET THE REPLACEMENT FOR ABOUT $60 DOLLARS. IT LOOKS LIKE A DENIAL OF SERVICE UNDER A RECALL AND A REDICULOUS AMOUNT TO REPAIR THE DEFECTIVE ITEM WITH THE SAME TYPE. i WOULD LIKE TOO GET AN EXPLANATION ON THIS .

Was advised by a law enforcement officer the high-mount stop lamp lens had detatched from the lamp housing. Apparently, the adhesive holding the plastic lens had deteriorated and allowed seperation of the components. The LED circuit board is now exposed to the elements. This without a doubt will cause the CHMSL to fail due to water and salt intrusion. Additionally, the non-diffused LED's are blinding drivers behind this vehicle at night. This failure occurred on the highway, and the lens nearly struck a car behind me.

Subject: Urgent Health Risk Due to Mold in Lincoln MKX & Additional Considerations I'm submitting a formal complaint regarding our Lincoln MKX, purchased in 2018 with an extended warranty valid through 2026. A significant water leak has resulted in extensive mold and mildew buildup, posing severe health risks, particularly to my immunocompromised wife. Despite minimal use of the vehicle, exacerbated by reduced mobility during the COVID-19 pandemic declared by the WHO on March 11, 2020, we've discovered this longstanding issue, indicating it likely existed since purchase. The remediation process requires complete removal of the contaminated carpeting and padding, thorough cleaning of the underlying metal, and replacement with new materials to ensure safety. Efforts to resolve this with Ford/Lincoln have been met with inadequate support, not covering the extent of necessary repairs. Attached documentation and photographs outline the severity of the issue, the health implications, and our struggle for a satisfactory response from the manufacturer. We urge the NHTSA to consider these factors and our vehicle's low mileage as evidence of the defect's pre-existence and the pandemic's impact on its delayed detection. Immediate action is necessary to address this safety hazard.

When I utilize my ac or heat without pressing a certain button after a while I start smelling a burning smell coming through the vents. When I'm outside the vehicle I smell it as well. The smell is hard to pinpoint. A dealership told me that maybe I needed to change my air filters. However the burning smell still would happen just the same. Then they checked to see if anything(such as plastic or anything) was stuck to any components that get hot to no avail. But something is wrong and it's scary. Also my vehicle has a very rough idle which sometimes can feel like a rumble. A tune up was suggested and complete and I still have the same experience. I love my vehicle but growing tired.

NHTSA complaint #11499828 — an unverified report by a vehicle owner.

STRUCTURE:BODY

Vehicle (SUV) floor board and truck had standing water from unknown source. Suspect rear hatch and/or glass roof design allows for environmental contamination to enter. Water travels down to floor and pools. For example, spare tire was found to be submerged. Rear seat and trunk carpeting were moist (saturated) to the touch. Concern: If water in the vehicle is undetected and is allowed to pool for long periods of time, three things will happen: 1. Accelerated corrosion and loss of function for any electrical wiring. 2. Standing water can develop mold, impacting air quality through long term and repeated exposure. Impact of vehicle occupants health. (In our instance, Mom & newborn) 3. Accelerated corrosion of vehicle internal structure. For example, seat fasteners. Item was discovered by third party service center and dealership is investigating root cause now. Dealer commented this is a problem more common with other models in the same family but not the model of this vehicle. No warning or indicator of the problem was present.
