2019 Lincoln Mkz

In August 2026, my 2019 Lincoln MKZ equipped with the 2.0L EcoBoost engine, with approximately 39,000 miles, began experiencing repeated coolant loss, rough shaking during startup, engine misfires, temperature-gauge fluctuations toward hot, and an “Engine Coolant Over Temperature” warning while the vehicle was being driven. The warning appeared and then cleared, creating concern that the vehicle could continue operating without a persistent warning even though the engine was overheating. The climate-control system also began blowing hot air while the air conditioning was selected. Before the over-temperature warning, coolant had required frequent replacement, at times approximately once per week. An authorized Lincoln dealership performed diagnostic testing and confirmed coolant intrusion into the engine cylinders. The dealership advised that the failure matches the condition addressed in Ford’s technical service bulletin concerning coolant intrusion in certain 2.0L EcoBoost engines. The prescribed repair is replacement of the engine long-block assembly. This condition creates a safety concern because coolant entering the cylinders can cause misfires, overheating, severe engine damage, and potential loss of motive power while driving. The vehicle is currently at the authorized Lincoln dealership, and the failed engine should remain available for inspection until it is replaced. No crash, fire, or injury occurred. The manufacturer declined repair assistance because the vehicle was outside the applicable time limit, and the estimated engine replacement cost is approximately $9,620.

On XXX, the engine in my 2019 Lincoln MKZ (Mileage 58,089) with the 2.0L EcoBoost engine suffered a catastrophic, sudden failure while driving. The vehicle began to overheat & run extremely rough, triggering multiple warning lights. It is now inoperable and unsafe to drive. The vehicle was towed to a Lincoln dealership (Tasca Lincoln in [XXX]) for diagnosis. The work order number is RO #XXX. The dealership confirmed the failure is due to a well-documented manufacturing defect known as "coolant intrusion," where the engine block cracks internally, allowing coolant to leak directly into the engine cylinders. The diagnostic trouble codes stored were P0217 (Engine Overheat Condition), P0302 (Cylinder 2 Misfire Detected), & P0316 (Misfire Detected on Startup). This issue is specifically addressed in Ford's own Technical Service Bulletin 19-2346. This coolant intrusion defect creates a critical safety hazard. The engine can lose its coolant and fail without any prior warning, leading to a complete loss of power while the vehicle is in motion. A sudden seizure of the engine at highway speeds could cause a catastrophic accident, endangering myself, my passengers, & other drivers on the road. Estimated Cost for Repair: $10,781.40 (for complete engine replacement). I contacted Lincoln Customer Relations (Case #XXX) to request assistance with this known manufacturing defect. I was informed that there is no goodwill assistance available & that my case was being forwarded to their internal Vehicle Safety Division. This confirms that Ford is aware this is a serious safety issue. This is not a normal wear-and-tear failure; it is a fundamental defect in the engine's design that Ford has acknowledged internally through its service bulletins. An engine should not fail catastrophically due to a manufacturing defect on a [XXX] vehicle. I urge the NHTSA to investigate this defect to determine if a safety recall is warranted to protect the public.

The shifter cable bushing was broken. Car would not move out of Park. Same as Recall 22543 but this vehicle was not included. I have sent this before with the repair order from the dealership but the mileage was incorrect on that form by the service adviser. I am enclosing the corrected mileage with the receipt

Technical Service Bulletin 19-2387 My vehicle has this defect which is an ongoing problem and at the time of this correspondence my vehicle has under 13,000 miles. Seepage around the perimeter of the oil pan which in time will result in a steady leak and in turn loosing enough oil will cause engine damage. Technicians refer to this as the oil pan sweating. As per the Technical Service Bulletin this problem exists on 2017 to 2019 Lincoln MKZ 3.0 which Ford installed a plastic oil pan on all new vehicles to reduce the weight of the vehicle. The 2017 to 2019 Lincoln MKZ 2.0 were fitted with metal oil pans and there is no issue. I notified Lincoln customer service and they are aware of this problem yet a recall has not been issued. This is a manufacturer defect and Ford should take responsibility to correct this problem. A recall should be issued. Thank You for your attention on this matter.

I took my car to a Lincoln dealer because I was getting a drive control malfunction error every time I started my car. After a couple of days, I called the service dept. for a status update on the repair. The dealer told me that the car could not be repaired because they don't have a replacement part. They had me call the Lincoln Concierge, who also told me the same thing, they did not have a replacement part. When I researched the error message, is said that it is dangerous to drive the car without the repair. When I bought the car, I also purchased an extended warranty, which is now not worth the paper it's printed on. My car is only 7 years old and only has 53,000 miles, why can't they repair my car? The car is currently still at the dealer, so I do not have any paperwork for now.

Some 2019-2024 Ford and Lincoln vehicles equipped with SYNC3 may experience various connectivity concerns with The Ford App Lincoln App including but not limited to: missing activation prompt pop-upon the vehicle's center display screen when attempting to activate vehicle through The Ford App Lincoln App, incorrect location global positioning system GPS reported through The Ford App Lincoln App, problems with remote commands being performed through The Ford App Lincoln App and or incorrect data information reported on The Ford App Lincoln App. These symptoms will be accompanied by diagnostic trouble code DTC B156D 89 in the TCU. This may be due to the accessory protocol interface module APIM software. To correct the condition, update the APIM software.

Some 2015-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. Pinpoint test HK in the Powertrain Control and Emissions Diagnosis (PC/ED) or in Section 303-14 of the Workshop Manual (WSM) has been updated to address this concern.

Various 2019-2024 Ford and Lincoln vehicles equipped with SYNC 3 may experience a partially or fully black center display screen at start-up using Apple CarPlay or Android Auto. This does not affect rear camera operation. This may be due to interference from the phone being connected into the media hub using a universal serial bus (USB) cable during SYNC system boot up. To correct his condition, advise the customer to disconnect the USB cable from the phone. If the center display screen displays normally, reconnect the phone. If the concern persists, disconnect the phone from the USB cable, cycle the ignition off and open the driver's door so the interior lights come on. Close the door, start the vehicle and wait for the center display screen to boot up past the start-up animation and display the home screen, then reconnect the phone using the USB cable. If the concern persists after this procedure, follow normal Workshop Manual diagnostics for a blank screen concern.
