Lincoln MKZ Reliability by YearBest & worst years, problems & recalls — NHTSA data

While driving at freeway speed, my fully closed panoramic moon roof exploded with me and my 5 year old son in the car. Thankfully, the interior shade was closed so no shards of glass fell inside. It sounded like a gunshot and I have front and rear view dash cam video with audio of the incident. You can see glass flying off the back of the car that could have easily damaged another vehicle if one happened to be close enough. I have been without my car for almost three months as it sits in a glass repair shop waiting for a part that is supposedly nationally back ordered. The Lincoln dealership wouldn't even help me. They just pointed me straight to the glass shop while adamantly saying a rock must have hit the top of my car to cause the damage.

My daughter almost killed herself in the car at [XXX]; the steering wheel and wheels got stuck. She's stuck at [XXX] close by [XXX] in the middle of the road, She's already called the mechanic and towing company and his assistant so I can get to work. The car is under my name [XXX] . Car was towed to a mechanic shop. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

My engine has failed at less than 40,000 miles due to coolant leaking into the engine.

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
