2017 Lincoln Mkz

On August 8, 2022, the Office of Defects Investigation (ODI) opened this investigation based on 50 Vehicle Owner Questionnaires (VOQs) alleging front brake jounce hose ruptures on model year (MY) 2013-2018 Ford Fusion and Lincoln MKZ vehicles. A ruptured front brake hose results in a brake fluid leak. As a result, the driver may experience an increase in pedal travel and a reduction in the rate of deceleration, increasing the risk of a crash. It should be noted that the subject vehicles identified fell outside the scope of NHTSA Safety Recall 20V-469, which addressed front brake hoses rupturing on certain MY 2015-2018 Ford Edge and 2016-2018 Lincoln MKX vehicles. The result causes a brake fluid leak, lengthening the distance needing to stop the vehicle, increasing the risk of a crash.On March 10, 2023, Ford Motor Company (Ford) submitted to NHTSA Safety Recall 23V-162 (Ford Recall 23S12) to address front brake jounce hoses that may rupture. Ford found the rupture occurs from a localized failure of the internal reinforcement braid due to cyclic fatigue through tensile/bending and torsional inputs during suspension and steering articulations. The supplier for the front brake jounce hoses is Hitachi. This recall affects the subject vehicles equipped with non-hybrid engines and the suspect front brake jounce hoses (a total of 1,280,726 vehicles). The recall covers subject vehicles built from February 3, 2012 to July 19, 2017 when the suspect hoses were used in vehicle production. The remedy is for dealerships to replace both front brake jounce hoses with new hoses that have a revised braid material at no cost. The vehicles equipped with hybrid engines are excluded from the recall because the internal hose pressure is much lower due to the regenerative braking provided by the hybrid brake system. No failures of brake hoses on hybrid vehicles have been reported to ODI or Ford.Ford's actions address ODIs concerns at this time. Hybrid vehicles will be monitored for related failures. The agency reserves the right to take further action if warranted by new circumstances.The 103 ODI numbers cited above can be viewed at NHTSA.gov under the following ID numbers:11511014, 11510867, 11510318, 11509030, 11505993, 11504989, 11504400, 11502147, 11502082, 11501820, 11501283, 11498439, 11498296, 11496842, 11496335, 11494931, 11494851, 11494252, 11493001, 11492084, 11492070, 11491444, 11491274, 11488858, 11488027, 11487627, 11487416, 11487233, 11486150, 11484924, 11484526, 11484080, 11483948, 11483926, 11483739, 11483723, 11482773, 11482690, 11481077, 11480788, 11480294, 11480052, 11479338, 11479334, 11479252, 11479247, 11479187, 11479094, 11479048, 11478985, 11478953, 11478729, 11478216, 11476892, 11476282, 11470558, 11468994, 11467109, 11466294, 11462746, 11461217, 11456065, 11455367, 11444848, 11436419, 11436376, 11430685, 11428329, 11425083, 11421026, 11420738, 11420735, 11420298, 11418197, 11403926, 11397549, 11366991, 11366757, 11361016, 11359968, 11354569, 11352165, 11350344, 11348799, 11343929, 11343205, 11331947, 11329020, 11319596, 11310529, 11292271, 11288455, 11254787, 11253479, 11253244, 11234622, 11230669, 11230050, 11228240, 11221111, 11143630, 11129392 and 11120228.

I am reporting a catastrophic engine failure and engine-compartment fire involving my 2017 Lincoln MKZ Select, equipped with a 2.0L EcoBoost engine, VIN [XXX]. The vehicle had approximately 99,864 miles when the final failure occurred. Shortly after I purchased the vehicle, the original engine developed severe overheating, loss of cabin heat, white exhaust smoke, misfiring, and coolant intrusion. On December 16, 2024, at approximately 95,354 miles, the vehicle was taken to Murgado Ford Lincoln of Chicago. The dealership documented diagnostic codes P0303 and P0316 and determined that coolant was entering cylinder No. 3. Pursuant to Ford Technical Service Bulletin 22-2229, the dealership replaced the long-block engine and related one-time-use components. The replacement service-engine assembly was identified on the repair invoice as part No. J2GZ-6006-E. The vehicle was returned to me on approximately January 30, 2025. After the engine replacement, the vehicle continued to experience serious problems. Within days, it stalled in an intersection, produced white smoke, lost cabin heat, and had to be returned to the dealership. The vehicle later continued to exhibit hesitation, harsh shifting, loss of power, and other abnormal drivability symptoms. On September 4, 2025, while I was operating the vehicle under normal driving conditions in Chicago, I heard a sudden loud metallic grinding or mechanical noise coming from the engine area. Gray smoke then began coming from the vehicle and quickly progressed into heavy dark smoke. A fire developed in the engine compartment, forcing me to stop and exit the vehicle. The fire rapidly intensified and was followed by an explosion or explosive sound. There was no collision that initiated this incident. The vehicle sustained catastrophic fire damage and was rendered a total loss. The failure occurred only approximately seven months after the replacement long-block engine was installed and after I had repeatedly experien INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

I own a 2017 Lincoln MKZ equipped with the 2.0L EcoBoost engine. At approximately [MILEAGE] miles, the vehicle began experiencing loss of coolant, rough running/misfire, shaking/rough start, and reduced engine performance. The vehicle was diagnosed by a Ford/Lincoln dealership as having coolant intrusion into the engine/cylinders and/or engine block failure, requiring engine/long-block replacement. The estimated repair cost was approximately $8000. This creates a safety concern because coolant intrusion can cause misfires, overheating, engine damage, and possible loss of power while driving. Ford/Lincoln has issued Technical Service Bulletin 19-2346 and superseding bulletin 22-2229 for 2017–2019 Lincoln MKZ vehicles equipped with the 2.0L EcoBoost engine. These bulletins describe low coolant, white exhaust smoke, rough running, misfire codes, overheating codes, and coolant intrusion into the cylinder, with the prescribed repair being long-block engine replacement. Despite this known documented condition, Lincoln/Ford denied assistance because the vehicle is outside warranty. I am reporting this as a potential safety defect because the failure can occur without adequate warning and may cause engine overheating, misfire, or loss of power while the vehicle is being operated.

2017 Lincoln MKZ was taken to Community Ford Lincoln of Bloomington (Auto Vest II LLC), Bloomington, IN for service on 05/01/2026. No ABS, Traction Control, or AdvanceTrac warning lights were present at drop-off. After the vehicle was returned, all three warning lights were illuminated. The ABS/stability control system had been damaged during the service visit. Diagnostic codes C0031:07 and C0031:15 (left front wheel speed sensor circuit fault) were confirmed in writing by the dealership service manager on 06/09/2026. The dealership denied responsibility. An independent Ford/Lincoln dealer (Tom Roush Lincoln) estimated repair at $310. The servicing dealer offered only partial reimbursement of $169.45. The ABS and stability control systems are safety-critical. Their failure compromises emergency braking performance and vehicle stability, putting driver and other road users at risk. The vehicle has been unavailable for normal use since [XXX]. The problem was confirmed by an independent Lincoln dealership. The vehicle is available for inspection.

Took car into Ford dealership service because the check engine light came on. The car was sounding a little rough also. When they called me, I was expecting a tune up or just a sensor issue, but I was told that I needed a new engine! The tech found dtc P0302 for misfire on cylinder number 2, found coolant on spark plug. Cylinder #2 was cracked and leaking coolant into it. Was told it would lead to catastrophic failure. Was told I needed a long block replacement at the tune of $9,000. The service tech called Ford to help with the costs, but since I didn't have an extended warranty, they wouldn't do anything. The car has been barely driven and taken well care of. I bought it in 2019 with 12k miles and now in 2026 it only has 69k miles. I have researched and found out that this is a systemic issue. Had I not replaced the engine it could of been catastrophic! I have been with Ford since I started driving in the early 80's. This is unacceptable. According to several reports, this has been reported many times (maybe thousands?). I wonder how many are NOT reported. Ford needs to reimburse for the defective engine.

The contact owns a 2017 Lincoln MKZ. The contact stated that while driving approximately 40 MPH the brake warning light had illuminated and the brake pedal extended to the floor and the vehicle did not immediately stop while pressing the brake pedal. The vehicle was slowly driven to a nearby garage who diagnosed that the rear brake hoses had failed causing brake fluid leak from the vehicle and the brake master cylinder had also failed. The mechanic informed that both rear brake lines were installed making contact with the transmission and eventually became damaged. The rear brake lines and master cylinder were replaced. The local dealer and manufacturer were not notified of the failure. The failure mileage was 153,000.

Some 2016-2017 Edge/MKX, 2017 Continental/Fusion/MKZ vehicles equipped with a 2.7L or 3.0L EcoBoost engine and built on 1-Apr-2016 and through 1-Jan-2017 may exhibit white or blue smoke from the exhaust, rough idle in neutral or park at normal operating temperature or after a hot restart. The vehicle may also exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0300, P0301, P0302, P0303, P0304, P0305, P0306 and/or P0316, P0524 and/or P06DD with excessive oil consumption. Oil consumption may be 1 Liter (1 quart) in less than 4,800 km (3,000 miles). This may be due to the valve guides. To correct the condition replace the cylinder heads. During service and repair, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in timing gear failure and engine damage. Replacement of the bolt is critical to the repair. The bolt requires a 4 stage torque procedure. Hold the pulley using a universal holding tool OTC 4754 or equivalent. Refer to Workshop Manual, Section 303-01. The bolt torque procedure can be
