2018 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.

The engine light came on. The car suddenly wouldn’t go past 35 mph . Thankfully I was on a local road. I had it towed to the dealer and was told that the engine needed to be replaced because coolant leaked into the engine. There were no warning lights except the day of . The car did not give any indication of a leak. Nor was it running hot. Everything was functioning fine.

Scanned codes P0741, P1450, P1744, & P2196. Check the transmission fluid level and condition. No fluid drained from hole, added a little fluid, and retrieved a sample of the fluid. The fluid is very dark. Identifix states, if the fluid smells or has the appearance of being black due to internal clutch slippage, the transmission should be replaced or overhauled. If the transmission fluid is in good condition and found to be at the proper level, monitor the Torque Converter Clutch actual slip (TC_SLIPACT) and TCC desired slip (TC_SLIPDSD) PIDs through the scan tool as the vehicle is driven noting these reading should stay relatively closed together expecting the reading to show to be within 10 RPM of each other. Seeing the values spread apart supports the setting of the P0741 and P1744 codes. Note that excessive TCC slip can be caused by multiple internal factors including mechanical failure of the TCC solenoid, an issue of a valve body component that does not hydraulically react to the activation of the solenoid, a leaking valve body gasket, a leaking input shaft seal, or failure of the torque converter seal. There are no external testing measures that can be taken to verify any of these as the specific cause of the concern. Per the test drive, the difference between actual and desired TCC slip was 100-125 rpm.

My 2018 Lincoln MKZ began misfiring on startups. Eventually the check engine light came on with a code of P0302. About a week later while driving, the engine temp gauge reached the hottest temp reading on the gauge. I had to immediately pull over. Upon pulling over I immediately checked the coolant level in the overflow reservoir and it was empty. After refilling with coolant I was able to drive the car home. Over the next few days I monitored the coolant level but at the same time the car was experiencing rough startups and smoke coming out of the exhaust upon startup. Sometimes turning the engine off and restarting it would stop the smoke, but sometimes it wouldn't. I began doing some research and discovered, Technical Service Bulletin (TSB) 19-2346, which explains my exact experience with my 2018 Lincoln MKZ. I have yet to take my car to the dealership for repairs due to the costs that are expected to have this issue resolved. Documents in the legal case, Miller, et al. v. Ford Motor Company (Case No. 2:20-cv-01796) claim that Ford was aware of this defect in their vehicles dating back to 2010. I purchased my 2018 Lincoln MKZ back in 2019.

My Check Engine Light came on, I took my car to the dealership that I have using for eight years with less than 38k miles on it and I was told by the service technician who gave the diagnose as, there was coolant in the cylinder where the spark plug #3 is housed. He stated that the car is misfiring and I was told I needed to get an new engine replace to correct the problem. I was given a Service Bulletin stating the manufacturer knew of the problem with this model. I talk to the dealership service manager and questioned why no indication, clue, or suggestion was told to me of the problem with that type of engine. I have not contact my insurance company and I don't if they have information on the problem of the engine problem. I did tell the service technician on routine maintenance for the car that is running "rich" in using gas. In May of this year is when the engine problem started, 3 weeks before actually being eight years officially, no other indication lights came. I drive to work on the streets and freeway everyday.

The car had an internal transmission failure and caused most of the transmission fluid to leak out between inspections. Upon removing the cv axle on driver’s side, the seal was fine and replaced along with cv axle. The fluid drained and was only about half a liter (needs about 4.5L normally). After servicing the transmission fluid, the dealership did their assessment and came to the following conclusion. “ Good Afternoon Sir We found the transmission system requires replacement due to an internal fault, including damage to the transfer shaft and bearings, with potential additional internal damage. Replacing the transmission can help restore smooth gear shifting and overall drivetrain functionality. To replace the transmission, you are looking at $9000.00 out the door. My apology on taking much longer to diagnose this properly. If you have any other questions please let me know. ” The drastic transmission failure which makes noises and engages and disengages while on cruise control shows the failure internally. Many metal pieces were found among the fluid when drained. This could and still can easily leave someone on the middle of the road with no time to drive to the shoulder. Car still has less than 100k miles with the severe transmission failure and the fluid leak which occurred prior to the transmission making noise. Essentially, the internal components caused the leak which the caused even more damage. I’m quoted $9,000 for the repair which occurred really early in the car’s life. I do a lot of longer trips away from home and can easily be left stranded in the middle of nowhere or even cause huge accidents when in heavy fast moving traffic if I lose drivability or if metal components fly off. The cv axle moves in and out of the transaxle side meaning the shaft can pop off as well.

Wheel lug nuts get swollen due to the material used causing problems when the wheels need to be removed. I was lucky to not be in an emergency situation needing to change a wheel out. This could have easily happened and I would have been unable to change a wheel on the side of the road. I went to Costco to get my tires changed and they refused to take the wheels off because the wheel lug nuts were ALL swollen and could cause issues on removal or/and installation. They were afraid of stripping the hardware during removal or being unable to torque to spec during installation. The replacement of the wheel lug nuts with parts that wont recreate the problem was about $90 and taking an extra day for the tire replacement appointment plus me replacing it on my own saved on labor.

Car only has 97K miles and the transmission fluid has been leaking for some time causing loud noises from the transmission which took time to locate. The transmission leaked fluid and only had about half a liter of fluid when it should be around 4.5 liters. The fluid leaked from the transmission on the driver cv axle seal. The car shows no lights on dash of any kind. I discovered the leak after the noises were really bad while driving one day. I put the car on my ramps and got under and discovered the driver cv axle damaged and looked like electrical tape was jammed in the cv axle near the transfer case/transmission. Upon closer inspection the leak of transmission fluid was even more obvious. There is no dip stick for the transmission so I decided to drain and see and there is evidence of only about half a liter of fluid. The fluid is black and full of metal particles. This is concerning because the depth of damage is unknown until the car is repaired; this repair would include a new seal, cv axle and fluid replacement. There is no way to know what internal damage was done and this was such a short period of time. Periodic inspections are conducted on the vehicle when oil changed are completed. This can easily lead to transmission failure and the risk is exponential due to it happening regardless of where you are on the road with the unknown weather and road conditions. Miles reflected is when the leak was discovered after the noises. 97,839 miles.

For 2015-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual (WSM), Section 303-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.
