2018 Lincoln MKZ Recalls, Ratings & Complaints

Incident: June 3, 2026 · Filed: October 22, 2026

Around end of May or beginning of June 2026 a check engine light came on in our 2018 MKZ. The code showed cylinder 3 misfire. We called our local Ford dealership for diagnosis. We almost didn't get there as it started to overheat on the way. Once at Ford they diagnosed it with coolant intrusion in cylinder 3. They said this was a known issue and needed a new block. $11,500 for replacement. They said driving it could cause catastrophic problems to the vehicle and possibly the passengers in it. The vehicle had 65,873 miles on it at time and once home it has stayed in the garage since. They said warranty was over and to call Lincoln for assistance programs as it was a known safety defect. I did call and Lincoln denied any help with repairs.

I recently have been losing antifreeze, The car stared to overheat, the P303 engine code came on. The car hasn't been inspected yet but my mechanic said it's a sign of a long or short block issue. I've been looking the problem up. It seems to be a problem with many of these cars, a known issue with the card from 2017-2020.

While driving, the car stalled. I could not restart it. It was towed to Lincoln Dealer and determined that coolant had leaked into the cylinders and seized the engine. This is a known defect on the Ford EcoBoost Engine. Fully aware of the defect, Ford redesigned the engine in 2019 for later models. I am now faced with the huge expense of having Lincoln replace the engine. Ford needs to take responsibility and pay for this. Please help me.

The contact owns a 2018 Lincoln MKZ. The contact stated that while driving approximately 30-35 MPH, the engine overheated. The contact pulled over and became aware that the coolant reservoir was empty. The contact added coolant to the coolant reservoir. The vehicle was taken to an independent mechanic, where it was determined that there was coolant leaking into the cylinder, which caused engine failure. The vehicle was taken to the local dealer, where it was diagnosed, and the engine was replaced. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 80,000.

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. Hard starts after fuel refills.

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.
