  So I bought this car in February of last year. Since I've had it june I had to do a head gasket. Another time the high speed fuel pump had bolt come loose and oil went everywhere causing a fire. Had transmission intercooler line do the same thing. Additional fire. And just recently I problem that was supposedly fixed already wasn't and flywheel broke leaving me stranding in a parking lot for 4 days dropping transmission. The dealer didn't put back all the parts correctly either.

  2017 Lincoln MKZ had the "Auto Hold" on and the car came to a complete stop at an intersection with a red traffic light. One other vehicle was in front of me and we had been stopped for at least 30 seconds. Without notice the Lincoln MKZ quickly lunged forward and struck the vehicle in front of me. I kept applying the brake but the car would not stop, it kept hitting the car in front 3 times before it stopped. Auto Hold button was still illuminated. The car was then turned off. The person in the car in front of me stated that they thought I was hit from behind and pushed into their car. I also thought that I was hit from behind and pushed into the car in front. There were no injuries. If I would have been the first car at the light, chances are my car would have been T-boned. I have not driven the car since the incident. No warning signals were given prior to the incident. I would like to have the EDR , black box, evaluated to determine why the Auto Hold malfunctioned. Air bags did NOT deploy. The car is scheduled for service on January 10, 2022.

• 12/01/2025· STEERING

  After filling up with gas, started the vehicle & it displayed SEVERAL warnings regarding the steering, stability control, etc. Only about 2 miles from home. Started driving home & the steering wheel was variably going from fairly difficult to turn to VERY difficult to turn. Got within about 150 feet of my home & could not turn the steering wheel AT ALL. Tried multiple times to back up / go forward while attempting to move the steering wheel in hopes of getting in my driveway, to no avail. Ended up having to call a tow truck & having vehicle taken to a local dealership.

  Coolant leaked into cylinders causing my engine to regularly overheat, forcing me to replace the engine at about 78,000 miles. Although I didn't realize it at the time, the first indication of a problem was at 72,737 miles (just 2,737 miles out of warranty), which is when I had the first overheating incident. According to my research, Ford has known about this problem for many years, and it affects many models over many model years, but they have yet to address the problem with the public. I was fortunate in that I didn't have a fire or an accident due to this known problem. Ford has issued several Technical Service Bulletins about it, the most recently being 22-2229, which is attached. Lincoln assisted me with covering the engine replacement, but in total, I am out $3,864.80 due to this problem.

  The torque converter/flex plate is bad rattles and apoarently can cause an accident. There are recalls for this same year same motor and midel but my vehicle is not included but should be. I had it checked by undioendent mechanic who confirmed issue. I have read numerous post online with the same issue with theirs also saying it not included in recall how is thus posdible obviously there is an issue and others should be covered. After vehicle started making noise and i seen it could cause a crash it was parked til looked at. How do they decide which ones are included in recall when some others made at same time are having same issue. This is crazy they arent included too many of the same issues happening to the same vehicle.

  I was driving and started smelling toxic fumes come inside my car, steering wheel started jerking. I didn’t think much of it until my 2 year old daughter in the backseat was looking as if she was about to pass out. Her eyes started rolling and her words were slur, more slur than normal. I immediately pulled over and saw the fumes were coming from my tail pipe. It was a huge cloud of smoke. It was my car that was the problem. I had to leave my car on the side of the road and get someone to take us home. It wasn’t safe to drive in the condition it was in. The next day I got it towed to the mechanic and he said my car lacked coolant and the engine needs to be replaced. I looked online and saw that this was an ongoing problem for the make and model of my vehicle and Ford is aware of it. The mechanic quoted my thousands of dollars to get it repaired. Ford won’t help. This incident could’ve killed my daughter and me. PLEASE HELP MAKE MY CAR A RECALL ON THE ENGINE! I have no transportation.

  Incident Summary – Vehicle Fire Date of Incident: Thursday, September 4, 2025 Context: I was driving to a scheduled service appointment for my car at Murgado Lincoln Dealership of Chicago Events Leading Up to the Fire While driving, I heard loud metal noises coming from under the hood. The sound was either metal pieces falling off or grinding/chomping metal against metal. Concerned by the noises, I pulled over to the side of the road. Smoke and Fire Once stopped, the car began emitting gray smoke, which quickly turned into black smoke. The black smoke entered through the dashboard, filling the interior cabin. I realized the vehicle had caught on fire. Immediate Actions Taken I quickly gathered personal belongings from inside the car. I was lucky to have evacuated the vehicle immediately to ensure my safety, despite inhalation of potentially hazardous chemicals due to the fire/ plastic of the car. I then called 911 to report the fire and request emergency assistance. The car continued to catch fire and then there was a minor explosion, as the Chicago fire department battled the fire.

  My engine is overheating, causing my steering wheel to jerk while on the highway. Took to dealership and they said loss of coolant and could potentially cause a fire if not treated. Looked online and saw that Ford is aware of the problem but will not correct it. The dealership is asking me to pay $8,000 to fix it for Ford initially putting in a faulty engine. I had to stop my car because smoke was coming out the tailpipe. The car isn’t safe to drive.

• 09/09/2022· SERVICE BRAKES

  On Tuesday, March 1 2022, as I was attempting to stop at a stop sign, I noticed loss of pressure on the brake pedal. As I accelerated and applied my brakes again there was no pressure feedback on the brake pedal and my vehicle took a prolonged time and distance to stop. After a few minutes, a warning message appeared on the dashboard to let me know of low brake fluid. After I got the vehicle home, I noticed a lot of brake fluid in the driver's front wheel well. Upon further inspection, a rupture in the line at the metal crimping was evident. The event happened as I was coming home from ice hockey practice with my 5 yr old and 8 yr old in the vehicle. The roadway that the failure occurred at was a service road to I-35E in Farmers Branch which at that time of day has moderate traffic moving at high speed. Had the brake blown out a few minutes later, I would have been on I-35E with my children. The speed limit on that road is 70 MPH and it was the tail end of rush hour which means a mix of slow traffic and high speed traffic requiring the ability to brake at a moments notice. I still have the faulty brake line in case anyone needs it for inspection.

• 09/04/2026· UNKNOWN OR OTHER,ENGINE

  I purchased a 2017 Lincoln MKZ and began experiencing serious engine problems, including repeated overheating and an engine misfire. The vehicle developed a check-engine light and a P0301 misfire code. I was advised by a repair shop that the vehicle has a serious engine problem and that the engine needs to be replaced. I am concerned that the overheating and engine problems could cause the vehicle to suddenly lose power or suffer complete engine failure while I am driving. If the engine loses power unexpectedly while I am traveling in traffic, I could be unable to accelerate or safely move out of the way of other vehicles, creating a serious safety hazard for me, my passengers, and other motorists. I contacted Lincoln regarding these problems and asked the manufacturer for assistance, but Lincoln refused to provide assistance with the issue. I am now left responsible for addressing a potentially serious engine and safety problem. I am requesting that NHTSA document and investigate these engine, misfire, and overheating problems to determine whether they may be related to a safety defect affecting other 2017 Lincoln MKZ vehicles.

  2017 Lincoln MKZ with 53k miles check engine light comes on and dealership diagnostic shows leaking coolant in cyl #2/needs motor. Car out of warranty so cost of repair is out of my pocket. Lincoln has known about this since 2016...they leased the car out in 2017 and then sold it to me in 2019 KNOWING there was a defective engine in the vehicle but didn't do or say anything about it...NEVER any recall. How is it that there are 100k 2021-2022 trucks and suv's being recalled due to engine issue that could "lead to catastrophic engine damage resulting in a loss of power". I could of suffered a loss of power as well with the defective engine that was in my car. How is this sudden recall on these trucks and suv's any more important or severe than all of the Ford/Lincoln vehicles that had engine issues? This could have been easily rectified early on seeing they knew about this issue from the beginning. I want my money back I paid to get my engine repaired.

  We are submitting this vehicle safety complaint regarding a dealer-confirmed coolant-intrusion failure in our 2017 Lincoln MKZ equipped with the 2.0L EcoBoost engine. The vehicle had approximately 60,063 miles when presented to Parks Lincoln of Longwood. The vehicle developed a check engine light, rough running, shaking, and recurring misfire symptoms. Two ignition coils had recently been replaced, but the symptoms returned. The vehicle also produced white exhaust smoke on startup after sitting for several days. Because the rough running was so severe, the vehicle was ultimately towed to the Lincoln dealership on a flatbed. Parks Lincoln's Repair Order 2684839/1 documents DTC P0301. The technician states that, pursuant to TSB 22-2229, a coolant pressure test and cylinder inspection were performed; coolant intrusion was found in cylinder 1; and a long-block engine is required to properly repair the concern. Lincoln TSB 22-2229, NHTSA Manufacturer Communication No. 10214126, describes coolant intrusion in certain 2.0L EcoBoost vehicles including 2017-2019 Lincoln MKZ models. The bulletin identifies white exhaust smoke, rough running, and misfire codes, including P0301, and directs replacement of the long-block engine assembly when the condition is confirmed. Our safety concern is that coolant intrusion can progress from rough running and misfire to loss of engine performance or engine failure while the vehicle is in operation. In our case, the symptoms became severe enough that we did not consider continued driving appropriate and had the vehicle transported to the dealer. We ask NHTSA to add this complaint to its defect database and evaluate it together with other reports involving 2.0L EcoBoost coolant intrusion, misfire, loss of power and engine failure. We can provide the complete dealer repair order, estimate and additional records upon request.
