2017 LINCOLN MKZ Complaints

At any given time without warning the car will down shift into 4, 3, 2, or 1. It is intermittent but in the last 3 weeks has become very frequent. I have taken it to the dealership. They state that it is the internal clock spring in the the steering column. They have told me that my power train warranty and/or technology extended warranty will honor the replacement, so I looked up possible recalls on this model vehicle and found there is in fact a recall on the steering column internal clock spring but the concern was on the airbag. The issue I am having with the downshifting is going to cause someone to rear end me. There is no pre-warning. I have driven on service roads, the interstate, my neighborhood streets, and on highway. It seems to happen more as I am following the curve of the road, or when I am turning or changing lanes/merging onto interstate. If I am at a complete stop and turn either left or right it will downshift to 1. I am also concerned to the extent of damage this may be doing to my transmission and engine, as it happens during speeds of 45 to 75 mph on the highways and interstate. I do have video on my phone of this behavior and I can send it to you if I have an email address you have access to. I have placed the most current date of this behavior in the incident box, however this has happened numerous times over the past few months, It just wouldn't give a code to any dealerships for diagnosis.

I purchased this vehicle on November 11, 2024. About one month later, I began experiencing severe problems. The engine started overheating, which marked the beginning of a downward spiral of issues. To address the overheating, a new engine was installed by Murgado Lincoln dealership, which took approximately 48 days to complete. While the new engine resolved the overheating, a serious transmission problem has persisted and worsened. Since I purchased the car, the transmission has been slipping constantly, shifting gears on its own unpredictably, making loud noises under the hood and throughout the entire vehicle. These issues create a major safety hazard, putting me and others at significant risk. On June 25, 2025, I was involved in a hit-and-run incident that likely worsened the vehicle’s condition. During this incident, the side airbags on both sides of my vehicle deployed, but the front airbag did not deploy at all, which is highly concerning and increased the danger during the impact. Additionally, the car has a cracked shock absorber head, likely from the accident, which has led to instability and potential fishtailing. I am now afraid to drive the vehicle due to unpredictable handling and further mechanical failure. The vehicle is available for inspection upon request. These problems have been confirmed and partially addressed by the dealer when the engine was replaced, but the transmission issues have never been fully resolved. There were no specific warning lamps for the transmission before the failure, but the slipping and erratic gear changes started about one month after purchase and have become progressively worse.

I am submitting this complaint to formally report that my 2017 Lincoln MKZ experienced engine block damage due to a failed torque converter weld, a known safety defect covered under NHTSA Recall 17V-427 / 18V-390 (Ford campaign 17S16). This recall specifically affects vehicles like mine equipped with a 2.0L gas engine and 6-speed automatic transmission, due to improperly welded torque converter studs. This failure causes loss of power and potential transmission or engine damage—precisely what occurred with my vehicle. When I brought my vehicle to an authorized Lincoln dealership in Alexandria, Virginia, the service department refused to cover the cost of repair, despite the vehicle falling within the recall parameters. Their refusal directly contradicts federal recall law (49 U.S. Code § 30120), which mandates that manufacturers and authorized dealers must remedy safety defects at no cost to the vehicle owner, regardless of ownership history or age. As a result of their denial, I am left with significant out-of-pocket costs for damage that should be addressed under a federally mandated safety recall. This poses both a financial burden and a public safety risk if other owners are similarly turned away. I am requesting that NHTSA: Investigate this dealership’s noncompliance with federal recall obligations. Ensure that Ford Motor Company and its authorized dealers are held accountable for safety-related repairs. Assist in compelling the dealer to honor the recall and reimburse or cover the cost of required repairs.

Ford have a Huge problem with the 2.0 ecoboost. Where coolant pass through the cylinder and make engine mix oil and coolant. Ford have a thousand of claim about this and still doesn’t have any solution and they make customer pay everything

While driving the car in commuter traffic on Route 22 Highway the car transmission stopped working and car bucked and then stopped. Upon getting out of the lane of traffic there was a large amount of transmission fluid on the ground. Car had to be towed as it would not move. Danger was the car stopping on the highway in busy traffic. Upon inspection by car dealer they found it had a broken transmission cooler line . The Lincoln dealer put in a Tube Assembly repair kit and replaced all trans cooler lines at a cost of $ 1,029.72 to me. No Warning lamps or messages came on before the lines broke.

The contact owns a 2017 Lincoln MKZ Hybrid. The contact stated that while driving 35 MPH, there was an abnormal sound coming from the engine. No warning light was illuminated. The vehicle was taken to a dealer, where it was diagnosed and determined that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 106,800.

Approximately 2 weeks ago, my 2017 Lincoln MKZ Reserve began sputtering/hesitating during acceleration. On 03/31/2025, I took it to the Heiser Ford-Lincoln in Glendale, WI for service and the diagnosis was I needed to replace my “engine long block” because of engine coolant leaking into the engine cylinders. I was given at an estimated cost of $8,000. I researched and found Technical Service Bulletin 22-2229 listing this issue as a not-so-uncommon problem with Ford’s 2.0 Liter engines. I am highly concerned that this could cause the engine to seize while driving with coolant compromising the viscosity of the engine oil. I firmly believe this should be elevated to a Recall status as this engine is used in several 2017 through 2019 Ford and Lincoln car models - and the occurrence has been frequent enough to have a TSB created.

The contact owns a 2017 Lincoln MKZ. The contact stated that after starting the vehicle, while the vehicle was idling, the vehicle was shaking and vibrating abnormally. Additionally, after shifting to drive, the vehicle erroneously lunged forward, and while shifting into reverse the vehicle jerked backwards. The vehicle was taken to the local dealer who diagnosed that the torque converter and engine were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact was informed that the VIN was not included in NHTSA Campaign Number: 18V390000 (POWER TRAIN). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 100,000.

I have purchased a used 2017 Lincoln MKZ Reserve 2.0l in August of 2023 that started losing coolant and smoking from exhaust. Upon further investigation the coolant was noticed in the cylinder 2 through the spark plug opening. I had changed the head gasket and noticed the slotted coolant journals between the cylinders which was clear this was where the coolant was leaking from. After replacing the cylinder head gasket it run fine for about another month before starting to have same issues of losing coolant and smoking from exhaust, coolant was observed in cylinders 2 and 3. Ford recommended replacing the engine to the new design engine that eliminated the slots, this would be at Customer cost. Engine cost was $2,618.67 in March of 2024 just to purchase the engine, i replaced the engine myself. Vehicle was at 58,735 miles but warranty was out of date.
