There are 3 owner-reported engine complaints for the 2019 Lincoln MKZin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Vehicle model is prone to coolant intrusion which causes misfire and engine shut off while driving. Car shakes while accelerating.
Technical Service Bulletin 19-2387 My vehicle has this defect which is an ongoing problem and at the time of this correspondence my vehicle has under 13,000 miles. Seepage around the perimeter of the oil pan which in time will result in a steady leak and in turn loosing enough oil will cause engine damage. Technicians refer to this as the oil pan sweating. As per the Technical Service Bulletin this problem exists on 2017 to 2019 Lincoln MKZ 3.0 which Ford installed a plastic oil pan on all new vehicles to reduce the weight of the vehicle. The 2017 to 2019 Lincoln MKZ 2.0 were fitted with metal oil pans and there is no issue. I notified Lincoln customer service and they are aware of this problem yet a recall has not been issued. This is a manufacturer defect and Ford should take responsibility to correct this problem. A recall should be issued. Thank You for your attention on this matter.
