Lincoln MKZ ignition coil failure and major oil leaks resolved with gasket and ECM replacement on Lincoln MKZ

Some Lincoln MKZ owners report experiencing ignition coil failure, which often requires complete replacement as faulty coils cannot be repaired. Symptoms of this issue may include difficulty starting the engine, engine misfires, and check engine light warnings. Additionally, some owners note that ignition coil failure can stem from bad coil packs or wiring harness problems. Furthermore, some Lincoln MKZ owners report dealing with major oil leaks, commonly caused by worn-out drain plugs, damaged gaskets, or oil system component failures. In cases where damaged gaskets are identified as the source, replacing them can effectively resolve the leaks. Regular maintenance checks are recommended to catch and address oil leaks promptly to prevent further engine damage. Additionally, some owners may face issues with the engine control module (ECM) not providing readings to new coils, which can lead to performance problems, necessitating ECM replacement. For those uncertain about diagnosing or repairing these issues, seeking professional assistance from a mechanic or dealership is advisable.
