Lincoln MKZ motor vibration felt throughout the car at standstill and while driving, persists after replacing number 3 coil and all spark plugs on Lincoln MKZ

Some Lincoln MKZ owners report experiencing persistent motor vibrations that are felt throughout the vehicle, both at standstill and while driving, even after replacing the number 3 coil and all spark plugs. These vibrations can be attributed to several potential causes, including unbalanced wheels, particularly affecting the front, which can lead to noticeable vibrations. Additionally, a bad motor mount may contribute to these vibrations during acceleration and deceleration, as it connects the motor to the chassis and absorbs vibrations. Some owners also report that vibration under acceleration may indicate issues with the CV joints, especially if there were previous noises from the front wheel bearings. Problems within the steering system, shocks, tie rods, or alignment could also be responsible for the vibrations, necessitating inspection by a mechanic. Furthermore, some owners note that driveline sensations, such as shuddering during tight turns or light acceleration, may require attention. A comprehensive inspection by a qualified mechanic is recommended to accurately diagnose the cause of these vibrations.
