Lincoln MKZ ProblemsHarsh or Delayed Shifting of Automatic Transmission
The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.
A coolant leak may develop from the heater core. The failure may be due to electrolysis. Our technicians recommend to check for voltage in the coolant with the battery disconnected. If voltage is found the cooling system should be flushed and jumper wires added to engine ground straps as necessary.
The power steering may leak fluid at the pump, hose, or steering gear. This can be caused by one or more hoses not being clamped tightly enough. The repair involves adding new clamps and seals to the power steering hoses at the pump and steering gear.

Lincoln MKZ RecallsPassenger Frontal Air Bag Inflator Ruptures On Deployment
The passenger frontal air bag inflator may rupture on deployment, causing metal fragments to come through the air bag and injure occupants. Dealers will replace the passenger frontal air bag inflator free of charge to resolve the concern.
The steering motor sensor may fail, resulting in loss of power steering assist from the electric power steering system. Dealers will check the power steering control module (PSCM) for any trouble codes and replace the steering gear for vehicles that have codes relevant to the concern stored. If no codes are found, dealers will update the PSCM software free of charge to resolve the concern.
For vehicles located in cold weather states where road salt and other contaminants may be present on the road, the mounting bolts for the power steering gear motor may corrode and break. As a result the steering gear motor could detach from the steering gear. This would result in a loss of power steering assistance, and make turning the steering wheel more difficult than usual. Dealers will inspect the steering gear motor and replace the steering gear assembly on vehicles where broken or missing attachment bolts are found. If the bolts are intact, dealers will apply sealer to prevent corrosion, and will replace affected bolts as necessary. All repairs will be performed free of charge to resolve the concern.
