Because of a manufacturing issue, the fuel pump may fail prematurely due to improper nickel plating of certain internal components. If the fuel pump were to fail the engine would stall, increasing the risk of a crash. Dealers will replace the fuel pump on affected models to correct this concern.
The Push-to Start/Stop button may be pushed inadvertently causing the engine and vehicle to turn off unexpectedly and the vehicle to stop, increasing the risk of a crash. If a crash were to occur with the vehicle off the airbags and seatbelt restraints may not function as intended, increasing the risk of injury. Dealers will relocate the Push-to Start/Stop button and reprogram the Powertrain Control Module to correct this concern.
Certain vehicles are being recalled because the upper intermediate steering shaft could separate resulting in loss of steering control. This recall includes models previously recalled under campaign #13V-385, these vehicles may have been incorrectly repaired. Dealers will inspect and replace the upper immediate shaft if necessary. If the steering column lower bearing has separated, a retainer clip will be installed.
The Restraint Control Module (RCM) is the "brains" behind the airbag system. Portions of the module are coated to help prevent moisture intrusion. The coating can crack and when exposed to humidity the printed circuit board may short circuit. This could cause one or more of the airbag system components not to function as expected in the event of a crash, increasing the risk of personal injury. Replacement parts are currently not available, a second notification letter will be sent when they are and dealers will perform the necessary repairs.
In the affected vehicles, the halfshaft retention clip may not have been properly installed. As a result, without prior warning the halfshaft may move outward and disengage from the linkshaft while driving. This would result in loss of engine power to the drive wheels. Dealers will inspect the vehicles to make sure that the halfshaft is properly retained. If it is not, dealers will replace the linkshaft and also replace the halfshaft if it shows evidence of spline damage.
The recliner mechanism for one or both front seats may have been improperly welded to the seat frame. As a result, the seatback may become loose or lean, increasing the risk of injury in the event of certain types of crashes. Dealers will replace the affected seatbacks to correct this concern.
All late model vehicles with an automatic transmission have been designed so the shifter cannot be moved out of the park position unless the brake pedal is depressed. Certain MKZ vehicles are being recalled because the transmission range sensor may not function correctly, allowing the transmission to be shifted out of park without fist applying the brake pedal. This could cause the vehicle to roll unexpectedly, increasing the risk of a crash. Dealers will update the Powertrain Control Module (PCM) software to correct this concern.
The intermediate shafts connect the steering column to the steering gear. Vehicles in areas where salt is used to de-ice the roads are being recalled because severe corrosion can damage the lower intermediate steering shaft. This can cause the upper intermediate shaft to collapse and separate at the lower steering column bearing. Separation will result in complete loss of steering ability. Dealers will replace the lower intermediate steering shaft and inspect the upper intermediate shaft and steering column lower bearing for damage, they will be repaired or replaced as necessary. If the steering column lower bearing has separated, a retainer clip will be installed.
Additionally, Vehicle owners located where salt is not used who have concerns regarding their steering will have a one-time option to have their vehicles inspected and, if necessary, repaired.
The rear doors on these vehicles are equipped with child safety locks that prevent the doors from being opened from the inside when engaged. As the rear doors are opened and closed, one or both child safety locks may switch from engaged to disengaged without warning. With the child lock disengaged, a door could be opened accidentally, increasing the risk of injury to an unrestrained occupant. Dealers will test the safety locks and replace those not meeting the testing standard.
The fuel delivery module, which is located at the fuel tank, can crack, resulting in a fuel leak. Any fuel leak always increases the risk of a fire. Dealers will replace the fuel delivery module in the affected vehicles to correct this concern.
