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.
Vehicles sold in cold weather climates may be equipped with an engine block heater. A block heater plugs into a standard home electrical outlet and is used to keep the engine block from freezing in extremely cold temperatures. 107 2013 Lincoln MKZ models are being recalled the electrical cord to the block heater can crack, exposing the wires, and increasing the risk of electric shock. Dealers will replace the block heater cord to correct this concern.
During the manufacturing process, the side seam of the fuel tank may not have been properly sealed and as a result, the fuel tank would be weakened and not perform as expected in the event of a crash. In addition, a fuel leak could develop at any time. Dealers will inspect the fuel tank and replace it as necessary on vehicles included in this recall.
Certain vehicles may have been assembled with a transmission range sensor (TRS) that was calibrated out of specification for reverse gear. If this condition exists, the transmission may not properly engage reverse gear and/or if reverse gear does engage, the "R" indicator on the dash or the backup lamps may not illuminate. These conditions increase the risk of a crash or a pedestrian being struck due to the vehicle's not signaling it is in reverse. Dealers will inspect and replace the transmission range sensor as necessary to correct this concern. The Ford recall number is 12C23.
These vehicles may have inadequate welds on the head restraint support brackets for the second row, right side seat. In the event of a crash, the head restraint may not provide adequate protection, increasing the risk of personal injury. Dealers will replace the head restraints as necessary to correct this concern. The Ford recall number is 12C22.
