Ford Motor Company has issued new safety recalls for five of its vehicles, including three of its trucks, and expanded an existing recall of three vehicles, including the Edge compact SUV, according to Ford.

In the first new recall, the automaker is recalling an estimated 7,500 2018 Ford F-150, Expedition and Lincoln Navigator vehicles equipped with a 3.5-liter GTDI V-6 engine because the high-pressure fuel pumps may have misaligned welds.

The fuel pump assembly may have inadequate welds between the pump housing and its mounting flange, making the welds vulnerable to high-cycle fatigue fractures that could cause the fuel pump to move relative to its mounting flange, according to Ford. This scenario can lead to the loss of the sealing integrity of the cam cover or the fuel lines and an oil or fuel leak, increasing the risk of a fire.

To fix the problem, Ford dealers will replace the high-pressure fuel pump, high-pressure fuel discharge tube, and high-pressure pump and discharge tube mounting bolts at no cost to vehicle owners. Ford is not aware of any fires, accidents, or injuries related to this problem.

Vehicles affected by this recall include:

• 2018 Ford F-150 vehicles built at Dearborn Truck Plant between March 14 and April 24, 2018

• 2018 Ford F-150 vehicles built at Kansas City Assembly Plant between March 20 and April 17, 2018

• 2018 Ford Expedition vehicles built at Kentucky Truck Plant between March 14 and April 12, 2018

• 2018 Lincoln Navigator vehicles built at Kentucky Truck Plant between Feb. 20 and May 6, 2018

The recall involves approximately 5,645 vehicles in the United States and federalized territories, 1,625 in Canada and 310 in Mexico. Ford’s reference number for this recall is 18S17.

F-650/F-750 Recall: Hydraulic Brake Systems

Ford is also recalling approximately 1,500 2018 Ford F-650 and F-750 vehicles with hydraulic brake systems because they may not have received the specified anti-corrosion protection plating on the brake hose assemblies. Inappropriate anti-corrosion plating can potentially lead to premature corrosion of the brake hose ferrules, which, in turn, can cause brake fluid leakage and reduced brake function, which increases the likelihood of a crash.

To remedy the problem, dealers will replace the brake hose assembly with parts that contain properly plated ferrules at no charge to owners. Ford is not aware of any fires, accidents, or injuries related to this problem.

Vehicles affected by this recall include 2018 Ford F-650 and F-750 vehicles built at Ohio Assembly Plant between Jan. 26 and March 13, 2018.

The recall involves approximately 1,474 vehicles in the United States and 11 in Canada. Ford’s reference number for this recall is 18S19.

Expanded Recall for Edge, Fusion

Ford has also announced that it is adding 27 2018 Ford Edge, 2018 Ford Fusion and 2017 Lincoln MKZ vehicles to an existing safety recall for Ford Edge, Fusion and Lincoln MKZ vehicles equipped with a 2.0-liter gas engine and 6F35 transmissions in North America because they may have torque converters with inadequately welded studs.

With this scenario, the studs can potentially detach in which case the torque converter will lose coupling to the engine flexplate. This, in turn, can lead to loss of motive power without warning while the vehicle is being operated, which may increase the chance of a crash.

To fix the problem, dealers will replace the torque converters at no cost to the customer. The automotive manufacturer is not aware of any accidents or injuries related to this problem.

Affected vehicles include:

• 2017 Ford Edge vehicles built at Oakville Assembly Plant between April 25 and July 28, 2017

• 2018 Ford Edge vehicles built at Oakville Assembly Plant between Oct. 10 and March 8, 2018

• 2017 Ford Fusion vehicles built at Hermosillo Assembly Plant between May 4 and June 15, 2017

• 2018 Ford Fusion vehicles built at Hermosillo Assembly Plant on Aug. 24, 2017

• 2017 Lincoln MKZ vehicles built at Hermosillo Assembly Plant between May 4 and Aug. 24, 2017

The recall now involves approximately 6,063 vehicles in North America, including 5,352 in the U.S. and federalized territories, 699 in Canada and 12 in Mexico.
