  1. Most lug nuts are one piece of hardened steel, but Ford chose a design that puts an aluminum cap over a steel core.

    The cap is notorious for swelling and delaminating when it gets hot. It’s also a great place to trap moisture and encourage corrosion. The end result? A lug nut that’s either too big for a standard wrench or fused so tight you need a drill, welding torch, and 7 Hail Marys to remove it.

    A 2017 class-action lawsuit accused Ford of cost-cutting when switching to the two-piece design. It also said the automaker is aware of the problems, but won’t honor its warranty by denying any lug nut related claims.…

  2. Ford has issued a small but important electrical recall for 87 vehicles with improperly secured power supply cables.

    The cables are at the starters and alternators and the unsecured connections could cause electrical arcs. Those arcs could easily start fires.

    There are so many recalls these days that it’s no longer shocking when brand new vehicles get called back for repairs. But it really makes you wonder wire these automakers can’t get their act together.

    Puns aside, find out if your vehicle is affected here. It only takes a minute, so watt are you waiting for?

  3. Ford wants the lug nut lawsuit tossed because "the plaintiffs never allege the swollen lug nuts have ever caused physical injuries to any person or damage to any property."

    Ford also says the plaintiffs talk about swollen lug nuts as if the lug nuts should be indestructible and the warranties should last forever, then wrongly "attempt to cast their product-defect allegations as warranty, fraud and unjust-enrichment claims."

    Should lug nuts last forever? Of course not. But they also shouldn't fuse into something harder than a diamond after 10,000 miles on the road.…

  4. Ford has been sued for switching to a 2-piece lug nut design that features an aluminum cap.

    When exposed to the elements, the cap swells in the heat, cracks and delaminates, and corrodes from moisture. This leaves owners and lessees who get flat tires often stranded on the roads without the ability for even tow truck drivers to remove the swollen lug nuts. This means a tow to the shop just to have the lug nuts removed and the tire replaced.

    The two-piece capped lug nuts are cheaper than a one-piece stainless plug, but they look nice because of the cap. Most owners never think twice about the lug nut when buying a vehicle, only to be met with this headache down the road.

  5. Busted modules are telling the fuel pumps in 88,000 Ford vehicles to take the day off.

    It should come as no surprise that those modules need to be replaced before those vehicles stall out.

    "Recalled are the 2013-2015 Ford Taurus, Ford Flex, Lincoln MKS, Lincoln MKT vehicles equipped with 3.5-liter gasoline turbocharged direct injection engines. Also included are 2013-2015 Ford Police Interceptors with all engine types."

    There are limited details on when the recall will begin, however build dates of the affected vehicles have been released.
