Ford Super Duty Problems Arise via Rear Axle Recall, Defective Fuel Pump Lawsuit

2023 Ford Super Duty F-350 Limited

Between defective fuel pumps that can destroy an engine and a new recall, Ford Super Duty owners have several things to look out for.

It’s not exactly a secret that Ford Motor Company has faced it fair share of quality problems over the past couple of years, many of which have become quite high-profile after the automaker finished 2022 as the most recalled manufacturer in the business. Among its many recalls and other mishaps, The Blue Oval has issued plenty pertaining to the F-Series line of trucks, which is the best-selling model in America and has been for a very long time. The Ford Super Duty isn’t immune to this phenomenon either, and now, owners are being hit with a couple of alarming pieces of news pertaining to the truck’s defective fuel pumps and rear axles.

First up, the brand new, redesigned 2023 Ford Super Duty – which just launched earlier this year – has been hit with a couple of recalls thus far, with the latest pertaining to the left rear axle shaft. This issue doesn’t effect all 2023 model year pickups, however, but just F-250 and F-350 models that are equipped with single rear wheels and a 10.5-inch rear axle shaft, and were produced between March 20 and August 21, 2023 – around 41,555 total vehicles.

In those models, the left rear axle shaft may have been improperly heat-treated while it was being manufactured, which could cause it to break – not a terribly good thing, obviously, as that could cause the pickup to roll away or lose power, which could increase the risk of a crash – though to Ford’s knowledge, that hasn’t yet been the case.

On top of this, many Ford Super Duty owners whose trucks are equipped with the 6.7-liter Power Stroke have also long complained about the high-pressure Bosch CP4 fuel pumps used in these diesel-powered vehicles from 2011 onward. Now, a new lawsuit has been filed in Michigan over this particular problem – David Clark v. Ford Motor Company – according to Car Complaints.

As is the case with prior complaints, this lawsuit claims that the CP4 fuel pumps are defective and contain metal parts that rub against each other, which eventually causes metal shavings to enter the fuel system. This is obviously disastrous, and can eventually destroy not only the fuel system, but also the engine itself – leading to some pretty costly repairs. Making matters worse, the lawsuit also claims that U.S. diesel fuel doesn’t have enough lubrication to compensate, which means that the cam and rollers wear down and eventually introduce their own metal shavings into the engine as well.

The plaintiff in this case – David Clark – claims that this is precisely what happened to his 2020 Super Duty when it had just 23k miles on the clock, as it went into limp mode and then stalled out, which prompted him to take it to the dealership. There, he was told that his warranty claim was being rejected, and that he had to pony up the $12k needed to repair the pickup. Given the fact that this isn’t the first time someone has claimed that the CP4 fuel pump is defective, it doesn’t seem like an isolated case by any measure, and is certainly something that owners should be on the lookout for.
