If you're experiencing an issue with your 2018 Ford F-150 Diesel Pickup, chances are, you aren't alone. Let's take a look at the 3 most common issues owners have experienced, the most likely causes, and how to fix them.
Owners complain that their F-150 would shift so hard that it would cause a loud bang as if something heavy was in the bed. For some owners, the issue began at 100 miles and others not until 15,000 miles, but the average is about 4,000 miles.
Most Likely Cause: Most owners either stated it was their ECM, while others said the issue was linked back to an air link in the system.
Solution: If it is the ECM, most likely it will need to be reprogrammed to correct the issue. Otherwise, if there is a leak in the system, once the IWE is replaced, the issue should be resolved.
F-150 diesel owners complain of a grinding noise that occurs intermittently during acceleration. For some owners, the issue began around 3,000 miles and for others around 14,000 miles.
Most Likely Cause: This issue is most likely the result of a faulty 4X4 actuator or IWE. This is a very common problem with the 2018 Ford F-150s.
Solution: If it is confirmed that the IWE is bad, this part will need to be replaced. Some owners experienced the same issue again a couple of weeks after repair. Make sure that the technician checks for any other issues which may be causing the IWE to go out.
One of the most common issues according to current owners with the 2018 F-150 is a soft brake pedal that fails to engage properly even when depressed all the way to the floor. The issue occurred in vehicles with extremely low mileage such as 200 miles to over 37,00 miles.
Most Likely Cause: The most likely cause is a defective or worn out master cylinder. When the master cylinder wears out, brake fluid leaks out, which drops hydraulic pressure and leads to a soft brake pedal.
Solution: The master cylinder will need to be replaced and lines checked for any leaks.
