Ford is once again calling on model-year 2021-22 Ford F-150s to be brought in for service over concerns with a fractured driveshaft — but if this sounds familiar, note a subtle difference: This population of pickup trucks were not initially supposed to have underbody heat and noise insulators.
More than 58,200 of the latest-gen F-150s are affected. The footnote of difference between these trucks and the 185,000-odd pickups included in the December recall comes down to what the National Highway Traffic Safety Administration reports as a potential error: The latest recall includes trucks that were “neither designed nor intended to be built” with underbody insulators, thereby excluding them from the previous recall. However, a Ford spokesperson clarified in an email to Cars.com that such F-150s are only expected to be 3% of this recall’s overall population.
Ultimately, underbody sound insulators may have been installed with inadequate adhesion, resulting in loose or sagging insulators that could damage the driveshaft to the point of fracture, causing a loss of drive power or control. Additionally, unintended movement could occur while parked if the parking brake isn’t engaged. Each of these scenarios increases the risk of a crash.
To resolve the problem, dealers will inspect and repair the driveshaft, as necessary. They will also properly attach the underbody insulators. Both repairs will be done for free, and owners will be notified starting Sept. 5. Those with further questions can call the automaker at 866-436-7332 (Ford’s number for this recall is 21S53) , the NHTSA’s vehicle-safety hotline at 888-327-4236 or visit its website to check your vehicle identification number and learn more.
