A major recall is affecting a few vehicles in the Ford family, including the F-Series pickup trucks, as well as the Expedition and Navigator (Lincoln) SUVs of the 2020 and 2021 model years. The problem is related to the wiper system which can cause the wipers to malfunction.
Obviously, a wiper that is no longer present during difficult road conditions can lead to a significant loss of visibility and, at the same time, increase the risk of an accident.
According to Ford, one of its suppliers used worn assembly tools that resulted in wiper arms with longitudinal moldings (rods) that are not high enough to fully engage the engine pivots they are mounted on. This can cause them to come off when the motors are turned on. As a result, the wiper arms may not move at all or may only engage intermittently.
"This can cause the arm attachment to become detached when used with certain high-torque wiper motors," Ford said in its defect report submitted to the National Highway Traffic Safety Administration (NHTSA). "Potential symptoms include erratic or slow speed of either wiper arm."
