NHTSA defect investigations
Loss of power steering while driving
Summary
On may 27, 2014, amended june 2, 2014, ford motor company (ford) submitted a defect information report (dir) to NHTSA describing a safety defect that may result in a sudden loss of power steering assist while driving in approximately 746,067 model year (my) 2008 through 2011 ford escape vehicles equipped with electric power assisted steering (NHTSA 14v-284, ford 14s05). Ford's dir described the defect condition as a poor signal to noise ratio [snr] in the torque sensor within the electric power assisted steering (epas) system [which] does not allow the pscm to determine the driver's steering input. When the system detects this fault condition, it transitions the epas system to the fail-safe/

During this investigation, ford identified a condition in subject vehicles equipped with 2.5l and 3.0l engines that may result in a sudden reduction of engine power.according to ford, the etb internal motor contacts may develop a high resistance material buildup condition on the commutator, resulting in intermittent electrical connectivity and reduced engine power. When this condition occurs, the ma
