When you turn the wheel in your Ford, the torque sensor monitors which way you've turned and how far. Ford describes EPAS with pull-drift as a "sophisticated sensor system that constantly measures the driver's steering torque, adapts to changing road conditions and helps compensate for slight steering changes." But what happens when the system stops measuring? Bad things, that's what. The 2008 Escape (and it's sibling Mariner) were some of the first vehicles to feature Ford's pull-drift steering compensation a part of an all-new EPAS system. Klarry, 2008 Ford Escape Owner from Ashby, MA Power Steering with Pull Drift ∞ Shutting off and re-starting the car seems to HAVE TEMPORARILY solved the problem."
"As with numerous others here, steering froze without warning when driving. Some Ford owners have said that shutting the car off and turning it back on sometimes fixes the issue, although it's only temporary: What's the first question a customer service representative asks you when you call with a tech problem - have you tried unplugging it and plugging it back in? The crazy thing is, that sometimes actually works. Lucy G, 2008 Ford Escape Owner from Elgin, IL I pulled over to closest parking spot, shut the car off and called my husband." It took all my strength to try to turn the wheel to try to get out of the turn and into on coming traffic. "I was driving my 2008 Ford Escape when I made a left turn and my steering wheel froze. But if it's there and then suddenly POOF not there, well that quick and unexpected change is very dangerous: No dash lights, no chimes, just a sudden loss of steering assist.ĭriving a car without power steering is totally possible, I'm sure your grandfather would tell you he did it for years. One major concern about Ford's EPAS is that sometimes when it goes out, it does so without any warning. It's just going to take a lot more effort. There is a mechanical backup, so if the EPAS goes out you'll still be able to steer.

Was it a PSC failure or did the ECU send improper instructions? Perhaps one of the sensors is misreading the data it's supposed to be collecting.įord's EPAS suffers from systemic defects that "render the system prone to sudden and premature failure during ordinary and foreseeable driving situations" and cause drivers of the cars to "experience significantly increased steering effort and, ultimately, loss of control." Ford’s system contains a Power Steering Control (PSC) Motor, Electronic Control Unit (ECU), and a Torque Sensor and Steering Wheel Position Sensor. The systems can, in theory, compensate for things like when the car pulls to one side or drifts.Points 1 and 2 mean your engine can squeeze out a couple extra MPGs.
They have variable power assist, giving more help at lower speeds (when you need it most) but are used less at higher speeds.They are lighter than hydraulic systems.There are perfectly reasonable arguments for making the switch to electronically-controlled steering.
