Ford replaced hydraulic power steering with an electronic power assisted steering (EPAS) system to improve MPGs and provide variable power assist to owners.
But the EPAS system is subject to electrical failures and premature breakdowns, causing a sudden loss of power steering while driving.
A few recalls have been made, but owners continue to have problems and have filed multiple class-action lawsuits.
Hydraulic systems have a multi-decade track record of successful steering with relatively easy maintenance. So naturally, Ford banished it to the curb and replaced it with something much more complicated.
Be gone, hydraulics! Embrace your digital overlord – electronic power assisted steering (EPAS).
EPAS replaces a lot of the mechanical parts of previous steering assist systems (pumps, fluids, hosts, pulleys) and replaces them with tiny computers called ECUs and a whole bunch of code.
Ford'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."
There is a mechanical backup, so if the EPAS goes out you'll still be able to steer. It's just going to take a lot more effort.
One major concern about Ford's EPAS is that sometimes when it goes out, it does so without any warning. No dash lights, no chimes, just a sudden loss of steering assist.
Driving a car without power steering is totally possible, I'm sure your grandfather would tell you he did it for years. But if it's there and then suddenly POOF not there, well that quick and unexpected change is very dangerous:
"I was driving my 2008 Ford Escape when I made a left turn and my steering wheel froze. 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 pulled over to closest parking spot, shut the car off and called my husband." Lucy G, 2008 Ford Escape Owner from Elgin, IL
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. Some Ford owners have said that shutting the car off and turning it back on sometimes fixes the issue, although it's only temporary:
"As with numerous others here, steering froze without warning when driving. Shutting off and re-starting the car seems to HAVE TEMPORARILY solved the problem." klarry, 2008 Ford Escape Owner from Ashby, MA
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. 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.
When you turn the wheel in your Ford, the torque sensor monitors which way you've turned and how far. That information is sent to the ECU, but what happens when the information never gets sent? One widely accepted theory is that a defective torque sensor isn't giving the ECU the information it needs, and the power steering as a result gets disabled.
So the simplest solution is to just replace the torque sensor, right? Well, unfortunately the torque sensor is part of the steering column assembly and is not serviceable separately. In other words, once that sensor goes the entire steering column needs to be replaced. And that's expensive with the average repair cost around $1,500.
Ford and Mercury Vehicles Most Likely to Lose Power Steering ∞
Consumers slapped Ford with a class-action lawsuit in a California district court, claiming Ford equipped the Focus and Fusion models with a defective power steering system that is prone to sudden failure.
The official complaint says Ford "failed and continues to fail to disclose to consumers that the defective steering system exposes occupants of the defective cars, occupants of the surrounding vehicles, and pedestrians to the "risk of collisions and grave bodily harm."
The complaint also says "Ford has ignored, concealed and failed to adequately address the numerous complaints it has received about defective vehicles' steering failures" and that "Ford’s knowledge of problems with the EPAS system in the defective vehicles was revealed during the course of a NHTSA investigation into steering failures experienced by the Ford Explorer, which suffers from a similarly defective EPAS system.”
The plaintiffs accuse Ford of falsely touting the safety and reliability of the defective autos at the same time the company promoted the vehicles as safe and by lauding the Electronic Power Assisted Steering (EPAS) specifically, states the complaint filed June 27 in the U.S. District Court for the Northern District of California in San Jose.
Plaintiffs William Phillips and four other individuals from various states and North Carolina-based Performance Fire Protection LLC claim Ford made misleading and reckless public statements about the general safety ratings for defective cars, the suit claims.
May 2014: Over 900,000 2008-2011 Ford Escape and Mercury Mariner SUVs were recalled because of failures with the torque sensor inside the EPAS. Additionally, the 2011-2013 Explorer was recalled because EPAS electrical connection failures. Roughly a year later the National Highway Traffic Safety Administration (NHTSA) was petitioned to see if that recall really did any good.
April 2015: 520,000 model year 2013-2015 Ford Fusion and Lincoln MKZ, plus 2015 Ford Edge CUVs were recalled because their steering gear bolts can corrode and break, causing an immediate loss of power steering.
Lawsuits about this problem have already been filed in court. Many times these are class-action suits that look to cover a group of owners in a particular area. Click on the lawsuit for more information and to see if you're eligible to receive any potential settlements.
A Ford Focus and Fusion electronic power assisted steering (EPAS) lawsuit won't be certified as a class-action after a judge ruled the plaintiffs can't prove all owners experienced harm from the alleged defect.
Ford filed a motion to dismiss the lawsuit and U.S. District Judge Lucy H. Koh agreed to do just that. Ruling the power steering lawsuit is unwieldy in scope and unduly burdensome, Koh gave the plaintiffs a 30-day deadline to amend the complaint or face dismissal with prejudice of Plaintiffs’ claims.
The plaintiffs claim the power steering system is advertised with a feature that helps drivers with pulling and drifting based on road conditions. The system is supposed to work automatically, but the lawsuit alleges the system fails on the road, causing a problem with turning the wheel.
Generations Where This Problem Has Been Reported
This problem has popped up in the following Ford generations.
Most years within a generation share the same parts and manufacturing process. You can also expect them to share the same problems. So while it may not be a problem in every year yet, it's worth looking out for.

Power steering is one of those things you don't think about until it's gone.
The lawsuit didn't even cover all the models or years affected by this problem. And now that it's going away, the complaints seem to be picking up as more cars exit their warranty period (because life is fun like that).
And oh, by the way, an out-of-warranty repair costs about $2,000.
Ford is doing its best to steer clear of an EPAS lawsuit
, saying the plaintiff's claims don't merit class-action certification because the steering problems are too widespread to prove any "common defect." Nothing says confidence in your product like saying there's too many defects to prove one, singular defect.
"In addition to denying the electromechanical relays are defective, Ford says the claims should be dismissed because the alleged defects, if they exist, occurred during manufacturing at different times and with different models. Due to this, the plaintiffs cannot claim a "common defect" is associated with the Focus and Fusion cars."…
