Experienced mechanics share their insights in answering this question :
Hello, thank you for writing in. When you have a warning light like this on, it may be sensor related, or it may be mechanical. The power steering system is electric, and there are not many tests you can do on the system without manufacture specific tools and software. It may be a software issue pertaining to draining the battery, as other Fords around this year have experienced similar issues. If you lifted the vehicle wrong, you may have damaged the rack, which is the main component driven by its own motor to assist with steering. You can perform a visual inspection to make sure nothing looks damaged, but beyond that, there is little you can do with this type of higher tech power steering system. One question that needs to be answered is if the vehicle is having any issues driving. If it is steering normally, starting normally, and showing no other signs of issues, clear the code and see if it comes back on. If it does, you should have the system inspected by a professional. Unfortunately when there is an issue with the electric power steering systems, the main repair is to replace the entire rack and pinion.

can i temporally get power steering back from a power steering assist fault in a 2011 ford fusion. want to trade in and not fix
ANSWER : Hi there. The Power Steering system on your Ford Fusion includes both the normal hydraulic system used for many years now to make steering your car easier, as well as a Power Steering Assist system that augments the regular power steering. If a problem develops with the Power Steering Assist system, it will be deactivated. You’ll see a warning in the message center that reads “Power steering assist fault.” In order to resolve this issue, a warning light inspection would have to be completed to clear the code. However, if an actual fault exists in the system, it would re-trigger the warning light. Since this is a common problem with Fusions, repairing or not repairing the warning light would not impact the trade in value in most cases.

power steering fluid is leaking
ANSWER : With a power steering fluid leak that big, you certainly should have the vehicle inspected as soon as possible to find the exact cause. Any of the components you listed can be the source of the leak. The power steering pump as well as the rack & pinion steering unit rely on the fluid for lubrication as well as cooling. The whining you hear is from the pump when the fluid runs low or empty. Your issue can be caused by something as simple as a fluid hose right now, but continued ’running dry" of the power steering fluid, can result in damage to both the pump and the rack & pinion unit. If that happens, you can take what may be a repair of a few hundred dollars and turn it into a repair of a couple of thousand dollars.

Very loud pop when turning sharp left leaking transmission or power steering fluid where steering column meet rack
ANSWER : Hi there. If everything else has already been installed from the donor vehicle then it sounds like the high pressure hose is all that you need to install. The hardest part of doing this is the routing. One thing you may also want to double check is that the donor vehicle and your 2003 Escape have the same rack. There are different models depending on the model and the size of your wheels. You need to install the pressure line first, but if it does not line up then you may have the wrong rack installed.

had power steering pump replaced but power steering fluid is leaking
ANSWER : This suggests that you may have a leak somewhere else in your power steering system such as one of the hoses or the rack and pinion system. As you may know, the power steering system is a highly pressurized system that can have as much as 300+psi of pressure in the system at times, so it is not uncommon for these types of leaks to happen. If you’d like to get this fixed, I would recommend having an expert from YourMechanic come to your location to diagnose the leak in your power steering system and make the the necessary repairs to fix it.

2011 Fusion power steering assist fault and service advancetrac at same time. restarted w/ no reset. drove 50mi w/ no steering wtf
ANSWER : Hello. The issue may not be incredibly complex or major. With newer vehicles being equipped with more complex diagnostic systems, it is not uncommon for one issue being related to two separate warning lights. The first step is to have the vehicle scanned for diagnostic codes. This can be done at most automotive parts stores or by a technician. Once you have that information you can make repairs or continue testing. Your vehicle in particular has a large number of sensors, one of which may need to be replaced. The repairs needed may be more complicated but there is no way to know until the codes have been scanned. For more help with diagnostics and repairs, contact our service department to schedule an appointment.

Steering wheel shakes, light came on power steering assist failure 2010 Ford Escape
ANSWER : Hi there – this behavior, sometimes called "phantom steering shake" is often due to a steering torque sensor in the steering column. This device sense how much effort is being put into the steering wheel to make a turn. This determines how much "power assist" the electronic steering adds to your own effort to turn the steering wheel. If you are getting the "shake" while idling and still, this can be the beginnings of failure of this sensor. I would first go back to Ford to discuss the Recall (#14V284000), because this appears to be precisely the problem you are having. Escalate to Ford Customer Service. If this is unsuccessful, I recommend a steering wheel shakes inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs.
