Power steering warning came on?

Tried to use wipers this morning, warning light came on that said "power steering" then wipers wouldn't work. Drove it to work, came out after work and wipers worked and the warning wasn't showing anymore. I'd like to know what it could possibly be. There is no whining noise when i turn the wheels to indicate anything is wrong with my steering. I am aware now that Chevy Cobalts have electric steering and do not take power steering fluid.

My car has 135000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there, thanks for writing in. I’d be happy to provide my insight. This is a common issue in the Chevy Cobalt. The electrical system on modern cars is very sensitive and everything needs to be working nearly perfect in order for the check engine lights not to come on and this includes even having a strong battery. I would recommend having the battery tested as even a weak battery can cause issues like this. I would also recommend having the car computer scanned at the same time to see if any trouble codes show up which may indicate potential problems elsewhere.

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.

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.

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.

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.
