My power steering goes out. if i turn the car off and start it again the steering works fine. doesn't happen every day but happens often and every time i just stop the car and start it again.

fixya doesnt have crystal balls coundnt tell you if it could or would happen or not happen again

did you check the directional switch. sounds like you have a bad one

What is the idling RPM of the engine when this is happening? There are many different types of power steering systems out there these days on vehilcles. It would make it a bit easier if we had a little more information before we give you advice. Year, Make Model, Milage, ect...Any other known issues with vehilce? Yes, the most likely culprit could be the pump because as time goes on the internal pump compoinents start to wear down and the tolerances become to great and at low rmp it cannot keep the proper pressure needed to give adequate power assist to the steering gear.
Hope this helps

could be the pump if your fluid is full, or your belt to the power steering could be slipping..

It sounds like the power steering motor is overheating pre maturely. Changing the motor should take care of the problem. What really happens is the motor reports to the power steering module that it is over heating and the module is shutting power to the motor down, the motor is actually no overheating.

Next time this happens without stopping or pushing gas shift tranny into N and then back into D and see what happens. The battery light came on because of low RPMs, no biggy.

I have a 2006 Accent and also to me sometimes the eps light turn on while I'm driving. I turn off the car and wait few seconds before to turn on again. But how to repair this problem?

This is a known problem with the power steering which will probably require replacement of the power steering motor. The HHR uses an electric 12V DC motor to provide the power steering force, and they have started failing.

GM is recalling the Cobalt and other vehicles for this issue, but not yet the HHR. If you are out of warranty, you will probably be personally responsible for the cost of diagnostics and replacement.

You will probably need to contact your dealer unless you are able to replace the motor yourself. Sorry.

I suspect the ignition switch is malfunctioning.

try changing the coil- sometimes they get hot and break down- once they cool off vehicle will start and run until they get hot again
