Anytime while driving, the power steering will flash on my dash and my car will start to jerk aggressively. If I can't pull over and I drive for just a while to find somewhere to pull over, my car will stop moving and start going backwards in the middle of the street. I had an o2 sensor replaced which stopped the power steering to go out for a while but it started back again. My power steering will also go out as I start the car, forcing me to turn the car, wait a few seconds and start it again. It can go on for a while and multiple mechanics have looked at the car because the check engine light comes on but they can't see anything wrong with it. I have to wait 30 seconds before I can drive my car, which can make me late to places if I have to do it multiple times, if I don't wait then the power steering will go out on me and it can happen anywhere. Last year, it went out while I was going 60mph on the highway and I couldn't go anywhere to pull over, I'm lucky I didn't cause an accident.

The traction control system light on my chevrolet cobalt 2005 stays on and does not turn off until I shut off the engine. The check engine light also stays on as well at the same time the traction control system light is on, so not sure if these two issues are related. I also notice that the vehicle jerks periodically when I am on the road and there is rough shifting of gears.
