Steering Wheel Vibrate problems of the 2006 Chevrolet Cobalt

I bought this 2006 checy Cobalt 2 months ago at clear choice auto sales dealership in carlisle and I told them about the steering was rough when I was turning to the right but easier to turn to the left when I took if for a test drive. They took it in there shop and said it was the tire pressure. They then added air to the passengers side front tire then and I noticed that it still was the same when I drive it home. I then found out that I have the 2 recalls for the key and ignition switch so I took it to lawerance Chevrolet and had them replace them and I also had them check on the problem I was having. They said that it was the power steering module column that was the issue but it was going to cost a hole loy of money to replace it. I didnt have the money to get it replace but I knew that there was a recall for the Cobalts steering. I ask them if it was still covered under recall and they said it was already canceled. Idk what to do I really dont want to spend money for this issue when its a recall already and I just bought the call for $5,500. I my steering wheel also shakes when im driving on the highway and when I hit the brakes.

While driving to work, steering wheel had been shaking (55mph). Getting off the belt line, traffic came to a sudden stop. I braked, but the car continued to shake and didn't brake. Had to pull to the side to avoid hitting the car in front of me. Car would not accelerate when traffic started up, and I had to turn the ignition off and restart. Car shook badly for a few seconds, then seemed fine. A few days later, driving into my parking lot (10mph) the car's brakes locked up for no reason and I barely got it into a parking space. Took it in to the dealership the car was purchased at and was told the rotors, brakes, and calipers would need to be replaced. Had another mechanic look at it and had the brakes and rotors replaced. Car drove fine. Six weeks later, driving on the highway (60 mph), slowed down to turn onto another road, and brakes were out. Had another mechanic look at the car, brakes and rotors are worn down again, as well as calipers and brake line. Road conditions were clear at the time of each incident.

I was driving to work,after having the used car for 3 months,when I noticed my steering wheel shaking while I was driving at 60mph. The faster I go,the louder this problem gets. I just purchased 4 new tires in June 2013,had them mounted,balanced and aligned and I still have this shaking problem. When I had a previous problem (with my fuel pump leaking) I noticed many other similar complaints about this shaking (around may 2013) online. I took a trip to michigan for a funeral and had to go back roads instead of interstate due to this severe shaking. Have there been any other complaints sent in? will this become a recall issue as well? please advice.

I purchased my 2006 Cobalt in February of 2007 with mileage of +/- 30000, within the first 2 weeks I had to have the steering column and power steering assist replaced and had to pay for front end alignment caused by the steering a) steering wheel shaking when driving at highway speeds and very violently when breaking and b) the power steering going out. The car now has 107000 miles on it and have had trouble with this same shaking when driving and it being violent when breaking. The dealership states gm is aware but I still have had to redo my front brakes twice (which helps temporarily). . The last time being in June or August of 2013. The shop tells me the problem the first time was the front rotors were sticking and the ground them down smooth. Then the shaking started again. I had to take my car in to have the rotors ground down again and have a serpentine belt replaced. So here I am again 7 months later and will have to do this again because the shaking has started again and is becoming so bad it will have to go to the shop again at my cost for something they know about but will not fix. I have already received a recall letter regarding the ignition problem but am told that the parts are not available and will be informed when they are. This steering/braking problem is serious and I some times fear that either something will break inside the car or I will not be able to hold on to the steering wheel and will wreak. I am afraid to drive my car any distance or speed because I fear it will fail and I see that this has been an ongoing problem since 2007 and people have complained but have received no satisfaction.
