I have an extreme vibration and some clanking noise in the front end of my 2007 Chevy Cobalt whenever applying my brakes on a downhill slope. I do mostly freeway driving and fortunately there aren't a lot of hills, so my brakes are not under much stop and go strain. I was told the my control arms and bushings will have to be replaced and that it may cost $900 or more after labor. Due to the cost, I have not been able to do the repairs and after looking online, I see that several other people have had the same issue and replaced these parts only to find they need to be replaced again in as little as a year. My last Chevy had nearly 300,000 miles on it and there was never an issue with the control arms, so this definitely should not be happening.

The traction control light has turned on several times before but usually goes away. While hitting my brakes on the freeway to exit, my traction control light turned on today. I was going about 60 and slowing when it happened. The vehicle jerked violently causing me to slam forward in my chair and almost causing the person behind me to hit me. Once I stopped at the light and hit the accelerator again, it again jerked. I parked my car and shut it off. I turned it back on and put it into drive and immediately the car jolts. It continues to do this each time I switch from park to drive and from braking to driving.

I had to get my rear brakes completely changed out at around 45000 miles as well as my E-brake assembly. Apparently Cobalt rear brakes are known to wear extremely quickly, please recall everything that was replaced: Rotors calipers pads E-brake assembly brake lines.
