What owners say
The cobalt brakes have always made a screeching sound, which gm has addressed as being normal. Chevrolet #08-05-22-004: information on brake squeal/squeak noise - (jul 15, 2008)] however, I had to prematurely replace the rear brakes and have the rotors cut after only 27,039 miles, while the front brakes still had 50% life left. This is not a normal occurrence, since the front brakes should have worn out before the rear ones. While I was able to get 27,039 miles of wear, the fact that there is definitely a defect in the system means there is no guarantee that the condition will not worsen in time. There is also the chance that the system could fail completely causing a serious accident. Finally, the screeching sound is getting worse. This sound, along with the brake wear, will virtually reduce the value of the car considerably, making it nearly impossible to trade or sell, unless gm corrects this issue.
Bought my cobalt ss new from dealer, with less then 5,000 miles rear brakes were squealing and very obnoxious. Upon inspecting and bringing the car to the dealership was told that my brakes had gouges in them and needed to be refinished and cleaned as well as new pads installed. This was not covered under the warranty as they said it was wear and tear and the noise was normal.
Rear brake rotors have massive gouges causing a grinding noise.
1. Begin squeaking and e brake begins to no longer hold the car 2. Rear breaks pads wear out very quickly about every 10,000 to 15,000 miles 3. Put new pads on.
Purchased the car new. At about 3,000 miles I noticed scoring on the rear brake rotors. After about 12,000 miles my emergency brake started failing to hold the car on even the slightest hill. At about 14,000 miles the rear brakes started to grind. At this point the brake pads needed to be replaced, and the rotors turned. Only the inside pads were worn completely down, the outside pads looked relatively good.
Brakes started squealing a few months after buying the car brand new. Now, about 1.5 years later, they are grinding an excessive amount and their performance has extremely decreased. I fear I will have to change entire rotors and pads to fix this problem out of my own pocket within the next month on good aftermarket parts since the factory can't produce good quality oem parts and general motors doesn't give a flying ****. I informed my local dealer of the problem and they shrugged me off, but only after wanting to charge me $60 to just look at them. I shouldn't have to pay for them to inspect brakes that are faulty in under 2 years, and 20,000 miles; and I also have an extended warranty that I paid for. Apparently, it's just mainly the rear brakes that are the issue with these cars, but every owner I know, who hasn't already replaced the brakes with aftermarket performance parts, have the exact same issue, and in some cases, much worse. If the brakes fail within the next month or two and an accident happens(quite possible since rust is appearing on one of my rear rims due to the rotors being scoured so excessively, I fear one of them may let go and snap completely off)before either a recall, or I put aftermarket products on, gm will be facing a lawsuit by yours truly; especially if serious injury occurs.
Rear brakes on a 2009 cobalt ss turbo score and grind within 10,000 miles. You have to put after market brakes on the car.
My rear brakes on my 09 cobalt ss are wearing unevenly. My right side rear brake pads are completely used up and as a result have begun to grind on to the rotors and caused them to form pits, and or grooves. Very disappointing.
Bought my 09 cobalt ss tc sedan with 3500 miles on it. Rear rotors already had grooves at that mileage. My car is at 8700 miles now with both rear brake calipers having to be replaced along with deeper grooves in rear rotors and squeaking from the rear brakes. The failing rear brakes caused my emergency brake to fail. The emergency brake failed while on a hill and I walk outside to find my car under my girlfriends truck! (e-brake engaged and in reverse) this was fixed with the calipers being replaced, I still need to have my rotors worked as they are already to this point. I was fortunate to be parked on a not so steep of a hill, couldn't imagine someone in the same situation living in a hilly region. (lawsuit waiting to happen).
