Brake Disc Pads problems of the 2009 Chevrolet Cobalt - part 2

Brake pads wear at an extraordinary rate. They have also gouged the rotors. This is on a brand new 2009 chevy Cobalt ss, less than 9000 miles on the car (purchased in April). The brakes continually squeak, and have done so since I picked up the car. The dealership explained it was a "break-in" period, but clearly it shouldn't last this long. The squealing, in addition to being annoying, may pose a safety risk due to the accelerated pace at which they brake system wears. I noticed after a car/wheel wash, the noise dissipates, but returns soon thereafter. I'm concerned about the longevity of the brake system.

Rear brakes having pre mature wear of the inner pads and severe gouging of the rotors. Outer pad was 75% worn and inner pad was 98% worn at 10k miles.

1. Car is a daily driver, so no abuse or anything. 2. Rear brakes are squealing again after being replaced once (pads and rotors replaced by dealership) 3. The rotors and pads have been replaced once, but it's happening again.

I have a 09ss/tc and I have a problem with my back rotors with lines and grooves in them. I only have 4000 miles on my car now. I took it to the dealership at 3500 and the shop manager argued with me that it is normal wear and tear and that the back brakes are "aggressive" style pads. And he argued that the back do more stopping power than the front. They haven't done anything about this problem yet and I know that many other cars of the same model have this problem. The main mechanic did confirm that it isn't a normal wear but said that the car is too new to anything about it. Please help us out I really don't want this to cause an accident or for me to have to pay for all new rotors and pads at my expense because of their mess up.

Rear brakes and rotors exhibit excessive wear. Rotors grooved and pads worn on inside of rotors only. Finally had rotors and pads replaced @ 19,800 miles.

Wearing of rear brakes. This includes deep scoring of the rotor and brake pad as well as loud grinding when stopping. This has been ongoing since 100 miles. I am now at 5k miles and have seen a few cars with the same problem. Pads and rotors need to be replaced and an alignment done.

My rear brakes on my 2009 Cobalt ss with just over 17000 miles on it were completely gone when I took the car to the dealership on Tuesday July 28th of 2009. I first noticed some unusual noise coming from the rear of the vehicle at around 15000 miles. At first the noise was sporadic and I was not concerned with it but it soon developed into a constant friction type noise that could not be ignored. After leaving the vehicle with the dealership all day they found the cause of the problem. My rear brakes were metal to metal with the rotors. The service employee asked me if I e-brake slide the car, since I was not exactly familiar with the term he had to clarify its meaning. I told him I am not an e-brake sliding kind of guy and asked him to check the ware on the tires if he did not believe me because it sounds like performing a maneuver like that would cause the tires to have bald spots. We the service people could not find any bald spots they ruled the brake as a defect and covered them under warranty. I just find it unusual that the rear brakes would do this so early in the life of the vehicle when the front brakes look like they have barely been touched. If I had been taking a turn or having to brake in an emergency I dont know what all could have happened when I have rear metal to metal instead of the oem brake pads to protect me.

The rear brakes on the 2008-9 Cobalt ss are causing rotor scoring at 400+ miles. The pads are too aggressive or the rotors are too soft and the rotors are being destroyed which could lead to brake failure if not replaced.

Brake pad failure: at routine service, 17,665 miles, dealer found rear, inner brake pads excessively worn. Right pad was gone, rotor being scored. Left was less than 5% remaining. Other pads within normal limits. Replacement pads are not in stock at gm, back-ordered.

My 2009 Cobalt ss has 10,800 miles and at 7k miles, the rear brakes began to squeak. You can feel that the rotors in the rear are grooved terribly, and the inside of the rear pads are even worse. The car is at the dealer now getting this fixed after I had already taken it to another dealership and they wrote it off as "wear and tear". Rear rotors do not get worn out in 10k miles.

My original complaint is 10263782. I now have to have the rear brake pads replaced again. Went from new to 3/32 in less than 4000 miles. In less than 12,000 miles the rear inner pads have been replaced twice and the rotors resurfaced once.

On my 09 chevy Cobalt ss the rear brakes got very loud. The failure was the inner rear brake pads went metal to metal by 8000 miles from new. The outer pads were like new. Dealership resurfaced the rotors and replaced the pads. They had the car 5 days and gave me a rental. 2000 miles later and the brakes are getting loud again.

Uneven brake pad wear on the rear brakes. Squeaking and squealing persists. . . Dealer has turned rotors and replaced pads. . . Problem persists.

I have a 2009 Cobalt ss. About a couple months ago I started to here some scratching coming from the rear of my vehicle I looked at my breaks and the rotors were damaged I took it to the dealer and they said breaks are not under warranty because its an wearable item and because of the damage to my rotors they were to damaged to cut so I bought new ones with break pads because they were cracked as well I am not the only one with this problem so please look into it.
