2009 Chevrolet Cobalt SS brakes complaints
Page 5 of 7: complaints 101 to 130 of 163, newest first, as owners wrote them.
Extreme rear brake pad wear and damaged rear brake rotors after only 3,500 miles. 2009 cobalt ss sedan.
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.
I have a 2009 chevy cobalt ss that was purchased new in july 2009. The car has approximately 8000 miles on it. My concern, like many other cobalt owners, is the premature wearing of the rear brake rotors. I noticed the rear brakes starting to wear out around 5000 miles. The rear rotors have deep gouges in the face of the rotor. They are now starting to squeal when coming to a stop. This appears to be severe, premature brake wear, especially since the front brakes should be doing most of the stopping.
I have a 2009 chevy cobalt ss and the rear brakes are getting grooves in it bad. Only 1500 miles on it when it started. Pads have good amount left but they make this god awful squeal. Like they been driving on them for over 50000k but not even 10000k.
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.
My rear brakes rub. They are very loud and I only have 7,000 miles on it. There are marks in them. I was told that is normal. I did not know that chevy would install brakes that are loud and fail as normal.
My 2009 chevy cobalt ss turbocharged has rear disc brakes that are wearing prematurely, screeching/squeaking noises are occurring. My car has not been in any accidents and I've driven it from ann arbor, mi to lake orion, mi countless times for work and school. The front brakes work great but the rear ones are causing me trouble. Please address this issue, thank you much-
Noticed multiple times that my parking brake seemed to "hang up" when released. Took to dealer and they found nothing wrong . I am at approx 10,500 miles now and have no parking brake to hold my car. I was told both the inner pads on both sides for my rear brakes were gone and will need the rotors replaced also. Have yet to have brakes due to lack of available parts to replaced them.
Service brakes, hydraulic.
The rear brake rotors on my 2009 chevy cobalt ss are wearing and grooving excessively. Since the car was new they would squeak loudly and I noticed the deep recesses after only 1000 miles. I've been to two dealerships and they told me this was normal and it was how it was designed, one even said it was to keep rust of the rotor!
I have a 2009 cobalt ss and the rear brakes are already failing after a couple thousand miles of use on the vehicle. Gm needs to replace these rear brakes with a better quality product.
Vehicle rolls for/aft when "parked"...
I own a 2009 chevy cobalt ss/tc with less than 15k miles on it my rear brakes have become completely ineffective with unusual wear properties to the inside pad. This is the second time it has happened, and this time the pad material separated from the backing plate on the drivers side making the car pull towards the right anytime I slow down and lock the passenger side rear tire despite having ABS anytime it rains.
Deep groove in rear brakes. They are done at 17,000km.
Rotors are scored and need replaced on rear after only 15k miles.
Severe grooving on rear brake rotors after approximately 8,000 miles. Inboard brake pads are wearing faster than outboards. Also a noticeable grinding noise upon applying brakes. This issue was brought to the attention of manufacturer's dealer. I was informed that this was a normal condition and no repair is needed. Front brake rotors and pads appear to be wearing normally. Vehicle currently has 14,000 miles and rear brake issue appears to be becoming more severe.
Rear brakes are wearing too fast.
Brakes squeak hard when coming to a stop and continue to squeal until car is fully stopped. Took car to dealership under warranty and was told there was nothing to do a year later brakes still squeak nearly everytime I brake. New brake pads are needed!!!!!!
Rear brakes on vehicle begin by squeaking regularly. Upon inspecting them at roughly 6000 miles on the brand new car, the inner brake pads are completely worn while the outer pads are nearly new (as they should be). One possible cause of this is that the parking brake spring is not strong enough to hold the inner pads from rubbing the rotors when the parking brake is disengaged. Gm should recall this brake issue as it will continue to cost buyers hundreds every few thousand miles, when all that is needed is likely a spring with a better spring rate.
Premature wearing of rear brakes.
I have a 2009 cobalt ss, and am having a problem with the rear brakes grinding, and making noise. I have had them checked at 6,000 miles and the rotors and pads were already real bad. Now at 11,000 miles had it checked out again and the inside pad is completely metal to metal and the out side pad is still like new. I think there are stuck calipers and making only the one pad do all the work. It is starting to have decreased braking ability and gm still wont warranty it.
Uneven brake pad wear on the rear brakes. Squeaking and squealing persists...dealer has turned rotors and replaced pads...problem persists.
The inside brake pads on my 2009 cobalt ss turbo chew up way too quickly. They wore out on the inside with less than a year of highway driving. They wear unevenly with the outside brake pads in the rear and the front brake pads, which are still the thickness of new.
This is my second complaint on the same problem, see #10278491. Excessive scoring of rear brake rotors. The dealer turned the rotors at 4600 miles, at my cost. Subsequently, chevrolet action center sent me a letter for $100 credit on service. Now at 7500 miles, they look pretty bad again. The dealer agreed this time to warranty pads & rotors, one time only. This is a manufacturing defect causing a safety problem. There have been a number of reports that the caliper pins were not lubricated at the factory, causing binding of the pads on the rotors. Others believe there is a pad/rotor incompatibility issue.
2009 cobalt ss rear brake rotors have big grooves in them dealer cut them once and then they got all grooved again.
My car has very low kms just over 1000kms and my rear brakes are already noisy and the rotors scored.
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.
Uneven rapid rear brake pad wear and scoring of rotors. The problem is very common with 2008 and 2009 ss models.
Rear brakes failing far to quickly, less than 23,000km, results in very loud screeching/grinding noise.
