general problems of the 2009 Chevrolet Cobalt - part 1

Coming out of a roundabout in rush hour when a car ahead of her suddenly stopped. She had about one and half to two car lengths and her speed was about 35 mph. She applied her brakes and they did not respond. Her car rear ended another car. The airbag deployed. She has a sprained neck and back. She has been off for a couple of days per doctor's request. Major damage to the entire front end of the car.

Rear brakes wear out way too quickly.

This is the second time this issue has happened. The issue is when turning on an on-ramp that has sharp turning radius the car abs system turns on and you lose control of the car. This also happens when you are already on a freeway that has a sweeping on ramp to another freeway the abs starts to brake in the turn. I have reported this issue to the dealership and they have not addressed it.

On Thursday October 9th, 2014 I was driving east on rt 70. It began to rain heavily at approximately 4:50pm and I attempted to use the breaks on my vehicle. The breaks were suddenly very stiff. I didn't think they were working. I was in the left lane when this occurred and immediately put on my emergency lights and tried to move to the middle lane, to the right lane so I could go to the shoulder. When I attempted to switch the lanes, the power steering wasn't working. I managed to move the steering wheel slightly so that I could switch lanes. There was oncoming traffic before an available shoulder so I tried to speed up. I was unable to increase my speed. I was able to slow down naturally but I wasn't able to completely stop until I got to the shoulder and pushed extremely hard on the breaks and held down on the break for several seconds. The radio was still working and the heater was blowing cold air. I was able to get the vehicle working again by turning the ignition to the off position and turning the ignition back on. I think my vehicle's engine turned off while I was driving. I have onstar on the vehicle and immediately pushed the button when I was unable to break properly with my vehicle. The lady I spoke with said that she was seeing some problem with my breaks but I took my vehicle to the local dealership the same day and they found no codes for my vehicle. The next day the dealership told me that they fixed the ignition recall on my vehicle and that might have fixed the issue. On two other occasions before the recall was announced, I had a similar issue and brought it into the dealership. They couldn't find anything wrong. This experience was terrifying and I'm just glad that I wasn't killed.

As I was driving down the street to turn into my parking lot I started turning the wheel left when I turned my steering wheel and brakes locked up and drove over the curb of my apartment complex causing my whole right side of my car $1300. 00 worth of damage this is the second time this has happened to me first time no damage was done that was back in October.

Rear breaks wear out very fast for a new car, also very noisy and destroy my rotors. Outter pad seems fine, inner pad is deteriorating at an alarming rate.

The contact owns a 2009 Chevrolet Cobalt. The contact stated while driving approximately 40 mph, the brake pedal was engaged and the vehicle continued to accelerate. The contact crashed into another vehicle. The contact suffered an injury to the neck. The air bags failed to deploy. A police report was filed of the incident.

The contact owned a 2009 Chevrolet Cobalt. While driving 40 mph and attempting to come to a stop, the brake pedal was depressed, but failed to respond. The brake pedal depressed all the way to the floorboard independently. As a result, the vehicle failed to stop and crashed into the rear of another vehicle. The air bags deployed with excessive force. The contact had to puncture the air bag to avoid suffocation, which caused the air bag to explode. The contact sustained back, neck, and ear injuries that required medical attention. A police report was filed. The vehicle was towed to a towing yard and was deemed destroyed. The manufacturer was not notified of the failure. The failure mileage was 48,000. The VIN was unavailable.

Rear brakes are dragging on the rotor and grinding at stops.

I purchased my 2009 Chevrolet Cobalt ss sedan a little over a year ago. Within the first several months, the emergency brake started to get extremely loose. It than completely stopped holding within 6 months and 40,000 total miles. After this incident, the rear brakes and rotors began to prematurely wear out extremely quickly. Since these are not covered under any warranty and dealerships refuse to fix the issue for free, it's very costly out of pocket for the repairs. I can't park anywhere near on or a hill, due to the emergency brake being completely broken. And the rear brakes and rotors need either repaired or resurfaced constantly every several thousand miles. My other major issue is with the tpms (tire pressure monitoring system) this has been giving me an error constantly for around 10,000 miles, on how it needs to be serviced. My car is garage kept with maintenance done on time, and well taken care of.

I have a manual Cobalt ss 2009 and the emergency brakes are not working. I have to have the emergency brake to park my car. I been having to rest my car in a gear so it will not go anywhere.

The rear brakes started making some noise at 15,000 miles. Looked at them and didn't see any unusual wear. Checked again at 18,000 miles and the rear rotors on both the drivers side and passenger side are scored terribly, was going to get them resurfaced but the metal is beyond repair. I checked online for a possible fix when I came across a forum site specifically for my car that has listed multiple incidents in this same nature with the same car.

Rear brakes on my 2009 chevy Cobalt ss are [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2009 Chevrolet Cobalt ss. The contact stated that when trying to decelerate he noticed that the brakes would make a loud scraping noise.

Rear brakes wore too quickly for a front wheel drive car that only have 10,000 miles on it.

The contact owns a 2009 Chevrolet Cobalt ss. The contact stated that while driving at highway speeds, the front and rear brakes pulsated when they were depressed and the steering wheel vibrated. The vehicle was taken to an authorized dealer who stated that there was nothing wrong. The vehicle had not been repaired. The failure mileage was approximately 16,000.

This has been an ongoing problem for over a year now. I take my vehicle to the dealer and tell them the rear brakes are locking up and they respond with "this is caused by driver abuse, you have been powersliding it" I have had it to three different dealers. The rear brakes have been replaced 3 times within 9 months and are now needed again. Chevrolet states they are not willing to fix the problem.

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.

Rear brakes make scratching sounds and the inside of both rear rotors have been scored deeply this was noticed at 5000 miles when I bought the car and has got much worse at 17,000 miles. Also took it to my dealer and the would not replace anything.

Premature rear brake rotor wear.

Premature rear brake wear.

Rear brake rotors scored horribly with only 10k miles.

Have 2009 chevy Cobalt ss and has had to turn my rear rotors for the 5th time since I got this car brand new, at 36,000 miles now.

I bought a 2009 chevy Cobalt ss used with 9000 miles on it. From the day I bought it I consistently heard rear brake noise whenever I stopped the car. There is excessive pad wear on the rear brakes at 11000 miles now. Way too much wear than normal. Deep scoring in the rotors. Took the car to the dealership I purchased it from and they resurfaced the rotors but the problem was still there after I drove the car home from the shop. So far nothing has been done to correct this problem by the dealership of chevy.

Bought my 09 Cobalt ss with less than 1,000 miles and my rear brakes squeal and grind horribly with only 11,500 miles.

Rear brakes on 2009 completely worn after only 35,000 km.

Rear brakes grinding and squealing I am in fear of my life with all the car recalls brakes are not something to mess with. . . I am afraid to drive my new gm Cobalt ss for fear of an accident and failing brakes !.

The rear brakes started squeaking really badly at 5000 miles on my new 2009 chevy Cobalt ss. While performing a tire rotation, I inspected the brakes and rotors for unusual wear. I noticed two really deep grooves/scores on the backside of the driver side rear brake rotor. I took it to the dealership where they agreed that was not normal wear and replaced the rotor. The brakes still squeak but not as bad. It is unfortunate though that I have to drive around in a new car and am embarrassed to come to a stop with all the squealing. I was handed a TSB (#08-05-22-004) stating that squeaking brakes are normal and are not to be repaired. I can assure you that no one told me to expect such awful noises from my new car within the first five months of driving it.

Rear brakes noisy and pit very easily.

I purchased a new 2009 Chevrolet Cobalt ss sedan. The car has barely broken 10k miles. The brakes are wearing abnormally fast. I am very gentle with them always, and they are very worn already. Pulling up to stop signs or traffic lights is ridiculous. The screeching from the brakes is loud. I have never had brakes go out this early on any of my other vehicles.

Rear brakes on 2009 Cobalt ss t/c only 1500 miles on the car and rear rotors are absolutely trashed. Outside pad looks good inside pad is down to the medal.

Had to replace rear brakes on 2009 Cobalt ss after ~ 12000 miles. Rotors had to be replaced. Made very noticeable screeching and grinding sounds. Brake performance had decreased very much even before they were replaced, decrease in performance of brakes at about ~7000-8000 miles.

Well, I put in a complaint a while ago about the rear rotors wearing fairly quick. Now the rotors need to be completely replaced. The inside part of the rotor is extremely damaged and now braking distance is nearly 1. 5 times greater than before. Its dangerous.

I have a 2009 chevy Cobalt ss. At approx. 4000 miles the car was taken to the local chevy dealer due to the rear brake rotors deeply grooved. The dealer turned the rotors and reinstalled the brakes. At approx. 7000 miles the rotors are starting to grove again. The dealer replaced the rotors after a lengthy conversation with alot of reluctance. The dealer states and has a bulletin for GMC that noise and squeal are typical with a high performance brake system. Please note it's not the squeal that concerns me it's the deep grooving of the rear brake rotors. Although it hasn't turned into a safety problem yet it is a concern. I hope you will investigate this problem before it becomes another Toyota and people are hurt or possibly killed be cause of prematurely grooving and wearing of the rear brakes on this car.

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.
