| While driving to work, steering wheel had been shaking (55mph). getting off the belt line, traffic came to a sudden stop. i braked, but the car continued to shake and didn't brake. had to pull to the side to avoid hitting the car in front of me. car would not accelerate when traffic started up, and i had to turn the ignition off and restart. car shook badly for a few seconds, then seemed fine. a few days later, driving into my parking lot (10mph) the car's brakes locked up for no reason and i barely got it into a parking space. took it in to the dealership the car was purchased at and was told the rotors, brakes, and calipers would need to be replaced. had another mechanic look at it and had the brakes and rotors replaced. car drove fine. six weeks later, driving on the highway (60 mph), slowed down to turn onto another road, and brakes were out. had another mechanic look at the car, brakes and rotors are worn down again, as well as calipers and brake line. road conditions were clear at the time of each incident. | |||

| I have a 2006 chevy cobalt ls. it has been giving me several problems. i have been fixing one thing after another on my car. my car only have 46,000 miles. that is good for it being a 2006. i have problems with my brakes. i have replaced the master cylinder and now i have to replace the brake booster. but the worst problem that i am having now is the power steering. when im driving out of nowhere the dash light up saying power steering. when this happens it is extremely hard to turn. especially if you are going at a slow speed. i have even been in an accident because of this. the only way to get my power steering to work normally is to turn the car off and turn it back on. at first it would work fine for awhile. but now it happens right when i start to drive. the dealership said it could cost over $1500 to fix the problem. i can barely afford to fix these other problems that i am having. i cant afford to pay $1500 to fix this problem. i was online looking to see if i can find a cheaper price. this is when i saw that there are hundreds of other people that have and still have the same problem that i am having. this is how i know that it is not something that i have done. with so many people having this problem, they need to fix it. *tr | |||

| I purchased a 2006 cobalt ls level 2 used in october of 06. shortly after the purchase my car started a moderate tone whistling and my heater started making a clicking noise which both are very annoying. i have brought my car to the dealership whalen chevrolet in greenwich ny many many times and all they ever say is the noises are normal there's nothing they can do about it. shortly after those problems came about my wipers stopped working in a storm for no apparent reason,when i brought the car to the dealership for this problem they blamed it on me saying i was mis-using my wipers ,apparently your not supposed to use them. within days of that problem my car started to bump when i'd touch the brakes, once again i brought the car to the dealership and what do you know the dealership said it was my fault and the brake rotors needed to be planed down. still to this day the car is whistling the entire time it runs and the heater is clicking away like always,it is apparent to me that this is no replacement for the lack luster cavalier,it is the cavalier it's just prettied up a bit. to this point the shabby engineering of this car has cost me well over $500 in repairs & diagnosing to try and solve a problem the gm certified mechanics at whalen chevrolet in greenwich ny can't seem to figure out---oops i mean it's supposed to sound like it's falling apart. *tr | |||

| 2006 cobalt had vibrations at highway speeds. customer states if they stop and turn the vehicle off and on it will temporarily correct the vibration problem. *kb the consumer stated since purchasing the vehicle, the vehicle has had an extreme vibration at high speed. the consumer stated the vehicle has become so dangerous and hard to drive that at times he would have to pull over to the shoulder. the consumer stated after several attempts to assess the problem balancing the tires and replacing 2 of the 4 tires, he was informed by dealer the rotors were out of round and left tire was worn. the consumer stated due to the fact the 2 chevrolet dealers were given ample time to assess the problem, he feels this should fall under the lemon law of a refund or a replacement car. new tires were placed on the vehicle and balanced. *tr | |||

| I purchased a 2006 chevy cobalt ss w/ 2.4 liter non-supercharged engine. at about 5,000 miles the car began shaking while braking. i took the car to the dealership and they informed me that the front rotors were delaminated and they machined them down smooth again. this fixed the problem for about another 5-600 miles, then the shaking started again. my car had to go back to the dealer again and they machined them down again without replacing the rotors-they said they just pass inspection. also, they informed me that the head gasket, the valve covers and the exhaust manifold all needed to be replaced. this is the sixth day they had my car and everyday it is something else they find wrong with it. my car only has 15,000 miles on it and is well taken care of. i feel that the braking power of the car is decreased, even after the rotors are fixed, i fear i may get into an accident because of this and no one at denoyer chevrolet on wolf rd in albany, ny tele#518-458-7700 cares. the person that is updating me with information on my car is jeff winne and he is very rude. i hope this matter can be further investigated to prevent any further injury. *tr | |||

| On a regular basis ( about once a day ) the brake lights stay on when the brake pedal is released. to shut them off the pedal must be lifted slightly. there is no feedback that this action is ocurring other than from other drivers following the vehicle. the manufacturer can not fix the problem. *nm | |||
