Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2006 Cobalt continued to carry the torch first lit by the 2005 model year. To be clear, that torch is burning bright with widespread power steering issues, electrical curiosities and a dangerous ignition switch defect which led to a massive recall by GM. This isn’t a great torch to carry.

The 2006 added it’s own special flare with gas leaks due to cracks in the “return portion of the modular reservoir assembly.” A recall of 2006 Cobalts was issued to fix the problem, but only to vehicles sold in or current registered in Arizona and Nevada, leaving other owners to pay for repairs themselves.

Between this car stalling while driving, giving owners fits with power steering failure and having it be a potential tinderbox because of gas leaks, we felt we had no other option than to award it our “Avoid Like the Plague” badge.

Experienced issues with stopping distance and steering in 2006 Chevrolet Cobalt lt. Had brakes, shocks, and struts replaced...continued to experience issue with stopping distance and steering...took in to dealer and was advised the control arms were "dry rotted' seems to me that this was the most likely contributing issue to the problem with brakes shocks and struts. In addition due to issue with the control rods the U-joint in the steering column has been bent causing problems with steering.

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.

The contact owns a 2006 Chevrolet Cobalt. The contact stated that the vehicle had issues with the engine surging. She took the vehicle to the dealer and they stated that there was a dirty injector, in which they replaced. In January of 2007, the vehicle was taken to the dealer and they reprogrammed the computer for the surging issue. In March of 2008, the vehicle was returned to the dealer for a recall on the injectors. In addition to the surging, the vehicle would also shake violently when coming to a stop. The brakes and steering would not function correctly. The vehicle was taken to the dealer in October of 2008 and the powertrain control module was replaced. In November of 2008, the contact took the vehicle to the dealer again in regards to the violent shaking. The dealer could not duplicate the failure and advised the contact to call a tow truck in the event of a crash because they could not assist. In November of 2008, the vehicle began shaking violently and crashed into the preceding vehicle. There were no injuries. The vehicle was taken to another dealer, but they could not duplicate the failure as well. A complaint was filed with the manufacturer and the contact is awaiting their response. She was advised to not operate the vehicle. The speed was unknown. The current mileage was approximately 17,250 and failure mileage was approximately 3,040.

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.

(3) result of above (2)after market cruise control takes its own mind and decides to fully accelerate until gearing down in hopes it 'awakes' the computer (automatic transmission),then cruise control will finally shut off.
