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.

Wheels- the control arm bushings wear tremendously and rattle making the steering wheel shake uncontrollably. Steering- the steering wheel has a ton of "play" before it engages in a turn. Brakes- the rear drums and shoes wear excessively fast causing severe deterioration and grinding.

I was driving on the freeway when I changed lanes and lost control of my vehicle. My anti-lock braking system did not work as it was supposed to; my traction control did not work as it was suppose to, which resulted in me losing control of my vehicle and hitting another vehicle. A month earlier, I took my vehicle to rancho motor company to have a recall part on my vehicle fixed. They noticed that my ABS and traction control lights were on. They ran a diagnostics test on the vehicle. When I picked up my vehicle, they informed me there was nothing physically wrong with my vehicles ABS and traction control systems but the software was outdated and needed to be updated.

I was driving on the everett turnpike in nh. There was a soccer net in the middle of the highway. The cars in front of me had stopped and I tried to stop, but because my power steering was out along with my anti-lock brakes. I couldn't stop. I hit the car in front of me and my airbags didn't deploy. Luckily the only damage done was psychological. If I were an inexperienced driver than I would have died.. I have already had my power steering fixed once and now it has been recalled again. The car as a whole should be recalled. I don't feel safe driving it after they fix a problem that has already happened twice.

While driving in the left lane on a multiple lane interstate highway the driver on my right changed lanes into my lane. On my left was a concrete barrier without enough room for me to avoid the other driver. I aggressively applied the brakes to try and avoid the other vehicle. Even though my vehicle has ABS (anti-lock brakes), the left front brake locked up and pulled me into the concrete barrier. At no time in the life of my car have I gotten any indication that the ABS system wasn't working properly. In this situation I would have been much better off not having ABS than having the system only to have it malfunction on just one wheel.

My most important issue with my 2008 Cobalt lt is that my engine is gone which I think is horrible and I purchased this car brand new I have been the only owner and have taking very good care of my vehicle, I will never buy a GM product again, through reading all the complaints I cant believe this vehicle hasn't been recalled my car started shaking really bad, and making a loud ticking noise, it was very hard to stop and also steer my vehicle I could have been in a very fatal crash or anything! my car also has the same issue about the speakers they go in and out and work when they want to. But my main issue is my engine in which my car I is longer under warranty and the dealership said it is nothing they can do for me, which I believe is totally absurd considering im still making payments on a vehicle that doesn't work, and is only 5 years old, so basically that means to me they will cover your car for 5 years or 100,000 miles then your just on your own which is horrible, to invest and buy a vehicle brand new and it just breaks down in this magnitude! I am very upset and disappointed that they aren't willing to help, so I will be suing them!

Since the car was purchased new, it has made occasional grinding noises from the rear brakes. The rear brakes have worn out so quick that this is the second time they are being replaced (three sets of rear brakes in under 50,000 miles). The replacements have not been covered under warranty because they are a "wear" item. This vehicle is the four-door "sport" model with the rear disc brakes and manual transmission. The problem is that the brakes wear very quick and the parking brake will no longer hold the vehicle on an incline. The emergency brake was adjusted by the dealership twice and they said there is nothing wrong with it, but I figured out what the problem is. The springs on the rear calipers that release the pads when the parking brake is disengaged are not strong enough to release the pads. Even when the parking brake is fully disengaged, the rear pads are clamped down on the rotors causing heat, premature wear, and more rolling resistance, leading to decreased parking brake function.
