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.

CarComplaints.com 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.

I started to notice a strong smell of gas about 2 weeks ago. I thought nothing of it and assumed I had spilled gas on the side of my vehicle when I went to the gas station. But then I started to notice that the smell would not go away. I checked the ground for leaks and found nothing. I checked my fuel injectors and still no leaks. Then I stumbled on NHTSA - where there were complaints of fuel smell outside the car. I then found out there were recalls in certain states - but not mine. Why"?"

Strong gas smell. There are recalls on fuel pump and parts in other states but not in. This should be on all Cobalts that have this problem. Indiana lives are important too! this is very dangerous and expensive to fix. I have seen many complaints due to this issue online. Why don't you step up and fix you mistakes GM?

I noticed a very bad fuel leak from under my vehicle back in the beginning of May 2015. I kept my vehicle parked until I could get the problem fixed. The middle of may I jacked up my vehicle to see where the leak was, I noticed it was coming from two of my fuel lines that run the length of my vehicle, the leak was in the same spot on both lines, in a bent part of the lines held up by a clip. I took my vehicle to a mechanic shop on July 23 to get a price and to get it fixed. I didn't have as much as it cost to get fixed. But the owner of the shop didn't want me to drive off in my vehicle, he said the it was way to dangerous and could catch fire. The reason for my complaint, I called the GM dealership to get a price on the fuel lines. The guy I spoke with told me this wasn't a new problem, he said several people has been there with the same problem. I asked to check for any recalls, he said there wasn't yet. Like there was going to be. He told me not to drive my vehicle because it was extremely dangerous until it was fixed.

Strong gasoline fumes; now I'm told it is a cracked piece on the fuel pump assembly just as described in GM recall no. 090226. $750 to replace; and it is apparently yet another known problem with this vehicle.

I have had two of these models in our shop and both being 2006 models. The fuel lines are rusting out at the support clamp near the frame on the drivers side. This location is about 4 inches from the exhaust. Fuel sprays on to exhaust and vaporizes. This allows fumes to enter the interior of vehicle. Fumes are dangerous and causing driver to become weak and drowsy. The potential for accident is higher then that of a politician actually doing their job.... please investigate this.

I live in buffalo, NY so this is more of a problem than not. During the cold months went he temperature goes below 20 degrees the car fails to start. I have replaced the fuel pump, spark plugs, intake, mass air flow sensor, and battery. I will be trying the crankshaft position sensor next. The car will crank strong, and continue to crank for several minutes. It will then stop, and begin to crank again when the key is again turned. However the car never turns over. The only thing I can imagine is that something is communicating with the ECM or ECU, not to start. This only occurs when it is very cold out as I purchased the car in late September, therefore I have to experience with the vehicle in warm temperatures.

I have been having an issue with a strong fuel smell and witnessed a large puddle of gas leaking under the car. Looking under the car I found corroded fuel lines on a plastic chassis bracket. Since the lines come from the pump running forward under the passenger side, this is a real fire hazard. The fuel lines are only a few inches from the exhaust pipe. Upon ignition this could ignite a fire. Several online complaints have been made to recall forums mentioning the same issue with the Cobalt model.in the passed their has been a recall, but only for the fuel pump, not including the fuel lines. Also, many including myself have went to the Chevrolet deal to get this problem solved. The problem is that they refuse to fix any unless I pay $600 or more for the fuel lines.the fuel lines are not even included into any warranty, yet the fuel pump is. Since there has been a major issue with this life threatening issue, the materials are obviously problematic and need to be recalled or revised.

I have a serious leak in my fuel tank. The location of this leak is on the passenger side near the rear tire. The fumes are so strong it can be smelled over 50ft away from the vehicle. I have literally had gas leak onto a friends hand when they leaned down to check for a leak. I myself am a 24 year old female, my passengers on a daily basis include a 24 year old male, and two children one of which is my four year old son and a five year old girl! this is extremely dangerous and members of our families as well as friends are extremely concerned for our safety! I am extremely concerned for our safety as well! you have a previous recall for the year make and model of my vehicle but only limited to a few specific states! this is a serious problem, I have read reports of many others having the same issues as me with this car. Something needs to be done and it needs to happen before something horrific happens to someone who is either in or near these vehicles!
