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.

The vehicle started to emit an odor of fuel when parked, not running. A few days later a visible puddle of fuel was under the body of the car. This has been recurring every day since the first occurrence. Now a visible leak from above the fuel tank can be seen dripping fuel at an accelerated rate.

My car has been mildly having problems when you would stop at a light or pull into a parking spot it acts like it wants to cutoff. I got the letter on the recall and it definitely gave me anxiety driving the car especially since I have to travel 180 miles quite often for my kids. I had the recall fixed and yet still had the minor problem. I say minor only because it did not cause anything bad to happen at that time. Also noticed that my car was not acting right with the two keys they gave me sometimes it would start and sometimes it locked up. But not every time. About two months after that I went to lunch and my key got locked in the ignition and the car would not start. Figuring I trust be the battery I went bought a new battery but the car still wouldn't start. I had it towed to GM dealership and they told me it coded for the ignition switch and the fuse box. But then called me back and said it was the fuse box and the body control module and the fuel pressure censor. I tried to trade it in and the value of a car I bought just a year and a half ago for 11,999 is now only worth $3000 even to the maker of the car I would be stuck paying on a car that is unsafe still and makes it to where I cannot get a new car because of the amount I still owe on the vehicle.

Gas leaks from top of gas tank, can cause fire, and throttle switch causes engine to loose power, I have had it cleaned and it works, but now I have second Cobalt, and it does the same thing with throttle switch causing car to run under 20 miles per hour. The power reduction can cause engine to overheat and the leaky gas tank can catch fire. Someone should look into this issue asap.

Hi there about two three weeks ago I started smelling fuel every time I got out of my car. My husband checked and it looks there is a hole in the gas tank that or the tube that allows the gas to flow is cracked. I saw that there was a recall for this but only in vehicles that are in Nevada, Arizona and Texas.I am not driving the car currently due to safety reasons. Every time gas is put in the car you can hear it leaking out the bottom. I am not sure what to do to fix this. Can some one help me?? thank you.

I have been smelling gas inside and outside of my vehicle. I was told it maybe a gas leak, but no gas residue was found on the ground then I was told my gas cap may need to be replace. So I went to autozone and had it checked out and was told my gas cap, transmission and battery was good. You can walk pass my car anytime of the day without it been cranked up and smell gas. I done did some research and seen their was a past recall similar to this but was told it was fixed in the past. (I guess way before I purchased this vehicle) but now im also seeing im not the only one with the issue, what can be done about it and since so many people are having the same problem why not do a recall on it? I done put so much money into this car and only had it 16 months, this is ridiculous, frustrating and definitely not safe. Pretty sure not good for me and my kids health and this is my only transportation as well.

I have the smell of gasoline coming from the car and find that it is coming from the area of the gas tank. After further investigation I find that certain Cobalt models have been recalled for this matter. Where the seal around the fuel pump cracks and leaks. However I am told that for some reason my Cobalt model is not in recall for this situation. Why not. If some of these vehicles have been recalled for this problem then obviously the problem should be corrected with this vehicle as well. I would like to know how I go about getting this problem resolved with this lemon of a car.

I have a 2006 Chevy Cobalt. I have had issues with every part that has been issued a recall so far and then some. The latest issue is that my car is leaking gasoline under the driver side door. I see that there was a recall issued for this in 2009, but only for vehicles in certain states, in which I do not reside. I have also had issues with my ignition for several years, so it is good news that a recall has come up for it. Before the recall was issued for the power steering pump, I had no power steering for six months prior. I think that it is repulsive that GM can manufacture this car and just issue recall after recall with no consequence.

My car was part of the GM recall for the incorrect ignition switches. It was returned to me on July 23rd, fixed or so I was told with a new ignition to fix the issue. However within a week of having the car back, it was doing the same as before the recall fix was done. Slipping into accessibility mode and not giving me any option to hit the gas, only pull off if I was able, turn the car off, then back on and go. This happened a couple of times when I was going upwards of 40 mph. The last few times this has happened was pulling from my street into a busy street with traffic going upwards of 55 mph. I had to pull off as quickly as I could onto the shoulder and turn off the car, back on again and go meanwhile hoping to not be hit. I contacted GM again and was told that my recalled part was fixed and this had to be another issue. However, it's the exact issue that happened before my car was fixed. I'm 7 months pregnant and often drive with my 16 month old son in this car with me. I do not feel safe driving it and cannot just go purchase a new car. I feel like this needs to be looked into further to find out if there are more issues after the initial recall fix.

We can smell gas coming from the car. We can't even put our vehicle in our garage because it smells up the whole house like gasoline. My husband took it apart and said that there is a leak in the fuel pump. I went on line and notice that there was a recall for this but only in certain states. Why is that" what do we do now" we are afraid to drive it because we are afraid that it will catch fire. Please advise.

  • 100,000 miles
My wife and I have a 2006 Chevrolet Cobalt in August 2012 I noticed a gasoline smell coming from the car. I took the car to a shop and they found the fuel pump assembly was cracked. Luckily we caught the problem early and fuel had not been leaking really bad and we had the problem fixed. Due to the newest recalls on the Cobalt I decided to look into previous recalls on the car and saw that there had been a recall on this problem in 2009 on the Cobalt but only for cars registered/bought in 5 states(Illinois not being one). We find that to be extremely unacceptable and dangerous. All the Cobalt model years have a recall on a faulty fuel pump problem but only for cars bought and registered in 5 states that's just crazy. If a car has been deemed unsafe enough to cause a recall in five states why was it not done for all the states/all the Cobalt's. this is just ridiculous.

My 2006 Chevy Cobalt ss supercharged started malfunctioning in Feb 2013 driving the hwy the car would jolt as if it was running out of gas same thing occurred on April 2013. The big problem happened Sept 2013, driving 75 on the fwy my Cobalt started to jolt and loose power and the speed started slowing down all the way to 30mpg I was barley able to make my way through traffic to get to the side of the road, once pulled over my Cobalt didn't want to start and when it did it would only go about 100 feet and slow down then turn off. Since then my Cobalt has not been able to function properly. At low RPM's it dies off. Since that day my boost gauge doesn't work. My mpg's have dramatically fell about 10, ill fill up half the tank and the next thing you know it drops to empty. Also while driving when I hit pot holes the car turns off. It has a hard time starting up. I've read through the forums and other people have had this problem. Is there a recall for this yet and if not who not"! wouldn't you think cars failing on the fwy is a major red flag"

My vehicle smells of gasoline and has been leaking like crazy. I am getting less than 17 miles per gallon and losing a ton of gas due to the fuel pump recall. I believe that it should be under recall in every state and not just a few. If it is recalled on any 2006 Chevy Cobalt I believe it should be recalled on all of them no matter what the state. I live in Michigan and therefore its stated there is no recall for it here. I am very disappointed in this and in GM for selling a car with as many recalls as the Cobalt has and only choosing very few states for the recall to be granted. I used to be a huge GM fan but, now after having as many issues as I have had with this car and living in Michigan not being able to have it fixed under recall, I no longer feel the same, in fact I am strongly thinking of going foreign. Thanks GM for letting down yet another customer. Please get back to me when you want to take care of your customers everywhere and not just in certain states. This is your fault that the car is so faulty and I think you should stand up and own up to it and fix the Chevy Cobalt's no matter what state they are in. How does it even matter what state a person is in anyways a default part is a default part, isn't it?

I have been noticing the smell of gas from my car for about 2 months. About a week ago I saw a puddle of gas on the garage floor. I took it into the shop to have it inspected and was told the fuel line is leaking due to a part the manufacturer placed on the vehicle that is defective and rusted. Upon doing further research I have found that many owners have experienced this problem and the manufacturer has issued a recall but only in certain states, none of which are mine. I feel this recall should be for all vehicles. It should not matter what state, as it is obvious this defect is affecting vehicles in all states. The consumer should not be responsible for the cost of this repair as it is due to the faulty manufacturing.

Since I bought this car in may of 2011 I have had nothing but problems. In March of 2012 my fuel pump went out while I was driving due to a recall from several years earlier, which I don't understand why it wasn't replaced before I bought the car especially if I bought if from a dealership. In January of 2013 my gear shift assembly went out luckily after I was done driving and in the process of parking which resulted in my keys getting locked in the ignition. A month later my switch board stopped working in my steering wheel which turns off my signals when I turn and my keys still occasionally get locked in my ignition. My O2 sensor just went out, shortly after I got the car I learned one of my valve covers is leaking oil, and I just replaced my ignition coil pack! I am afraid to drive this car any longer especially with the new recall about the ignition. This car is a hazard to anyone driving it. I should not have this many issues when I have only owned the car for three years. I believe GM should recall the whole car. I tried taking my car to the dealership in February to inquire about the recall and they sent me away and said to wait to receive something in the mail to see if my car qualifies. Seriously"?" I'm not sure what actions I should take to ensure my safety. I don't have the money to fix this car that has everything under the hood failing all at once! every day I drive this car I am putting myself in danger. Any information back would be greatly appreciated. Thank you.
