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 2007 Cobalt inherited most of the problems from the 2005 and 2006 model years, but toned them down (a bit). Sure, the power steering still fails and the car has a chance of going up in flames due to a cracked fuel tank, but it’s not as prevalent as the older models. At least not yet.

In 2012, the Cobalt was recalled for gas tank fires but only for owners in certain states.

Then in 2014, the 2007 Cobalt was part of a massive GM recall due to a defective ignition switch that could cause the airbags to not deploy during an accident. The problem led to 13 deaths, government investigations and multiple class-action lawsuits.

After exiting the vehicle, the smell of raw gasoline was noticed. On February 4, 2013, while having new tires installed, a local service center notified us that gas was leaking from the top of the gas tank.

Cobalt 4-cyl

  • 80,000 miles
Cobalt began noticeably loosing fuel and appeared to be losing power when gas pedal was pushed. Shortly thereafter the check engine light came on. Within a few days every time the car was driven the loss of power while driving progressively got worse. Drove the car to a "certified GM mechanic at the local Chevy dealership" for a diagnostic check who stated the car needed a new motor; ($ 3000.00). Had to have the vehicle towed from the "certified Chevy repair shop" to a different mechanic because it now would not even start, which new (honest) mechanic said there is a major problem with the fuel pump/fuel propulsion system. Consequently while doing some research online we are now finding many complaints similar to ours on this make and model but for some reason due to our geological location our vehicles are not under the 2009 recall for fuel/propulsion issues? is appears obvious that it is a manufacturing issue that should cover all 2007 Chevy Cobalts not just some in a few select locations.

We took our 2007 Chevy Cobalt into our Chevy dealership here in roseville, ca to get our recalled fuel sensor replaced. We were then notified that our fuel tank needed to be replaced due to a crack in it, and that we are now looking at an $800+ repair for a new fuel tank. This car has never been in an accident or anything, so I know it did not crack from that. After doing a little bit of research I have found that a number of people are being affected by a) the sensor failure, outside of "qualified" states, and are not being addressed, and B) a number are getting the same call from dealerships about their whole fuel tank needing to be replaced due to this cracking. To me it seems that Chevy probably used the same materials on the fuel tank as they did this sensor that needs replacing due to "heat". now along with the sensors cracking, the tanks are doing the same only they are not covering them in a recall. I find it hard to believe that these complaints are just coincidence and that I can find a handful of complaints online about the same thing, who knows how many people have been affected by this issue and are now set back over $1000 for the repair.

Vehicle reeks of fuel and has a fuel leak. GM offered a recall in several states stopping at the one right below mine because the heat is the problem. Vehicle isn't driven nearly as much as others due to short distance to work, but they will not repair the problem.

Cobalt 4-cyl

  • 55,000 miles
The plastic supply or return port on the fuel pump module in my vehicle has cracked which caused a fuel leak. I started to notice a strong odor of gasoline on the passenger side of my vehicle in late August. I called a local Chevy dealer and took my car in to have it checked out. I was informed that there was a recall for the fuel pump module for some 2007 Chevy Cobalt and while my VIN was within the affected numbers, my vehicle was not covered because of the state where it was purchased/ I reside. I have two young children and am not happy that GM would allow owners of their product be in danger when they know they have produced a faulty product. If recalls were issued in Arizona, California, Florida, Nevada, and Texas why do the rest of us have to deal with it"??" I read in usa today that GM would offer a repair to those experiencing this issue who were within a certain mileage but have not heard anything more from GM on this issue. "but the company also plans to send letters to owners in other states offering a free repair within a limited time period if the parts are cracked. That offer is valid for 10 years or 120,000 miles from the date the vehicle was sold, spokesman alan adler said." (

I started to smell a strong odor of gas and called to schedule an appointment with a local dealer. They discovered a fuel leak possibly from a crack in the fuel pump. Unfortunately, my car isn't covered in the recall because I don't live in one of the "affected" states. Smell is so bad we don't drive the car with our kids in it anymore - causes headaches. Waiting for GM to mail letters about this issue to everyone who is affected regardless of where they live. According to an article from October 2012 "..the company also plans to send letters to owners in other states offering a free repair within a limited time period if the parts are cracked." ---> hurry up GM before someone who isn't covered but has this gas leak gets hurt.

The plastic supply and return port on the modular reservoir assembly is cracked. Fuel is leaking from the area. Fuel can be observed dripping onto the ground. I am extremely worried about a fire. I have contacted a dealership about the issue and they have said my VIN is not included in the recall and the repair will be close to $700. This appears to be a common problem with this model year and make of vehicle as I searched online and there were thousands of similar issues that are "outside" of the affected area.

Started noticing strong gas smell with or without the car being on. Also hard to start. Took the car to get the power steering recall fixed at our dealers, they checked the fuel system because of the strong gas smell and said the fuel line was probably cracked. Looked to see if it was under recall. Not for our state. Had to sign a paper saying our car was "unsafe to drive". we live 10 miles from 2 states that this is a recall in. Called Chevy and was told they would do nothing for us because the recall is not in our state. I want this fixed. Its time you stood by your products.

Cobalt 4-cyl

  • 45,319 miles
I received a recall notice for the fuel pump which indicated that the fuel pump module may crack and cause a fuel leak. As the technician was in the process of removing the gas tank to address the fuel pump recall issue, he identified a fuel leak at the filler neck on or to the gas tank. In the end, I had to replace the gas tank, but the fuel pump recall did not cover the cost. I am reporting this because I believe this could be a safety hazard due to a fuel leak. I did not find a recall for this issue.

Cobalt 4-cyl

  • 103,201 miles
My 2007 Chevy Cobalt started smelling very strongly of gas fumes- so much so that I was afraid to start it in the garage & began parking it outside. I then noticed puddles on the ground and my gas mileage dropped drastically from my average 30-32 highway mpg to about 18-19 mpg. I am currently overseas on military orders in germany. I had to wait for an appointment and got the car checked out and was told it has a major gas leak and is not safe to drive. It has a crack in the fuel pump and needs to be replaced. My complaint is that the recall on this defective fuel pump is limited to "warm weather states." A defective part is a safety concern that knows no geographical boundaries. I have been accumulating a lot of debt from having to have a rental car, which I am driving for safety reasons, until I can get an answer as to whether GM will replace my defective fuel pump. I should not bear the burden of the cost in addition to the inconvenience due to a known & recalled defective part based on my geographical location.

My car began smelling of gasoline and got worse over a few days. I took it to my repair shop and they had to replace the fuel pump. I then saw that there was a recall for this very same problem. I called GM and was told there was nothing they could do because I took it to an unauthorized shop for repair. Was I suppose to drive around in a car leaking gas until I could get to a shop they liked? I read on the internet that I was eligible for a reimbursement if I had already made the repair.
