CarComplaints.com 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.

So I filled up the tank then hopped in and took off. When I got out I smelled some gas, thought it was weird cause I didn't spill. Had the gas smell on and off but couldn't track it down. Started noticing that it didn't like to start in the mornings, until the pump fully kicked in. Just dealt with it for a couple months.

It was now time for the annual inspection, so took it in. They said that it is leaking fuel from on top of the gas tank. Did some research online and determined that it was a cracked fuel line on the fuel pump, a widespread issue. Also found out that there was a recall that GM had issued, but sadly expired in 2016. Local dealer says they won't do it free with the expired recall, but they will fix it for $1600.00. Well, ended up parking it to save up money to get it fixed.

Fast forward 7 months. Talked with buddy of mine about it. He looked into it. The dealer required exchange of entire fuel system including fuel tank, but the issue is only the fuel pump. Went to local parts dealer and picked up the new pump. Buddy and I changed it out in 2 hours for only $275. Good as new.

I bought this car at auction under green light warranty, finding out later it had a salvaged title. Gas odor started almost immediately after putting gas in. now it leaks badly if I fill it up,but still leaks vapors even when sitting. GM said they would cover the costs under "Special Announcement" to a previous recall that covered only southern states. Obviously it took a few years longer to crack in KY's climate, Local dealership said they could not cover any because of the rebuilt title. I am trying to find any help at the moment. Looks like I got burned on the car, but could also get burned up in the car. Safety should come first, but GM does not agree.

Cobalt LS Sedan 2.2L Ecotec

  • Automatic transmission
  • 100,458 miles

The car wouldn't accelerate under medium to hard throttle, so it was obvious the fuel system wasn't doing it's job. I took the car into the Chevy dealership knowing the fuel system was currently under recall. To my surprise, the service representative notified me I had a fuel leak right where the gas filler neck connects to the gas tank. I politely asked to see the leak with my own eyes and the leak was very easily spotted. I had recently experienced a drop of three mpg city, and the leak is surely to blame. I was loosing two gallons per fill-up (13 gallon tank).

The dealership covered the fuel pump, but wouldn't cover the cost of the tank/filler neck ($695 tank, $180 filler neck, plus labor). I was told a totally different type of tank and neck was installed on the car, and that's why it wasn't covered! GM knows the tanks/filler necks/fuel pumps are failing all over the country, but the cheapest part (fuel pump) is the only thing being covered by the recall. How do I know, they know? They installed a different tank and neck on my car!

GM has been producing cars for decades, and they still don't know what materials make for a quality gas tank? What the hell is wrong with this company? The tank just sits there and holds fuel, but the damn thing is $695! The fact their standard operating procedure for gas tank leaks is to replace with a better quality one proves they know it's a piece of crap, and dangers, but for some reason it hasn't been identified under the recall umbrella.

I hope someone important reads this complaint, because there's no way I should be shelling out nearly $1300 for something that is proven to be defective. Again the damn thing just sits there and leaks within seven years of being built, when there are cars 80 years old still utilizing original gas tanks. GM is the true definitive of engineered to fail! Maybe situations like this make them feel as though they're stimulating the economy by selling cheap, and charging maximum for repairs.

Don't forget to embrace the words of comfort offered by the service representative, when he tells you he's done the best he can for you! Please pay before you leave, sir.

Cobalt LT 2.2L

  • Automatic transmission
  • 136,000 miles

I took my car in due to a recall for the fuel pump because I had noticed a faint smell of gas coming from my car that had started in July (2014). I replaced the gas cap thinking that might of caused it but turns out that wasn't the problem. The dealer took my car in and I got a phone call at the end of the day saying that my gas tank was also cracked. They want me to pay 1k for these repairs. I reached out to GM Customer Care, and after over a week and a half was basically told what I already knew, "the resolution stands".

Gas tanks are not suppose to fail, and it's ridiculous to only be willing to fix half of the problem. Either the gas tanks are faulty as well and need to be covered in this recall or the dealer broke the tank when taking it out. This was not my fault and I am not okay with paying $1000 on something that shouldn't have failed in the first place. I expect to pay for regular maintenance, not faulty parts. If GM is so unwilling to work with the cost of the parts I will make sure to never buy another GM vehicle ever again. If GM is not willing to take the time to ensure that the parts in their cars are safe or take care of the customer when it comes up that they are not, then I am not giving them anymore money to support such a shameful company. It has become extremely apparent with the 7 total recalls on the 2007 Cobalt that GM took too many shortcuts when building these vehicles.

When I spend 13-20k on a car I expect it to be safe, durable, and drivable for the entire time I own that car. I absolutely love my Cobalt and am extremely angry now to be driving such a worthless and unsafe car.
