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.

Fuel leak from rusted fuel lines. I am willing to allow the vehicle to be inspected as it hasn't been repaired. The fuel leak appeared to be in front of the drivers side rear wheel and it is near the exhaust which is very dangerous.

Around Dec. 22, 2021, I started smelling gas outside and inside of my car (particularly the right back seat near the gas tank). I took it to a local mechanic and he urged me to take it to the dealership for service and to not drive the car a lot because it could be dangerous. He said it was the gas tank pump and that there was a recall that I should look into. I took my car to a local dealership for service and upon inspection, they removed and replaced the fuel pump and plastic lines - they confirmed there was an issue with the gas pumps.

Strong smell of gas when driving, also strong smell of gas around car in general. Underneath the car you can see gas pouring from fuel tank, looks like it-€™s coming from top of gas tank. Whenever I park in a parking space, in my driveway or park for any period of time I always leave a puddle of gas. I just started my car and looked underneath at gas tank, there is a steady stream of fuel coming from somewhere on gas tank.

Back near the rear wheel the gas's lines are so rusted out it's because of the manufacturer put a heat shield on it and it trapped morsure and water in it and rusted the lines so bad there's barley anything left this is a known issue in Chevy Cobalt ls coupes I own a 2007 Chevy cobalt LS coupe I don't understand why there isn't a recall on all 2000-2012 Chevy cobalt models or a reimbursement for the people who bought that had to replace the gas lines because of that

The car is leaking fuel from the fuel line by the back driverside tire. This is a fire hazard as the leak is near the hot exhaust.

The fuel line was rusted causing a leak. The rusted area is by the driver side rear wheel well. The fuel line is covered by a material to shield it from the exhaust heat. The material holds moisture causing the fuel line in that area to rust and leak.

In mid 2017 I went for a drive in my 2007 Chevy Cobalt. (just over 100,000 miles). When I was approximately 4 blocks from my home the engine began sputtering and died. I was able to pull in a parking lot, put it in park and jumped out of my car. An overwhelming smell of gas was immediately noticed, as well as a huge puddle of fuel on the ground. I began to walk the 4 blocks home and saw a huge continuous trail of gasoline upon the road leading from my car ALL the way to my home! In this 4 block distance my Cobalt leaked out over 3/8ths of a tank of fuel- nearly 5-6 gallons. The fuel vapor in the air was most assuredly at a very dangerous explosive level this entire distance home. I am a self taught mechanic with many engine re-builds and repairs under my belt. Upon inspection I found that the steel fuel line had a major rupture above the driver rear wheel within the foil wrapped "joke" of a heat shield- (just above the exhaust pipe). Upon further inspection this steel fuel line was badly rusted & corroded all the way to under the driver seat. Overall the Cobalt fuel line system is a very poor design, poor quality materials, with bad design & placement. I ordered a complete new fuel & return line set and replaced all the rusty junk fuel lines. My experience with the instantaneous fuel line failure could have had a very bad ending. No warning lights or previous leaks were detected. Then there is the front suspension and front wheel bearing issues. I have installed 2 complete front suspension kits, ball joints, struts, as well as 2 wheel bearing failures- all these replaced with less than 80,000 miles on the odometer. Then there is the bad window switches, bad moon roof seal, bad wiper arm assemblies, front stereo speaker failure at 39,000 miles, on & on. A very poor quality vehicle After purchasing this Cobalt I would be very hesitant to purchase another GM product.

While at a stop I smell fuel really strong and only when there is pressure it leaks on top of gas tank where the return line cracked running down the back of the tank and onto the exhaust I see there is a recall for many other Cobalt's but not my VIN with this same issue! I am very disappointed this is a safety hazard what if somebody was to smoke by the car or they threw a cigarette out of there car and I caught on fire "??"

I have a large fuel leak and Chevy has a recall for 2008 to 2010 vehicles with rusted fuel lines, and my 2007 should be included with the rusted fuel lines recall. I think GM should reevaluate the years this is affecting. My car has under the mileage it should have and I have kept my vehicle up to date with all services! the records are at roseville Chevrolet in roseville, mn. That is where I bought my car new, as well. The fuel lines are leaking very badly. I'm in hopes they will rectify this situation.

I was driving the car and after parking it and getting out smelled a strong odor of gas. I didn't know where it was coming from so didn't think anything of it and drove the car a couple more times and each time after upon leaving the car smelled again a strong odor of gas. I decided to visually inspect the underside of the car and saw gas leaking from in front of the driver side rear tire. I quit driving the car and looked online to see if other people were having this same issue and there were. I called a couple Chevy dealerships and asked if their was a recall and was told to bring it in and they would have to inspect it to determine if it was the fuel pump assembly and if so they would fix it for free. Knowing the car was unsafe and very dangerous to drive I rented a car dolly and brought it to a Chevy dealership approximately 35 miles away. After inspection we were told it was not the fuel pump assembly but the gas lines. We had to pay $634 to have the car repaired. Repair was done in February 2020.the car had roughly 88,000 miles on it at the time problem noticed.

My 2007 supercharged Cobalt has been leaking gas like a pig. It is coming from the exposed plastic retainer clip that has rusted through my gas line and slowly rusting through my brake line now as well. This is a huge design flaw as there is definately road salt that got between the plastic clip and gas line eating away at the metals and rusting. The gas line is right above my hot exhaust and the line and repair is stupid expensive and considering all the other 3 fuel recalls on this car I believe this should be recalled as my car barely has 100, xxx miles and could potentially catch fire until I have the $900 I was quoted to fix this.

One year ago I was experiencing a fuel leak near my rear left wheel, close to where the line contacted the mounting block. I called Chevy and they said it was not their problem, and I needed to have the lines replaced before my car caught on fire, obviously. So I took the car to a local mechanic (because I am a student and couldn't afford their $1300 estimate) and they repaired it. I understand that model 2008 and 2009 Cobalts are under investigation for this exact leak. My car is a 2007 Chevrolet Cobalt and it had the exact same problem detailed in the complaint for the 2008/2009 models. I would like to impress the NHTSA to expand the investigation to the earlier models, including the 2007 Cobalt
