Gasoline leaking from the fuel tank ports where inlet and or outlet hoses are connected. The leak originates from the tank connection, not from any specific hose. It amounts to a gravity leak of fuel from the tank when it is full or nearly so. Chevrolet has issued special coverage #12191b to manage the safety defect presumably to avoid a NHTSA recall. My VIN number, even though it falls within the range affected and production time and geography, is said to be not included. So we have fuel leaking onto hot exhaust pipes inside an enclosed garage from a poorly designed fuel tank and fittings. Seems to be a pr and monetary exposure Chevrolet would not like to risk. But stockholders run the company now. This problem likely originated in 2016 based on reports from owners of the entire run of Cobalts. This will kill owners at some point if it hasn't already.

The fuel lines are leaking where the lines connect to the fuel pump. It is causing a significant amount of gas to saturate the top of the tank and run down the rear of the tank.

Vehicle leaks gasoline. A lot of it. Took the car to the dealer and had the fuel pump module replaced (supposedly) as part of a recall. Took the car in a second time because it was leaking a significant amount of gasoline, particularly after putting gas in the gar. According to the dealer, it is a crack in the gas tank, and the problem is not the fuel pump module. The gas tank crack could very well be related to the recalled faulty fuel pump. The dealer might be using the gas tank to explain away the fuel pump issue. They have kept my car for a couple days now and want to charge me a diagnostic fee for telling me that it is an issue not related to the recall. This is very dangerous. The leaking fuel is enough to set the car on fire. The dealer could be exploiting customers (for profit) that come in in for the fuel pump recall, although I haven't observed any clear evidence of this.

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.
Fuel tank cracked,damaged, and tampered with, stated from service department at dealer. I bought it brand new and never had any fuel system work done. Leaks large amounts of fuel on the ground and in passenger cabin, causing a odor of fuel inside the car.
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. Ive 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?.
Strong gas smell inside car and under car can see a small amount of fuel coming out of the top of the gas tank.
Gas mileage had significant decrease on highway trips. After driving >50 miles and parking car in garage, garage would smell horribly of gasoline. Upon initial investigation, gasoline was leaking from the top-end of the fuel tank in the area of the plastic supply and return lines via the fuel pump. Significant amount of leakage found on car under body. Symptoms match NHTSA campaign id number: 09v419000. Car was taken to tom gill Chevrolet for repair work where it was diagnosed to replace fuel pump assembly due to a cracked fuel supply/return line on fuel pump modular. Upon discussing with dealership, it as indicated this item was under recall but is region specific. Dealership made comments that it was regional due to cost of repair. This car was manufactured with the same components as the cars recalled in new mexico, mississippi, California, etc. It is unacceptable for the consume to bear cost of replacement due to region when it is a common problem with the Cobalt platform.
Tl-the contact owns 2009 Chevrolet Cobalt. The contact stated there was a crack in the fuel line on the fuel pump module which was mounted on top of the fuel tank. The vehicle was parked when he noticed a pool of fuel on the ground and while the engine was running the fuel was leaking on top of the tank. The vehicle was taken to a mechanic shop who inspected the vehicle and informed him the fuel pump module needed to be replace. The manufacturer was notified who stated there was no recall and they can file a complaint for the failure. The vehicle was repaired. The failure mileage was 70,000. Mw.

Fuel started leaking from above the plastic gas tank. Took the vehicle to my local car repair garage. It turned out to be a cracked supply line to the fuel pump module. It appeared to be a fatigue failure. A new gm pump assy was installed at a cost of $600. The car was purchased in oklahoma and still has oklahoma plates. Upon searching for a recall for this problem, I located the recall but gm cut it off at 19000 vehicles before mine. They must have assumed they fixed the problem, but apparently the fix did not work according to the number of complaints that are still coming in. I am glad I did not park the car in my attached garage or there might have been a fire started from the strong fumes created by the large amount of fuel being forced out of the supply tube which is under pressure from the pump. Gm will not cover this incident because the VIN # lies outside of the vehicles covered in their recall. ## VIN passed ## Chevrolet Cobalt 2007 ##.
For a little over two weeks, we have smelled gasoline around the car after driving. The odor seemed to be around the tank fill. I frequently re-tightened the cap, thinking perhaps it was loose and the fumes were coming from there, or perhaps some gas had spilled in an odd place when the tank was filled. Then, last weekend during a particularly hot week here in ohio, I opened my trunk to put the groceries in and the trunk was reeking with gas fumes! I am very glad there was not an ignition source close by, as I am not sure what would have happened! this strong smell persisted the rest of the hot weekend. At home, I left the trunk open to air it out. The weather cooled last Monday and I have not smelled gas since. Also the gas tank is now only half full. My mechanic looked at the car today and feels that the problem is likely the fuel pump, as there is evidence of leakage. The car is still running and until the leak becomes more problematic we will most likely hold off on repairs as they will be expensive. Still, with the weather getting hot again, I am nervous about driving this vehicle. The strong smell of gasoline makes me ill and uncomfortable. I can't believe it is safe to smell gasoline that strongly. I called my local gm dealer and had my VIN number checked to be sure it was not included in the existing recall for defective fuel pumps. It was not.
Had been noticing a gas smell for awhile but didn't think much of it until I was failed for inspection the other day for a fuel leak. The dealership wanted 100 dollars to fix it and anywhere from 200 to 1000 to fix it they said so I had my mechanic friend help me drop the gas tank when we discovered gas on the fuel tank to find that its leaking from the fuel pump on top of the gas tank. After some research I found that this is a problem that numerous Cobalt owners are having and actually has been recalled for only certain VIN's in certain states. I don't see why the recall would not be to all cars that gm put the faulty fuel pump in. Not only is this a very costly fix due to the amount of labor involved in getting to the fuel pump but even more so it is a very serious safety risk and I don't think that gm should be able to get away without having to honor a recall of sorts to all cars they put this faulty fuel pump in.
