Fuel Leak it smells and leaks it seems to be coming from the gas tank and sometimes I get random electric failure when I'm driving I lose power steering and My brakes get stiff and hard to push down and my dash will go Off and then go crazy and show that i have no gas
I observed my mother’s 2007 Chevy Cobalt was leaking fuel near the rear tire by the fuel tank. I inspected the tank with engine off and it does not leak. Only with engine running. I lowered the tank and observed a small crack on the plastic return line on the fuel pump module. I started looking online and could not find a replacement part that was plastic. I then conducted more research and found the recall. I asked my mother and she stated she never received a recall. The recall was issued on 09-19-12. NHSTA ID#12v459000
The fuel pump failed and had began leaking profusely. The car was brought to the Chevy dealership where I was told it would be fixed under special coverage 12191. Chevy had tried an aftermarket part to fix but it would not seal properly and continued to leak. I got in contact with General Motors who said a new part had been ordered, a week later they told me there was no new part as they discontinued it. They are now saying that it isn’t their responsibility to fix the car due to its mileage even though special coverage 12191 specifically states no expiration due to mileage. They are offering me a credit towards a down payment which I do not want as I am not interested in having a new car payment, i want my car repaired or to be compensated once they total it out. This is my daily driver car and I have been without it for four months while GM shoves me around and refuses to deliver on their failed product. Please help.
Started smelling gas when driving vehicle. Found fuel leak on top of fuel tank. Took vehicle to Mesa Auto Works (480-969-1954) on [XXX] and they diagnosed a Fuel Pump Module broken and leaking fuel. Replaced unit at a cost of $730.22 with the fuel pump module costing $382.80. This defect could have resulted in a car fire and or worse. Definitely a safety issue. I have searched online and found many other complaints about this same defect. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

fuel lines starting pouring gas right at driver side rear wheel gas lines rusted with holes in them and my car only has 40 thousand miles on it and parked in a garage this could have been very bad since the gas lines are right next to the exhaust
Fuel pump inlet cracked causing massive fuel leak.
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.
Gas pours out of the top of the tank after fill up ... About an 1/8 of a tank of gas before it stops
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 ????
NHTSA ACTION NUMBER: PE20011 COMPONENTS FUEL SYSTEM, OTHER OPENED FROM: JULY 5, 2020'PRESENT FUEL LEAK AS DESCRIBED.

2007 CHEVROLET COBALT WITH 2.4L ENGINE. FUEL LINES RUSTED AND LEAKING (ODOR ONLY, NO FUEL ON GROUND) AT ONLY 33,916 MILES. DEALER WOULD NOT REPLACE AT GM'S EXPENSE. I TURNED DOWN THEIR OFFER TO REPAIR FOR $925.
GAS LEAKING NEAR THE REAR OF THE VEHICLE.;
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.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
