Strong gasoline vapors while driving and after stopping on a 2009 Cobalt, drivers's side of the car. Took the Cobalt to empire Chevrolet in huntington, NY. Complained and showed them the ntsb Cobalt fuel line investigation sheet, they said they could not fix the Cobalt under a recall, ntsb investigation or service bulletin. Took the Cobalt to my local garage who replaced two leaking fuel lines for $450, bill included as an attachment. They said they have replaced many of these over the years. This is a total joke on GM's part and complete foot dragging by the ntsb for not moving sooner. Investigating? - try doing a web search.

The fuel line under the car has rusted and corroded to the point that I am leaking a steady stream of fuel out of the line. When I started the car in my driveway, I smelled a strong smell of gas and immediately turned the car off. The car struggled to start so I knew something was wrong. When I got out of the car and looked under the drivers side of the vehicle a large puddle of fuel was found under my car with a steady drip of fuel continuing to drip from the fuel line in front of my rear drivers side tire.

I first started having trouble starting my car on 9/15/20. I was smelling a strong odor of gasoline from my car. I got out and looked at it because it had never given me trouble before. I saw the car leaking gasoline near the drivers rear tire. It was leaking very quickly. I looked it up and many people mentioned a recall for the year, make and model of my car. They all said their particular car did not qualify for the recall. I think more cars are having that problem then the company realizes. I am afraid to have the car parked on the street or to even drive it, as it always leaves a puddle of gasoline in its wake. Also the muffler has started being loud at the same time. I the complaints I read being the exact same, said the problem was corrosion in the gas line stemming from the brackets hold them up.

The vehicle has fuel leak when ever the car is running. Notice this first time when oil change was done. It drips from the fuel tank down to the driver side rear end in front of the real driver side wheel. When inquired over the internet found numerous same problem being cited by the Cobalt owners. Surprised that it has not been recalled due to the potential severe consequnce of fire hazard.

The leaks are caused by corrosion of metal fuel lines near polymer blocks that hold the lines to the body. The leaks are beneath an insulation heat shield near the exhaust pipe and muffler. The vehicle was stationary on a city street. I bought this vehicle in 2010 with about 8,000 miles on it and it's been a garage kept car. The corrosion is just on the gas lines and not so much on the body of the vehicle.

After filling my car up on 7/28/2020 my car started having issues with starting without hesitation. I took it to the shop to have my oil changed and quickly realized I was losing gas. I ended up losing my tank of gas and had to return to the shop to have my entire fuel line replaced. I noticed that I was leaking something while backing out of my driveway and could see the trail of gas on the pavement. When I took my car back to the shop it was severely leaking gas near the rear left wheel well.

Fuel leak coming from corroded fuel lines at the bend located at the driverside rear of car. The heat tape aroud the fuel lines holds moisture and salt which corroded the line. Fuel leak occurs right by the exhaust pipe. Dealership explained how much of a fire hazard this was and that it should be fixxed immediately. Fuel lines should be made of stainless to prevent corrosion and possible fire from occuring.

My Cobalt has been experiencing a fuel leak. Up until I brought it into service, it had been having issues accelerating. It would sometimes feel as though it would get stuck into a slump, where even depressing the pedal completely would only allow me to slowly accelerate up to around 45-50mph. This would then eventually get unstuck after coming to a stop, or after shutting down and restarting the vehicle. This issue had been starting to occur over the past year. Also within the past 6 months or so, the car's acceleration started becoming rather jerky. It was not a smooth transition during the acceleration and road rather rough during my commutes into town. I had attempted to flush out the fuel system with 2-3 cans of seafoam to no avail. Here recently, the vehicle began to have issues starting. For the past 2-3 weeks it would take about 4-5 seconds to start up rather than instantly, and then within the past week it began not starting at all until I toggled the key on/off multiple times to prime the fuel. It would then usually be good to go for the entire day. I have taken it to a dealership service center down the street, and they informed me this morning that it is a fuel leak. They indicated they do not currently have more information from the mechanic on the precise location besides that it is a 'fuel leak' and they indicated they did not know of any open investigation on the matter, only active recalls. I requested that they please thoroughly document the issue so that I can provide further information on this open investigation as needed. Please let me know if you would like to contact the dealership accordingly to find out further information, or you may contact me for more information as needed.

In my 2009 Chevy Cobalt, I recently noticed a very strong gas smell when getting out of my car after a short trip. Yesterday, after I backed the car out of the garage to install a new car seat for my one year old son, I noticed the smell again and noticed a large puddle of gas dripping at a pretty fast pace. After investigating, I noticed it coming from a section of rusted fuel line near rear driver side tire. After looking for recalls and service bulletins, I called a local Chevy dealer and they said the leak was not covered by any recall or service bulletin and it would cost about $850 to $950 to replace the entire fuel lines from engine to gas tank. I noticed hundreds and hundreds of similar issues documented on various automotive web chat sites describing the exact same issue in the exact same place for Cobalt's from 2006 to 2010. There is what appears to be an insulator around the lines to protect them from the exhaust pipe heat that accumulates road salt and moisture over time and corrodes the fuel line at that specific location. Needless to say this issue presented a very serious condition that could have jeopardized the lives and safety of my children as well as my wife's and my lives. My car is now useless until I can save enough money to pay for the repair.

Sometime in early February of 2018 I noticed the smell gasoline anytime I approached the driver's side door to get in the car. I also noticed the gasoline when I exited the car after driving. I took the car to the mechanic as soon as possible and I was advised the fuel lines were leaking due to rust and corrosion. I had to have the fuel line and vapor return replaced immediately due to the danger presented by leaking fuel lines. The appointment with my mechanic when the fuel lines were replaced occurred on 2/19/2018. Why am filing a complaint now? I saw an article published by the associated press published on 7/7/2020 stating the us was looking into fuel leaks in older Chevy Cobalts and Chevy hhrs. At the time the issue with my fuel lines happened, I didn't believe I had any recourse, so I took no action. After seeing the article, I wanted the NHTSA to have this information so the investigation is as accurate as possible. I can provide a receipt showing I had the fuel lines replaced if needed.
