You Need to Reopen the Case. Due to the FACT that GM or who made the Cobalt's, Failed to tell you that THEY PUT HEAT COIL TAPE AROUND THE GAS LINES RIGHT WHERE IT RUSTED AND GAS LEAKS. WHEN THERE COIL TAPE GETS WET WITH SALT WATER FROM THE SNOW, ITS THERE HEAT COIL WRAP THAT TRAPS AND KEEPS THE SALT WATER IN SIDE THE COIL WRAP THATS TRAPED TO THE GAS LINE.I CAN PROVE IT.I HAVE THE HEAT COIL WRAP FROM MY CAR.ITS THERE FAULT NOT THE WEATHER CONDITIONS.PERIOD.WILLING TO TAKE TO COURT WITH EVIDENCE. - Sandra H., Loveland,

My car had a fuel pump go, then within MONTHS, another. We then dealt with the SAME problem symptomatically, and was told it was the fuel pump sensor. Within the last few weeks, I am having all the same issues-including the car intermittently not starting, gasoline leaking from the vehicle, both noticably missing from the gauge (i.e 1/8 tank less than night prior), odor of gas in the car, stalling out while driving and trying to start it, but also now dripping gas from the car. A new issue popped up, which is the dash light coming up saying "check gas cap". This past Thursday, my car wouldn't start again, and has not started since. It's concerning that the Chevy Cobalt has had recalls for the same exact problems, literally thousands of complaints that mirror mine- for every model year EXCEPT the 2010. It's also interesting that they also stopped producing the Cobalt entirely in 2010 too, but considering the amount of faults and issues I've seen documented in every year model it's not a shock. I'm concerned that despite the amount of complaints that include 2010 models, they were excluded from the recall and seeing that my situation is another one that won't be covered, fixed, or made right by GM is something that doesn't make sense. I have also seen, that in 2021 an investigation was launched specifically into this exact issue with the 2010, as well. I'm carless right now, with no answers from Chevy other than that it's not part of the recall, yet it's part of the problem. Something is VERY wrong here. It's shocking they wouldn't recall a vehicle knowing it's dripping gas, pooling gas, it's such a hazard for not only anyone driving them, but anyone driving near us or even PARKED near us. Please help do something! Also I have videos of my car dripping, 2 days prior to it not starting, if there is somewhere I could send those as well.

Fuel lines are both leaking on the driver-side of the car, about halfway back along the length of the vehicle. I've sent it in for repairs, but I know I'm not the only one with this issue. The car has been driven gently and only has 52,000 miles on it.

The fuel line was leaking gasoline. It put the safety of the driver and other cars on the road as the car was leaking gasoline as it drove on the highway and city streets. The problem was confirmed by a service center and the fuel lines were replaced. No inspection by manufacturer, police etc. No warnings at all, car was starting rough and/or not starting at all.

There was a very strong gas odor in the car, then noticed a puddle of gas on the ground at driver's side rear door and tire area. No warning lamps in dashboard went on. Chevy dealer service department confirmed gas line leak due to corrosion and replaced entire feed and vapor lines and filter. Charge for repair was about $1200.

Strong fuel smell and gas on the ground (creating a fire hazard). No warning messages were displayed. Puddling of the fuel is just in front of the left rear tire. Odor was detected first; then one week later the puddle occurred. Car has been repaired by GM service; fuel and EVAP lines replaced (p/n 25999914 and 15934416). Symptom and repair seem identical to HTSA Bulletin 09226C (published July 2015).

My 2010 Cobalt has been leaking fuel from the suspected fuel/vent lines at or near the rear driver's side wheel well. There remains a constant puddle of fuel noticed every time after car has been parked. The issue was first observed by a strong odor inside the cabin of the car. The amount of fuel leaking is severe enough to significantly effect my mpg and fuel pressure. The lack of fuel pressure results in delayed starting or extended cranking of engine until enough pressure is built to start the engine. The leaking fuel is a significant fire Hazzard.

Vehicle leaks fuel from the fuel line underneath the vehicle near the left rear wheel well adjacent to the exhaust pipe and muffler in a manner in accordance with currently open USDOT/NHTSA investigation (PE 20-011). A substantial puddling of fuel occurs on the ground from fuel dripping through the subframe. This is currently still happening and is available for inspection. Severe risk of fire is apparent, a highly volatile fuel in substantial amount is leaking/exposed to a substantial heat source, and could be ignited. Problem can be reproduced. Situation has been brought to the attention of two local GM dealerships, and a complaint filed with GM Corporation (Case# 9-7117335295). Prior to this finding, a substantial fuel odor was present in the cabin.

In past two months, I smelled some gasoline fumes inside the car when starting or/and shutting the engine and the odor became stronger over time. I have looked around and under the car but I couldn't find any evidence of gasoline leak. Then on few days before September 27, 2021, I had a bit of trouble starting the engine as I had to try twice before I got the engine running. On September 27, 2021, I then found the leaking of gasoline from a fuel line under the car next to left rear wheel well. It was dripping and left puddles of gasoline on the street. I decided not to drive it now because of potential fire from drippings. Now my car is now parked on the driveway with a piece of cardboard catching the drippings.
