2007 Chevrolet Cobalt: fuel pump failure

Filed Apr 15, 2026 · Fuel system · NV

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

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)

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.

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.

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.

For the past few months a gaining smell of fuel has been smelled in the vehicle. It has been noticed that when driving, there is a "peeing" of gas out of my car from under the gas tank.

2 fuel leaks required extensive & expensive work: #1: fuel line rusted completely in areas where clamps attached fuel line to car body along driver's side-front 2 back. #2- plastic 'l'-shaped pieces connecting fuel lines to fuel pump@gas tank developed cracks. Both issues caused fuel leaks while engine running creating extreme fire/explosion hazard-especially bcuz gas leaks were difficult to detect while car in motion except for some gas fumes. Gas puddles only occur if idling in 1 place - otherwise it was all 'blowback' while moving & had the fuel line not needed replaced the l-pieces cracks may of gone unnoticed until complete failure because fumes & leaks blow away while driving... We are lucky to not have exploded cuz we smoke &/or any spark could've caused a boom!

My cobalt is not listed in the fuel pump-fuel line recalls that numerous others are listed in, yet, I've had the same problem! Also, the fuel lines are rusting through at the metal clamp sites and leaking gas too! I believe this recall needs extended to cover all vehicles developing this problem!
