What owners say about the fuel/propulsion system
Verbatim from NHTSA complaints, newest first
“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”
“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]”
“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.”
“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 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.”
