What owners say about the fuel/propulsion system
Verbatim from NHTSA complaints, newest first
“The fuel line rusted causing it to leak. We discovered it when we had some exhaust work done on the car. No one other then myself and the people that have done the exhaust work. There was no warning of the issue.”
“Car has developed a fuel leak once again in the rear of the vehicle. this is the second time a fuel leak has been noted. the first time the mechanic replaced a portion of the line that had corroded and was leaking fuel near the driver rear tire. now the leak is in another section of the original pipe near the fuel tank. this is poor quality and engineering.”
“The fuel line on the left back side of the car (back drivers side) was leaking fuel when it was in parking or sitting and idling. Noted fuel smell when car started up and was idling, car was taken to independent mechanic, fuel line was broke in 2 places. It was broke close by the wheel are and the other spot was back by the exhaust”
“Fuel leak coming from the Left (Drivers Side) of the vehicle in the area of the rear wheel. There was a strong odor of fuel, Fuel was observed dripping to the ground under the vehicle in front of the Left rear wheel. This condition was observed only when the vehicle was running and in park. The condition does not seem to happen when the vehicle is off and not running. No repair has been made yet , vehicle can be inspected in its current condition. This is a severe safety concern of ignition/explosion due to a fuel leak; risk of property damage or even death. This problem has not been addressed yet to a dealer or local mechanic as of yet . Failed component has not yet been inspected by GM, Police or insurance. No warning lamps or messages were illuminated on dashboard, prior to failure, vehicle did have some difficulty starting, possibly due to this problem, but it did start.”
“Fuel line leak. My fuel line has cracked in multiple places and needs to be replaced entirely. The leak was consistent, with a constant stream leaking out when in operation and for several minutes after stopping the engine. The odor of gasoline was strong from inside of the vehicle when in operation and large puddles of gas were visible on the ground afterwards when I first noticed the issue. My repair quote is about $500 to get the line replaced entirely.”
“Body clips holding fuel line causing rusting at these points. Leaking fuel from body clip in front of driver’s side rear tire. Based on caked on debris (mud like consistency), it has been happening for a while but wasn’t leaking to driveway due to disuse of the vehicle. This has commonly happened on 2008-2010 HHRs and Cobalts too.”
