I began smelling fuel, especially parked on an incline. I filled up my gas tank, and witnessed loosing over 1/2 a tank of gas! I am terrified to put more than 5 gallons of gas now. Anytime I put any amount of gasoline in, the fumes are very strong inside as well as outside of my vehicle. The engine light is on and I cannot even get this car inspected since I live in north texas (denton). I took it to the dealer who said there are no recalls! the estimate to repair was 1100. 00 which is more than 25% of it's value. They said it does not have a recall. I bought the car and live in texas. So far I have had the steering assembly replaced (recall) as well as the windshield (not a recall but covered under warranty. I am so terrified of dying in this car and no one wants to fix it for under 1100. 00!.

The contact owns a 2007 Chevrolet Cobalt. When the contact started the vehicle, a strong odor of fuel emitted inside and outside of the vehicle. In addition, a significant amount of fuel leaked onto the ground. The vehicle was taken to an authorized dealer where they stated the fuel tank would need to be removed in order to perform a diagnostic test. The failure was not diagnosed or repaired. The contact drove the vehicle to his residence for an inspection and detected the inexpensive plastic lines cracked on the fuel tank module. Nhtsa recall campaign id number 09v419000 (fuel system, gasoline: delivery: fuel pump) was related to the defect. The VIN was not included in the recall. The vehicle was not repaired. The manufacturer was not made aware of the defect. The approximate failure mileage was 72,000.

A hose from the fuel tank to the evap canister, came off allowing explosive gasoline vapors to enter the air. This hose is pressed on with no clamp holding the hose in place on the fuel tank. There is a positive lock on the evap canister side of the hose, but nothing holding the hose to the fuel tank. The new fuel tank, (tank and hose one item), also has no clamp at the fuel tank. In addition to allowing explosive vapors into the air, the cost of the repair is huge. The tank assembly, (the hose and fuel tank are one item), is $500, plus installation. Chevy and gm were notified and I was told, "the parts are off the vehicle and nothing will be done about this. " to find this defect, the parts , (tank), must be removed from the vehicle. The car has 45000 miles and has never been in a crash or had any damage to it. This hose has no tension on it, just the lack of a clamp allowing it to come loose. The gasoline vapors escaping from the tank in an enclosed area, like a garage, could lead to an explosion and fire, (I'm a retired firefighter). Damage to the environment by escaping gasoline vapors also occurs, (that's why the hose is there in the first place). This negligence in the design on the part of gm could be corrected with a simple low cost clamp on the hose. This defect causes the consumer to spend a large amount of money needlessly, exposes the environment to gasoline vapor damage and could potentially explode, killing someone. Please look into this issue.
