I purchased the vehicle march of 2014 from sunset motors in coeur d alene, id. The following day the car died and I took it back to the dealer where they told me the fuel pump needed replaced; which they replaced. I left the dealership after the repair was completed and filled my gas tank when I began to smell a strong odor of gas. I pulled away from the pump and looked under the vehicle to see gas leaking from what appeared to be the fuel tank. I took it back to the dealership and they said that the neck of the gas tank was cracked and they would repair it. I left with the vehicle after sunset motors stated the repair was done on the gas tank. The check engine light came on the following day. The code was reading p0455 large evap leak. I have tried replacing the gas cap as recommended by autozone where I took the vehicle to have the code read. The light continued to come on over the course of months. I recently took it to aamco after my vehicle started vibrating while in idle where they informed me that the crack in the neck of the fuel tank was still apparent and fuel tank needed replaced. After doing research I have found this is a common problem for this vehicle and gm had offered to extend the warranty when research into safety was done previously which was accepted and no recall was done. Gm has stated the warranty has expired. I feel that the leak in the neck of the fuel tank is a manufactures defect as there is no known reason for a crack to happen in the fuel tank. Like I said previously I have found numerous reports of this happening to others with the same vehicle. I feel that it is a safety concern and fear the possibilities of what could happen to my vehicle with myself and young children in the vehicle until I am able to afford to replace the fuel tank. I would appreciate this being looked in to and the safety around the defect.
