2005 Grand Prix 11,000 miles car started to have severe hesitations and stumbling problems, took car in several times between two dealers and still the car is not right, I have spent close to 3,000 dollars and my secondary warranty has put about $4500 dollars all in repairs and the car now only has 33,000 miles on it, it has almost caused me to crash because of loosing power and not able to accelerate into traffic, GM is not helping resolve this at all they keep saying they don't know, I have been told it is the fuel pump or fuel pressure but that they are unable to prove this to warranty company so that they will replace it, so far to correct the problem my car has had the " catalytic converter replaced, mass-map-PCV replaced all plugs and wires replaced, complete engine combustion cleaning and most recent the transmission, this car has been a complete nightmare not knowing when this will act up and what will happen next, it has also had the steering system replaced under a defect, I have also paid included in the amount I have spent over $600 in diagnostic fees, they are telling me that the fuel pump could cost around 700.00-800.00 dollars because mine has the pump, filter and regulator all in one unit, please check into this as this has become such a strain on me and I am not sure where to go from here. Thank you
