| My 2005 pontiac grand prix gxp would often lose speed in curves, climbing hills, or at high rates of speed. i took it to a gm dealer and was diagnosed with transmission problems. i was quoted one price for transmission, labor, and radiator replacements, but ended up paying over $4000. gwatney in north little rock, ar has a horrible service staff. they were not willing to work out a deal even after informing them i was quoted a different price. they threatened to charge me additional storage fees if i didn't pick up my car. i eventually paid, but i wrote in dispute of price on the receipt. here i am 9 months later with the same problem! go figure. *tr | |||

| Tl*the contact owns a 2005 pontiac grand prix. when the window defogger is activated and the windshield wipers are engaged, the vehicle shuts down. while driving 70 mph, the vehicle stalls and loses power. the mechanic stated that the o-ring was missing, which causes the vehicle to lose power due to lack of heat. the mechanic was unable to duplicate the failure. when the contact took her vehicle to the dealer, it was still under warranty. however, when she picked up her vehicle from the dealer, she noticed that 100 miles had been added, which put the vehicle out of warranty. the failure persists. the current mileage is 37,000 and failure mileage was 35,000. | |||

| 2005 pontiac grand prix gt sedan vin #2g2ws522851129202 purchased 12/16/2004. intermittently vehicle stalls/ loss of power in the engine. while driving the vehicle it will suddenly just loses power. you continue to press the accelerator pedal and then the engine will suddenly take back off at a great speed. this has happened while driving normally without trying to accelerate and also while trying to accelerate. the car has lost power while trying to merge in traffic. the car has lost power while trying to cross highways. the car has lost power while just driving down the road. gmc has performed the following repairs without fixing the problem. 12/30/2004 j6354-module, powertrain control-engine reprogramming. 01/24/2005 k6353-solenoid,pressure control-replaced. 02/04/2005 j6360-module, pcm/vcm-replaced. 02/14/2005 j5350-pedal,accelerator-replaced. dealership purchased from capital buick-pontiac-gmc 225-293-3500. dealership has advised that they do not know what is wrong with the car. we have been told that we have to go direct to pontiac with the problem. have been in contact with pontiac since 02/15/05. pontiac advised that they were going to research the problem and see if any other grand pri was reporting like problems. so far the only advice from pontiac is they want us to come in and take another grand prix off the lot and see if we can get this car to duplicate the same problem. this did not impress me at all. so after waiting for 2-1/2 months for pontiac to do something to fix the problem, i have decided to report this to nhtsa. *ak | |||

| Charging system failure has appeared at least 12 times on the driver's message console that i have documented. it is also accompanied by the fan blower repeatedly cutting in and out when turned on. this has happened just about every time the fan is turned on. have taken the vehicle in to have the problem checked at lambert pontiac-buick in cuyahoga falls, ohio, and they stated they ran a computer diagnostic and could not determine what the problem was, and stated there was nothing they could do about it. also, one time while accelerating it sounded as if the engine were about to cut off, but it did not. vehicle only has 3200 miles on it.*ak | |||

| 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 4500.00 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 600.00 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 *tr | |||
