2004 Pontiac Grand Prix GT2 3.8LV6

Summary:

Was great, now it's okay...

Faults:

After buying it used from the dealership, for the first four years we enjoyed the car. But I have always disliked the electronic throttle system (GM should have stayed with the regular wire). At first I didn't mind it, because the transmission was always smooth. But needless to say, it causes so much downshifting, as it always wants to be at a low RPM.

So eventually my transmission started slipping at 156,000kms... I maintained this car from the inside out, and I did not expect this, since owning a 94 and 98 Grand Prix's prior to this 04. I am not sure what caused the transmission failure, but I've never had transmission problems this early in a GP. So I drove the car until I couldn't take any more of the hard shifting, and eventually got my mechanic to change the transmission. This was the biggest downfall of the car. The rebuilt transmission is okay. It's not as smooth as it once was before.

To add, the engine burns oil. Furthermore, it seems like I am changing the sway bar links constantly...

In the summer, I get "Charging system failure" when it's really hot out when idling; maybe the alternator is going out, who knows. Everything checks out okay after many tests.

Back seats are uncomfortable. They are flat. The previous Grand Prix's seats were much better. But I like the option that they fold down on this model.

The car has never left me stranded. The only major repair was the transmission. Other than that, the car is reliable.

In my opinion I feel the previous generation 97-02 GP'S were better built cars. Minus the cheap looking plastic material used in the interiors.

General Comments:

Overall, the car handles good and has nice styling. I like the dashboard and the set-up. Yes, the information display screen doesn't have the same options as the previous GP, but it does the job.

I still own the car. It is a black fully loaded Grand Prix. Leather, sunroof etc. Looks great for a 9 year old car. Fuel economy isn't great, but is decent for a V6. I am still wanting to test drive the supercharged Comp G model.

2004 Pontiac Grand Prix GT 3.8 Series III

Summary:

Reliable

Faults:

Had to get two front strut mounts replaced, control arm bushing replaced (both sides), and a wheel alignment. Also replaced both brake rotors and pads on the front, just wear & tear stuff.

General Comments:

I love these cars, great interior, although the cupholders were a little clumsy, but at least they're there.

Transmission changes gears smoothly & quickly, motor is very sufficient in power. Handling is very impressive with the sport suspension, it's actually very smooth on the road.

The car is very easy on the eyes, when it's clean, keep that once-a-year car wax on 3 times a year, and I found that the dirt & dust just rinses right off.

2004 Pontiac Grand Prix

Faults:

Headlights and all blinkers, one at a time. Coating on buttons for radio bubble and peel away.

General Comments:

I bought this car because I already owned a 2000 model. There was nothing wrong with the older one, I just wanted a new one. I even bought the same color. I have alway loved everything about this car.

Husband is 6'2", dislikes the car because of leg room.

2004 Pontiac Grand Prix GTP comp G 3.8 V6 S/C

Summary:

A flying lemon..

Faults:

It ran good for 6 months, but then the cross member, a speed sensor, and it had a recall for the electronic throttle system.

At 55k the tranny went out.

Other than that, the car has served me well...

General Comments:

This car has a lot of power. I have done some mods to it; 3 inch exhaust with headers, pulley kit, cold air intake, front mounted intercooler, stage 2 ECU.

The car is great with power, but the American car image keeps it low key.

The resale value drops like a rock, and American reliability are bad lows for this car.

My first car was a 1994 Chevrolet Camaro Z28 with the 5.7 V8, and it handled better and got better mpg. But to make a long story short, it got wrecked due to the RWD and ice on the freeway.

I don't think I'd buy another American car again.

I'm not sure why you are complaining about a blown transmission when you modified your car beyond its limits. I'm impressed that you got 55k miles out of your transmission with the upgraded pulley and ECU on the supercharger. You bought a performance sedan, not an all out sports car like your last vehicle. A rebuilt tranny should not cost you more than a thousands dollars (not installed). If you want to go fast, you have to pay to play. Good luck.
