2003 Pontiac Grand Prix GT 3.8 SFI from North America


Best of the body style, and one nice car!


The original Bose head unit stopped playing CDs about 15000 miles ago, but luckily I still had the extended warranty. Took it to the dealer, they diagnosed the problem and ordered a new unit from Delco. When it came in they replaced it free of charge like I hoped.

Recently the passenger rear window has stopped working. Dread trouble-shooting that! Sun-roof sometimes has issues opening and closing, but overall it still works. That's it so far.

It is in need of new wheel hubs soon, based on noise I hear, and slop in the front wheel bearings. Figure that will be a good time for a front end rebuild (new hubs, rotors, pads, outer tie rod ends and anything else that is looking frayed).

General Comments:

The car performs great and handles equally well.

I've been running Mobile 1 10W-30 and a K&N air and oil filter since day one. It was rated for 200hp, but feels like a lot more.

Love this car!

2003 Pontiac Grand Prix GTP Supercharger 3.8 from North America


Unknown as of now


The side panel on the drivers side back door has fallen off twice due to... I don't know being built on a Friday maybe, The drivers side front is not put on right, which causes the back drivers side panel to constantly fall off!! (whenever I open the door/s they rub together).

And now I have no acceleration when I push on the gas petal. I get nothing. It's like driving a grandma car. I've had this car for 2 years and I am having problems with it already!

It's not even paid off yet!! The dealer is no help. Once I buy the car from them they don't care anymore! I'm already a customer what more do I need from them?

If my dealer can fix it at a half decent price, I may be back for a good review, however if it doesn't go through like I plan... Let's just say it takes one person to make something happen.

This car is ridiculous!


Initially, I had an issue with the passenger side window motor, the window would not respond to the switch, but I re-seated the motor harness and it took care of the problem.

Rear door panel clips wear out due to elongated rear doors. $2.95 fix if you know how to take the rear door panels off.

Had a CPS sensor (crankshaft position sensor) go out on a previous GP @ 95k miles. $140 fix.

General Comments:

I had a previous Grand Prix, but it was an SE with a 3.8L. I thought that car was fast. It cannot touch the GTP! I think the extra 40 horsepower is under-rated. I can smoke tuners, 5.0s, BM 3 series and was able to keep up (not beat) a Viper SRT-10. Keep in mind just a few minor engine mods.

This car looks great off of the lot. Throw a body kit on it and just watch the attention it attracts.

I definitely recommend checking out brake upgrades and possibly a transmission cooler if you are hard on your cars.

Do not cheap out on tires for this car! The tires for a high performance machine are just as important as the steering wheel!

I just wish I had a chance to drive mine more!!!

Keep up with a Viper? By that you mean you could still see him in the distance a mile ahead of you on a crystal clear day? Your car is fast but that's a little over the top. Viper 0-60 in 4 seconds. Your car 6.5-7 puts the Viper multiple car lengths ahead of you.

So far, this has been a good car. We haven't had it long enough to judge its reliability. It definitely handles well.
