Review of the 2005 Pontiac Grand Prix

  • Fast and fun to drive, the Grand Prix is still too rough around the edges to steal the hearts of import buyers.

  • Safety
  • Pros

    Strong V8 and supercharged V6, nimble handling, attractive gauges, easy-to-use controls, big trunk, fold-flat front-passenger seat.

  • Cons

    Build and materials quality still needs some work, tight backseat, noisy engine, not enough storage or cupholders.

  • What's New for 2005

    Option packages have been shuffled a bit, as have the wheel choices. New radio units include a CD/MP3 player and a DVD-based navigation system with six-disc CD changer. Remote vehicle start is now available in all models. Late in the model year a 303-horsepower V8-powered GXP joins the lineup.

Favorite car in 26 years

Vehicle: 2005 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)

Ok, i have had a lot of cars! 3 brand new ones and 25 used. This is my first Pontiac but I have had many GM's. The first time i drove it i new i was going to buy it. Sounded good, seats and interior are like a cockpit of a jet plane. The only negative is its really hard to accelerate without the front tires breaking loose. This is my favorite vehicle of all time. I would highly recommend this car to anyone that likes a sporty sedan with a great motor, great looks, great comfort, and a great exhaust sound.




Numerous problems

Vehicle: 2005 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)

bought this car new, now has 76K. Have replaced front hub, needing 2nd rear wheel speed sensor, and heads-up display is out. This car has left me stranded on the road 3 times with electrical or fuel problems that they cannot find, always in hot weather, stop and go, driving. Acts like something going thermal. Left me sitting in Nashville for a weekend the first time. Now the front end is falling apart. It will probably be gone soon! This is my 3rd. new GM and by far the highest cost to maintain. Have a '90 Baretta with 240K that has needed less!




Nice looks and powerful engine

Vehicle: 2005 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)

The looks of this car is what sold me. Beautifal car. I was looking at an 2002 Trans Am, but couldn't find one in good enough shape for the price. Bad things - at 40,000 intermediate steering shaft needed replaced, I guess this is standard as I have seen it many times in other reviews. Leaks from either the windsheild seal or from the antena are common. Water comes through the front dome light, luckily right into the cup holder. Brakes have become horrible, pads are at half wear and squeel noticeably loud, probably due to the drilled rotors. Significant rattle coming from the undercarriage, maybe exhaust? Only happens when in 'Drive', shift to neutral and the noise disappears.




Worst vehicle i've ever owned

by on
Vehicle: 2005 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)

Great power and fun to drive, however, 2 pages of repairs including 3 transmissions, tie rod ends, 3 $340 tires, this car was towed 6 times, when I basically gave it away on a trade-in it was diagnosed with another bad transmission and a bad starter!! Drove it a total of 86K. Of all the new vehicles I owned in 35 years this one is the worst. At one point the dealer said he was going to get GM to take the vehicle back, but, that TOO didn't happen. My wife actually told me "that car or me". I love my wife.




Wow, what kind of car

by on
Vehicle: 2005 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)

I get that question asked all the time. I don't know how to answer because it's so different from the base Grand Prix that I often just say "GXP" and then the person who asked shuts up and you can tell they have no clue what a GXP is.




Blue/green chrystal gxp

Vehicle: 2005 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)

My 2005 GXP is an outstanding performance sportscar. I love the output from the engine when I step on it. It feels like the rear-axle is somehow kind off "glued" when I stop and go and at a redlight if I make a normal start. Feels little bit "jerky"
