I've had my 04 GTP since May 2003. I had previously leased a 2000 GT and loved it. This piece of garbage has been in and out of the dealer's garage on nearly a monthly basis now. I've had problems with everything from constant rattling sounds to engine hesitation. The brakes have been replaced 2x and they still won't stop squealing. To say that I am completely disappointed in the car is an understatement. Yes this car has good power handling but overall the quality is just not there. I'm taking a bit of a beating but I'm trading it in for a 300C and I will never buy another Pontiac again.

Ouch..... taking a beating $$ is an understatement. Good luck, I'd stick it out if I were you.

I was going to hold off for another year or so but I couldn't stand seeing it in my garage anymore so I ordered the 300C last Tuesday. In addition to the actual problems I've had, Pontiac did a very poor job in simple design. For example they didn't put child locks on the rear doors, and did not design the rear seats to functionally fit a child's car seat. Even the little things like the cheesy pop-up door locks began to annoy me.

My '04 GP is the GTP with S/C engine. I have experienced delayed cool down whether I'm idling or driving. Over the weekend, with outside temp. approx. 90 degs, I drove with AC on Max, and noted the time. It took over 12 mins for the air to run cool, but not ice cold. After about 15-20 mins it got cooler, but again not ice cold. This was during active driving at 30-40 mph. Clearly, this is not normal performance for a modern AC unit (I even put up a silver sunscreen in front window to try and cut down on the heat).
The test vehicle was a new '04 GTP ('Special Edition'?). I didn't drive it - only idled it, but it seemed to take about same time to cool as my vehicle.
Good question about GT1/2 vs. GTP engine. Perhaps the units are different? Two different dealers couldn't give me an answer. Anyone on here have info on the specs. on the AC units of the GT vs GTP's?
Compared to my Nissan SUV - that cools down in under 5 mins, with windows closed, hot as hell in the cabin, etc. Like night and day. Have to turn it down as it gets too cold afte about 6-7 mins. Like night and day compared to the Pontiac.
That's about all I can say, but I am curious about the GT vs GTP issue, not that that would do me much good at this point. IF I had known about a difference, if indeed there is one, I definitely would have gone the GT2 route.

Jeff- I have not had any problems with the GTP other than the poor cooling issue, although I have not racked up a lot of miles yet. I do notice a bit of brake squeal, but it's not very bothersome. I am curious why you are switching to the 300C? I have seen a few on the street and they look pretty sharp, but never rode in one. I've owned the 300M and Concorde and they were both very good - with little problems (Concorde developed a ignition coil problem, but it was easily replaced under warranty). Only complaint was the cab forward design, but I see they've finally wised up and ditched it in favor of standard cabin. Good luck with the 300C and let us have a comparo when you get it. I may be right behind you! (Are you getting the V6 or hemi version?).

I suspect that modern A/C units are not as cool as freon injected ones of past years. That said, I am completely satisfied with the performance of the A/C in my GT2.
Jeff, the 300C is a beautiful car but still a first year car. Hopefully you will not have another disappointing experience. Good luck.

One more to add to the list of issues. This morning my daughter noticed water in the rear driver's side reading light and it appears to be coming in through the strip that runs along the top side of the roof.

Bob- I went with the V8 HEMI. I had taken the 300 Limited (6 cylinder) out for a test drive a few weeks back and was quite impressed. Last week I had the opportunity to drive the 300C w/ the HEMI and I was sold. I'll follow up in a few weeks after it comes in.

I've had my 2004 GP GT1 for almost a year now, and have 32000 mostly trouble-free miles on it. After a terrible experience with a 2001 Alero, I swore I'd have to go back to the imports, but the new Grand Prix has restored my faith in GM products! It's a great highway cruiser that offers alot of power, style, and features for the price, (factoring in the $$$ rebates of course). Sorry to hear of others' not-so-great experiences with their GPs. There will always be a tiny few who have a hard time with a certain car... even blessed Toyotas, Mazdas, and Hondas.

I have a GT1. I terminated my lease in a special GM early termination program on my 2000 Alero ( a piece of crap). Even when parked in a garage, the car will not cool down properly. I need to be driving at 55 mph plus in order to get and keep teh car comfortably cooled but nit as cold as Ilike it. I think part of the problem is the large front and rear window. I find that a lot of heat comes from the top of teh dash. Other than this I am very happy with the car....it has a better ride, lots more power and comfort thatn the Alero and gets better gas mileage. I also wish it was sized more like a Camry or Accord.
