Pontiac Grand Prix - 2000-2005

  • I have a 2000 Pontiac Grand Prix and have had the same problems with it. I bought it with 9 miles on it and have regretted it every since. My first problem was with the CD player. Every time I hit a bump in the road, it would skip. Even something as small as the reflectors that go down the middle line. I had to have it replaced 3 times. I finally gave up and had one put in from Best Buy. Little did I know that was just the beginning of my bad experiences with my Pontiac. I had a manifold leak in 2002. They found this when I took it in to have it checked because it was not accelerating correctly. The service dept told me that I had a wire that was basically chewed in half by a piece of metal rubbing against, He fixed the wire for $300. I still do not believe that was the problem. I had my manifold fixed after they put out a recall on my car for it. I then had a problem with my Check Engine Soon light coming on. When I would speed up, my car would jerk before it hit 2nd gear. I had the transmission checked and they couldn't find anything wrong with it. My husband unplugged the battery and the jerking stopped, but the light continues to come on. I have been told it might be a speed sensor, but the diagnostic checks cant find anything wrong. So... we did a tune up, replaced the O2 sensor and changed the fluids in the transmission and radiator just to be sure everything was up to date. Problems are still there. A few other problems... I have had to replace both control arms on the front end. Both tie rod ends and now am having to replace the differential on the right side. It will cost me over $350. My automatic door lock motor has gone out, my power sunroof motor has gone out and when it rains for more than a couple of hours, my windshield on the passenger side leaks water into my floor board. And I’m talking 2 and 3 inches. Not just a little. One thing you can do it call Pontiac at 1-800-PM CARES. Nice phone number dont you think?? ;) Anyway, they can note your account with all of the problems that you are having with your car. They wont fix them, but the more people that call, the more of a record they have. Oh and by the way, I am one of those people who will never buy another "American" car. My husband drives a 1987 Honda Civic and it is more reliable than my 2000. I live in Alabama and there is a Toyota, Honda and Hyundai plant all with 2 hours of my home. They may be foreign parts, but they are American made. And they will last a whole lot longer.
  • just got my 2006 GXP today. traded my 2002 GTP in, i got to say i like what they have done with the car, but winter tires are my question.
    live in Toronto, Canada snow is the issue. anyone driven in the snow with the stock tire on? and how did they handle?
  • chats1chats1 Posts: 158
    I live in the USA and only use the stock tires and have had no trouble driving in the snow, but, of course, in Canada, you get more snow. I drove uphill on six inches of hard packed snow and ice and had no problem whatsoever. You should really go to the 2006 GXP page. There are alot of discussions concerning this car there. Also, do you have the humming/hissing sound coming from the Monsoon Speaker System? I also traded in my 2002 GTP Anniversary Edition and only drove with the stock tires and had no problems driving in the snow. Good luck with your new car.
  • yep, i got the hissing noise. i figure ill take it back to the dealership and complain. if they have a fix ill post about it.
    thanks for the info on the tires. ill get winters in the late fall.

    Hi I have a 2004 pontiac grand prix gt, a couple days ago the engine light and "check gas cap" light came on, the cap was fine but I figured I would just replace it with a new one, its fine and sealed tight, how do I clear these codes off my screen and dash? Or do I have ot take it in to have it scanned and cleared, anybody know how, i have been told if i un-hook the battery it will work but will that effect the factory anti-theft system, any suggestions? Thx. tom

    Our '03 GMC Yukon (other car) had "check engine" light come on. I tightened the gas cap with a few clicks even though it seemed tight. After several short trips (about 50 miles total), the light finally went off. Owner's manual also confirms the light does not immediately go off. In the meantime, I had made an appt. with the dealer thinking something else was wrong. They "cleared code and reset system" for $88. Seems odd to me that every time someone does not get the gas cap on tight, it will cost me $88 to clear/reset. Dealer says clear/reset is necessary in order to pass I & M (local computerized pollution testing required to renew car license).
  • Tom: this just happened to me today.
    Symptom happened mid-way through a tank of gas, I stopped car, turned off, and tightened the cap (even though it was already tight).
    Started the car again, "Check Gas Gap" light came on. Cleared it using the "Enter Key." But then came on again next time I started.
    Long story short, took it into dealership, Service advisor knew of problem immediately -- grabbed the OBD code reader and cleared the codes. No issues. I'll let you know if anything else comes up.
    ARe you all cleared up now?

    Hey all.

    I just bought a 98 Grand prix from a dealership. I was wondering about the audio. The rear speakers are blown and I need to replace them. Any suggestions?

    My real question is what does this car come with for speakers? In the back I have one 6x9 and one 3". Is that normal? The speakers are not stock but they look it. Should I replace both..or am I just robbing my power?

    thanks a lot
  • gmfan007gmfan007 Posts: 77
    Our '98 GT came new with 8 speakers ... 4 on the deck shelf and 2 up front in each door. If your GP has a stock graphic equalizer and steering wheel audio controls, then it has or had the 8 speaker system.

    The rear speakers you describe sound stock to me. Ours look the same and sound pretty good for stock. You can probably find after market which are better and maybe cheaper too. Both sides should match however.
  • i just got a 97 grand prix and i have oly had it a few days and the trip computer stoped working can any one help

    I own one of those. My dad bought it brand new, and then sold it to me a couple of years ago. It has about 112,000 miles on it. The only problems we've ever had were

    1. The driver's side power window.
    2. The EGR Valve
    3. Just recently the rear passenger's side power window.

    The motor in the driver's side power window had to be replaced.

    The spring in the EGR valve has worn out and will not close the valve completely. This is not a real issue except that it keeps the engine warning light on constantly.

    I'm not sure what's wrong with the rear passenger's side power window yet. The button works, I just have to pull up on the window to get it started. I'm thinking it might come out of track on its way down. It's only been going on for like a couple of weeks though.

    A national newspaper is looking to interview consumers who have recently sold or traded a Malibu, LaCrosse, Monte Carlo, Cobalt or Grand Prix and was disappointed about its low residual value and has decided against buying another GM car because of it. Please send an e-mail to ctalati@edmunds.com no later than Friday May 5, 2006 by 2:00 PM PST/5:00 EST containing your daytime contact information and the car you sold or traded and the car your purchased next.

    Talk about biased reporting!!! Why not call for owners' experiences when trading them instead of trying to select people with bad experiences and then ask whether they bought another GM or domestic brand? Only then could you call it reporting...

    Has anyone else run into this problem? The cloth (uglycloth) upholstery on my 2004 Grand Prix GT has completely worn through to the foam pad on the door side of the driver's seat side bolster. I had noticed the area was lighter from wear, but never thought it would wear through. This at 33 months and 44,000 miles. It looks like it is where my belt would rub on the bolster when getting into the car. I only weigh 170, so I am pretty average. I have never had this sort of problem with a car before. Anyone else have a similar problem with this cloth?

    My problems sounds just like yours.Mine is the grey clothe
  • I have a 98 GTP 4 Door... totally stock. I haven't really driven it yet (just bought it from the auction and having it painted)... My friend just got a Mazdaspeed 6, I'm curious as to whether or not there is a chance of the GTP keeping up with or beating the 6. They both have 280 ft./lbs of torque, but the Mazda has 274hp to the GTP's 240. Then again, the Mazda is a 4 cyl and the GTP a 6.... So do I have any chance?
  • evandroevandro Posts: 1,108
    They are different animals. Both are supercharged, but the GTP uses a belt-driven compressor and the Mazda, an exhaust gases-driven turbo-compressor. The former is more efficient at lower RPMs than the latter. The former is more responsive to the throttle, while the latter comes after a lag, which can be extremely annoying. Both raise reliability questions.

    The Mazda is a smaller car than the GTP, but is potentially nimbler.

    The only way to tell is by driving them and making a choice about which one you like best.

    just traded in my ford escape for 05 gp So how do I get to the red led light on the dash near the window I want to change it to a blue led light thank you for any input.

    i was thinking of getting a class 2 hitch installed (but only towing sub 1000 lbs still) on my 2000 GTP sedan. i know that i'll have to be easy on the throttle to avoid possible transmission damage (i assume that this is the reason it is not recommended in the manual). so far my GP has never left me stranded and has over 100k miles. anyone else towed with their GP? am i pushing my luck? i'd appreciate any feedback,

    thanks in advance

    I have an '02 4-door SE and I have recently ran into the same problem. I have recieved instruction, however have not attempted due to the extensiveness of the procedure. First, you must remove the bottom of the seat. Next the seatbelts and the seatback. Then the side interior trim panels and finally you should be able to remove the speakers out the top. This could have been totally bypassed by screw mounting the speaker covers, but hey im no engineer.

    For the past 3 weeks I have had problems starting my car. It turns over strong but won't start. It has been towed to 3 different shops and each time for them it starts right up and they can't find the problem. Once i get it home the car doesn't start for me. Does anyone have any ideas.

    Thank you

    It's very likely to be a $20 part called a crankshaft position sensor. They tend to crack a bit, and start flaking out, especially as the engine cools or heats up. Labor will of course be the bigger part of the bill, but an honest shop should have you in and out for maybe $150. If you're mechanically inclined, visit one of the many Grand Prix clubs online and search for crankshaft position sensor - you may be able to do the job yourself.

    Hey all, question here about my dad's '98 GT. It just turned 160k miles, and simultaneously needed a new $2400 tranny. That aside, he's thinking it might be time to replace the spark plugs, but they aren't giving any trouble. Yet. He went to Advance, and they didn't have the platinum plugs that are in it, but did have the Iridium plugs for 7 bucks a pop.
    How long are the platinum's supposed to last? He's had the car 4 years and when he got it, it had 56k miles on it. 4 years and 104k miles later, he hasn't replaced any spark plugs and he's not sure if they've ever been replaced.
    Has anyone tried the Iridium plugs, and if so, how are they? Are they worth the extra dough?
    Aside from the tranny, a window switch, and the sunroof shade getting stuck back up in the roof, this car has been trouble free. That is why dad elected to get the new tranny, he doesn't want to get rid of this car anytime soon.
    Answers to my questions would be greatly appreciated.
    Thanks all!
  • alrighty, I've had the '99 for about 6 months now with 95,000 miles on it (154,000KM) and its giving me all sorts of headaches...im hoping someone has encountered similar problems so i can learn from them...

    1a - boost gauge is ALWAYS showing a reading after slowing down on highways and speeding back up multiple times. if the road is empty, no issues whatsoever -- had it up to 106 mp/h a couple days ago on a long stretch of open highway and no issues. ( sidenote - certainly didnt take long to hit 100 mph, whee! ;) )

    1b - related to the boost gauge showing a constant reading, it seems to slowly increase every time i take my foot off the pedal (yes, its showing a reading when i am NOT using the accelerator) and seems to increase when i am off the pedal. its the strangest thing, usually starts with a reading at 2 'blocks' and has increased as far as 6, very odd considering im not accelerating.

    1c - whenever im having the issue with the boost gague; i feel like im losing MAJOR power; i have had the throttle gauge sensor replaced about 5 weeks ago, didnt do a damn thing. a couple days ago when it was happening my rpms nearly hit 0. i swear i feel like the engine is just gonna seize and die, the dealership i bought it from couldnt find anything other than that sensor issue...but i think they are wrong. on occasion, when the rpms dropped like i mentioned, the car has outright stalled. once while coming down a mountain, that was fun

    its strange because driving in the city the car usually runs without a hitch, as soon as i hit the highway its a crapshoot (and a little frustrating because my girlfriend lives far away enough that i have to take the highway to see her) so this is driving me nuts, i like the car way too much to trade it in for some beater, but im frustrated when i see the rust buckets bombing around without an issue. has anyone had anything similar happen? any ideas what it could be? im so lost...im embarrased to drive my car for any long hauls! im supposed to have the road trip mobile...not my friend's lame acura integra...boo

    I had the crankshaft position sensor replaced and my car is still having this problem. Any other suggestions?

    Did you find out what was causing this? I'm having similar problems?

    :cry:
  • I just bought a Black 2005 Grand Prix. I got it reasonable and I'm wanting to make it look and possibly perform better. It has the 3.8L. I will be putting 17 inch American Racing Sniper wheels next week after I paint the disc brake calipers red. I think the chrome wheels with the red calipers and black car should look good. I'm also having Auto One put a powered moon roof in. I want to make it look like a GTP I saw a few weeks ago. It was an 04 I believe and seven grand more. I figure I can get the same look for less if I shop.
    I would like to change the rear lower bumper valance to the dual exhaust and install the stainless tips from GM.
    Any thought or suggestions would be appreciated.
    I would like to do this on a budget as I have three sons, 20,17,and 10,(money pits), living at home. Thanks. Eric
  • So this may just be an outright stupid question, but how many parts would be interchangeable from a 99 GT going into a 97 GT? Would the engine and tranny fit into the 97? At all, modifications or not? What about any other parts. Yeah i'm sure y'all would say drive the 99, but can't. Everything works, but the 99 has been passed through too many hands, and anyone that'd know anything about the car is long gone, so I can't obtain a title, so it's just sitting around collecting dust. And I don't want that if I can help it. I've got a 150000 on my 97 and it'd be really sweet to swap out some major parts if possible, and nothing beats free.
  • Chambo,
    I have had a similar problem with my 2004 Grand Prix not starting. The engine turns over but won't start. Were you able to identify the cause of the problem and any solutions? I fear it may have something to do with the fuel system.
