X2 Man,.....X2 It is nothing less then mind boogling that a $40,000 car could have such assembly and engineering problems. And I hardly drive this thing. Now nearing 6000 miles, I too have a noise started in the front end and not sure if its the Im. shaft or strut collar bearing on my aftermarket bag struts. As well I have trunk unlocking, seat memory, continual compass resetting, and Onstar phone issues. And the fuel used is stuck at 99.9 gallons. I just dont have time right now to deal with it (Wedding in Dec. and final court appereance in Jan.) and waiting for what develops. It is particularly frustrating for me because I have altered the stock suspension so far Mr Goodwretch is probably gonna tell me "your on your own" With the tremedous amount of cash buying the car and in mods, I cant trade it in but have all but resigned myself to buying another car and keeping the GXP as a Show car only/Sunday driver. I have totally lost respect for GM and the term American Made in Detroit. I was really considering buying an 08 Firebird, but the last thing I want is yet another concept vehicle that finally made it'* way to a production line in a Company where pride in work and dedicated service mean nothing any more. For those who say all Companies have a few bad cars.... save it;.... there are to many of these GXP'* falling apart and the TSB'* just keep racking up. :? I'd take a 20+ grand loss right now and sell it for 30k.
Anybody want a fresh GXP driven by a little ole grampa who never took the car over 55? Thanx for the loose connector tip on the trunk Turbocoupe, I'll check that out, and ya I had paint peeling off my front bumper that had to be sanding and repainted cranberry before the marble job as well as plastic body panels flapping in the breeze even after I let GM take a stab at fixing them.


I took a huge loss trading my GXP in this past year but I was just tired of the problem that kept developing down the line. The BMW I have now cost used what the GXP cost new but not one problem so far and much better quality and performance.

I’ve done a lot of checking, and still believe the GXP was the best car I could have purchased for the money. But only because I got it used. I paid 23,500 for mine with 7500 miles and 29 months of factory warrantee left (no sunroof though). The Acuras and BMWs don’t fall in value like the GM products do, so I couldn’t get anything in the same league for 23,500.

Anyway, I do think now is a good time to buy a GXP since they have already taken the big hit on depreciation. Looking at the values for the older Bonnevilles, it appears that values fall hard in the first 2 years, but then they do ok after that. There are still a few new ones out there popping up on Ebay for 25-27k. That is a hell of a value for a loaded sweet ride with full factory warrantee.

GM is going to have to get their act together. A 35k car has to have more than all the bells and whistles – it’* got to have high quality, or the people with 35k+ to drop on a car are not coming back.

As a side note it’* not just GXPs, a friend of mine got a really nice (and expensive) 04 turbo Volvo sedan. Super sweet ride, but it was a total lemon. Left her stranded 3 times! Check engine light was coming on, many trips to the dealer, and they could not fix it right. She took a huge loss and traded for an 05 Acura TL. No problems in 6 months.

Default Damn!

:( You guys are makin' me real nervous here. I have two Bonnevilles. The older is a 96 SSE with 135,000 on it. The car has been so reliable and run so well I went out and got a used 04 GXP (24k miles for $18,000). Looks sweet. Crimson with charcoal gray interior. Just two- 2 inch hairline scratches.

I knew it had the "clunk" in the steering wheel when I bought it and negotiated a lower price eventhough it was under factory warranty. Took it in and they fixed it. My question is "does the fix hold"?. All these other problems you are mentioning are making me really nervous. My foglamp just went out. The foglamp bulb on the SSE is a snap to change. Just looked under the GXP today and damn. I have to pull all this plastic off to get to the bulb!

Someone tell me buying this thing wasn't a mistake. Any good reviews? The thing is a dream to drive, but I still have a few months left to buy the extended warranty. From the sounds of it here I might have to do it.

Default Thanks

Thanks Jim C.

I've been a Pontiac guy since my first car (91 Grand Am) and told my wife that this was our last General. Bought the GXP b/c I can't afford the same type of goodies from Acura/Lexus/the Germans. Still Love the GXP. The styling is perfect, I love the crimson color. Hopefully I didn't get the problems that some others on this site have had.

But you are right. Just knowing the site exists is helpful. For instance, I just got the TSB for my fog lamp that burned out and it'* goin' in tomorrow.

If the fix was lubing the shaft, that lasts maybe a year to year and a half. There is a TSB on a new shaft discussed here:

http://www.bonnevilleclub.com/forum/...ic.php?t=61603

However, that says that it only goes to the 2005 model year. I don't know if there is a similar TSB for the GXPs or not.

Default dealer says they replaced it

but now it sounds a bit raspy. Was it necessary for them to also replace the tie rods? They said they were loose as well. Normal?

Two bonnies, your right it is great the site exists x2. I have got and incredible amount of help here and mod fever as well.......hmmmm $20k later....Thanx Guys for infecting Me J/K Now i'm gonna have to get it into knowing about tie rods . I go way to fast for this stuff to be happening.

And when I'm not on my soapbox I do love my GXP. The Styling and performance are why I bought it and with my mods, it'* a head turner everywhere I go. I would never part with it but it justs gets so aggravating for all the nickel / dime stuff that happens and alot of quality comprised for a car of it'* class. I know I aggravate alot of people here who have older more better built Bonnies, but they havent been to the Dealer countless times after sinking the kind of cash some of us have for these GXP'*.I am a diehard Bonnie fan but what a cost.

I had a long stint of research before buying the car, but oddly never came across this site till now. My big concern was the engine quality. I've read alot that the N* is great, reliable and low maintenance (but I've been wrong before). I was considering a Grand Prix GXP until I found out that the variable displacement technology was leased or something from Chysler. Don't trust it.

Probably the best thing about the GXP is the N* LD8. It'* reliability is well documented back to it'* inception in '94. It'* all aluminun engine can go 9-12000k miles before oil changing. The original oil monitors were set to the 12k mark and backed off to 9k. Not sure where the monitor is set by Pontiac when they got the engine. But after I changed to synthetic at 1k and having 5k more on it now, my monitor says 45% so I assume it is still at the Caddy 9k mark. The stock plugs are 90k wear rated and proven. Head bolts have been known to pop at 100k and beyond but a new casting process may or may not have cleared that issue up. I've seen conflicting reports and opinions. I feel it'* one of the best engineered engines out there. And I have pounded mine with 120 pounds of nitrous oxide now used with a 75Hp nitrous / 100Hp gas jet combo in place. And hasnt affected the motor as of yet. It runs stronger today than ever and the engine seems to loosen up for the good and run stronger as I go along. Even have hit the rev limiter more times than I care to admit.
