You are in the Pontiac Grand Prix
What is this discussion about?
Pontiac Grand Prix, Sedan
Mar 10, 2001 (10:19 pm)
On 2/24/01 we bought a Grand Prix SE with the 3.1 V6 engine from a Pontiac dealership in Norco, Ca. Three days later with 190 miles the engine made some unusual sounds so we drove it to the Pontiac dealership and we were told a TSB just came out in Jan 2001 to replace the 1 through 4 pistons. The service mgr called a week later to advise that a long block was ordered and his shop would be replacing the engine as the honing of the cylinder walls could not fix the problem. We contacted the PM CARES customer service line and our dealership to requeat another Grand Prix. The reps blew us off, stonewalled us from talking to anyone above them at Pontiac Motors and basically said they would fix the car and thats it... good bye and go away!!! The dealership GM said he spoke to the regional Pontiac office and was told they would fix the car and nothing more. The GM offered to sell us an extended warranty. We have no confidence in this car, the 3.1 engine and sorry to say Pontiac as a business. Having read this forum I was convinced many of you were very happy with your Pontiac vehicles. We were hoping to be one of you. This was our first Pontiac and last as we refuse to pay for this lemon. We have asked Phillips Pontiac Mazda dealership to cancel the deal and return our trade and money. Would anyone else do anything different? Any ideas how to resolve this with Pontiac and or the dealership?

karlsu99--when I originally shopped for my GTP, I was looking pretty seriously at the Acura TL (and some others)...a fine car in its own right. I had read the same "beef" about interior materials as you did. I went so far as to remove the "knobs" of both the Acura and the GP. The GPs plastic had the same "heft" and thickness as the TLs. The shapes and designs were different, but the platic seemed to be of the same quality as the TLs. I think what some object to most was that the GPs plastic didn't have the same "texture" as some others. I personally didn't have any issues with the interior of my GP, either.
psibayan--while "lemon laws" are a bit different from state-to-state, in general, GM has 3 chances to fix your engine right. If they can't, over a reasonable amount of time, then they will be subject to buying the car back via lemon laws. If they agree to give you a new engine, I would ask for a "free" GM extended, bumper-to-bumper warranty as well as a free rental car while your car is being repaired. Keep all of you communications information with the dealer and GM as back up. If the new engine fails, then you may have a case that you can take to arbitration under lemon laws in your state. The 3.1 engine has been around awhile and has seemed to be one of their "tried and true" designs. They've been using this engine for a while. My guess would be that the new one will perform quite well.

I agree with graphic guy on both counts.
I think the GP interior is more of personal thing. because of the shapes and "textures" of buttons and knobs, it may appear to have a cheaper look than other cars. But it isn't cheap, so it becomes a personal preference. My 2000 GP GT with over 17,000 has had no problems!!
Psibayan, i feel for you. I had a 2000 Monte Carlo SS bought back; however, I did give GM several tries to fix it. I don't think they will do much for you after just one try. Give the new engine a chance. If you still have concerns, you'll need to try once more, then you'll have a case(depending on state law). I think the dealer should provide and extended warranty to you, if for no other reason than to retain customer loyalty.
Lastly, has anyone tried a K & N filter. I am very interested as to whether any increased horsepower was felt!

One comment psibayan - if you had read this board as you stated, why didn't you get the 3.8 engine? It's the more reliable engine, and has much better power than the 3.1 with almost no fuel penalty.
Unfortunantly you were one of the unlucky ones that has a major defect upon purchase. This I can assure you is not the norm. My GTP has operated flawlessly since I purchased it in 9/00. I love the car even more today than I did when I got it. I would not hesitate purchasing another one.
In regards to your problem - I can tell you that many manufacturers aren't sympathetic when it comes to handling these issues. A friend of mine had 200 miles on his BMW 323i when the tranny blew, and he demanded a new car, but was only able to get his tranny replaced.
Having the engine replaced is probably the better thing - since it's *new* and potentially is not damaged from faulty pistons. From a legal aspect, they dont have to give you a new car. If they can fix it within a reasonable amount of time, they are fufilling their obligations.
From a customer service aspect, they should know better. They should at least give you some freebies for your trouble. (extended warranty). I can tell you that Pontiac Cares will always want you to take the dealer route when it comes to fixing the problem. They dont have a magic wand to make the dealer give you a new car.
If you still have problems, try calling the troubleshooter (www.troubleshooter.com)

Have you installed the cone filter yet?
You probably should go with a CAI system instead - no use getting more air if it's hot!!
Gains are typically ~ 5 hp from what I have heard.

I haven't done anything yet. Was just wondering if it is worth it from a power standpoint. Thx for the reply!

Can't tell if you have GT or GTP? Sorry, the thread's so long that I just don't have time to look back if you've mentioned it before...
I installed a CAI system from MSP (motorsport performance). It is essentially a 9" K&N with plastic housing that is insulated from Engine heat. The difference is incredible! It is generally agreed in the GTP community that this MSP CAI would add about 10hp. I believe it!!
Mar 13, 2001 (1:52 pm)
it's a GT; hence the need for some additional hp!!

GTs are great cars!
Many people have changed the CAI system, with great results. I would recommend MSP, but they're the most costly at around $260; but they do include a case for your PCM, and headsheild for the F-duct. Thrasher makes a similar one for a little less, and RAT does also (though they are having some customer service issues, I understand).
I can say that MSP fit was excellent; didn't have any problems with the install.
Doing this CAI mod along with U-bend removal would be good for about 7 hp, but that's just a guess. The stock airbox is very restrictive!

thx for the info!!
