This is the second time I have had to replace the intake manifold gasket. First time at 85,000 and now again at 150,000. I heard there is a bulletin on these but never a recall. Otherwise it is a great car! I have a 2002 Grand Prix GTP 40th Anniversary Edition and it is in excellent condition. It has been my baby for years now, but I will be selling her off within the next year.

Had intake fixed 2 months later coolant leaking again the two new plasic rings that were replaced on the huge repair fell appart due to the poor design of GM took it back to my mechanic to repair again. I will never buy another grand prix nor a GM vehicle. GM knew about this cheep design and didnt fix the problem for the comsumer. Going to sell vehicle looking at Ford vehicle to purchase.

Yeah...intake manifold gaskets should not fail at 130k miles. Especially when this engine was well taken care of.

Sucks, seems to be a problem with gm vehicles, no help from gm. i too have the cracked intake manifold gasket.

MY CAR BROKE DOWN! I was on my way to south dakota and it started to run hot pulled off the road turned off the car and it would not start again. found out it is a leaking intake gasket that is common in the grand prix. my car is a mess. default part on GM. should be recalled in all models.I have had the vehicle for just about 4 years now and other things are also going hay wire. lemon!!!

It sucked it leaked coolant into the engine and they had to replace it twice to fix the issue, GM uses too many flippin plastic parts and crap they need to get their heads out of their asses and use different materials. This should have a recall after hearing how many people had this same issue.

Well.. Now I know where my coolant is going.
Im a DIY type of gal so I am not about to go to the dealership so they can kick me in the ass and then tell me to have a nice day. I noticed the small leak mostly when running the car but could not pin point it. I figured I would find it when I changed my oil in the next few hundred miles. Doesn't sound like a great idea. Someone, anyone please give me the DIY instructions I need to get the job done. ASAP would be great. I'll be back to let you know how the repair went and what you can do to save a little cash. Thanks!

have heard from many people about this gasket that gm used being made of plastic or partly plastic if it does not function properly is that my fault or gm's apparently its just another case of the consumer being screwed again!

I just finished doing the intake gasket set on my grand prix and i must say it went awesome! The job took me no more than two hours and was so simple to do with no instruction from anyone. The gasket set was 60.00 at partssource and only hand tools were nescessary for the task anyone could do it on there own with minimal experience gotta love domestics and especially the 3.8. This motor has been around since before i was born and it is too bad they discontinued it this year but for all those who are encountering this mahem message me and i will write a message with step by step instructions for you to do it yourself at home. Did i mention i did this in my driveway no garage and still had time to get the kids from school dont let a mechanic charge you out the ass for something i know you can do yourself, i mean my 8 year old could do it lol. PEACE-

This is the 3rd GM vehicle that I have had to deal with this problem on. And they wonder why this country is going down the toilet, they make American cars disposable. I just bought this car used for my daughter about 2 weeks ago. The motor and transmission seemed to run very smoothly, but I started smelling a very strong coolant odor, even from a couple feet away from the car. Was told the intake gasket is leaking coolant on top of the motor, which is why the smell is so strong. If not taken care of, it could eventually leak into the oil, or visa versa. It is in the shop today, with an initial price quote of $700 dollars. What a bite in the ass!

I had this same problem and luckily i let somebody from the hood look at my car, and it had the same problems as some of the other complaints such as the antifreeze leaking out and it was smoking because it was dripping on some other sh*t, and my car was running hot..if u call auto zone the gasket you need to fix it is only like $12 or something like that, no more than $20. the reason it cost me sixty dollars is because that's what the dude charged me to put it on, hell he had to take all that stuff out and he had to put it all back in..took one night and i haven't had a problem since. thank lord for the mechanics in the hood!!!

Apparently we caught the problem early enough that it didn't ruin our engine. It is very expensive keeping this car up and running!! It is a pain to get fixed and the mechanic said it would be an all day job to fix.

I was CONSTANTLY having to add coolant, and it appeared to have oil in it. My heater wouldn't work during this time, my car would run hot, and it smelt HORRIBLE... I took it to the shop ASAP to get it fixed. I had to take it twice. The second time was free considering that they didn't fix it correctly the first time.

I just got my car paid off last summer, and this is the 4th time since Jan that there has been problems. 1st problem: ignition switch replacement, 2nd problem: busted hub, 3rd problem: air intake sensor, 4th problem: gasket leak. It only has 52,000 miles and already having all these problems. The Pontiac dealer where I take it to get fixed said that almost all 2002 models have the gasket leak with the coolant, and that they are not even sure why Pontiac hasn't corrected it with a recall. I thought this car would last a long time, however with all of these problems, I am not sure.

Yet another complaint and Pontiac hasn't stepped forward to stand behind their vehicles. I found about this issue of the intake manifold gasket when I took my car in for inspection at the dealer. They told me that it would need to be replaced as there was a small leak. They quoted around $1100 to do this. The dealer also stated that this is a common problem with this make and model. I found another reliable mechanic who could do this for around $800.00. He replaced the gaskets, the water pump and changed the oil. I don't have the ticket right here to know if additional items were also done. Today, my car quit while in a drive thru and wouldn't start. It appears that it was overheating due to the initial problem. After cooling down, I checked the coolant and found sludge on the inside of my radiator cap. It appears that the problem had spread farther than originally expected. Now I am looking at possibly a new radiator, definitely a flush of the system, hoses, etc. and perhaps a fix of the cooling fan. If Pontiac would have stepped forward, this wouldn't be an issue.

I have read alot on the internet about this problem and it seems to be widespread.I don't know of a recall but would like to see one soon, if just to cover the cost of the repair. It is a good car and I hope to keep it for a long time. Currently my daughter is driving it to college and I don't need her to have a breakdown with this serious problem.

I can't understand why if 7 other people have had this complaint why hasn't Pontiac
recalled the lower intake manifold.
- Althea P., Baltimore, MD, US
This is the only recall that I did receive. Again, no idea of the mileage, why they ask that I have no idea. But engine compartment fire is a little bit more than I can handle. I don't think I want to burn up in my car. I do not understand why this is the only recall notice I've received when I have every single problem noted on this site. This is ridiculous!
Update from Sep 7, 2015: Car keeps stalling out at least 3 times a day check engine light remains on checked water everything is full of oil as reported earlier still nothing from Pontiac
