I think with this being a known problem that it should be fixed by the Pontiac company!

This was a common complaint for 2003 Montana's. GM service manager informed me this may be part of a 'special consideration' or what I've later discovered, a 'secret warranty'. Unfortunately, the year and mileage now are not covered under anything. The only compensation offered to me to fix this $2000 problem is GM and the dealership will cover $402 (an insult) or $1000 rebate on a new or used vehicle!

My intake gasket repair was quoted out at $750, but it will cost me $2000 if the head gaskets are blown, too. I just bought this van from a used car dealership about four months ago. My pop worked for GM nearly his entire life, and he was proud to be a part of an American tradition. We've always driven GM cars and supported the company. It is hard to understand why GM would now turn their backs on customers (including their employees and their families) when they are fighting so hard to beat international competitors. It kills me to read that all of these people won't be buying from GM again due to these kinds of issues. Don't buy foreign cars, people...support our economy and keep buying American!

Complain don't make you feel better but sure lets GM kno how we all feel about Them....

We have spent almost $2000 dllrs in parts and labor to have out 2003 Montana run again, When we first found out we needed the Head Gaskets replace , we were like ok it happens, but the problem's just got even worse then just that, After the works was done, the Van was still having same issues as b4, and then came to find out it need not the head gaskets but the intake gaskets replace and let me tell you THAT I WILL NEVER AGAIN BUY A GM VEHICLE EVER EVER .....I HAVE DONE ALOT OF READING AND SEEMS GM COULD OF AT LEAST DONE SOME KINDA OF REPAIR TO HELP THIS ISSUE WITH THESE 3.4LTR MOTORS AND THE DONT SEEM TO CARE ....OH WELL U LOST ANOTHER CUSTOMER...

Just bought a 03' Montana on 12/22/08 of a used car dealer here in Fresno Ca. their name is Auto College on blackstone and shaw. They saw me go in with my family ( that's what pisses me off the most) and I told them I was looking for something to replace my aging 98' dodge grand caravan. This 03 Montana caught my eye because it was priced at $5000. I told them I was looking for something dependable for my wife and kids and they assured me thats all they sell. I bought the van and declined the warranty because it was going to cost $500 extra so I said no thanks since you guys only sell dependable cars. Today on 12/25/08 we are driving down the freeway and the temperature starts going up, my blood pressure immediately goes up (remember...dependable cars!!!) we barely get home and I pop the hood and I hear a hissing and noticed there is coolant under the intake. They knew about this problem, that's way they made sign all of this release of liability forms and disclosures. I jump on the web and get acquainted the GM 3.4 intake gasket problems, lucky me.

Like the others I developed the intakes gasket leak. I took it to a shop and they told me there was NO LEAK! 2 weeks later I was bone dry! I took it to another shop and they found the leak. The mechanic said some AF had gotten into the oil but not much. I looked up the Dex-Cool settlement and I missed the deadline to file by 2 months. I am leaning toward selling the van ASAP and let someone else deal with the future headaches
