"I have owned this vehicle for six years and although it has never been unreliable. It has had break issues the entire time. Just two years the ABS distribution box had to be replaced along with rotors, calipers, brake lines, brake pads and any other piece relating to the brake system. The calipers are dealer only parts. You can find them second hand but they are still pricey. The caps for brake fluid, power steering are also dealer only parts. GM would not take my van into their garage and stated because it is out of warranty they would not hook it up to their machine to tell us what was wrong even though we would have paid. The material on the seats get stained from the water hitting them when the doors are open and it rains. GM again did not want to help even when we first bought the vehicle. I can see now why Pontiac is out of business. Anyway.. Good luck if you own this van."
Cons: "front cup holder location, rusting at rocker panel"

"I bought this van in 08 with about 75K on it. Four years later I doubled the mileage and other than brakes, tires oil changes, I have not done much to it. Now it has exhaust manifold leak and needs catalytic converter replaced. Debate begins now to replace or repair. The rocker panels below the sliding doors are rusting or I wouldn't even think about it. This has been a great van and we are not easy on vehicles. My wife drives it like a mad woman in a tank, she is on the move constantly. The cup holder design drives me nuts, they are right in front of the temp controls when you put a cup of coffee in there. Other than that, plenty of storage, seats are easy to get in and out, visibility out all the windows is great, no blind spots and the controls from the driving seat are easy to reach and it rides very nice."
"THE ONLY THING WE ARE DISAPPOINTED IN IS THAT OURS AT 78000 MILES NEEDED A NEW INTAKE GASKET (CLOSE TO A $1000.00 JOB). WE THEN FOUND OUT THE 03 AND 04 MONTANAS ARE KNOWN FOR THAT TO START LEAKING EARLY ALONG WITH THE HEAD GASKET."
