NHTSA complaint #10078462, filed 2004-06, 47,000 miles“Noticed that coolant had to be added even though no aparent leak or overheating on my 2000 Pontiac Montana. I was told by the dealer it was an intake manifold gasket leak and would cost $970 to fix. I found that this is a common problem on this model engine either due to the dex cool coolant or the gasket. If this sin't fixed, it could lead to being stranded or stuck in a dangerous loacation.”
NHTSA complaint #10100586, filed 2004-11, 67,500 miles“I won a 2000 Pontiac Montana and I noticed over the past year that I was loosing a little anti-freeze over time. The rate increased over the past month until the engine overheated light came on. When taken to the repair shop, they told me that the intake manifold gasket was leaking and I was loosing anti-freeze through the gasket. They also said this was a common problem for GM 3.1 and 3.4 liter engines.”
NHTSA complaint #10102662, filed 2004-12, 77,000 miles“2000 Pontiac Montana intake gasket failed...I've read all the other complaints and just wanted to add mine. I called GM and they said they did not have any complaints relative to this problem, and there was no recall either. I have never used anything but dexcool in this van, now it is going to cost me to have it fixed for following directions....now I understand why Pontiac is being dropped by GM they would not be able to pay all the repair bills if the owned up to their mistake...goodbye Pontiac!!!!!!!!”
