* The driver side window fell off track (like that when I bought it used, so don't know when it happened).
* The seal in my passenger headlight; the seal around it started leaking and water was getting flooded inside the headlights, which caused the headlight to not work until I got it fixed.
* It is very room for my children.
* So far it has been pretty reliable, even with as many miles on it.
* I love the built in car-seat in the captain chair in mine. I have 3 toddlers :)
Don't expect an update in your lifetime, Pontiac Montana is discontinued.
Pontiac discontinued this model from the line-up after 2006. Rumors are that Pontiac itself may be discontinued, or GM may sell it.
