Overall the Montana is a very nice van. We bought it used, 2 years, with 34000 miles in great condition. I really like the van. The size, the easiness of loading/unloading, the pep in the 6 cylinder engine is more than enough, very quick and handles wonderfully, especially for a long/extnded mini-van. We love all the electronic gadgets but have had numerous 'little' problems with several of them.
Has 220,000 miles but recently the ABS TCM lights came on. When I stop to restart the car and clear the lights, the wheels "lock up" and it will not move. Had to have it towed twice. Had to have the ABS TCM module replaced ($1200) and it worked ok until yesterday. Did the same thing and the wheels lock up. Anyone else have this problem, because my mechanics cannot figure out why. They are replacing components but not sure of the cause.
Purchased in 98. While we did experience the lovely Dex-cool challenge & intake manifold gasket problems, I have loved my van. Faced with the challenge of finding a new vehicle 11+ years later, few seem to match the bells and whistles we got on our Montana, nor the mileage for the size of the vehicle. Unfortunately, the engineers responsible for it are now likely unemployed - we didn't qualify for Cash for Clunkers due to the great mileage. Vehicle aged well, is still sound, durable, and comfortable, but starting to have small maintenance problems, prompting us to get a new vehicle. The perfect vehicle made for my family's use. Got us through the travelling years (soccer,football,camping)
I have had a few problems with my Transport as well. The Manifold gasket and the radio display being 2 of them. I have also had to replace the power window switch twice on the drivers side. Overall this van has been exceptional. It never breaks down and all problems have been caught in regular checks. I was going to drive it till it died. But it's 10 years old and not even sick!
