Ok, we've had this problem ever since we bought it. We have a 2006 Pontiac Montana SV6 with the passenger sliding door powered. About 1/3 the time when we close the power door, it gets almost all the way closed and then it starts dinging and opens back up. Gets annoying when we just want to leave somewhere and we mess around with the door for 2 minutes trying to get it to close. We bought the car from a GM dealer and we have a warranty on it but they can't figure it out. In my opinion, if they can't fix the door, they should replace it with a new one. If that doesn't fix it, then they should cut off that side of the car and put a new side on it. One of the two has to be bad. But I doubt that's going to fly with the dealer. They keep telling us they're "adjusting" the door to fix it but their "adjustments" never fix it. I'm pretty disgusted in the dealer and figuring if I ever want it fixed, I'll have to figure it out myself. Any ideas how to fix it? Where are the adjustments? Is this a known issue?
There's also sometimes I swear the door doesn't unlock so when we try to get it to open, it won't. Not sure if this is my imagination or if it's really not unlocking.
Also the door rattles. You'd think the rattle would be related. The dealer says the rattle and the door not closing are two separate issue... but the rattle could be because the door is loose and the looseness is causing it to not follow the tracks right and then binds... I don't know. We brought it in for the rattle once and they said they fixed it but they made it worse. Can't believe they didn't drive it before giving it back to see if their fix worked.... but what can you do. As you can tell, I'm very disgusted with the dealer but I've come to the conclusion if I want it fixed, I have to fix it.
