The power sliding doors on this van suck! The passenger sliding door was first having problems opening (with the power on). The sevice manager said that the "contacts" were probably dirty, so he cleaned them off. Later, the problem still occurred. Took it back in and they "adjusted" the opening mechanism. After that it seemed to work fine until my wife and 4 children were driving on the interstate at highway speed, when the door that the dealer worked on SLID OPEN!!! WTF?? I informed the dealer about this, took it back in, and they actually ordered new parts this time. The door actually works now, but after a nearly tragic accident!! Now, a year later, the driver side sliding door doesn't open properly!! HATE THIS VAN!! CANNOT WAIT TO TRADE IT!! NEVER A GM AGAIN!!
