Our 2006 chevy uplander's side automatic doors open on their own as you are driving down the road. In addition, the doors will not close all of the way. We have taken the vehicle to a chevy dealer around 10 times to correct the problem and the correction will last for a few days only. Not sure what they have done to try and correct the problem but it has not worked yet. I have four young children that ride in the vehicle and I am very concerned with this problem. Not a lot of fun to be traveling down the road at 70 MPH and have the alarms start going off while the door is opening up. We have been having this problem for the last year.

Purchased a 2006 chevrolet uplander lt in august 2006. Currently have 45,000 miles and is out of warranty. Since it was purchased, we have had two recurring problems. 1)interior and exterior lights "flicker" at night to the degree that it is a driving distraction and appear to represent the driver flashing their lights. This was taken to the dealer multiple times, and only once under warranty was a part replaced which did not resolve the problem. Now dealer continues to state that they cannot replicate the problem. 2)automatic sliding doors will not open or stay closed. This is a safety hazard as they also will no longer close completely. We have taken to the dealer numerous times and it is apparent that they no longer know what to do. We have replaced several parts trying to resolve the problem. Their last resolution was to turn off the automatic door feature. The problems are identical on both doors. Several times we have been away from home and doors would not close and we could not manually close them. We asked dealer to contact gm for assistance with this issue and they advised that there is nothing they can do.

I purchased a 2006 chevy uplander in 12/06 with 20,543 miles on it. I began having problems with the steering about 3,000 miles after purchasing it. It was difficult to steer to the left and there was a grinding noise as I turned. The dealership replaced the steering column. I am having problems again with the steering, and it shakes and makes noise when I pull into parking lots. At about 30,000 miles, the rear sliding doors began to open on their own. When I put the van into reverse and begin to back out of the driveway, the doors sometimes will open. Parked in the driveway and parking lots with no one in the vehicle, the driver's rear door has opened. After I close the doors, they will immediately open, although no buttons have been pushed. Now, at 43,000 miles, the driver's rear sliding door will not close. I pushed the button inside the door as I always have to close it, as well as the overhead button, and the door would not close. Each time I pushed the button, the already open door pulled back as if still trying to open the door. When I tried to manually pull the door closed, it would not close. After 5 minutes of work, I finally got the door closed. The next day, 9/27/08, I experienced the same thing, and on this day as well, a chiming sound rang the entire trip. There is one sound for driving and a different sound for waiting at red lights. The loud ringing never stopped. When I called the dealership, they told me I was no longer under warranty, and will have to pay to have it fixed. I also discovered at 35,000 miles that my tires have worn unevenly on the outside edges of all 4 tires and need to be replaced. Also, the sway bar is in need of repair. I have children ages 2 and 4. I am concerned for their safety.

Tl*the contact owns a 2006 chevrolet uplander. Whenever the headlights are activated, the instrument panel lights will flicker and the headlights will eventually shut off. The contact also noticed that the power sliding doors will not open unless the vehicle is restarted after being turned off. The door failure occurs intermittently, but the headlight failure occurs each time they are in use. The vehicle was diagnosed by the dealer, but the failures are still occurring. The current mileage was 19,104 and failure mileage was 80.

I am still having problems with the steering shaft, power steering rack and the automatic sliding doors. The steering is stiff and there is a rubbing noise in the steering column. This has been attempted to be fixed 4 times now. The steering rack had been replaced twice, the power steering gear, the front sway bar links, and the I-shaft have been replaced. The problem still exists. The automatic sliding doors will not close properly and seem to reopen when closing. This had been attempted to be fixed 5 times. The psd assembly and rear guild roller, door position, relearn, lube and adjust was performed, new contact plates were installed. The problem still exists.
