Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

During cruise on highway (I-95 in Florida) while on vacation the left rear power sliding door became unlatched and warning chimes sounded repeatedly and interior lights illuminated, this occurred several times again on this trip there was an investigation by the NHTSA in 2008 report #EA07019 which determined no defect was present which would require a recall. I beg to differ with that assessment there most certainly is a problem here, GM issued tsb #07-08-007 and #07-08-007 A-D which tells dealerships how to repair this problem. Please look into this matter again it is very unsettling to have my kids riding in the rear and having a door unlatch at highway speeds thank you for your time and consideration.

2005 Buick Terraza while doors are locked and you are driving down the road. The sliding doors decide to open all on their own. You have to stop the van and shut the doors. With the door buttons are turned off they still open just not as often.

The contact owns a 2005 Buick Terraza. The contact was driving 45 mph when both rear passenger doors opened intermittently. The failure occurred on four previous occasions. The doors will only close when they are locked, but the car alarm sounds, while driving. The vehicle was taken to the dealer, but the manufacturer was not contacted. The vehicle was not repaired, and the VIN was unknown. The failure mileage was 40,000 and the current mileage was 50,000.

I was involved in an accident and had front end damage. The air bag sensor and light are on indicating that the air bag deployed; however, it did not. We have also experienced electrical problems as well with the van. The sliding door chime comes on randomly when I we are driving. Work had to be done previously on the wiring. Occasionally I hear rattling noises from the front end of the vehicle when I drive. The van also shakes excessively when approaching speeds over 45-50 miles per hour when I put on the brakes.

Door locks will not unlock, they just click. Was able to jimmy front doors but then they would not lock. Had baby been in back seats there was no way to get them out without someone very small climbing over the front seat into the far back, very dangerous. On star could not remote open vehicle either. Drove to dealership and discovered the remote fob thought it was locking the car and started it. Dealership says they have never seen this happen before.

The driver's side power sliding door constantly would lock and unlock while driving. It would also not shut and emit a warning bell even when nothing was obstructing the door. I was told it would cost over $1000 to replace the sensor and that might not even fix it. I finally had the dealer disconnect the automatic door. So we now open and close it manually. This is a safety issue, since the lock/unlock would occur when in drive and due to the number of complaints something needs to be done.

Power sliding doors in the rear fail to close on a repeated basis, often having to try and close them 10 to 12 times. After reading about this known issue and how others vehicle owners have reported the door(s) opening on their own while driving, I felt I needed to report my malfunction with the door sensors.
