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.

2005 Buick Terraza Owner Comments

problem #7

Dec 182004


  • 2,500 miles


The contact owns a 2005 Buick Terraza. The contact stated that the automatic sliding door does not close properly, which causes it to sporadically open while driving at any speed. He took the vehicle to the dealer and a technician reprogrammed the door. Five to six months later, the failure recurred. The contact took the vehicle back to the dealer and they realigned the door. Months later, the door failed again. Since the first failure, he has taken the vehicle to the dealer seven times regarding the door failure. On each occasion, the engineers have failed to successfully remedy the failure. The manufacturer did not provide any assistance. The failure mileage was 2,500 and current mileage was 81,204.

Sliding driver's side rear door opened while I was fueling the car. My wife pushed the open door button. A very dangerous situation developed as the sliding door slid backwards toward the gasoline hose. I jammed the door with my body and attempted to press the door button but the door kept trying to slide back. I squeezed the handle and yanked the hose out of the gas tank filler. I splashed quite a bit of gas on the side of the car. There should be some safety switch that would prevent the sliding door from operating when the gas tank door is open. My wife was disoriented at the time because of a diabetic sugar low and felt she needed air. I had visions of the sliding door striking the gas hose and starting a fire. The door has a safety switch that prevents it from closing if an object is in the way. But there is nothing to prevent the door from opening even when it is held or strikes something.

: the contact stated the headlights flickered when the vehicle was driven 0-60 mph. When the vehicle was taken to the sales/service dealer, the problem could not be recreated. The voltage regulator was replaced, but the problem continued. The lights failed to remain bright enough to see well at night. The computer programming was reflashed. The vehicle also had an ongoing issue with the starter, sliding door opening by itself when the vehicle was parked or while idling in park. On one occasion, the child passenger fell out of the vehicle when the door opened. There were no injuries sustained. There was a problem with the steering which resulted in the contact side swiping a mailbox post on the side of the road. At a later date when the vehicle was parked in the garage, the vehicle caught on fire. There were no reports taken by the police or fire department. The manufacturer was notified and the service dealer towed the vehicle back to the dealership.

While driving at night from a field trip with my daughter and her girl scout brownie troop, the stability track system went on in error and I lost control of the car. It went from 40 mph to 5 mph within a second. The steering would not work, either. Very, very scary! I contacted onstar in the car and they could not see a problem, but sent a tow truck. The dealership replaced a short-wire and said it was fixed. But could it happen again? also, my automatic doors never work properly. We bought this car for family trips and field trips, but now I'm too scared to take it on trips or field trips thinking that it will happen again on the express way like it did to other terazza owners. We leased it so I can't get rid of it. Instead I make a huge payment every month on a lemon.

: the contact stated the automatic sliding door locked by itself and would not open by the key or power controls. The vehicle was seen by a dealer for replacement of the power door lock motor. Although the door lock problem was corrected, the door rattled while driving at various speeds. The vehicle is currently awaiting further inspection by the dealer. Updated 5/10/2006 - the vehicle rolled back while on hills.

2005 Buick Terraza left sliding door would not open either electronically or manually. Door later opened while vehicle was in motion. The vehicle was taken to the dealer several times but they were unable to find the cause of the problem. They did update the sliding door module per service bulletin 05-08-64-013 but that did not correct the problem.
