The 2005 buick terraza is equipped with a gm stabilitrack system, which combines anti-lock brake, traction and stability control systems. I was driving this vehicle at 60 MPH on a straight road during a dry, sunny day and fully loaded with camping gear, children, their computer games and my wife. The vehicle was pulling a small trailer. In an instant, the van lurched as the brakes engaged on their own. We lost 20 miles per hour in a second. We pitched forward in our seat belts, and the van swerved to the left into the other lane of the interstate. I steered as best I could, but it felt like suggesting a direction more than driving. Everything was mushy and the trailer wanted to keep going. We pitched left and right twice. I managed to steer to the right shoulder and stop. I breathed and pressed on the hazard lights. The kids asked what happened, and I managed to say that we only took a year off of my life, saved theirs, and ended the life of this van. A mile ahead, the interstate was restricted to one lane going each direction.

As we were driving home in may of 2014 the left front brake grabbed as if I had applied the brake,since then we have had both wheel bearings replaced lower ball joints and tie rod ends but nothing has changed. It has grabbed several times since then,this is a serious matter that should be dealt with, I refuse to let my wife drive the van especially when we have our five children with us because when this occurs it jerks the to the left towards oncoming traffic.

We were pulling into walmart parking lot and hit street bump that turn onto walmart's property and the sudden jerk made the keys pop out of the ignition while the van was in motion. The keys were on the floor but the vehicle was steel in motion. As we parked the vehicle I put the key back into the ignition like nothing ever happened. I turn the van of, then waited a few minute and started the vehicle and behold the key would surely come out. I contacted the dealer sierra chevrolet in bartlet, tn and they checked the vehicle out and said it was a bad cut in the key. That means a bump key would start the vehicle. The ignition switch is faulty, and seeing gm recall list, the buick terraza 05 should be on that list. I'm writing buick/gm with this statement and request.

While driving on a straight road at 30 miles an hour I heard a strange noise and the left front brake closed for a second which caused the steering wheel to jerk to the left. Since that first time I have had this happen many times while driving anywhere from 15 to 70 miles an hour. I have taken it to two dealers which found various codes. Apparently there is a service bulletin concerning the wiring harness because both dealers rerouted the harness several times and put a shield on it each time. I had the steering sensor replaced one time for $200 and the yaw sensor for $400. After the yaw sensor was changed the vehicle did not give me any problem for a full year. It started again so this time I pulled the fuse on the ABS brakes which gives you standard brakes and I have not had any more problems. I now have 120,000 miles. This is definitely a safety problem. If I keep both hands on the wheel I can react to the problem but I am afraid to let my wife drive the van. I like everything else about the van so I hate to get rid of it. I have driven cars with out ABS brakes all my life so I will continue to drive it this way. I feel it is safer this way than letting the brake engage on its on.

I want to report a very unusual incident that my wife and I experienced january 7, 2014 involving our 2005 buick terraza automobile. It was a scary event of which I am still trying to find the exact cause. While descending from the cocoa bridge crown, at around forty five MPH, I lightly applied the brakes to adjust to the traffic speed. When bam the left wheel lock up jerking us toward the cement rails on the left side of the bridge, then the car traction control' cut in and slowed the vehicle. Other car tires were squealing around us as they were trying to avoid hitting us. I would say the wheel lockup was one second or less and the whole incident lasted from three to five seconds. Then the car returned to normal operation with no further hint of this problem for the next forty miles. I've looked on the internet and found several reports of this same exact incident including many complaints on your system. I took the car to our local garage and they said the ABS computer system showed no faults and found no mechanical reason for this wheel to lock up. My next stop was the dealer where I bought the car twenty five miles away. Lane buick gmc checked it out and reported the same thing except the mechanic wrote 'corrected by suspension repair' which suggests that he fixed something, what ever it was. Yet I understood from the service representative they couldn't find anything to cause this unheard event. I next called buick in detroit, mi they were of little help saying if it didn't leave any code on the computer, it never happened. Then ask if I would consider buying a new car and trading this one in. Until I know what the mechanism is for this car behavior, I would never unload this problem on someone else. It is like the emperors new clothes story, no one at gmc has ever heard of the problem before.

Was driving at highway speed when the ABS engaged on one side. The car jerked and lurched. My children & I were fortunate we didn't crash. Once the ABS released, the traction control engaged and then tripped out. "service stability system" message was then displayed. This happened repeatedly while awaiting the local dealer to have time work on van, I was told they were too busy to look at it even though this was an urgent problem. When they worked on the van they stated the yaw rate sensor needed replacing. Item was replaced and van returned on 9/21/2010, cost approx. $500 on 9/24/2010 same problem presented.

After having my car repaired & returned on 9/21/2010 my van starting repeating the same problem again on 9/24/2010. The problem is while driving at highway speed the ABS engages causing the van to jerk & lurch narrowly avoiding a wreck. Returned the van to the dealer for days, was told it was the yaw rate sensor which was replaced less than a week before. Dealer agreed that it couldn't be that but was never able to find the problem. They cleared the code and returned the van on the 10/1/2010 without any repair being done. This the third time we have had this problem with gm. There must be a design problem that needs to be fixed before someone is killed in an accident. All removed parts were retained by the dealer.

After making several turns to exit a parking lot I stopped at a stop sign at an exit, proceeded to cross westbound traffic and as I neared the median to turn onto the east bound lanes my steering wheel became locked with the car in motion. I headed straight through the median across one lane of east bound traffic and partially through the second east bound lane. Heading straight toward a construction site I gave the wheel a turn to the left as hard as I could. Key ring flew into the window, regained control of vehicle. Engine cut out. Coasted to a safe place and pulled aside. Discovered the key was broken in ignition and another car key was bent approximately 40 degrees. Noticed the plastic on the steering column around my cruise lever was damaged. Realized another key became lodged into steering column behind the cruise lever locking the steering wheel. When I jerked the wheel, second key bent freed from the steering column and the ignition key broke in the ignition. Started the engine with the broken key lodged in the ignition. I drove to the dealership where key was removed. I was charged $51.50 for new key. I have all keys and key ring.
