The ABS traction control is now coming on all the time. I understand this has been a big problem for Buick. They have not fixed any problems on these. Wish they would recall them for this problem as this is not safe. It comes on going down the road and makes a funny noise. This van has had so many problems that it should be recalled.

2007 Buick Terraza. Stability system/traction control/ABS causes front brakes to engage without warning. This has occurred no less that 25 times. Speed at time of incident has been from 10 to 55 mph. Ratcheting sound occurs (same as when traction control applies in slippery conditions); front tips down as left brake applies; vehicle pulls hard to the left. The only way I can drive is to pull the fuse, leaving ABS, tc, and ss off. Dealer has tried to fix, GM customer service became involved briefly, but I still drive without major safety features, or take my chances on abrupt speed changes, and lane changes. Not something I enjoy on the dan ryan in Chicago, when the flow of traffic is above speed limit and Chicago drivers use 5 feet as a following distance. I have found from the internet that other GM cars have had this same problem. I cannot believe that GM has never investigated this. I really like the car, but random braking surprises are disturbing.

We have a 2007 Buick Terraza cx with 11,000 miles, which was our worst mistake. It was a program vehicle. We have continually had problems with the automatic door malfunctioning. It has been taken apart and everything replaced and still it does not want to shut. The service traction light comes on along with the pump at a time when it wants to. Usually when the dealer is closed. Then it goes off without throwing any codes. The engine is riding rough but the computer shows nothing. The gas mileage is really down. We have been in contact with BBB autoline and Illinois attorney general. There is a serious problem with this door. It is a matter of time before it decides to open while I am driving with my children. I have had it into the dealer probably over 30 times or more. The records show just when something was replaced but not when the dealer tried to fix it knowing they would not get paid. I have done my own investigation and found this has been a continual problem since 2005 in Buick and Chevrolet and others with this door. There is a major problem that needs to be addressed. Their (GM) fix is the sensors but I have had them replaced and still it does not work right. I just want GM to take it back and try to find the major problem to be able to fix all the others with this problem. This is probably falling on deaf ears like everything else we've tried to do. We live on one income while homeschooling 3 kids and taking care of a mother-in-law with alzheimers. I need a safe dependable vehicle and this one is not. Please help us.
