What 2007 Buick Terraza owners say
Body & structure
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. …
Purchased 2007 Buick Terraza, both sliding doors have had ongoing issues. The vehicle has been in for repair multiple times per door, at one point I was told by the repair technician, as I handed him pieces of the door mounting, that it is a good thing I didn't open it one more time as the door likely would have fallen off! I have returned to my vehicle numerous times to find one of the sliding door mysteriously open. Due to ongoing nightmare of the doors opening I am careful to confirm the doors are closed and locked prior to leaving my vehicle, however they slide open on there own for no reason. The doors open mysteriously when the car is being driven, alarms ring signally doors are ajar when they are not, and/or fail to close with no confirmed obstruction. Once I am able to "close the door" and drive away the odds are 50/50 that the next bump I hit in the road that door will open. …

Rear sliding doors will not remain closed, then open while driving and continue to alarm when closed. I've taken it in for repairs three times on both doors, yet, now that my warranty is no longer in effect, I must pay out of pocket for an issue that is an obvious safety issue GM is ignoring. My grandson's car seat sits by those doors, thank god he hasn't fallen out!!! I've googled and have seen hundreds of the same complaints ignored. Why is it somebody has to die before this problem is addressed?! There are several incident dates!!!
Brakes
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.
