Purchased a 2007 Buick Terraza in 2008 with 10000 miles on it. One owner. Now I know why. I am on a first name basis with the service department that tries to fix my problems. The power sliding doors are unsafe and a nightmare. Have stood in pooring rain,freezing temps,and snow trying to get a door to close. Has been in the shop at least a dozen times which isn't much fun with 4 kids and 4 carseats.have been stuck along highways and interstates with a door that wont close.not safe!!!!!! I am also on my 3rd or 4th radio in this van. Everytime it goes out the dvd player wont work so I have to take it back again to have this fixed.time is way past due for a recall on these vehicles. If anyone knows anyone looking for a slightly used vehicle I have a 2007 Terraza for sale...lol.
Sliding side doors will not close and lock, will open when driving down the road, at red light , night times lights dim and alarm goes off ,nothing lights up on dash , drains batt- in shop 4 or 5 x"s when talked to corp. Office about the danger of grandkids in back, stated due to living in florida, being wet, there is nothing they can due. So until someone gets hurt or dies, it is more or less oh well... By the way still under warr. Dealer stated the same thing... Yes I have all paperwork to this, put in shop not even one week after bought with smoking under hood.
