60K Miles, Replace both front wheel hub assemblies. 2 weeks later the traction Control, ABS and Service Stability System Waring light come on. Get it back to shop and they run diagnostics ($79) on the ABS. They say I need a new Drivers side front Assembly, that we probably got a bad part. After scouring the web I find that this is a very common problem for Buick Terraza's. At what point does Buick say, Hey, we need to recall these parts because they are defective? Edmunds.com even posts that this is a know issue in the 2005 Terraza. http://www.edmunds.com/buick/terraza/2005/reliability.html I'm going to take the steps to resolve this issue, and will post here as I take the steps to repair it. Does anybody have more in-site on this issue? Where does one file a complaint with Buick?

Don't know if you still own the car or not. But complaints about any safety or repair issue for any model car can be submitted at "safecar.gov" You'll find there are several issues with the Buick Terraza as you already have discovered. Hope this info helps.
