My 2005 Buick Terraza had developed problems with the traction control warning light coming on warning to have it serviced. The dealer put it on his computer and I was told it was safe to drive after they replaced the traction control module. The light came on again within a week. After the light came on within a few miles the brakes automatically slammed on slowing the van considerably. It happened at least 4 more times before I was able to take it to the dealer for servicing. After several hours I was told it was probably the abs system had failed and they had to replace it. I have never heard of this problem before but wanted to bring it to your attention in case it might happened to someone else.
