I have a 2007 Buick Lacrosse CX, and I was hoping someone on here might know what I’m talking about with this issue… Every now and then (not every time I use the car, and I haven’t been able to find a pattern for when) for the last six months or so, my car’s dashboard will light up with “Service Antilock Brake System” follow by “Service Traction Control system”, then “Antilock Brakes Off” and “Traction Control System Off”. The thing is, it still drives and brakes just fine when these come on. It seems, in fact, like the ABS works BETTER once that light comes on. With winter right around the corner, I’m starting to think I’ve put off getting this repaired long enough, but I wanted to get some extra advice before I bring it to a shop I don’t know (I’ve just moved across the country about a year ago, in this very car).
Any help would be greatly appreciated; the searching I’ve done leads me to believe it has something to do with a loose wire, but I’ll be buggered if I can find it. Oh, and before I forget, I’ve checked the brake fluid and its good and full, the pads are in good shape, as are the calipers. The only other flaw with the car is that every now and then when you make a hard turn it sounds like it grinding, but I’m unable to see how that could be related.
