Here's a little update about the Stability Control System malfunction that may help. (First off, I no longer have the Terraza...the lease was just about up and I turned it in on an Enclave.) When the car had about 30,000 miles on it, I replaced the tires (4 used tires, all Goodyear) and had the 2 front tires balanced. The tire dealer where I bought the tires from advised me that judging by the wear on the original tires, the car appeared to be out of alignment and the rear shocks may be worn.(This is not unusual in New york City). (I had the alignment checked at about 25,000 miles...not by a GM dealer...it was put back to factory specs.) Both of these conditions would have caused premature tire wear, and possibly the Stability Control System light to come on. After I had the "new" tires installed, the light did not come on again and the car drove and rode as smoothly as it did when it was new. I did not re-align the front end nor did I replace the shocks as I turned in the car with 35,400 miles on it.
If I had kept the car, I would have performed both of these as I now feel both of these conditions were contributing to the malfunction.

I am currently having the exact same problem and not under warranty anymore. Please tell me what they finally had to do because so far I am in $500 (replacing the sensor) and that didn't fix the problem. Tuesday will be the 11th time in the shop.
Whoa is me!

I'll try my best...here goes.
First, get a good alignment. If your local Buick dealer can do it, good! It should run about $80. Then, have you rotated the tires? Check for uneven wear. While the car is having the alignment, check the shocks...front and rear. (Remember that the shocks not only provide a smooth ride, they also keep the tires firmly on the road). I found that the Stability Control System light only came on within a mile of a cold start, and usually as I entered a highway and started to accelerate, at about 50 MPH. If it was a problem with rough handling (like the car was getting a flat tire), I pullled over, shut off the engine for a minute or two, started up again, and all was well.
The biggest problems seemed to happen when the tires were wearing down. (The original equiptment tires...Goodyear "Infinity"(or "Integrity")...were lousy. Before I turned my car in, I put on Goodyear "Eagle" (or "Double Eagle") tires...used! After that, I never had a problem until I got rid of it, at 35,400 miles.
Good luck, I hope this helps.
