Replying to: scully504 (Jul 07, 2007 4:47 am) Question. How many drivers on your van? If you have two drivers,and each driver has their own key, the Terraza will remember each driver. My wife is driver 1 and I am driver 2. If my wife has been driving and then I drive the van, there is a black out of the radio at first as the computer recognizes me as driver 2 and then starts playing my last radio station or CD or DVD. It took me a while to figure this out, but its a nice feature as I my wife doesn't ask me "did you change my radio stations? Replies to this message: scully504 (Aug 31, 2007 6:06 am)

It had been dinging at us like it was open even though it was fully closed. They had to replace a bunch of stuff in the mechanism and sensors. Also, we told them about the radio and they ended up replacing it. They also fixed the horn because I had the problem with it being hard to push.   Thanks for the input though!

We have also had problems and have had the system serviced twice. I'm not sure what GM did but it was all under warranty. Our problems were not as serious, the whole stability system would stop and the require servicing message would come on after even a minor slippage in rain or snow. In general, this stability system does not seem to work at all as the brochure or owners manual state, it has been disappointing since day one. Replies to this message: kcorey (Nov 13, 2007 1:06 pm)

Replying to: dave_justdave (Nov 13, 2007 12:18 pm) 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.

Replying to: scully504 (May 25, 2007 11:07 am) 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!

Replying to: mkauz52 (Jan 20, 2008 3:59 pm) 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.
