Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

We also are having problems with our 2005 Buick Terraza. Its been in the shop 3 times now due to the ABS/traction/stabilizer issues...and we only had this vehicle for about 2 months. In those 2 months its been a constant headache!! we have stuck alot of money in to this already, they kept telling me the wheel bearings are out, which after 2 sets of 2 new hubs, they should be fine. I didn't even leave the dealership and the light came back on. I am a daycare provider and cannot afford to drive a vehicle that sounds like these problems they are having with this issue are life threatening...something needs to be done asap before innocent people start loosing their lives over something that long ago should have been recalled....if something happens on this end, legal action will be addressed and I suggest all of you having issues do the same!!

ABS/traction control problems with 2005 Buick Terraza. Van started applying traction control in inappropriate situations, and applying ABS braking when not needed, causing problems with stopping distance. Other than being concerning that the van may not stop when you brake causing you to bump another vehicle or worry about stopping distance for pedestrians, no actual damage has been done.

Bought a 2005 Buick terreza in Sept. 2009 39,500 mi. Approximately 31 days after purchase stability control sensor on drivers side front went bad. Making the whole front end lock up. Galpin Ford who we bought Buick from paid for lamb Chevrolet to fix the sensor Buick had 42,000. On it when went out. 30 days later same incident happened my front end locked up and on dash said stability control active stabilize stability system took back to lamb Chevrolet and at that time they said wiring was faulty making sensor go out again so they rewired the Buick this time plus replaced sensor for 2nd time. 7 months later once again front end locksup and same msg. Stability system active take back to lamb Chevrolet and same sensor for 3rd time has went bad they cant figure out why. This is a major safety issue and even if I was to pay to get fixed again its quite obvious it will go out again. It just a matter of when will it go out. While im driving down road going 65 with my 4 children thinking vehicle is repaired again and all sudden front end locks this vehicle will eventually end up killing myself or a passenger or innocent bystander. I have receipts for all repairs maintenance done on 1st complaint found online: I have had for the past seven months far outweigh the good. Neither Buick nor the dealer will do anything to compensate me for my loss of security in this vehicle. It the last and biggest problem was while driving on a major highway on a crowded Saturday afternoon, the steering completely locked up, the traction control light and service stability system lights came on, I had no ability to steer, use the gas or brake, the van kept swerving from side to side 2nd complaint: Is it ok to drive our 2005 Buick Terraza with the service stability system, ABS and traction control light on" we are planning to drive ~ 1600miles on vacation. Is it safe to drive the van with the service stability system, ABS brakes and traction control system message on computer"

While driving under normal conditions this vehicle will randomly slam on brakes, causing the driver to temporally loose control, when this happens the stability control light illuminates.

After having my car repaired & returned on 9/21/2010 my van starting repeating the same problem again on 9/24/2010. The problem is while driving at highway speed the ABS engages causing the van to jerk & lurch narrowly avoiding a wreck. Returned the van to the dealer for days, was told it was the yaw rate sensor which was replaced less than a week before. Dealer agreed that it couldn't be that but was never able to find the problem. They cleared the code and returned the van on the 10/1/2010 without any repair being done. This the third time we have had this problem with GM. There must be a design problem that needs to be fixed before someone is killed in an accident. All removed parts were retained by the dealer.

Was driving at highway speed when the ABS engaged on one side. The car jerked and lurched. My children & I were fortunate we didn't crash. Once the ABS released, the traction control engaged and then tripped out. "service stability system" message was then displayed. This happened repeatedly while awaiting the local dealer to have time work on van, I was told they were too busy to look at it even though this was an urgent problem. When they worked on the van they stated the yaw rate sensor needed replacing. Item was replaced and van returned on 9/21/2010, cost approx. $500 on 9/24/2010 same problem presented.

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.

I was driving my 2005 Terraza with about 79,000 miles on dry, smooth city streets when suddenly the car started braking on one side and, I believe, tried to control the steering. This happened three times on three different streets on the same trip across town. Each time with the message "stability control active". I drive these roads regularly and there was no reason for this to happen. I was driving slowly when at the first occurrence and was able to get the car stopped. The second time I was probably around 40 mph and because I was firmly gripping the wheel with little traffic I was able to get the van onto the shoulder and stopped. By the third time I was probably under 20 mph and terrified. I was again able to get the car stopped safely. I parked it and turned it off. It has driven fine for about 150 miles since with no recurrence. The dealer has driven it over 100 miles with their special sensor on and found nothing. There are no codes. They have checked the connectors for tightness and corrosion, again nothing suspicious. They had turned the rotors, put on new brake pads, and done other maintenance work about 50 miles before the occurrence. They do not feel this is related. They are now planning to replace the yaw sensor although they do not have evidence that this is the problem. They don't know if they will ever be able to find the problem.

I was involved in an accident and had front end damage. The air bag sensor and light are on indicating that the air bag deployed; however, it did not. We have also experienced electrical problems as well with the van. The sliding door chime comes on randomly when I we are driving. Work had to be done previously on the wiring. Occasionally I hear rattling noises from the front end of the vehicle when I drive. The van also shakes excessively when approaching speeds over 45-50 miles per hour when I put on the brakes.
