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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Terraza 6-cyl

  • Automatic transmission

I have a 2005 Buick Terraza with 20,000 miles on it. Recently when the temp has got cold (30 degrees) the service stability and the service traction lights have came on. After I drive the van, the next time I start the van the lights are usually gone but then when I have been driving straight on a dry road at about 45 mph or so and hit a bump the van would pull, decelerate and swerve for a few seconds and the service stability light would come on. This has happened 4 times. I took it to the dealer and they found 5 codes but they say they can't help them figure what is wrong and all they can do is drive my van around until it does it again and hope they get a code that will help them. The codes were C0253/C0870/C0460/C0196/C0187. I found other people on line who had similar problems with these vehicles and printed suggestions for the dealer to check(steering wheel sensor and frayed wires). The dealer then found a green and blue wire from the forward engine harness routed from the ebcm underneath the inlet air box were completely rubbed through. They rubbed against the transmission bolt. Hopefully this will fix the problem. I guess you got to give some dealers help finding the problem with your vehicle. This is could be a problem with these type of GM vans and it could be very dangerous depending on what wires are frayed and when they malfunction the stable trak system could throw the van out of control which could lead to a deadly accident.
