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.

Vibration at 50+ mph. Pulsating, vibrating when braking. Uneven wear on tires (feathering) noticed at 3,000 miles. Horn takes a lot of pressure to make it work. 2 metro Buick dealers say all above is normal and can not find anything wrong. One dealer printed 2 service bulletins to show me GM says it is normal. Headlights and interior lights dim and brighten on their own. Have had numerous oncoming cars blink their high beams at me thinking my high beams are on. I was denied in my request for a Buick official to get involved. Van is now 9 months old and only 8,000 miles because it is unbearable to drive with all that shaking.

: the contact stated the horn will not sound without applying a lot of pressure. Upon recommendation of GM, the dealership installed a redesigned kit to try and correct the problem. The kit did not correct the problem.

Buick Terraza horn only works when excessive force is applied from the heal of the hand and in the exact center of the steering wheel. ** answer required*** the dealer claimed that the problem with the horn could not be corrected. The consumer feels that the location of the temperature and compass gauges makes them impossible to read during too little or too much sunlight.

The contact tried to using the horn but most of the time could not get it to blow. Even when pressing hard on the horn it would not work. One must hit it correctly in order to get it to work properly. He has taken the vehicle to the dealer, who agreed it took a lot of force for the horn to work. The dealer had a representative look at the horn. The representative was doubtful that GMC would fix the horn. He stated it was a sensor that failed, it send a message to the steering wheel, and it was sending wrong information. When pressing the accelerator the brakes would clamp down and slow down the vehicle. This would cause the vehicle to stop while in motion to continue on. The contact stated the headlights brighten and dim on their own. The dealer replaced the alternator in order to correct the problem. The vehicle was having the same problem.

The contact stated had a technician from GM look at his car because he was having many problems with his horn. E noticed problems with the horn on or around 5-20-05. It was very hard to push. The horn. You almost have to take a hammer to get it to blow. The dash lights are also very dim. He has found several complaints on the NHTSA website about the horn not blowing. Transmission kicks into passing gear too much going up slight grades on the interstate at 65-70 mph. The contact has driven other cars on the same interstas with the same average loads and with less horsepower and they didn't kick into the passing gear as much. The tech that GM sent out, said everything was normal.

I was driving on the highway switching lanes on dry pavement, clear day, and the traction control system or the stability control system engaged causing the vehicle to rapidly decelerate and swerve to the left. It happened to my wife and she called me crying saying she did not want to drive the car. I did not take her seriously, until she went out of town and the vehicle did the same to me on the highway. This traction control or stability control system has a problem and is a major safety concern. I tried to disengage the system before driving it on the highway to take it to the dealer and it happened again. The horn is hard to push and cause the horn to make a sound. Without a horn, the car is not safe.

The consumer complained about a horn problem. The consumer to push different spots in order to get horn to blow. It did not blow where the symbols were located on the vehicle.

Caller says the horn did not work. They checked the problem on other vehicles and were waiting to hear from the manufacturer on how to fix it. Manufacturer said they will start a file on the problem. Caller said that he has to apply a great amount of force to get the horn to work and he must push the middle of the steering wheel. The dealer checked other Terraza's and found the same problem.

The consumer owns a 2005 Buick Terraza. The only the way the horn will work is by taking both of her thumbs and pressing as hard as she can to get the horn to blow in the left hand corner that is the only spot that it will work. The horn has not worked since she purchased the vehicle. She filed a complaint with GM.
