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.

Every Buick owner, I have talked to at about 80,000 to 100,000 miles has to replace intake manifold and bolts. This is about a $1200 job, gaskets and bolts should last a lot longer.

Instrument cluster on 2003 Buick Century doesn't work, I understand this is common on this car and very expensive to fix. I feel GM should be accountable. Also, the head gasket is blown I was told by a garage that it was the type of coolant they used and also very common on these cars. These are clearly defects in their product and they should be recalled. I have bought american cars all my life but I, M done with them, they don't stand behind their product.

2003 Buick Century 4dr - I have had for almost six years and this happened only one time. Thank god. I left walmart on side street, slowed for stop sign ahead, the engine went completely dead, lights and instruments out, I came to sudden stop. Could not restart car, doorlocks had automatically clicked, locking us inside, we could not release or open doors. We were locked inside our car. Luckily I wore cellphone. About ten minutes later, out of the blue, the power came back on all at once, lights came on. I was able to restart engine and unlock the doors. It was a rather scary situation for a few moments. I thought, "what if there had been a fire in the engine compartment?"

While driving, vehicle stalled. Consumer restarted vehicle, and drove it to the dealer for inspection. Mechanic informed consumer that the vehicle was placed on diagnostic machine, and no problem was recalled from the machine. Then, mechanic took the vehicle on a test drive. Vehicle duplicated the problem. But mechanic insisted that no solution was available at this time.
