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.

2001 Buick Century Owner Comments

problem #3

Apr 092005

Century 6-cyl

  • Automatic transmission
  • 60,000 miles


The teflon scraped off, along with stumbling and hesitation. The engine was replaced. Upon the replacement of the catalytic converter, metal shavings were found in the front screen. The new catalytic converter removed all of the stumbling and hesitation. The old catalytic converter showed evidence of antifreeze and was defective at time of the new engine replacement under factory warranty. A new catalytic converter should have been installed at the time of the engine replacement. The defective engine debris and obvious head gasket leak contributed to the catalytic converter failure. General Motors should pay for replacement of their poorly diagnosed catalytic converter, place in used spark plugs and wires. General Motors would not give a 100,000 mile warranty for the new engine. The chassis mileage was 94K miles.

  • Automatic transmission
  • miles
When changing gears vehicle really feels rough. Consumer can feel transmission moving like something is broken..when in first and reverse gear the vehicle will not hold on grade at idle. The engine races and disengages itself from the transmission and thunks into gear. The engine feels funny when resuming acceleration from coast speed as though it is moving on mounts. The engine feels as if it will cut off. There is a whine from the engine compartment. The engine cabin containers are impossible to open. Steering column and casing gives slight movement during acceleration and braking. This was partially corrected by replacement of the ball joint tie rod end (right side). There are exhaust fumes being emmitted into the cabin. Possible defect with the catalytic convertor. The oil drain plug shows signs of leaking. Also, the brakes seem under powered. Consumer would like information of possible recalls on parts mentioned above, also the windshiled washer fluid disappears after filling.
