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.

Car heater would not warm up. Temperature would then fluxuate between hot and cold. Took the car to the dealership, the dealership diagnosed the problem as intake manifold gasket failure. Coolant mixed in with oil in the engine. Dealership service department required to keep car overnight to fix the problem. Needed a rental car and no loaner was available. GM agreed to split the cost of the intake manifold gasket repair 50/50, but would not cover the cost of a rental car. Effect of this gasket failure at this time is unknown and effect to engine and components. Car has 68,500 miles. Original owner off car has kept up with all scheduleed maintenance.

The 2001 Buick Century was not shifting well and ran out of transmission fluid. When the reservoir for transmission fluid was refilled the fluid ran out quickly and I took the car into the local dealer to be repaired. They told me all the fluids were mixing and that if it was not fixed the antifreze and water would have leaked into the oil and blew the motor because the lower intake maniforld gasket was bad. The bill from the dealer accounts for leaking transmission fluid lines and the li manifold gasket. These were expensive repairs and the reason I decided to report them was that my son and daughter-inlaw both have new GM vehicles and have replaced the intake manifold gaskets on one of them 2 times and the other 1 time for a total of 4 intake manifold gaskets for out family. They have a 2001 and a 2002 Alero. Now my daughter is also describing what may be the same problem.

Consumer states that the vehicle would intermittently backfired and stalls upon starting. Dealer notified. The engine was replaced by the manufacturer under bulletin teflon coating failure. The starting and stalling problem reoccured after 3000 miles, but the dealer refused to honor the warranty. The water pump failed. Also, the steering column flexes when the vehicles movement was reduced.
