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.

GM made their intake manifolds out of a plastic resin on the Buick 3800 V6 engine. They routed the egr valve through it which causes a heat build up that wraps the intake manifold allowing coolant to go into the engine. My repair bill was $803.76 plus one starter $189 that broke when the engine siezed. From reading on the internet this is a common problem with the engines with the plastic manifold. The dealer that fixed my car aid yes it was a design problem and that he had another car of the same make and model as mine in the same morning as mine. Same problem and that he had one the week before. In my case the engine did not lock up as I as going down the highway but this could be a dangerous problem for someone going down the highway and thier engine locks up.

Vehicle at stop light when engine check light came on and remained. Was idling roughly when pulling into parking lot, and then vehicle died. Took vehicle to dealership, and was informed that upper plentium manifold had cracked and was leaking fluid onto engine. This caused plugs to be flooded. Plugs were pulled and cleaned.

Dealership advised intake manifold was cracked and starter was bad. I had just parked this vehicle two hours prior to attempting to start it again and it would not crank. I question why they are allowed to use a plastic intake manifold as this is an area that gets very hot at times. I used to be a mechanic for several years and think that Buick made an error by producing engines with plastic manifolds. I have purchased new Buick on and off for the past 35 years and this is the first problem I have ever had with an engine. Referenced in EA02-030
