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.

The check engine soon light had come on. The vehicle looked as if it was leaking coolant, however no coolant was found leaking. When the vehicle was taken to the repair shop, they found an internal leak. This was caused by the plastic plenum intake.

On 07/21/03 my 1998 Buick Lesabre (VIN [xxx]), suddenly and without prior symptoms, began to run extremely rough and the engine stalled and was unable to be re-started. Fortunately, I was able to get off the road before the engine stalled. I am now saddled with a $2,000 repair bill  all, apparently, as a result of the failure of the plastic GM plenum. The plenumS failure caused other failures within the engine (including, but not limited to, the ignition control module and the starter). According to the mechanic that serviced the vehicle, this is not uncommon in GM vehicles that utilize the plastic plenum. I would seek restitution from General Motors for what appears to be a historical and systemic failure of this plastic plenum resulting in extraordinary engine repairs.

I purchased a '98 Buick Lesabre - from my brother-in_law, it only had 70,000 miles on it when the head gasket blew causing me to rebuild the top section of the motor--then after that was fixed and I drove the car for approximately 3 months more -- the bottom part of the engine blew--and I had to replace the complete engine not knowing what caused this problem. The car was always maintained by the dealership "boyle Buick" in bel air, md.

Car refuses to crank sometimes, wait 45 min-1 hour, then it will crank. Also, slowing down to stop and car just dies, refuses to crank, again wait 45 minutes - 1 hour and it will crank. This is happening every 2 weeks-1 month. I was told it was not firing, but could it be something to do with fuel system? dealer kept for 2 days and could find nothing wrong. Buick said they had not heard of this problem.

There was a back fire in the intake manifold, which is made of plastic and it exploded casusing the engine to catch fire. Visual damaged caused by the fire was to the fuel line, air line and wire harness. Vehicle is 4.5 years old and only has 23,000 miles on it.
