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.

LeSabre 3800

Took to shop. Estimate of repair between $800 and $4000. Wife's car she's not sure she wants to fix.

The car stalled out and required towing home. Estimate based on clean or dirty repair. Clean= replacement of manifold w/ no extra changes. Dirty= replace manifold w/ possible head involvement. Pissed that GM will not acknowledge and make good on their product. If there is a fault in the engine, step up and fix. GM used to stand for quality.

LeSabre Custom 3800

  • Automatic transmission
  • 106,974 miles

Just today, for the first time ever, there was a puddle of coolant under my 2003 LeSabre 3800. The coolant appears to be coming from somewhere above the water pump. I already read a lot about intake manifold gasket failures and I would say that this seems the most likely cause at this point, but I have yet to look into it more closely. Any tips would be much appreciated; I will be fixing this myself.
