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.

problem #1

Dec 022008

Bonneville SE 3.8L V6

  • Automatic transmission
  • 196,000 miles

About 3 months ago my oil pressure needle dropped below 40 on my gauge & fell down into the red & my check engine light came on. We put in thicker oil, but it is now doing it again and barely stays above the 40 on the gauge, even falling while I am driving down the road & really dips when I stop at a stop light or stop sign.

My mechanic put in a new oil sending unit, but having the same problem again. Not sure if there is a fix??
