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.

My 2004 Chevy Trailblazer Ext oil pressure began to drop drastically when idling. The oil pressure would go from a normal level to almost zero and the vehicle would almost stall out. At first it only happened every now and then, but became more frequent. I read online and found out that a clogged oil pressure switch could be the problem so I replaced the oil pressure switch and never had a drop in oil pressure ever again.
