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.

Losing a belt means: no power steering, no water pump(no coolant), no traction control, no battery charge, and a rough ride to repair station. The belt came off due to a design flaw in the drive shaft pulley. At the very bottom of the engine the harmonic balancer(pulley) is connected to the driveshaft with a rubber insulator in between. When that rubber wears it apparently drives the pulley off alignment shredding a belt and ultimately the belt comes off. There was a design change that when you get a replacement part it eliminates this rubber insulator. It took extensive investigating to find this one, an apparent known issue.
