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.

Spark plug blown out of head. Spark plug #7 blew out 9 months ago. Now plug #8 blew out. Mechanic says it's due to poor design of aluminum head and insufficient threads. Both times, this happened while coasting at a slow speed (< 30 mph).
