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.

Failure of hose crimp in pressurized transmission cooler line. No replacement parts availability through dealers (10) or manufacturer, is indicative of a larger problem. Other hose failures have been confirmed, by other owners of both 2006 and 2007 model years. Possibility of catastrophic hose joint failure, at high speed, with possible resulting engine compartment fire or explosion. Has been confirmed by independent ase certified mechanic. Dealer representatives confirm (unofficially) that they are aware a problem exists with this line.
