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.

2004 Cadillac CTS Owner Comments

problem #1

CTS 8-cyl

1) I took my car in on 3/30 complaining of a leaking rear differential. I was informed nothing was wrong with the vehicle. 4/20 I was driving on the highway at normal speeds. I down shifted and heard a loud bang. The engine revved yet the car wouldn't move. The rear differential had quite literally exploded. 2) the housing to the rear differential shattered causing one of the bolts to come out and the remainder of the housing to hang at an angle. The internals of the differential looked as though a grenade had been set off in them. The passenger side rear half shaft was hanging out of the housing. 3) I'm currently locked in a fight with my local Cadillac dealership. They are trying to refuse warranty.
