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.

So after a failed attempt at renting a car I had to break and use my damn endeavor to travel down to Disney world. Had a great time myself but my car seemed to hate it. On our way back I noticed a sickening sweet disgusting odor and my floorboards were soaked on both sides. My girlfriend put a bag on the floorboard and it had a brown stain on it. Talked to my mechanic when I got back and realized it was the heater core. This thing is literally leaking antifreeze all over my car and you can now hear and see the flow of antifreeze sloshing around. Finally getting it fixed after $750 later. It's not really the cost of the part itself but the cost for the labor. You literally have to take apart the dash. Leave this to the pros or junk it.. I think it's time to sell or junk this piece of sh*t off the side of the earth. I'm over this damn car. I'M OVER IT!!
