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.

  • 435,000 miles
My vehicle's warranty is 5 years/60,000 miles. Since this week I have heard a metal scratch noise from the vehicle during driving on the road. I brought my vehicle to Ford dealership shop, it is found that rear axle seal has been damaged with oil leakage. Unfortunate, the repair is not covered by warranty because it has been 5 year, although the mileage is only 43500 miles.
