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.

  • Automatic transmission

Car would not idle after starting. Thank god it happened in driveway. Towed to dealer, and dealer replaced iac valve, and cleaned fuel system. Car had 37974 miles on it. Purchased used on 07/03/03, was certified as used car, 33750 miles. Noticed intermittent turn signal flashing when purchased. Changed bulbs, no improvement. Shouldn't a safety recall be issued instead of a tsb on the idle problem?

  • Automatic transmission

Cruise control moves gas pedal rapidly down and back up at a rate of 1 to 2 occilations per second, at times car can be felt to jerk back and forth. Dealer has made many attempts to correct the issue under warrenty but now is being told that Ford will no longer pay for repairs. I feel this may be a safety issue as I do not know when the car may accelerate out of controll.
