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.

Mustang 6-cyl

  • 90,050 miles
We took our 1998 6 cylinder mustang in for an oil change. It has about 90,000 miles on it. We were told that it is leaking fuel and that it is a safety hazard. We now have to spend $1000 to replace the fuel rail, both valve gaskets, valve cover gaskets and fuel injector O rings. Plus a significant amount on labor. We were told that our car/engine will catch fire, if we do not replace these parts. This is my daughter who is in college's car. How can they have such a horrible design and if we replace the parts is this going to be repeated? the other issue is that there was no warning from an engine light or anything else. The technician checked it because when he looked under the hood, he thought he smelled gas and then found the leak. We hadn't noticed a leak. My daughter could have been killed driving back to school this week.

My husband I purchased a 1998 rouch Mustang GT. The conversion kit includes side pipes, computer chip, different suspension, and some things im not sure of. I have been having problems with raw fuel smell coming into cab of car. It get's very bad. It only happens when it is 85 degrees or above. And only happens randemly. One day while driving my daughter from school, fuel smell came into cab. Daughter and I gaged. Pulled over and shut car off. Took car to dealer, they said they were waiting for new fuel line from the roush company. I was told that the rouch cars needed different fuel line then that of the manufacturer. They said they fixed the problem. Then my husband and I were going to daytona. It happened again. Pulled into dealership shut car off with windows down. Ten to fifteen minutes gone by before george nagel the service manager sat in it. He kept car do to he smell of fuel. And that is after the car sitting there airing out. He smelled it coming from the vents. They said they fixed it. Happened again. Now goerge is saying that he does not know if it was gas or emmisions that he smelled. My car know sits in my driveway, I am renting a car. I am doing lemon law. I was told by an attorney if I can not prove my case they will lean towards the manufacure. There is a serious problem with my car. I am afraid of this car. I have owned Mustangs for many years now. Thats all I have owned. I love my car. I'm afraid to drive it. But my safety is at risk. Please help me.

While traveling at 70 mph the vehicle lost power, forcing an emergency exit from the highway. The vehicle was towed to the nearest Ford dearlership and we were advised that a technical service bulletin had been issued advising dealers that there was a problem with a wax ring in the fuel system that was breaking apart and the wax pieces were lodging in the fuel pump casing the car to lose power. No recalls had been issued because we were told the cars were all still under warranty.
