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.

Our first F150 ecoboost purchased in July 2011 was taken by Ford as a lemon. The replacement truck provided in November 2011 has the same issues. While driving in rain on a freeway our V6 ecoboost F150 truck engine starts to shudder, shake and then rapidly lose power while driving at highway speeds. Then the engine completely shuts down when accelerating. Our vehicle barely made it to the side of the road where it stopped running. After letting it sit for a few minutes the engine was restarted. Although the engine worked the truck continued to shudder and shake with limited ability to accelerate for the remainder of the 3 hour drive. Over a period of many months the problem recurred many times, almost always when driving in the rain. The problem was even worse while driving in the rain and towing a boat trailer. The problem is especially horrific when towing a trailer and driving in the mountains in the rain. The problem also occurs no matter then weather when driving through the mountains of Kentucky, Tennessee and northern Georgia. The truck is totally undependable. Although the truck has been in the dealership for repairs the problem is not fixed! on top of the loss of power, a life threatening situation when driving in traffic on any road especially a freeway, the miles per gallon has never been higher than 18mpg when driving on a freeway at 55mph (confirmed by a Ford mechanic) significantly below the product advertisement by Ford. To date after multiple times in the Ford dealership repair shop the problem has not been fixed.

F-250 8-cyl Diesel

  • 1,500 miles
2011 Ford F250 crewcab FX4 6.7L diesel engine. Sometimes you push on the gas and nothing happens and it takes a few seconds and it kicks in and goes. Towing a fifth wheel thru a stop sign with a 18 wheeler bearig down on you sucks. Almost didn't make it out of the way. This happen twice in one day. The dealer heard noise from my fuel pump so the they changed the fuel filters and I had a recall for some computer upgrade data thingy. I only have 24K miles and this has happened a few other times without a load on it (towing or not). Did I just spend $61,000 on a death trap"? at the diesel website, there are many other people with this same problem. I have taken my vehicle in to a dealer and they say "can not duplicate" but this happens every now and then. One person on that forum was able to take a Ford mechanic driving with him and was able to duplicate the problem but later the mechanic said nothing was wrong. Sounds like a cover up to me. What should I do?? just keep taking my truck in to the dealer"
