6 times in 10 years? I am sorry, but you should have addressed this long before now. Fords lawyers will argue the same fact. I think you are losing before you begin. Sell it and buy something else, and when you do, let the next owner know of the problems if you are that scared of the truck and what it "might" do. Best of luck.

I am not part of a class action suit. I am honestly saying that our truck has behaved as described by some of the people in the articles that I read on the internet about it. The Ford Customer Service Rep. initiated the claim the other day, not me. I called in to let Ford know about the sua. After putting me on hold, she came back to the phone, adamant about us not driving the truck, even though it was running normally, engine light unlit. She said to get it towed right then, but we had to get home. She strongly suggested not driving it home and she told me to get it towed to a service shop asap after we got home. The regional customer service manager who took the case told me, the tow is free, the service estimate will be free and any repairs will be at our cost...But if there is a recall, we will be reimbursed. She/He (Ford) told me they know nothing about sua but it seems like they are taking it seriously...I have to ask why?

F150 sudden unintended acceleration is what I typed into my internet browser for information about sua.

It would act up for a few seconds and then many months or years would go by before it would occur again. The engine light never lit. It left us wondering if it was a fluke or if it just straightened itself out. The service manager said if they cannot replicate the sua and no codes appear, they won't be able to fix it. This truck is the most expensive vehicle we've ever owned. I did call about it. We had the truck serviced. It never showed up. I've been in here too long. Goodnight all. Take care.

OP I don't believe a word you say. I never had an issue with my 07. Like I said your pissing in the wind. If this really was a problem why didn't you have it looked at after the first time. You are not gonna get a single cent out of ford especially with a 10 year old truck

I'm not gonna bash on the experiences you and your husband have had with this truck. There are 3 things basically that regulate and affect the drive by wire system. These are things you can easily check and/or replace. First check that there isn't anything binding your gas pedal. The signal that comes from the gas pedal are read at the PCM and sent to the throttle body assembly. The PCM could be the culprit as well could the throttle body assembly OR a faulty throttle body position sensor. Take the time to remove the throttle body and use a THROTTLE BODY cleaner from your local hardware store to thoroughly clean the throttle body. Replace the throttle body position sensor with a new unit and install the assembly back on the truck. While you are at it remove the MAF sensor and spray it out with MAF SENSOR cleaner from your local hardware store. Then reinstall it.

IF this doesn't cure the conditions you describe then the fault could lie in the PCM or the gas pedal assembly.

Please try to do some preventive maintenance before someone indeed does get hurt.

Thanks Mdgonzo101.

What do you make of the class action lawsuits alleging that Ford vehicles were subject to sudden acceleration and lacked adequate safety mechanisms (no brake over accelerator/brake override system) to prevent crashes that were filed in the Southern District of West Virginia U.S. District Court and in a West Virginia federal court last year?

Our truck was towed to the local dealership service department yesterday. I got a call from them asking me to describe the sudden unintended over acceleration occurrences we've experienced while driving our 2004 F150 4X4 Lariat. A service mechanic is going to take it home and drive it around to try to replicate the problem. I told him to keep his distance from other vehicles on the road and please be careful. John, from the service department, said they can somehow get freeze pictures? of what is happening if the problem replicates.

Thanks again for taking the time to post this helpful information. I've passed it on to John, in the service department and to Jim, my husband.

Default Update

The mechanic said he could not replicate the SUA. He test drove our truck over 200 miles. We were told by the service department that no maintenance or work needs to be done on our truck and they wrote that our truck is safe to drive on the receipt. The dealership is happy to take our truck as a trade in, if we chose to buy another truck there. Ford, the dealership, the employees all say they never heard about SUA in an F150, but I told them. I am nobody to them.
Recently, Ford Motor Co. tried to get the class action suits against them dropped. The class action suit claims that some 2002 - 2010 Ford, Lincoln and Mercury vehicles did not have and should have had a "smart brake" or brake override system in the vehicles so drivers could stop sudden unintended acceleration by using the brakes continues to go forward. The judge did rule that plaintiffs who bought their vehicles used can not be included in the lawsuit because there is no proof that they paid more than the vehicles were worth and Ford Motor Company did not benefit from the sales.
We have always liked our 2004 F150 and people always compliment it. We hate to give it up, but it looks like it is time to.

Hi.

Ford's ETC has several redundant sensors, two return springs on the TB, software that is separately cross/sanity-checking those sensors, a completely separate subsystem in the PCM ( eQuizzer) to oversee everything ETC related, and a host of codes to help diagnose it.

The slightest discrepancy will immediately put the truck into the Forced Limited Power state - a.k.a. Limp-Home mode - with barely enough power to move the truck, let alone agressively accelerate it, and easily stopped via the brakes.

I'm not surprised they did not find anything as this software has been thoroughly debugged over the years. Without a code or codes, and the lack of a Limp Home event or trigger, they'd need to replace every single component. They won't do that on a 10 year old truck, unless it's on your dime.

I personally have not seen any reports of this on an F150 - always a first time, I suppose.

Some reference info here: http://www.underhoodservice.com/Arti...e_control.aspx

Lastly - please be aware that most all manufacturers have already or are adopting drive-by-wire throttle systems.

good luck
MGD
