If you knew how the ETC was designed with the series of controls and redundant inputs/circuits involved, you all would agree that a uncommanded WOT event is impossible.

 

I would defenitely make the NTSB aware of this defect; or better yet anomaly. If they get enough of these they will take action with Ford (in this case).

It sounds more like a QC hiccup to me..... I ain't no engineer.

 

In buying back my F150, Ford is doing the RIGHT thing!! I give them high marks for they decision! I think they unstand even with all the safe guards, nothing is 100% full proof! I also believe the F150 is best made truck on the market, hence my decision to get a new F150 FX4 !

 

While I appreciate your knowledge of the system, my father, a R&D engineer and proam manager for space & airborne defense systems, had an electronic, mutiple redundant destruct system fail on a multi-million dollar missle not that many years ago, requiring multiple jet fighter squadrons scramble from England & US carrier-based fighters to shoot it down while over the ocean. Not that the automakers don't use the absolute best electronic processing systems and software programs, but if the "best" engineers with the best technology can have failure which is tested far beyound vehicle systems are, it is very difficult for me to believe that it is impossible (though very rare) that a vehicles e-management system could not induce a sudden acceloration event.

Just one persons opinion.

 

my brother, who is having severe vibration issues with his 04- has the opposite problem of you!. he'd be driving down the highway and his brakes would apply themselves. he would be forced to pull over, until they released themselves. he said the rims were so hot you could not even touch them!! of course, the dealership could find nothing wrong. he wouldn't let his wife near the truck-to drive it!! he is in the middle of a buy back procedure with ford!!

 

Defects are not QC problems. Quality is built in, not inspected in.

 

Beechkid,

This missile was military, correct?

If that's the case, it was made by the LOWEST bidder. What costs were cut in making the missile?

If this missile had to be destroyed by fighter aircraft, it would appear the low bidder of the missile, purchased the "range safety package" from the low bidder also.

Missile test are conducted on "safe" routes mostly void of people in case of accident. Vehicles with ECTs are driven on public roads.

All I'm saying is, you can not compare a "missile" made for the military, to a vehicle that involves the safety of the people who drive it.

I agree with new2004Lariat. The ETC should not do this by design.

Take your pick, drive by wire or fly by wire, both systems work better than what they replaced...

 

I would say the electronic system on the Fords, or most any car, are made by the lowest bidder also. Does anyone really think Ford would pay a lot more per vehicle just to be a little safer? They do have a value set on a persons life.

If the cost of the extra components during the life span of a paticular vehicle are going to be more than the expected payout for deaths and lawsuits, then the cheaper compomets are used. Then, when sued, undisclosed settlements will be made with the victims or their heirs. It is cheaper to the company that way. It may sound calloused, but that is the way big business is run. Dollars and cents are always the bottom line.

Now, my brother in law has a 2005 Focus. He has told me several times that every so often when he tries to back up his car will suddenly accelerate, even before he touches the gas pedal. I mentioned this forum to him tonight and he confirmed that his did it again this week. He says he will not back up without one foot on the brake for this reason.

Fail safe engineering or not, nothing is fool proof. I just don't like drive by wire the way it is engineered into gas engines. I have driven electronic diesels for several hundreds of thousands of miles with good service, but it is a totally different system.

If gas engine engineers could work out a direct injection system and do away with throttle bodies, then a lot of problems experienced by people would be eliminated. Asking a system to increase injector flow into an intake, and have a motorized throttle body operate in harmony with the injectors and all the other sensors is asking a lot.

I have a feeling different fuel systems are in the works. Too many throttle bodies fail and are replaced under warranty. Remember the old throttle body injection system, it has gone the way of the carb, and so will the system we now have.

 

I think we are both actually saying the same thing but from a different perspective....components are only as good as the assembly & installation processes, the more time that is spent from design through installation the better the final product is. In this case with sudden acceloration, while driver error is usually the probability (more than likely), I cannot eliminate the possibility (less than likely) cause could be product related, especially sicne there are 6 environments electronics really do not "like"- heat, cold, dirt/dust, oil, vibration & static electricity, all of which there are design processes that as you are also aware of that eliminate or minimize those "influences" that lead to component failures. You are definitely right about the drivability of the new vehicles, when they are right on they are incredible but for the few that have intermittent problems, they can be nightmares. Sometimes I look at a Model A and wonder if we haven't lost just a little bit of henry's vision.

 

Had a coworker come in this morning and describe this same very issue (2006 F150 King Ranch 2,700 miles). He almost ended up in a revine last night. Came into a parking spot foot on brake (checked to make sure foot was NOT on accelerator) and the vehicles RPM's jumped to 4,000, held foot on brake and truck still jerked forward. He grabbed for the shifter and engaged it into park.
This was the 3rd time this has happened.

I think we are developing a common theme here, he will be contacting NTSB and the dealership it was purchased from.

 

Mmmmm...

More interesting.

Does anyone have the circuit diagram for ETC?

I'd kinda like to take a look at it.

I checked the NHTSA site and it shows 5 complaints for "vehicle speed" that references uncommand acceration. That's for 2005, none for 2006 model year.

Each case commented that dealer could not duplicate the problem. They probably will not admit to the problem unless they can duplicate it.

To anyone having seen the problem, were there any mods to the truck, i.e. re-flash by dealer, use of a tuner, re-chipped....?

 

Talked with coworker, his 06 is stock, no mod's. He called his dealer and they told him "just a sticky throttle cabe" bring it in.

 

throttle cable eh? I wouldn't have even took it to the dealer, I would have called Ford Immediately if thats what he told me...

Thats a lie if I have ever heard one...

lmao at this: you have to have a cable for it to stick

 

Nissan was having this issue when the introduced throttle by wire on the old style maxima. Its nothing new, computers malfunction all the time.

 

My 2005 F150, was right out of the box, NO Mod's and it happen four times in 1,000 miles! I hope my new F150 is a GOOD ONE!!
