My 2008 F-250XL gas auto ran away with me this AM twice after church. Once I slowed and stopped at a stop sign. Then the engine took off on it's own an rev'd to 4000RPM+. I held my foot on the brake but the truck shoved out into an intersection before I shifted to neutral. It rev'd even higher and then went back to a smooth, stock idle. NOT FUN. NO fat foot issue or mats. It has a rubber floor. Ten minutes later after a deposit at a local ATM upon start up, in reverse, the same thing played out but I had to shut it down to get things under control.
Questions.....

1. Is there a history for this problem with my year and equipment?
2. At 17000 miles and 3 years, 1 month on the clock is it a warranty repair?
3. Does the truck's event recorder have a record of this the dealer can pull
up?
4. Would an OASIS report show this problem if the previous owner reported it
on a dealer visit? Would a lemon law by-back show up there?
5. Any diagnosis based on experience? Again...NO fat foot issue. My foot was
clearly on one pedal at a time.

Thanks Folks! I want to be prepared for my dealer visit and not get the "Could not be duplicated" response. The truck could have killed somebody. This is a big time safety issue that needs resolving yesterday!

 

well my co-worker swares up and down that happend to him with our 05' f250, gas,auto, shop truck. it was in the shop when he started it up, put it into reverse and the engine started screaming, he panicked and jammed it into park, I heard all that noise and asked him what happend, also happend to him twice in a month. I asked him if it was the old right foot on both the gas and brake and he said no way. the supervisor never bought thet truck in....but your post old fudd is the second time I have heard of this...please let us know what happens with your truck... I guess our supervisor at work did not belive my co worker, but it should have been bought in to have it looked at

 

The only time it has ever happened to mine was when I had first bought it. I switched from a 2002 Silverado to a 2008 F250. The difference was that in the Silverado I could fit my foot between the gas and brake pedals without touching both... in the F250 I can't.

The first two times I heard it (heard not felt because the clutch was always in) I thought there was no way I was fat-footing it... sure enough I was wrong. It doesn't take much pressure to mash the gas.

 

No
Yes
Maybe
Yes
Possible Throttle Position Sensor issue, or perhaps it was a fat foot issue. If it was a fat foot issue you'd swear it wasn't. No one would intentionally step on the gas in these instances.

 

shut off the key first.deal with the rest later.

 

I would think the dealer would be able to see the redline of the RPMs, plus the max speed of the truck. Using that info then they should beleive you.

Should be code in there for max RPMs.

 

2010 E-450 V10 in a Winnebago Outlook 31C RV has continued high RPMs when braking for a stop requiring extreme braking force and necessary shift to neutral which causes even higher RPMs until key is turned off. Two incidents [23 May 2011 and 20 June 2011]?? Not "Fat Foot" - two different drivers have driven this and another V10 for 12 years. Not "Floor Matts" - Matts were in place and secure. Been to dealer - "Could not duplicate the problem" with two test drives and advice from FORD Hotline Request. No Error Codes.

 

I'm with Redford on this one. I've revved the engine and sworn to myself I couldn't possibly be stepping on the gas, only to figure out that I was, with big winter boots to blame.

However, in terms of mechanical causes, how about a dirt/carbon build up in the air intake interfering with the throttle closing?

 

Had a runaway 2 times now on a FORD V10 E-450 May 2011 and June 2011. Currently working with dealer to resolve.

 

I would get these trucks into the dealership ASAP. There may be a faulty part and is definitely a safety issue.

 

Just a thought, I had a car and the cruise wouldn't shut off going down the interstate, I was young, inexperienced and it scared the bejesus out of me, I pulled of the ramp put it in neutral and slammed on the brakes, shut it off, caught my breath and I've never used cruise control again. I'm thinking maybe your cruise may have switched on some how, just a thought?

 

Definitely take it to the dealer. Remember this happening to Toyota a few years ago? Somebody was the first to experience it and report it to Toyota.
