I know now that our 2004 F150 Lariat was not equipped with BOA (brake over accelerator) to safeguard against sudden unintended acceleration. Ford Motor company didn't send out recalls to have BOA installed in their 2002 - 2010 vehicles that don't have it or even send letters out instructing us what to do if SUA occurs.

My husband and I looked at a 2014 F150 XLT, because we can't afford a new Lariat. We looked in the owner's manual and found this:

Brake Over Accelerator (in bold print)

In the event the accelerator becomes stuck or entrapped, applying steady and firm pressure to the brake pedal will both slow the vehicle and reduce engine power. If you experience this condition, apply the brakes and bring your vehicle to a safe stop. Turn the engine off, shift to P (Park) and apply the parking brake and then inspect the accelerator pedal for any interference. If none are found and the condition persists, have your vehicle towed to the nearest authorized dealer.

We are no longer F150 truck owners. I hope you pass along this SUA and BOA information to people you know that drive Ford, Lincoln and Mercury

I also will not bash or detract from your experiences, because I recently read some complaints filed with the NHTSA about the drive-by-wire system in 1998-2010 Lincoln Town Cars having many instances of SUA. While I found this disturbing, I took into account the fact that there were also any complaints about the accelerator and brake pedals being large and spaced close to one another, and considering the demographic of folks driving them, I feel this correlates. As others in this thread have stated, I have also encountered the issue of depressing both the brake and gas pedal at once, which almost ended in a crash with another vehicle. Since the adrenaline gets flowing when such things happen, I didn't realize that I had been depressing both pedals until I had shifted into neutral.

Again, I'm not saying that your experiences didn't happen and I am sorry to hear that they did.

I will say that given the loyal base on this forum, if SUA was a "40%" case on 04-08 F-150's like the article posted here stated, the threads here would be constantly lighting up with many instances of this happening and folks trying to troubleshoot.

You'll be hard pressed to find another newer vehicle that DOESN'T come with a drive by wire system from ANY manufacturer. I'm not saying you won't find one. I am saying they all made the move to drive by wire a long time ago for most of their product offerings.

It sucks you got rid of your F-150.

I can confirm that this woman isn't crazy. My mom's 2003 Mustang has exhibited something similar to this.
Sometimes, while at a full stop the car feels like it wants to lurch forward. It doesn't happen all the time and it's nothing crazy like whiskey throttle. I could feel the engine pull against the brakes though.
She is about to trade it in so I really don't care to try figuring out why it is doing it.

YMMV.

The Ford Motor Company lawyers got the plaintiffs who bought used 2002 - 2010 vehicles and plaintiffs who have not experienced SUA dismissed. The case is still moving forward.

I see over 1300 views on this thread. For those who want to know, I will try to describe the SUA occurrences we had in the 2004 F150 we owned from 2004 - 2014.

Always while traveling very slowly or stopped, the engine would rapidly rev up like it was going to take off or jump forward on us. My husband or I had to quickly and forcefully hold down the brake pedal (never pump the brake pedal), shift the gear into neutral or park and turn off the engine. When the ignition was turned back on, the truck would run well for many months or years before it would happen again. The engine light always remained unlit as if nothing happened...no codes...and our gas pedal never appeared stuck. The whole process was over in seconds or less than one minute.

2004 - 2010:
1. while pulling into our garage.
2. while visiting a cemetery.
3. just after making a right turn onto a busy road.

2010-2014:
4. while hitching a boat trailer to the truck.
5. while pulling into a grocery store parking space.
6. while pulling up to a gas pump at a busy gas station.

When the Ford service department at one of the largest Ford Dealerships in our area said that they couldn't find anything wrong with the truck and that it was safe to drive, we decided to let the truck go.


I hope none of you experience SUA, but if you own any of the vehicles in question, please find out what to do just in case it does happen. I hope Ford Motor Company installs BOA in all the vehicles that need it.

This is my final post.
Best Regards,

A vacuum leak can cause it, also relaxed boot on pedal. Look for a code it you feel it is throttle body or accelerator.

A Vacuum leak can be a really "Tricky Wicket" with sudden excited accelerations. But there should also be lean codes with it.

Aloha from Hawaii,

We appear to have identical problems with SUA and identical problems dealing with the dealership and Ford Corporate. Inasmuch as I am new to the Forum, I cannot tell if your SUA issues have been resolved.

Hi Dave,

Unfortunately no repairs could be made on the 2004 F150 truck we owned because there were no codes that showed up and the Ford mechanic could not replicate the SUA.

After researching SUA, I found out many 2002 - 2010 Ford, Lincoln and Mercury models, including 2004 F150 trucks, have an electronic throttle but don't have BOA (brake over accelerator). Ford Motor Co began installing BOA in the American market in 2010 as a safety issue. However, Ford Motor Co did not recall the older vehicles to install BOA and did not send out letters informing folks what to do in case SUA occurs.

Because it is a safety issue we were compelled to purchase a new truck with BOA. We chose not to buy a Ford truck because we think Ford Motor Co should have recalled our 2004 F150 and all the 2002 - 2010 vehicles that need BOA.
