Truck accelerated from stop and rear ended car in front.

[Adventureboy]

It is scary that there are more than a few cases of this. I've had the case where I've touched the resume button while turning in a parking lot once and had to hit the brakes frantically. I turn cruise completely off now when I exit the highway.

For the OP - immediately have the truck investigated. If the impact was hard enough, it would have recorded many of the parameters at the time of impact (ie. throttle position, BlueCruise status, brake status etc.). In your case, it may not have been a serious enough incident for the truck to trigger the capture, but it's worth a shot. I'd sure want to know.

I too have had the unintended acceleration by accidentally pressing the cruise control button. It seems to be very sensitive, th slightest graze and bam the car takes off. I have had this happen about 4 times now in a year, once while in a parking garage. I have learned to make sure the cruise is diabled as soon as i exit the highway. I have never had this happen on any other car. I know its my fault for not tirning the wheel "properly", but i am the only person that uses the palm of their hand when making tight turns?

I played around with this today as I thought some of the behaviors people claimed seem kind of dumb (the behavior, not the people), for example, I thought you had to go a certain speed to activate cruise control for example...

So the most interesting observation is that if you drive up to speed and then activate cruise control only to later disengage it with the cancel button or by braking... if you then later come to a full stop and you try to resume you get two different behaviors...

If there is no one in front of you, it'll basically say "can't activate, moving too slow" kind of as expected.

But IF there IS someone in front of you, it'll happily activate cruise control and as long as the car in front starts moving within a second or two, your truck will just GENTLY take off after the car in front.

If you remain stationary for more than a few seconds (with someone in front) it will activate, but then deactivate with a "stopped" label on the dash.

Additionally, if you have speed sign recognition, the truck continues to track speed signs even with the cruise in standby.

This happened to me when I first got the pickup. A few things i noticed. If the car in front is at an angle the pickup seems to disregard it and tries to quickly accelerate back to previous speed.

The other is having my foot rest on the accelerator when stopped behind another car has had some bad side effect. Slowly creeping up on them which will eventually trigger the accident avoidance warning. If the car in front does a false start and stops again my pickup will jump as well and I have to aggressively apply the brake.

My solution is whenever I'm stopped I rest my foot on the brake. Just think of it as one pedal driving not one pedal stopped.

As far as insurance goes, if you are stopped behind a car and the pickup hits the car in front or the car in front backs into you, if the data in the pickup says your foot was NOT on the brake pedal, you most likely will be at fault.

Happened to me once , truck was almost going to hit a wall but i was able to brake in time.

Second time happened to my wife, unfortunately she wasn't able to brake in time.

I think after some recent updates this issue must have been fixed because i have turned on cruise accidentally a few time after the updates but it doesn't do that anymore

I also posted this to the Reddit group, but will cross post here as I can use any and all information that others can share. I was stopped in traffic on a 4 lane road. I'm using one pedal mode, so my foot is not on the break. All of a sudden, the truck takes off, rapidly. I slam on the brakes, but not in time to keep from rear ending the tacoma in front of me. My husband says he has had the truck take off like this when he accidentally hits the resume button on the steering wheel with his arm. I don't recall this ever happening to me. Anyone ever experience anything like this? Will they be able to download any data from the truck that will explain what happened? Shouldn't the truck have recognized there was an obstacle and either not moved or stopped on its own? Again, appreciate any information or advice that would be helpful. BTW, it just updated to bluecruise 1.4 2 days ago.

I have also seen strange things happen with the one pedal mode. I am still an advocate for using it because it’s great on windy roads. It makes things much easier while driving and it does seem to regenerate a bit more power while driving on the windy road. However, one thing I’ve noticed about the Ford F150 whether electric or not, is that the cruise control buttons are very easy to hit. I’ve had scary instances where I’ve accidentally hit the resume button myself. Still, this is a flaw. Ford needs to address it.

Just a update.. thank-you everyone for your input. In particular, those of you who have had the same or similar experiences. I've compiled some the information and reports and sent them to my insurance adjuster. As yet I do not know what determination they will make. If they assign blame, I will probably pay to pull the black box data. Either way, I will report to the NHTSA. Thanks again for all the helpful input.

Just had this happen to me when pulling into my garage. I didn't even know i hit the cruise control button, but the truck lurched forward and I almost hit my house. I was flustered and turned the truck off before feeling confident enough to try the accelerator again.

The worst part was that i slammed the brakes and the car did not respond. If Ford doesn't want to fix the cruise control button from automatically engaging while at very low speeds, they should at least prevent it from continuing to engage and speed up while the driver's foot is on the brake!

This is a serious problem and has brought me some doubt over a truck I really love.

Are you sure your foot didn't slip off the corner of the brake onto the accelerator pedal? I ask because after taking some time to think about it, I am pretty sure that is what happened to me when I tried to slam on my Lightning's brakes to avoid a stopped trailer a couple of years ago.

The brake pedal does immediately disengage the cruise control.

The brake did not disengage the cruise control in this situation and I was on it hard! I also use 1-pedal and use very little force when parking in my driveway. I cannot be sure on why the car did this, but it felt like the car was speeding up to catchup with an imaginary car in front of it while I was slamming on the breaks. The net effect is a feeling that the brakes are not working and the car is not listening to driver.
