During the winter months my truck will often sit for a couple of weeks between starts. A couple of times last winter my brake pedal was very hard to press on the first start of the day and the push to start kept saying to press the brake pedal. Each time it finally started when I pressed about as hard as I could. Yesterday after a long sit, the pedal was very hard but it started no problem. This morning the pedal pressed down very easily and the normal message saying start in progress or something like that came up and then the screen changed to press the brake pedal. I pressed harder and tried again with the same results. This continued over many attempts to start it. I then decided to try the remote start and got the same result. After about 4 attempts using the remote start it finally did fire up and worked perfectly for the rest of the trip. I will try to take it in to the dealer this week but was hoping someone here might be able to shed some light on the issue. This will be the trucks first trip back to the dealer since I bought it new so it has been very good so far.

you may have a break sensor issue. pedal being hard after sitting a while is not that uncommon since the vacuum has had time to leak down. one thing you can try is driving with the CC on and very lightly press the break pedal. if it doesn't disengage CC then you may have found your problem.

Mine did the same thing - it was a weak battery. Battery replaced problem gone.
Hope this helps.
Helps if you leave the battery plugged into a battery tender/charger. Not sure if this has anything to do with your issue but the charger will eliminate a lot of potential issues.

Not sure the F350 has "vacuum" as I think it has hydro boost setup which is different than those vacuum booster units furnished on the F250's
Thanks for the responses. I have used the truck a lot since the issue this morning and everything appears to be working normally. Yesterday was very cold so the truck was plugged in for a few hours and it started right up with no hesitation or slow cranking at all so I don't think the batteries are down by much.I also did a lot of highway driving yesterday so the batteries should have had a full charge this morning when it acted up. I did use the cruise control today and it was cutting out fine when I touched the brakes and the lights do come on. Would it not start normally with the remote start even if the brake switch is faulty as the brakes are not being applied during this process? I am concerned that it is going to be one of those can't replicate responses the problem from the dealer when I take it in.

I took the truck in this morning and just received a call from them. As I expected they are unable to reproduce the problem so nothing can be done. They will try again in the morning but there is little chance it will act up for them. It takes weeks for the brake pedal to become hard so I don't think there is a leak in the system. The fact that it would not start using the remote start which does not depend on the bake pedal being depressed tells me the problem lies somewhere else. I will let it go for now, but if it happens again I will lean on them a little harder. I also had them look into the rattle in the top front corner of the drivers door but since it is also intermittent they couldn't reproduce it. On the plus side they are going to fix the drivers seat because the center panel in the seat is all wrinkly. They have ordered a new seat cover and seat foam. At least the trip in wasn't totally for nothing.

You might be on to something. The remote start uses Park sensor, the neutral sensor, and the brake pedal for the push button start. One th No you can try is shifting from park through neutral to drive and back to park and retry the start.
and for long sits, definitely put them batteries on a trickle charger if more than a few days and see if it still happens. There are lockouts for battery voltage. So I wonder if checking battery voltage before starting after a long cold soak is worthwhile.
When you get in to start the truck and apply the break and push the start button, if you have memory seats, wheel etc., do they move into position, without the vehicle starting ... and then give you the message to apply the brake to start?
I ask because my remote start was acting up (it would just make a sort of a popping sound but the truck wouldn't start) then my start was intermittent and it would do as I described above. I would get in apply the brake, hit the button, the wheel and seat would adjust and I would get a message to apply the brake to start the vehicle. I experienced a similar issue to what you described with the brake, Sometimes it would start, sometimes not at all for a few minutes after this routine. After a few trips to the dealer and a video that I took of what was happening. The service tech told me that by watching the light sequence on the button (it flashes a particular pattern I guess) that indicated all systems prior to starting should have been in place for the vehicle to start. In the end ... I needed a starter.

I will keep this in mind.
They are keeping the truck for a few days to see if sitting in the cold will trigger anything.

Since you have the push to start and the problem is intermittent you need to check if the lights come on while you are pushing the brake and having the starting issue. When you were driving the other day the truck obviously started so I would expect the brake switch to be acting normal, cancel the cruise etc. When it doesn't start and is telling you to push the brake, then check your lights. Then you will know for sure if the brake switch is sticking intermittently when its cold. A brake switch is either on or off. If you are pushing the brake it should be on and the truck should not be asking you to push the brake pedal.
