I purchased a new 2017 Lariat F150 in 2017- it currently has 16,000 miles on it. I was 5 hours from home and the truck would not start, it has a push button start, the lights would come on, but it would not turn over. Had to have my spouse drive the 5 hours to get me, my horse trailer and the two horses. The truck was towed to a nearby Ford dealership, I get a call from the dealership that there didn't seem to be a problem - the truck started and drove without a problem. I then picked the truck up and did not have a problem driving the 5 hours home, of course when I stopped to get gas, I did not turn the truck off. Got home -made an appt for the next week for a nearby dealership to look it over. Took the truck out today - drove great, stopped and did not have a problem - went to move the truck when I got home from my errands - and it would not start. Sooo unhappy right now - any suggestions.

 

Need more info - any codes? any noises when you try to start? any messages on screen? in gear? remote start work?

Needs driving more regularly

 

Welcome to the forum, sorry to hear about you issues.
I could be wrong but the computer should have recorded the event, for troubleshooting.

Welcome, sorry to hear about your issue. Not sure if it will be the same but I had a similar issue years ago and had to replace my ecu and had no further issues. Best of luck.

 

Sounds like a BMS issue. (Battery Management System) Take a voltage reading off the battery when that happens and see if a valid reason exists (battery voltage low). There are similar complaints I've read about on this forum, same exact scenario, won't start, later it starts up fine. Some, I've read, have permanently unplugged the BMS connection located on the negative battery terminal to eliminate BMS monitoring control which includes elimination of the stop start function, also controlled by the BMS.

 

If the battery has not been tested, I'd start there.

With 16,000 on an almost 5 year old vehicle, it is highly likely the battery hasn't had a full charge for a long time and you could be experiencing some intermittent failures.
Short trips on these modern trucks actually end up with lower state of charge after a drive due to not driving long enough for the system to recharge.
It sounds maybe like your truck is a tow vehicle for horses and is parked the rest of the time?

It could be a lot of things, but getting that battery properly tested could be a good first step.
Tough situation to be stranded that far from home. I could get a tow or a friend to carry me and my ice cream home from the grocery store but I would probably just have to be homeless and steep in my vehicle that was dead 5 hours from home.

I had concerns a week ago.
I drove to vacation, about 4 hours away. The following morning it was around 40 degrees and the sound of the cranking motor seemed slower. I am driving more often now than Iwas a few months ago, the battery should have a decent charge, back at home where the low is 80 degrees, cranking in the garage 4 days later is fine. But 2 cold Lake Tahoe mornings in a row I was experiencing a slow crank. The battery in my 2016 has been replaced before I bought it a year ago and I don't know how old it is, but I may need to also get it checked out and/or have the battery monitoring system (BMS) reset.

 

Simple things to try yourself....check battery voltage, check battery ground, check starting with 2nd fob, try remote start.

If it's something more complex, Ford service will need to diagnose, unless you have the skills/tools to do so yourself.

 

5 years old, I'd guess it needs new battery.

 

More than likely, it’s the battery. Had the same type of issue with our Explorer after a few years. New battery, and never had another problem.

With as much electronic gear that these new trucks have, batteries just seem to die more quickly. If you get a new one, spend the coin and get a good one. Important component.

 

I bought a new 2020 f150 in September. October 1st it wouldn’t start....yep, dead battery at 1,100 miles!! Ford dealer replaced it and no more issues since.

The service writer told me that the batteries in the newer vehicles are good for about three years, due to all the stuff going on when the truck is turned off. It’s constantly being drained and recharged. Of course, he recommended that batteries be replaced with motorcraft units as ford designed them for the trucks.
