I have a 2018 F150 XL 2.7l 4x4 with about 2400 miles. Today, I was driving and lost all engine power. An error message popped up on the instru
ment cluster saying "Auto StartStop Shift to P then restart". The truck was cold and had been sitting for 2 days. It's been about 20 degrees during the day and 0 at night. I had started the truck, let it warm for a minute then drove a mile and parked. Fifteen minutes later I started it and pulled out of a parking spot, slowed at the end of the lot and was pulling onto the road when it died and I got that message. I took a picture then put it in park and it restarted fine. I drove the mile home with no issue.
I have not gone to the dealer yet as I suspect they will just tell me to wait until it happens again. Any thoughts on what the problem may be?
My 2020 F150 with the 2.7 ecoboost did the same thing to me the other day. It was the 1st time it has happened and has not happened since. I was stopping at a red light and it completely lost power. The truck did however start right back up with no issue. It is just very concerning as I just purchased the truck 1 month ago and it only has 28,000 miles on it. I took it to the dealership as it is still under warranty but of course they said they could not find a thing wrong with it. I need answers on this.
Thank you for posting this. I just now filed a claim with them through this link. I took my truck to the dealership and of course they said they could not find any issue at all. I have only had my 2020 f150 for a month now so I am very concerned.
I took my truck to the dealership today for the 1st time over this issue and they tested my battery. They told me everything with the battery and the Auto Start Stop feature was fine and working properly. So Im not sure why mine did this.
One fail to auto start and your running to a dealer!!!????Take a look at the previous replies and see all the items that can be a temporary cause.
yea I went to the dealer. I have only had the truck for a month and it completely quit on me in a intersection. Yea I feel I have the right as a customer to have questions and be a little pissed off about it. My silverado I traded for the Ford never did that.
The truck has done this to me again. I posted about it on here a few weeks back. Since then I took it to the dealer and of course they could not find any issues. This time I wasn't even at a complete stop and it did it. Lucky for me there was no traffic as this is typically a very busy intersection. I have talked to Ford directly and of course they act like they have never heard of this issue. This will definitely be my 1st and last F150.

Especially in very cold temperatures, just cranking the engine and taking off on a drive, there HAS to be [enough time] for the system to recover the battery charge to 'above' the minimum SOC charge or the Auto stop start will fail.
A normal result if the vehicle has not ben driven long enough to recover the battery or the engine has been cranked many times without enough time for that recovery to take place.
The battery has a lot of power stored and gives it up for cranking quite fast, but takes many times longer to replace (chemical reactions) , after a high and or multiple high current drains in short time intervals..
Its the Law of Physics for a Battery.
Auto start failure is NOT an error but a result of the condition present at the time.
Good luck.

I understand all that but this is still an issue that Ford needs to correct. These vehicles should not be doing this and we can't just say oh it's normal. I am beyond upset cause I haven't owned the truck but 3 months and it's done it twice now. Also it wasn't cold out really when this happened or at least not what I consider cold it was in the range of about 45 degrees out. This could very easily cause a accident and when I have my child in the vehicle with me it only Infuriated me more. I got lucky this time but next time maybe not.
2020 Ford F150 Same Issue
