Complete power loss when making right turn

[JTmass]

The other side of the coin is that Ford can only eat so much of the costs before inflation forces them to raise prices. They might be able to hide everything in the options but if things get worse in '22, we might see a significant increase in prices for all manufacturers. A base XL regular cab, no options might be tickling $50K, with loaded trucks well over six figures

That's part of the reason I'm struggling with this decision. I can order now and get a screaming good deal. I have to wait but that's fine with me. I worry that my current car's value will decrease where it makes it harder to buy the truck when I'm ready. I worry that prices will go up. Right now everything is too expensive.

I will just pay down debt and save in the meantime. WANT isn't a good enough reason to buy the truck right now. I'll just wait for the Lightning.

I rarely buy new model year trucks either but I was too late to order a 2020 and I was really looking for a used truck but they were next to impossible to find in the configuration that I wanted even before all the craziness.

The gremlin might not even be Powerboost related. When you lost power, did you feel the engine running rough at all? Did they happen when the truck had a certain amount of fuel?

The only common factor when it happens is making a right hand turn. Its typically when I'm half way through the turn. No weird noises, no lights, no sounds, just complete loss of engine power and RPM's. The only thing I can figure is somehow it gets stuck between EV and ICE. Or, the trans is somehow screwing it up. My low speed shifts into 3rd gear can sometimes be rough.

I’ve experienced the power loss as well, while pulling out onto main roads in a right hand turn.
Postings have referenced aggressive driving, and I do recall that the circumstances were associated with quick actions/ acceleration, sharp (relatively) turns, potential tire slipping, as well as sometimes uneven surfaces associated with crosswalks or drives perpendicular to the road.
I’d be interested in hearing from earlier posts, who had Ford shops investigate(ing).
The experience(s) were not confidence building.

Hey! Could you please send over a private message with your VIN and some more details about your power loss experience? I would like to see what I can do to assist.

I get the power loss as well but I get it when in a slow roll and in EV mode and when I turn left or right I get a delay like it's deciding if it wants to go to gas or not. Takes it a couple of seconds. It gets a little unnerving when you turn left and you have traffic heading towards you. It really has me considering trading in this truck if that's operating normally for the powerboost. That and I'm only averaging between 19 and 20 MPG and I am not an aggressive driver at all.

Wondering if you guys ever found a solution to this problem. I've had this happen a few times, but I had my first particularly close call this morning, and I got a little spooked about not being able to accelerate. I really do not understand how some of the quirks on these trucks got through engineering and testing.

Hey there! I can look into your F-150’s power loss concerns on my end if you’d like. Will you send us a private message with your VIN and dealership info?

Is it a hard turn like maxxed out. If so Im willing to bet a voltage issue. The steering is all electric maxxing out the turn I bet triggers a low voltage issue and causes it to bog the system down.

The early trucks had shit batteries. Not bad to where the truck wont start but bad they dotn deliver high current when needed. Id like to see what codes he has

I didn't think there was a correlation between turning and the power loss until now, so I have not been paying attention to that aspect. I will definitely report back regarding the degree of turn if/when it happens again.

It definitely feels like the truck can't decide if it should start the ICE or stay in electric mode, and it hiccups for a second while making that decision. Very unnerving, especially now that I'm carting around a wife and two young kids.

I can ubnderstand it. Honestly they had a bad batch of batteries.. Id sufgest replacing it and seeing if your issue goes away. The dealers will not replace them. My truck has been much better since repplacing the battery

You think a Jan. 2022 build would be affected? Maybe it's just from sitting for three months in a lot during production?

Did you replace with the OE battery or aftermarket? Just the 12V under the hood, right?

 

[Jesse-Infotainment]

Yeah New OEM battery. Yours being a 22 I have not seen them suffer with the battery issues. Next time pay attention if it happens how hard of a turn you are making. We can go from there.

I have had this issue multiple times as well for about 20k miles now. For me, it is usually on left turns crossing one lane of traffic but have had it happen on right turns as well. Multiple dealer appointments with unable to duplicate. The Ford account on here reached out to me on thread "lag then quick acceleration" and had a specialist work with the dealer but came back with it would be fixed with OTA updates that were scheduled for Feb and July for things not related to the issue. Those updates came and issue still exists. Dealer still responds unable to duplicate so nothing they can do. If anyone has had this identified or remedied, please share your experience.

 

[thebigdu]

I had this happen again this morning and was, once again, almost in serious danger due to a complete lack of acceleration for about two seconds. Did anybody ever find the solution?

@Jesse-Infotainment I did confirm it's *almost* always when making a sharp turn. Should I just replace the 12V under the hood, or do you think I'd need to replace the aux battery under the rear passenger seat, as well? (PB) Thanks!

If I were you I would charge the battery over night. Make sure its fully charged and see if the problem persists. If you are able to duplicate it pretty easy then it would be a good way to confirm.

If you have forscan possibly go into the PID and check the Battery SOC(State of charger)

The steering rack is fully electric and it makes sense it does it in a fully locked turn because its pulling the highest amount of current. So much so it starts to drop below the operational levels of the other electronics.

Or you could just replace the battery and see if it persists. It would be best to try and confirm somewhat though before spending thre money
