Complete power loss when making right turn

[150ish]

Old thread.. any update or resolution?

I have a PB that will do that when the right rear wheel cuts the corner and looses traction as it cuts over the lip/ drop edge of a sidewalk. Traction control cuts throttle response momentarily. Only happens if the rear right wheel hops the curb a bit, not on flat turns.

Totally different than the traction control kicking in.

Funny you asked. I'm dropping it off today. It happened to me again this Saturday. I almost died in a roundabout. We will see if the issue gets resolved.
Mine is a PowerBoost.

Powerboost for me.

Actually this sounds very much like the active stability control kicking in, which is fairly easy to trigger when driving with a bit more passion like the OP seems to do. It tries to prevent too much lateral G’s that could be risky, therefore occurring mostly in curves under boost. The outcome is a feel akin to a dead gas pedal.

LOl, I drive with zero passion 99.9% of the time. The power loss happens under normal driving conditions. But only when making a right hand turn.

That’s just traction control operating as designed. Some manufacturers are more aggressive with it than others, but I have to say I haven’t noticed mine being over aggressive in normal driving. When I had my mustang I got used to clicking the traction off button when I knew I’d be making a somewhat risky maneuver and needed the computer not to cut the power

You said it happens in turns though, and I would agree with the members above: It can very well be the electronic stability control that cuts power. This system can be triggered quite easily and the description would fit. But it being your average Internet forum diagnostics, you'd probably want to check with a dealer. FYI Traction control is not the same as stability control, they are two different systems.

Yes, under normal driving conditions. Meaning non aggressive right hand turns. I get no lights of any kind when it happens. It just completely dies for about 3-5 seconds. I hit the gas pedal to the floor and get nothing. No RPM change, no forward movement, nothing. There's obviously something wrong. I cant see them designing the truck to respond that way.
I did drop it off yesterday. Now its the waiting game.

This is definitely not traction control. Totally different feel to it.

Last week we were up in the north GA mountains with our Odyssey and the rental cabin was up some pretty step gravel tight roads. Many times going up hill the traction light would blink, the tires would spin, and occasionally even with the pedal to the floor, nothing happened for a few seconds before it would start to pull again. This is the only time I've ever lost power in a vehicle and it did it every time we went up a certain nasty incline and lost traction.

The key there is the light flashes. I get no lights. I offroad my truck and definitely know when my traction control is the issue. These instances have taken place on dry roads with zero wheel spin or aggressive throttle.

Christ almighty, that is frightening. I've been fighting with myself on whether I should get a Powerboost now instead of waiting on a Lightning. You just cemented my decision for me. No way.

You could just as easily find yourself in a lemon of a different truck. There's plenty of very happy Powerboost owners here.

The problem sounds pretty specific and also very intermittent, you could have so many things causing it in the new trucks, it's really too bad there's not a black box function for all the systems where you can save all the data to analyze, even if no codes come up. In some of the systems, codes are triggered only after a certain duration of malfunction or after a certain quantity of malfunction. Under that factory set threshold and you have little to go by.

It could have nothing to do with the electronics at all, nobody has mentioned fuel pressure yet. Do you have full or empty tanks when this happens? The fuel pump chugging some air or getting clogged for a moment can result in a momentary loss of power before pressure builds up again. There could be a loose or missing part in the fuel pump.

It could also be a mechanical fault, the accelerator pedal assembly is throttle-by-wire and there could be a piece hanging up or broken that needs a very specific condition to malfunction.

Same thing with a wire with a fault in it, there's a few people that have had wiring problems in their trucks caused by awkwardly run harnesses or crimped wires. One guy found his wheel speed sensor wire had come out of he wire keepers and gotten chewed through. That's a very obvious problem but the hard ones are the wires that either weren't manufactured right or suffered some kind of trauma before being bundled up and installed in the truck. I remember popping the hood of my truck to diagnose a misfire and as I was unpacking the OBD computer, a mechanic walked up to me and mentioned that the owner of the shop had fumbled and dropped one of the brand new spark plugs right onto the concrete floor. Of course, it was the cylinder all the way in the back under the brake booster/master cylinder.

Good luck, hopefully it will be an easy fix!

Sure, that's true but the car I have right now doesn't do that. It's more that I don't NEED to buy a truck right now, I just WANT to. I feel like there are going to be more gremlins and bugs in 21/22s because of work stoppages and commodity shortages.

So my heart says "F yes get that truck now" but my head says "WAIT you moron, your car is paid off and perfectly fine." I don't want to potentially deal with this kind of thing if I don't have to.

I do hope this gets resolved ASAP though. Sounds very unsafe.

I wouldn't let my experience sway your decision. I would buy another PowerBoost in a heartbeat. I just chalk it up to a new design and some bugs to work out. I don't typically buy a truck when its in its first year of model changes.

Aghh don't say that man. I finally convinced myself to wait. D:

I swear I've changed my mind about this truck 100 times already.

...It's more that I don't NEED to buy a truck right now, I just WANT to...

That's the best reason for not spending money on a new truck, people are lined up to pay MSRP and over at dealerships now. I stopped by my local dealership this past weekend to test drive the new Bronco and they hinted that with the low mileage and condition of my truck, they would buy it for more than I paid. Which is crazy!

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.

...I would buy another PowerBoost in a heartbeat. I just chalk it up to a new design and some bugs to work out. I don't typically buy a truck when its in its first year of model changes.

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?
