2024 XLT 2.3L power loss going around corner

[CoryB]

This has happened to me twice now, once turning in each direction.

I rounded a 90 degree right-hand corner without having to stop (the light was green for me) and the truck lost all power for (a very long) 1-2 seconds. The accelerator pedal didn’t respond. The truck just coasted. Then, just as suddenly, the pedal responded and off we went.

Yesterday I turned a left corner from one road onto another (no stop sign) and the truck didn't respond to me pressing the accelerator pedal. No “Check Engine” light, no errors, nothing. Then it took off after a couple of seconds like nothing was wrong. The same thing happened tonight but while turning right so it’s not direction dependent.

Of course I cannot make it happen at will, it’s just totally random.

The truck has under 1000 miles (7xx) on it. Gas level was ~2/3 of a tank of Exxon 87 octane. Outside temp was in the 60s and the truck was fully warmed up In both cases.

Any ideas? I’ll be calling the dealer tomorrow.

Sounds like traction control is limiting power?? Did you get flashing yellow traction light while you had no power?

Try turning it off or don’t press down so far on throttle while mid corner?

Interesting thought. I didn’t notice any lights but I’ll try driving with the traction control off and see what happens. Thanks!

Yeah sounds like traction control. Speed, wheel slip, steering input, vehicle lean and throttle input all factor into traction control. My guess is you upset it by either being too quick, too much steering input or it detected too much lean or wheel slip

Seems like some control unit calculations being performed to determine which gear to select. Once the gear choice was determined, the trans downshifted and away you went.

I've had this happen several times as well. 2.7L V6 here. After rounding the corner the accellerator is dead for 1-2 seconds. Very disconcerting. I can't duplicate either. Dealer service dept shrugged their shoulders.
It was not in wheel slip, no traction control light no downshifting that I could detect. Just dead accellerator pedal.

Could it be some sort of ESC / rollover protection?

I doubt it. I wasn’t going fast but things just stopped happening. Last night I was watching a YouTube video and the person said the shifting in Normal mode feels strange to him, but it’s fine in Sport mode. He said it hunts or hesitates sometimes in Normal - which is what this could be. I may try driving around in Sport for a while and see if it happens again.

If you find a way to reproduce it, also give it a shot in manual mode.

I'll hit some corners a bit harder today and see if I can get the same thing to happen.
