2016 Ford Explorer XLT v6 engine intermittently jerking at high speed and high speed acceleration, no check engine light

[talderink]

My 2016 Ford Explorer started intermittently jerking at high speed (55 +) and sometimes when accelerating at high speeds. A service advisor thought it was bad gas and recommended I add fuel cleaner/stabilizer, run until nearly empty, then refilling with regular unleaded (no ethanol). I added Seafoam fuel stabilizer to a full tank and it nearly immediately resolved the issue. I drove ~400 miles no issues. Refilled at a Marathon gas station (91 octane, but 10% ethanol b/c they did not have regular unleaded without ethanol), and added one more can of Seafoam and it’s intermittently jerking again. There is no check engine light or other dashboard error light. The dealership is not able to determine the issue and wasn’t really able to recreate the jerking. They are guessing it may be the start of a a transmission issue that isn’t throwing a code and having their transmission tech look at it. Anyone else have this issue? Any advice on how to resolve and/or what to do if it really was bad gas (perhaps bad gas with the tank I refilled with)?

Don't rule out a misfire.
My wife's old CX9 had a pretty bad shudder when you'd try to accelerate at highway speeds.
I was convinced it was the transmission since it never set a check engine light.
When I hooked up my scanner I could see the misfire counts go up as soon as the shudder happened.
New plugs solved the issue on that car.

How many miles on your Explorer?
How old are the plugs?
Do you have access to a scanner that can see real-time data?

Welcome to the Forum.
The 2016 model was known to have issues with the throttle body.
